We all know that the components with mold forming technology have certain adaptability. It requires relatively thin parts and certain molding. It is difficult to use die stamping for components with thickness and diameter such as crankshaft and connecting rod. At present, the most can be used is to make the rough die of crankshaft first, and then use cutting to finish machining.
The advantage of using mold is that it can reduce cost, save time, improve production efficiency, so that enterprises can be invincible in the fierce competition. However, at present, the mold used in automobile manufacturing, or plastic components, lights, steel shell and other accessories. The real automobile core engine still uses cutting technology, not mold technology.
In addition to the engine can not use mold technology, the crankshaft used in the car can not use this technology. Why?
The technological level and scientific and technological content of mould production has become an important mark to weigh the level of science and technology and product manufacturing in a country. To a great extent, it determines the quality, efficiency, development ability of new products and the international competitiveness of a country’s manufacturing industry. According to the development of domestic and international mold market, mold expert Luo Baihui speculates that the mold precision will be higher and higher after the industry structure adjustment in China in the future. Die is the basic process equipment of industrial production. In the products of electronics, automobiles, motors, electrical appliances, meters, household appliances and communication, 80% – 90% of the parts and components are formed by the mold. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products.
With the improvement of economy and living standard, the number of cars is also rising. When we see so many cars, we can’t help but realize the huge production behind the manufacturers. Undoubtedly, China’s die and mold industry has led the development of the automobile industry. What is the impact of mold on automobile manufacturing and what requirements does the automobile manufacturing industry have on the mold industry.

With the increasing of economy and survival, the number of cars is also rising. When we see so many cars, we can’t help but realize the huge production behind the scenes of the manufacturers. Undoubtedly, China’s mold industry has led the development of automobile industry. What kind of influence does the mold have on automobile production and what requests does the automobile manufacturing industry have for the mold industry.
The advantage of using mould is to reduce cost, save time, raise production efficiency, so that enterprises can be invincible in today’s fierce competition. However, the mold is now used in automobile production, or plastic components, lights, steel shell and other accessories. The real automobile heart mobilization machine still adopts cutting skills, never adopts mold skills.
Unless the mobilization machine can not adopt the mold technology, the crankshaft used in the automobile can not adopt this technology. Why? We all know that the components that adopt the molding techniques have certain habits. They require thin measurement and definite molding. For components with thickness and diameter, such as crankshaft and connecting rod, it is difficult to measure with die stamping. At present, the best way to adopt is to use die to make crankshaft rough embryo, and then to adopt cutting for finish machining.
When the machining precision is very high, the mold is often surplus but not enough force. The precision of today’s fine and fine molds is roughly in the range of 0.1-0.01 mm. Compared with the previous molds, the accuracy has been greatly increased. However, components like mobilizers require accuracy below one thousandth of a millimeter or less. Nowadays, it is not suitable to use the mould for machining.
Mold today’s own smoothness, roughness once had a great leap. However, the mold itself is also made by machine tools. If the accuracy of the machine tool used to make the mold itself cannot pass the standard, the precision of the products produced is bound to be low. Therefore, mold experts believe that the adoption of excellent mold skills is the inevitable trend of fierce competition, and it is more important to raise the mold’s personal competitiveness to get used to the market. It is the request of mold industry development and the heart of automobile and other industries to raise the high precision of mold.
Strengthen the recognition of die precision concept
1。 Die is a kind of fine forming tool used for batch forming, stamping and other products. Mold precision includes the accuracy of parts obtained in processing and the quality awareness of ensuring product precision when producing. But the mold precision usually refers to the precision of professional parts of mold.
①。 The concept of precision in mold processing refers to the actual geometric parameters after the mold parts are processed and assembled
