The thimble in the plastic mold is easy to rust when used. At this time, if not treated, the service life of the thimble will be quickly consumed and become less durable. So what should the plastic mold manufacturer do when the thimble rusts? And how to do it right? NITONI changsha borun, a mould and accessories manufacturer, thinks thimble can be rusted: 1. in the production of plastic mould thimble rust is a large part of the reason why injection water, the machine stopped running to close water is not possible, the improper operation is very easy to cause the thimble rust, right way should be shut off water to close the machine, so it can effectively prevent rust. 2. in addition to using nitride thimble, thimble lubricating oil in die casting time, before each downtime, use cleaner after cleaning the mould, spray anti-rust oil (spray) when the thimble ejection, also can reduce the thimble rusty. 3. If the thimble is used correctly, in fact, the thimble will be hard to rust. When the thimble is discontinued, we should also take good measures to preserve the thimble and use anti-rust oil or machine oil for anti-rust treatment. 4. if you are not careful thimble rust, if it is a mild life, can be rust removal by copper wire or sharpening stone processing, but if rust is severe, or change in time new thimble, so that your mold is in good working condition. After reading the above analysis on the cause of the rust of the ejector pin, do you think that we can effectively avoid the rust of the ejector pin through our usual working habits?

In the era of industry 4.0, more and more mold manufacturers have paid attention to mold parts, especially in injection molding, stamping, casting and other fields. A high - quality mold parts, like a set of molding mold of the viscera, they also have a different mission. So, taking injection mold as an example, let's look at the structural composition of injection mold and the role of each part: 1. Molded parts Concave die (cavity) : a concave part forming the surface of a plastic part. Concave plate (cavity plate) : a plate part having a concave outline on the surface of a face shaped plastic part. The part that is placed in the die setting section is called the die setting cavity plate. The part of the moving die placed is called the moving model cavity plate. Core: forming convex parts on the inner surface of plastic parts. Side core: forming part of side hole, side concave or side convex platform of plastic parts, which can be pulled out and reset manually or with sliding block. Insert: when there are parts in the die or core that are easy to be damaged or hard to be processed as a whole, they are made separately from the main part and embedded into the local forming parts of the main part. Movable inserts: according to the requirements of technology and structure, moulding must be carried out together with the plastic parts to separate the forming parts from the plastic parts. Block: a number of forming parts manufactured separately for the combination of a concave die or a core, which can be called a concave die block and a core block respectively. Threaded core: a forming part that forms the internal thread of a molded part. It can be a movable threaded core (outside the die) or a threaded core that rotates within the mold. Threaded ring: a forming part that forms the outer thread of a molded part. It may be an active threaded ring (integral or combined) or a threaded ring that rotates within the mold. 2. Guide parts Guide post: a cylindrical part fitted with a guide sleeve (or hole) mounted on the other half of the mould to ensure the precision of the movement guide of the opening and closing die. There are two types of lead posts and shoulder posts. Push plate guide column: with the push plate guide sleeve (or hole) is a sliding fit, used for the movement of off - mold mechanism guide cylinder two. Guide sleeve: with the guide column installed on the other half of the mould, it is used to ensure the relative position of the moving die and the fixed die, and to ensure the precision of the movement guide of the die opening and closing die. There are two types of direct guide sleeve and lead guide sleeve. Push and pull guide sleeve: fixed on the push plate, which is in smooth cooperation with the push plate guide column, used for the circular sleeve of the movement guide of the demoulding mechanism. 3. Push out parts Push rod: the rod parts that directly push out the plastic parts or the casting system's coagulant are cylindrical head push rod, shoulder push rod and flat head push rod, etc. Cylinder head push rod can be used to push the top push - top plate, also known as pre - rod. Push pipe: directly push out the plastic parts of the tubular parts. Push plate: directly push out the plastic parts of the plate. Push ring: a ring or disc part that partially or wholly pushes out a plastic part. Push rod fixing plate: a plate type part that secures the ejection and resetting parts and the guide sleeve of the pushing plate. Push rod: supporting push - out and resetting parts, directly transfer machine tool push - out force of the plate. Connecting push rod: connecting push plate and push plate fixed plate, transmitting thrust bar. Pull rod: it is set directly opposite the main channel and has a special head shape, which can pull out the main channel coagulant. The head shape is Z shape, ball head shape, inverted cone shape, mushroom shape and cone head shape, etc. Push runner plate: as the open die movement, the casting system of the condenser plate parts. Also called thrust plate. 4. Core drawing (typing) parts Oblique pin (oblique guide column) : a cylindrical part that is tilted to the parting surface for assembly. With the opening and closing of the mold, the sliding block (or concave die block) generates reciprocating movement within the mold. Sliding block: moving along the guide structure, driving the side core (or concave die assembly) to complete the core pulling and resetting. Side core slide: side core or slide block made of integral material. Sometimes several sliders are formed into modules, which need to be separated first before the plastic parts can be removed smoothly. Slide guide plate: with the slide guide surface of the slide block to cooperate, play the role of slide guide plate. Wedge block: a part with a bevel Angle used to lock the slider when closing the die. Bend pin: a rectangular or square section bending part that allows the slider to act as a core pulling and resetting movement with the opening and closing of the mold. Slanting block: the concave die block that USES the combination of the inclined plane and the die sleeve to produce sliding, which has the function of forming, pushing and core pulling (parting). Inclined groove guide plate: a plate type part with a inclined guide groove, which makes the slider move with the core pulling and resetting of the groove along with the opening and closing of the mould. 5. Support fixed parts Positioning plate: the choice of fixing the fixing plate on the fixed working table of the injector. Moving die seat plate: a piece of plate that holds a moving die fixed to a moving table of an injector. Die plate: plate part of a fixed plate (cavity), also called a cavity plate. Core type fixing plate: plate type parts of fixed core. Die sleeve: a frame-sleeve structural part that allows the insert or assembly to be positioned and tightened together, or a frame-sleeve part that secures the die or core. Supporting plate: plate that prevents the axial displacement of forming parts (die, core or insert) and guiding parts, and bears the forming pressure.

Bracket: adjust the closing height of the mould, form the ejection stroke space required by the demoulding mechanism, and make the moving die fixed on the "L" block part of the injector, also known as the die foot. Supporting column: a columnar part set between a supporting plate of a moving die and a supporting plate of a moving die to enhance the rigidity of a supporting plate of a moving die. 6. Positioning and limiting parts Positioning ring: the circular ring or circular plate-shaped part that makes the main channel of the mold align with the nozzle of the injector and determines the position of the mold installation on the injector. Tapered positioning parts: when the die is closed, the corresponding matching taper surface is used to make the moving part and the fixed part accurately positioned. Resetting rod: a rod member fixed to a push rod fixing plate that resets the release mechanism by the closing action of the mould. Limit nail: the part that supports and adjusts the demoulding mechanism, prevents the demoulding mechanism from being affected by foreign matter obstacle in resetting, or restricts the bar piece of the final position after the core is removed from the sliding block. Pitch bar: a rod member used to restrict the pulling or stopping action of a template within a specified distance when the die is split. Locating pin: a cylindrical member that holds two or more templates in place to prevent displacement. Fixed - distance drawing board: a board member used to restrict the pulling or stopping of a template only within a limited distance when the die is split. 7. Cooling and heating parts Cooling nozzle: pipe fitting used to connect rubber pipe and pass cold water into the mould. Baffle: metal strip or plate set in the cooling water passage in the mould to change the direction of cooling water Heating plate: the plate with heating structure, such as hot water (oil), steam or electric heating element, is set to ensure that the mold temperature meets the requirements of plastic forming process.

We know that cars are made up of thousands of stampings during manufacturing.The stamping parts are made of various kinds of metal stamping parts, precision hardware fittings, electronic components and so on. The quality of the stamping parts is very important to the quality of the vehicle, especially for cars and buses.In the manufacture of stamping parts, enabling for large stamping parts with complex space geometry, interior parts, welding artisan run into, or for easy small stamping parts, such as interior parts, more use of professional with the testing jig (fixture) as a matter of detection means, for product quality control procedures.It has the advantages of rapid, accurate, intuitive and convenient, especially suitable for mass production.After the mid-1980s, with the rapid development of the automobile and bus industry, the application of stamping parts in China's automobile industry is quite common. Composition and characteristics of vehicle stamping parts inspection tools. Compared with the hardware processing parts, the detection of automobile stamping parts has the following characteristics: 1. The shape of the workpiece is often complicated and irregular, and it is difficult to locate, support and clamp. 2. The rigidity of the workpiece is generally poor, and it is easy to cause deviation in the detection process; 3. besides a few small stamping parts, usually put the size of the stamping benchmark in body coordinate system to deal with, in addition to many of the characteristics of workpiece parts (such as holes, flange, etc.) compared to the neighboring grid line to indicate on the diagram to the distance dimensions, for most of the contours of free-form surface (especially) did not give a size values.At present, the model of grid dimensioning with coordinate grid has been gradually replaced by CAD data.The CAD data supplied by the design department for stamping parts, welding parts and even the body can be used as the dimensional basis for making mold, welding fixture and fixture. It is believed that the production scale of various hardware processing components can also be guaranteed with the continuous expansion of various hardware processing companies.

1. the U.S. In recent years, the us manufacturing industry has fallen into recession, manufacturing industry has shifted to the world, and the development of mould manufacturing industry has also been affected.In 2006, the total revenue of the U.S. special tools, molds and fittings was about $8.29 billion, and the total profit was 24.88%, $2.06 billion.The total value of imports and exports was $1.43 billion, and the major trading countries were: Japan $460m (32.07%);Canada $460 million (32.06%);Germany $130 million (9.39%);Mexico $65 million (4.58%);China's $45 million (3.18%).In 2006, the total import value was $1.01 billion, and the major importers were: Japan's $430 million (42.19%).Canada $2.96 billion (29.18%);Germany $110 million (10.87%);South Korea $36 million;China $30 million (2.93%).In 2006, the total value of exports was $3.87 billion, and the major exporters were Canada $1.6 billion (41.39%).Mexico $62 million (15.99%);UK $25 million (6.46%);Germany $20 million (5.05%);Japan $15 million (3.96 percent).The die and mould industry in the aspect of nc machine tools are strong: because the first car, bearing production requirements, fully developed a large number of large quantities of automatic line for production automation, and electronic and computer technology in the world's leading, so the numerical control machine host a solid design, manufacturing and CNC system, and has always attached importance to scientific research and innovation, so the high performance CNC machine tool technology also has been leading in the world. 2. Germany Germany is one of the earliest engaged in mold manufacturing countries of Europe, after the second world war manufacturing industry has developed rapidly, make its mold manufacturing technique is becoming more and more excellent, more precision by global users affirmation, and enjoys a high reputation in the world, is one of the world's most important mold suppliers.According to the German machinery factory manufacturing association (VDMA) according to the mold factory quotient about 5000 or so, which belongs to the VDMA members mould enterprise with 90, this 90 mould enterprises output value accounted for 90% of German mold production, but the mold industrial structure still is given priority to with small and medium enterprises, manufacturers number of employees under 20 people accounted for eighty percent, the number of employees 20100 people by about 19%, the number of employees accounted for only 1% of over 100 people.According to the information released by ISTMA, Germany mould products generate accounted for about seven major European mould producer total products generate fifty percent, much higher than the second 2.2 billion euros in Italy, visible mold industry in Europe, Germany and even has a pivotal position in the world.Import and export countries, Germany imported mould main source of supply for Switzerland and the European Union countries, such as Italy, Switzerland, the Czech republic, countries such as France and Austria, which accounts for about one 5 of total but imports, Italy ranked first, also for rubber and plastic injection and compression molding and metal injection and compression molding the largest supplier of Swiss import share in time, for the maximum pressure, impact, collision play tool supplier. Germany's main export areas still is given priority to with Europe, Switzerland since 1997, is Germany's leading exporter, but with the downstream products manufacturing base gradually moved to the eastern European countries including the Czech republic, Poland, Hungary and other countries, causing a huge growth in recent years the proportion of exports to the Czech republic, it also highlighted the trend of global manufacturing shift to emerging industrial countries.In mainland China in recent years, as Germany's third-largest exporter, total exports accounted for about 8.0%, as to export to other Asian markets, such as Japan, South Korea and Taiwan) the proportion of the amount is minimal. The Germany still in Europe market, mold mold market also occupies an important position in the whole world, but in recent years by China and eastern Europe, such as the Czech republic, Hungary and other emerging new dig up a manufacturing base, facing the situation similar to another mold powers - Japan, originally rock-solid mold industry have loose phenomenon, associated with mold industry gradually moved to overseas factories in Germany. 3. Japan In 1945 just after the Anti-Japanese War, Japan did not die and mould industry has been as an industry, with the increase of trade liberalization and imports, the country's mold enterprise into a very difficult position, the Japanese government began to realize the mould is one of the important products, decided to Japanese enterprise international competitiveness requires preferential policy support, thus to develop and implement the mechanical industrial revitalization of temporary CuoShiFa "(hereinafter referred to as" the method of vibration machine "), enacted in 1956, in 1961 and 1966, respectively, to extend the 5 years, and unified in 1971 and 1971 after the relevant laws and regulations,Officially expired in 1985."Machine vibration method" in the "mold manufacturing rationalization basic plan" put forward an operation process, namely against rationalization basic calculation model, from the mold enterprise to miti supplies don't original equipment modernization plan is put forward, after review the Japanese special development bank financing.According to statistics, the implementation of the "machine vibration method" began 5 years, 294 companies received about 11.2 billion yen with 6.5 percent special interest.Direct effect is that the mold enterprise significant increase in the number of production equipment, such as the 1958 Japanese mold, a total of 1164 enterprises, the average company's production equipment is 14.9, while by 1964 that figure increased to 23.6.The indirect effect is that the process of obtaining financing approval is itself closely related to the change of the management system and the financial ability of the mold enterprises.With the implementation of the "method of vibration machine" as an opportunity to Japan will die and mould industry was founded in 1957, and all kinds of information collected through the association activities, mould enterprise at home and abroad to contact information, results are obvious.To sum up, the Japanese government is not limited to unilateral measures, but more focused on guiding enterprises to enhance their core competitiveness.In view of this, the Japanese mould industry has achieved rapid development. According to the 1994 statistics of the international die association, the Japanese mold production value accounted for 43.4% of the total annual output value of the world's mold. After the "plaza accord" in 1985, the appreciation of the Japanese yen had a great impact on the Japanese economy.Japan's manufacturing industry to transfer to southeast Asia in order to reduce costs, especially in 1993-1993, the fourth after the yen, Japan's small and medium-sized mould enterprise because of reduced orders, mould prices down, in deep crisis.From 1991 to 1991, suffer from Japan's domestic market demand as well as small and medium-sized enterprise operators absence or reason, Japan die mold manufacturer and employment decreased by 28% and 28% respectively in 15 years, mold production declines since 1997, the decline rate was 11%.For example, in 1998 Japan's mold output reached a peak of y18,70bn, and in 2006 it fell to y410bn.It can be concluded from the gross profit rate of the mold industry that the small and medium mold enterprises in Japan are undoubtedly affected by the industrial hollowing and the collapse of industrial clusters. As Japan's large manufacturing enterprises such as mitsubishi, sharp, Honda, Toyota and other overseas big transfer of industry, Japanese mold enterprise to survival and development to expand overseas markets, use set mold enterprise abroad;Or joint ventures with local enterprises;Or send to oneself familiar mold enterprise and so on.As a result, in the field of general mold technology, the tendency of mechanical machining technology to replace mold skill is presented.As a result, China, South Korea's mould with price advantage increased exports to Japan, technology content in the perfection of die mold marketing field has become more Japanese small and medium-sized enterprise's main rival.The increase of mold exports at the same time, along with Japan, the Japanese mold enterprise set up the maintenance station in southeast Asian countries and enterprises provide toward the industry transfer of mould drawings for mold in the process of the localization of form a complete set, also caused the loss of mould technology and even the loss of part of mold market. Because of this, Japanese mold companies have to focus on the production and technology upgrading of high-end moulds to avoid price competition.Namely, with small and exquisite, small and special technical accumulation as a source of competitiveness, prompting innovation needs of medium/small mould enterprises, build the sustainable development of environment, its characteristic is the flexible combination of correspondence and professional, with skilled people as main body, the advanced equipment and processing technology and integrating the traditional processing technology, and many varieties, small batch production mode is used to improve competitiveness. 4. Italy Italian plastic rubber processing machinery and mould manufacturing industry is the Italian machinery manufacturing alliance one of ten special machinery manufacturing industry, has more than 500 patents of Europe, high degree of specialization, leading technology, product variety.Its output value accounted for 16.5% of the total output value of the ten industries of the machinery manufacturing union, 20% of the domestic market consumption, 13.8%, 15% and 13.4% of the trade balance respectively. According to the Italian plastic rubber processing machinery and mould manufacturing industry association (ASSOCOMAPLAST), according to 2006 Italian plastic rubber processing machinery and mould manufacturing to achieve output value of 3.8 billion euros, spent 2.171 billion euros in the domestic market, export 2.268 billion euros, imported 589 million euros.In 2006, the trade surplus was 167.9 billion euros. 5. Portugal The development of mold industry in Portugal started in 1943 and is leading in injection molding industry.By 1980, the mold products had been sold to more than 50 countries. At that time, there were 54 mould companies in the city of marinia grant, with 2,000 employees. Currently, there are 300 enterprises in the mold industry, mainly small and medium-sized enterprises, most of which are located in the two cities of marinea grant and oliveira DE azemeesi, with a total employment of 7,500 people.Including Ma Li Virginia grant city has 190 mould enterprises (accounted for 63% of the national mold enterprise), employees 5000 people, oliveira jersey Michael o DE yi city has 86 mould enterprises (accounted for 29% of the national mold enterprise), employs 1600 people. After more than half a century of development, the Portuguese mould enterprises have summarized and accumulated a lot of technical experience.Is generally believed that the Portuguese mold and die industry mainly depends on the improvement of the overall level of technology development, the reasonable production and quality control plan, constantly updated equipment, and strengthen professional investment and other factors.At present, in line with the management concept of process competition and overall quality, the company is the first to use high precision CNC equipment, and generally use CAD/CAM/CAE system in the process of mold design.Portuguese mold enterprise profits directly reinvested average proportion is as high as 18%, including the United States, Britain, South Korea, Japan and France, the international association of mold industry and special tools (ISTMA) members are in first place.With the development of technology and perfected, the Portuguese mold enterprise specialization degree unceasing enhancement, many enterprises have gradually to the mold, polishing, large mould or specific fields, such as high precision mould development.

The injection mold has six major systems, and the guiding system is to ensure that the dynamic and fixed modes can be set accurately in the mold, and the guide parts must be set in the mold.In the injection mold, four sets of guideposts and guide sleeve are usually used to form the guide parts. In some cases, the inner and outer cone of each other can be set up to assist the positioning. The guide pillar plays a leading role in the mould, so as to ensure that the forming surface of the core and cavity is not mutually touching in any case, and the guide column can not be used as the force part or positioning piece.What about the damage of the guide post in the process of using the injection mold to process the parts?According to changsha borun, it is necessary to work hard to solve the problem of the guide column injury, and it is necessary to work on the design of the injection mold to achieve a lasting effect. The injection mold factory should make a set of high quality injection mold to understand each mold design, manufacturing, molding every detail, understand the use of each part in the mold.Clear guide pillar play a major role in injection mold, understand the harm done by the guide pillar damage on the moulds, will be better in the subsequent use of attention to this kind of problem, not only can produce good plastic products better, also greatly improve the service life of the injection mould. In the design of the guide column, it is necessary to consider the problem of the blade. Otherwise, the guide column can be turned into a positioning mechanism, and the guide sleeve needs to have a vent hole, which prevents the forming of vacuum mold after the closing of the mold, which produces a great suction force. In the following situations, the injection process of the core cavity can produce a large four direction of the centripetal force.When the wall thickness of the plastic part is not uniform enough, the plastic flow will increase through the thickness of the wall, and it will generate a large injection pressure here.The lateral asymmetry of the plastic parts, such as the plastic mold of the step parting, is different from the pressure on the ladder, so the width of the parting surface should be considered in the design of the mold. Dynamic plate bending When the mold is injected, the molten plastic in the mold cavity generates a huge reverse pressure, usually between 600 and 1000 kg/cm.Mold makers sometimes don't attach importance to this problem, often change the original design size, or replace with low strength steel plate, the dynamic template in the mould of material with a plunger, because on both sides of the large span, cause the injection template under bending.Dynamic template must choose high quality steel, must have the enough thickness, must not use # 45 steel such as low intensity, when necessary, or support block should be set at the bottom of the dynamic template shores, to reduce the thickness of the template, improve the bearing capacity.

With the development of the market and the increase of demand, the demand for products is getting higher and higher, which is nothing but a good challenge for the mold accessory maker, changsha borun.At present, the variety of mold parts manufacturers and parts more and more, factory production of mold parts can meet the needs of the market is that we need to confront and question.So, what are the standard requirements for the processing of high precision parts in the mold parts factory? 1. Cold and thermal fatigue performance of parts. Some mold in the process of work is in a state of repeated heating and cooling, the cavity surface tension, pressure and stress effect, cause surface cracking and spalling, increase the friction, obstacles to plastic deformation, reduces the dimension precision, resulting in the mould failure.Cold and heat fatigue is one of the main forms of thermal die failure. It should have high resistance to cold and heat fatigue. 2. Strong and resilient parts. The working conditions of precision mould parts are very bad, some of them are often subjected to a large impact load, which leads to brittle fracture.In order to prevent the mold parts from breaking suddenly at work, the mold should have high strength and toughness.The toughness of the material depends on the carbon content, grain size and organization state of the material. 3. High temperature performance of parts. When the working temperature of the mold is high, the hardness and strength will be reduced, which will cause the die to wear out or to produce plastic deformation.Therefore, the mould material should have high tempering stability to ensure that the mould has higher hardness and strength at working temperature. 4. Corrosion resistance of parts. Some mould such as plastic die on the job, as a result of the elements such as chlorine, fluorine plastics, thermal decomposition after precipitation HCI, HF, such as strong erosion gas, erosion surface of mould cavity, increasing its surface roughness, aggravate the wear failure. 5. Fatigue fracture performance of parts. In the working process of precision mold parts, fatigue fracture is often caused by the long-term effect of cyclic stress.Its form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture.The fatigue fracture performance of the die depends on its strength, toughness, hardness and inclusions in the material. Above 5 points is mould factory in the processing of high precision components, shall meet the standards and requirements, based on the above points, changsha borun embellish think, only in product innovation, high standard, strict, can better meet the demand of future mold accessories market. NITONI, As a China Precision Mold parts, Core pin, Ejector pin, Mold punch, Mold parts, Mold components, Non-standard Precision Parts, plastic mold parts, press die mold parts, manufactur and supplier,At present, The mould accessories products are mainly divided into Non-standard mold parts, Plastic mould parts, Press die mold parts, Die Springs, welcome to understand the customization.

With the increasing production demand of enterprises, most manufacturers pay more and more attention to the characteristics and performance of products, and some enterprises' products have become more and more customized and developed.So now that is the custom, of course, inseparable from the non-standard customized professional equipment, and in this kind of custom equipment in use process, non-standard mold parts plays a key role, inappropriate if non-standard mold parts of choose and buy will lead to the size of the product, quality closes nevertheless, so that enterprises in the purchase of non-standard mold parts need to pay attention to the following these things. 1. Pay attention to the dimensions of mold parts. Due to the non-standard equipment are custom made according to the enterprise's demand, so some of the mold and its accessories are also not production according to international standards, but according to the specific requirements of non-standard equipment and products to manufacture, so enterprise want to purchase the good quality of non-standard mold parts, first of all need to be aware of is the size of the die parts to consistent and non-standard equipment, can be installed to the device in use. 2. Pay attention to the precision of mold parts. As the saying goes, "the big difference., accuracy is a very key factor, the enterprise in order to be able to ensure that produce products that meet the requirements, in the purchase of non-standard mold parts when we must pay attention to calculate good accessories required accuracy, and then to select the most matching based on precision non-standard mold parts to use. 3. Pay attention to the material of mold parts. Mold and its accessories in the process of long-term use, although can produce loss, but it is not the consumption of disposable items, in order to reduce the attrition rate of mold parts, prolong the service life of parts, enterprises purchase non-standard mold parts when they need to pay attention to understand what the material is used, on the one hand, want to know whether the durability is strong, on the other hand to understand whether suitable for enterprise produced products. For enterprises, the purpose of using non-standard equipment is to be able to produce the most satisfactory products, and can be in one respect to those of other competing goods, but to do this, you need to use high quality non-standard mold parts, so, mould non-standard accessories manufacturers, changsha, borun think, before purchasing understand non-standard mold parts which brand is good, the choose and buy good brand of die parts will be more secure in terms of quality. NITONI, As a China Precision Mold parts, Core pin, Ejector pin, Mold punch, Mold parts, Mold components, Non-standard Precision Parts, plastic mold parts, press die mold parts, manufactur and supplier,At present, The mould accessories products are mainly divided into Non-standard mold parts, Plastic mould parts, Press die mold parts, Die Springs, welcome to understand the customization.

There are more than 10,000 precision parts of a car, and its parts are divided into two parts: frame, exterior plate, chassis, engine, interior, glass, tyre, etc.Every parts by different process molding, to assemble in the car, mold accessories manufacturers today changsha borun embellish together with you to get to know the car parts processing 7 big craft. 1. casting Casting is the casting of molten metal into the cast cavity, cooling solidification and obtaining the production method. In the process of automobile manufacture, there are a lot of parts is made of cast iron blank which accounts for about 10% of whole vehicle weight around, such as cylinder block, transmission box, steering gear housing, rear axle shell, brake drum, all kinds of stents, etc. Cast iron is usually made of sand.The sand - type material is mainly sand, and is mixed with binder, water and so on.The sand type material must have a certain adhesive strength, so that it can be molded into the desired shape and can resist the hot iron water erosion without collapse.In order to shape the cavity in the sand mold to fit the casting shape, the model must be made of wood, which is called wood mould.The size of the hot molten iron will be reduced after cooling. Therefore, the size of the wood mould needs to be enlarged on the basis of the original size of the casting, and the surface of the cutting process needs to be thickened accordingly. Hollow castings need to be made of sand cores and corresponding cores (core boxes).With the wood mold, you can turn the cavity sand mold (casting is also known as "turning sand").When making sand, consider how to separate the upper and lower sand boxes to remove the wood mold, and consider where the molten iron is flowing in, and how to fill the cavity to get high-quality castings.After the sand mold is made, it can be poured, which is to pour molten iron into the sand type cavity.When pouring, the iron water temperature is 1250-1350 degrees, and the temperature is higher when smelting. 2. forging The forging process is widely used in automobile manufacturing.Forging is divided into free forging and model forging.Free forging is the process of forming a metal blank on an anvil to withstand shock or pressure.The blank of the gears and shafts of a car is processed by means of free forging. Model forging is the process of forming the metal billet in the mold chamber of the forging die, bearing the impact or pressure.Model forging is a bit like the process of the dough being pressed into the shape of a cookie in the mold.Compared with free forging, the workpiece produced by die forging is more complex and more accurate.Typical examples of automobile die forging are: engine connecting rod and crankshaft, automobile front axle, steering knuckle, etc. 3. Cold stamping Cold stamping or sheet metal stamping is the process of cutting off or forming the metal sheet under pressure in the die. Daily necessities, such as aluminum pot, lunch box, washbasin and so on are made by cold pressing processing method.Making lunch box, for example, you first need to cut out a rectangle with four rounded corners of billet (expert, called "blanking"), then the billet with a punch press into the die and forming (expert called the "drawing").In the deep drawing process, the sheet of the plane is turned into a box, and its 4 edges are curved upward, and the materials on the four corners are piled up and the wrinkles are visible. The parts with cold stamping are: engine oil sump, brake floor, car frame and most body parts.These parts are usually made by blanking, punching, drawing, bending, turning, trimming and so on.In order to make cold stamping parts, the stamping die must be prepared.The die is usually divided into two pieces, one of which is mounted on top of the press and can slide up and down, while the other is mounted under the pressing bed and fixed.During the production, the blank is placed between two punch dies. When the upper and lower mold is closed, the stamping process is completed.Stamping processing is highly productive and can produce parts with complex shapes and high precision. 4. welding Welding is the process of heating or pressing the two pieces of metal together. We common workers in one hand and a mask, and the other in one hand and the wire connected to the electrode holder and electrode welding method called manual electric arc welding, which is generated by arc discharge of high temperature melting welding rod and welding pieces, joint. Manual arc welding is not widely used in automobile manufacturing.The most widely used in automobile body manufacture is spot welding.Spot welding is suitable for welding of thin steel plate, when operating, add 2 to 2 steel plate electrode pressure to stick a merger and joint point (5-6 diameter circular) electricity melt flow heating and strong joint.When two body parts are welded, the edges are welded to one point every 50 to 100 pieces, making the two parts to form discontinuous multi-point connections.Welding the entire car body usually requires a thousand solders.The strength of solder joints is very high, and each solder can withstand 5kN tension, even tearing the steel plate, still can not separate the solder site. Common gas welding in the repair shop is made of acetylene burning with oxygen to produce a high temperature flame, which melts the electrode and the welding parts.You can also use this high temperature flame to cut the metal, which is called gas cutting.The application of gas welding and gas cutting is more flexible, but the thermal influence zone of gas welding is larger, which causes the deformation of welding parts and the change of metallographic structure.Therefore, gas welding is seldom used in automobile manufacturing. 5. About metal cutting. Metal cutting is used to cut the metal blank layer by layer.The workpiece is machined for the desired shape, size and surface roughness.Metal cutting includes two methods: fitter and machining. The fitter is a method of machining by hand tools, which is flexible and easy to operate and widely used in assembly and repair.Machining is done by means of machine tools, including: car, plane, milling, drilling and grinding. 1). turning Turning is the process of machining workpiece on lathe.The lathe is suitable for cutting various rotating surfaces, such as inner, outer cylinder or conical surface, and can also be used for turning the end face.Many of the shaft parts of the car and the gear blank are machined on the lathe. 2). planing Planing is the process of machining the workpiece with a planer.Planer is suitable for machining horizontal plane, vertical plane, inclined plane and groove etc.The cylinder block and cylinder head of the car are processed by planer, with the surface of the cylinder, the box body of the transmission and the plane of the cover. 3), milling Milling is the process of milling the workpiece on the milling machine.Milling machines can be used to process all kinds of automobile parts, such as inclined plane, groove, and even old milling machine, such as gears and curved surfaces.Automobile body cold stamping die is used for milling.CNC milling machine can be machined with complex shape and is the main machine tool for modern machining. 4). drilling and boring. Drilling and boring are the main cutting methods for machining holes. 5). grinding Grinding is the process of grinding the workpiece with grinding wheel on the grinder.Grinding is a kind of finishing method, which can obtain high precision and roughness workpiece, and can grind the workpiece with high hardness.Some of the car parts after heat treatment are processed with grinding machines. 6. Heat treatment Heat treatment is to reheat, heat or cool solid steel to change its organizational structure to meet the use requirements or process requirements of the parts.The temperature of the heating, the length of the heat preservation time and the speed of the cooling speed can make the steel produce different tissue changes.The blacksmith immerses the heated steel in the water for rapid cooling (known as quenching), which increases the hardness of the steel, which is an example of heat treatment. The heat treatment process includes annealing, normalizing, quenching and tempering.Annealing is to heat the steel parts and keep them warm for a certain period of time. Then, with the furnace, it will slowly cool down to obtain a finer and even structure and reduce the hardness to facilitate the cutting process. The normalizing is to heat the steel parts, remove them from the furnace, and then cool them in the air, which is suitable for refining the low carbon steel.Quenching is to heat the steel, heat it in the water or quickly cool it in the oil to improve the hardness. Tempering is usually the following process of quenching, reheating steel parts after quenching, cooling after heat preservation, stabilizing the tissue and eliminating brittleness. There are a lot of auto parts, which should not only retain the toughness of the heart, but also change the surface structure to improve the hardness, so it is necessary to adopt the heat treatment technology such as high frequency quenching or carburizing and cyanidation. 7. assembly Assembly is according to certain requirements, with connection parts (bolts, nuts, pins, or card buckle, etc.) the mutual connection and combination of all kinds of accessories into parts, and the various components are connected and assembled into the vehicle. Whether the parts are assembled into parts or assembled into a vehicle, they must meet the requirements of the design drawing to meet the required performance of the parts or vehicles.For example, when the transmission is assembled to the clutch housing, the center line of the transmission input shaft must be aligned with the center line of the engine crankshaft.This approach to the centre is not regulated by assembly workers (fitters) but by design and fabrication. If you visit a car factory, the most popular is the general assembly line.On this general assembly line, every few minutes, we drive off a car.Take the automobile general assembly line of China faw as an example.This assembly line is a 165 m long transmission chain, cars as transport chain moving to each workstation and gradually put into, around the engine and transmission of catenary assembly, cab assembly, wheel assembly continuously from the workshop to the corresponding location on the assembly line. In transmission chain of the starting position of the frame (bottom) is put first, and then driving axle assembly (including leaf spring and wheel) and front axle assembly (including leaf spring, steering knuckle, and hub) installed on the frame, and then install the frame to turn it over to steering gear, air storage tank, and the brake pipe, tank and oil pipe, electrical, and wheels, and the final installation engine assembly (including the clutch, transmission, and the central brake), connected to the shaft, then install the cockpit and the front panel parts, etc.At this point, the car can drive off the assembly line.

Tecnun is a formula racing team from the university of navarra in Spain, who is responsible for the design and manufacture of students' racing cars for international formula competitions.Usually, it will take at least three weeks for the aluminum molds produced for the car parts to be used in the traditional way. What secret weapon will the team use?The team began to contact the new technology, 3 d printing, due to the limitation of strict production plan and budget, has been testing a variety of other as in the past Tecnun faster and cheaper alternative to the increase of material manufacturing technology, to expect can manufacturing tools.However, it was found that the plastic was not strong enough to break during construction. After try, Tecnun team finally found the right choice - using Stratasys material manufacturing technology, the team can be in a few hours, to produce the key components of the car very complicated 3 d printing mold.Importantly, use the time saved in the process of production, the team can to further update the design iterations, and developed the 60% lighter than the traditional production methods of the final carbon fiber parts, thereby increasing the performance on the track.The key to success, says Javier Aperribay, technical director of Tecnun Motorsport, is the design of the intake manifold, which ensures that enough air reaches the engine cylinder and is a key part of the speed increase.Aperribay explained: "because of the intake manifold is composed of some important parts, these parts for the four is very important for the air distribution along the intake manifold, thus making intake manifold is extremely complex, our goal is to manufacture intake manifold in the carbon fiber composite materials, but we are very clear, making these parts need to mould building composite material, and make the final parts.Computer numerical control processing is used in the production of aluminum mould, but this is usually not a flexible and costly process, in addition, any subsequent design of the mould modification will delay the project, and additional costs."By using the Stratasys Fortus 450mc printer and st-130 materials, Tecnun has successfully produced moulds such as intake manifold. Compared with aluminum molds, st-130 has superior solubility characteristics, making the shape of intake manifold more complex, so that all individual components are not assembled.Now the team can complete the production of the intake manifold 3D printing mold within 5 hours.With the increase of material before polymer materials is different, the material can be running under the high temperature of 121 ° C, and in the process of testing mold will not break, which help to achieve the best combustion reaction, improve track performance.

Often receives the client to ask about the question about the flat thimble: "how is your home flat thimble?"", "not durable?"", "high temperature resistance?"And so on...In fact, changsha borun small editor wants to say, the flat thimble that buy is not wear-resisting, also be not heat-resistant, easy to turn in the use process!To a large extent, it depends on the processing manufacturer and manufacturer of the flat thimble. Flat thimble is one of commonly used parts in plastic mould parts, flat thimble, also called the flat pin, push rod, ejector pin, needle, needle, etc., mainly used for plastic product ejection rod parts, and is the glue, elongated circle plunger cannot put down, we choose to use flat thimble.So, how to ensure the wear-resisting property of the flat thimble, this needs to be in the material of the flat thimble to choose up and down. Mold fittings factory changsha borun embellish sort out our several kinds of commonly used material when processing flat thimble, and their advantages and disadvantages, really solve for you in the purchase mould thimble products do not know how to choose the material of trouble. 1. SKD61 material. (it is divided into three categories: domestic SKD61, Taiwan nitride SKD61, Japanese vacuum nitride SKD61).Most customers will choose this material now, because of SKD61 material, has the high hardness and wear resistance after heat treatment, and have strong hardenability, good high temperature resistance, good dimensional stability characteristics, the commonly used material and mould thimble. 2. SKH51 material. High speed steel material, usually at the top of the client to aimed at the requirement of hardness, SKD61 difficult to meet, will choose SKH51 material, SKH51 material in addition to having the advantages of SKD61, also has the red hardness of SKD61 have no.Although SKH51 thimble material is better, but because of high speed steel material's price is more expensive, and SKD61 material generally can meet the requirements of most mould thimble, so SKH51 thimble and less common than SKD61 thimble used. 3. Material of 65Mn The reason behind this material is that the material is cheap and has a price advantage, but the quality of the thimp is far from the SKD61 material and SKH51 material.Now there are a lot of cheap thimbles in the market are this kind of material, the customer after buying use, will often happen to bend, break the situation. The above is about flat thimble processing several common materials, hope will be helpful to you.If you need to buy the flat thimp and mold non-standard parts, please contact NITONI changsha bogrun, we will process the quality mold parts products strictly according to your drawing specifications and material requirements.Looking forward to cooperating with you!

Flat thimble is one of commonly used parts in plastic mould parts, flat thimble, also called the flat pin, push rod, ejector pin, needle, needle, etc., mainly used for plastic product ejection rod parts, and is the glue, elongated circle plunger cannot put down, we choose to use flat thimble.So, how to ensure the wear-resisting property of the flat thimble, this needs to be in the material of the flat thimble to choose up and down. The flat thimble is the same as the thimble, but it is more stringent for the material requirement, because the processing position of the die flat thimble is thinner than the thimble. Flat thimble used is one of the most common material SKD61, because in plastic moulds, flat thimble processing environment temperature is higher, need heat resistant material, and SKD61 material can bear the high temperature of 1600 ° C, suitable for the use of flat thimble.When the hardness of SKD61 flat thimble is not enough, we can also make the surface nitride treatment to improve the wear resistance of the flat thimble.If SKD61 flat thimbus can not meet the requirements, it can also choose the skh-51 high speed steel flat thimmer, which is better than SKD61 in high temperature and wear resistance, and of course the price is more expensive. Plastic mould flat thimble despite part is standard parts, but most of the time are standard parts, mold parts manufacturers changsha borun embellish is commonly according to figure processing, material and size specifications and precision are processed according to customer requirements.

As is known to all, nitrogen springs can be placed in various forms in the mold.However, no matter which one we adopt, we must ensure that the nitrogen spring work is stable, reliable, installation, adjustment and maintenance as convenient as possible.In the fine blanking process needs a certain pressure to the ring gear, for separation of the parts are in compressive stress state, to obtain smooth section, it also requires nitrogen can exert strong pressure, to meet the requirements of the process.Ever on the single power presses to achieve fine blanking process, often adopts hydraulic equipment to produce power, likewise, in the fine blanking die used in the nitrogen gas spring, can not use a dedicated fine blanking press, in a single action press can be very convenient to obtain the desired tooth circle pressure, to ensure the quality of fine blanking parts.The nitrogen spring structure is relatively simple, the cost is low, and the adjustable pressure range is greater. Some designers will also nitrogen spring chamber design on the mold base guide post goods, so that you can follow up at any time need to adjust the pressure of the nitrogen gas spring, which is the pressure of the fine blanking gear ring, the relatively compact structure, which can effectively ensure the high quality of fine blanking parts, and it can be said to be the important trend of the development of fine blanking die today. Knowledge universal nitrogen spring placement: nitrogen springs can be placed on the upper or lower mold of the mold, the dynamic die or die, can be placed in the nitrogen spring, can also be inverted;The nitrogen spring is used inside the mold, which is called built-in and is used outside the mold.Nitrogen spring cylinder body at the bottom, plunger in the upper part, is called positive;In the upper part of the cylinder, the plunger is placed in the lower part, which is called inversion.

Metal stamping mould in use process need to timely maintenance to prolong its service life, in the process of metal stamping mold maintenance, with a focus on the metal stamping die structure within the inspection and maintenance of various spare parts, mould partsmanufacturer of changsha borun embellish that should pay attention to the following items: 1. After the mold is used for a long time, the cutting edge must be grinded, and the cutting edge surface must be demagnetized, which cannot be magnetized, otherwise it will be easily blocked. 2. In the process of mold use, the punch is prone to break, bend and bite, and the punching bag is generally chewed.The damage of punch and washers is usually replaced by parts with the same specification.The parameters of the punch are mainly working part size, installation part size, length dimension and so on. 3. Spring and other elastic precision stamping parts are most liable to damage in the process of use, and usually fracture and deformation occur.To take is to change, it is important to note that in the process of change of the specifications of the spring and models, the specifications of the spring and model identified by color, diameter and length of the three, only under the condition of the three are the same can be replaced. 4. Pressure material parts such as pressing plate, excellent glue, etc., unloading parts such as stripper plate, pneumatic top material, etc.Check the parts and parts of the parts and whether there is any damage, repair the damaged parts, check for air leakage, and take measures for the specific situation.If the windpipe is damaged, replace it. 5. Tighten the parts and check whether the fastening parts are loose or damaged. The method is to find the parts with the same specifications for replacement.

Double color mould is becoming more and more popular on the market at present, this technology can make the product more beautiful appearance, easy to change color and can not spray, double color mould is two kinds of plastic material in the same injection molding machine injection molding, two forming, but the product of a mold, the mold only to extend the service life of mould, need preventive maintenance, mold accessories manufacturers changsha borun embellish is recommended to do so: 1. Do not "clean" the hot tip of the gate Not to destroy the hot mouth, please before taking action, confirm the mouth type of hot runner system, and ensure that all operators are trained, can identify themselves are exposed to different types of tongue. 2. Check whether there is any early warning signs of rust or moisture in the loose hole If rust or moisture is found near the vent hole, it means that the internal condensation, or the water pipe, may break. 3. The resistance value of the interaction check heater Should start to use the heater, measuring its electrical resistance, if there is a plus or minus 10% of the floating resistance, can consider to replace the heater, in order to make sure it won't be in the production process of failure at the critical moment. Check the water flow. Connect a hose at the exit of the waterway to allow water to be left in the bucket through a hose.If the water is not clear or colored, there may be a rusting phenomenon, and a lack of flow means a blockage.If these problems are found, all water pipes will be drilled again to ensure smooth flow. 5. Check whether there is any sign of wear between the guide column and the guide suite If the trace is just present, you can extend its life by adding lubricant to the guide column and guide sleeve.If the wear is serious, we should replace the new parts.
