The level of craftsmanship and technological content of mold production has become an important indicator for weighing a country’s technology and product manufacturing level. It determines the quality, efficiency, and development strength of new products to a large extent, and determines the production of a country. international competitiveness of the industry. According to the development of the domestic and international mold market, mold experts speculate that in the future, after my country’s molds are adjusted by the industry structure, the accuracy of the molds will become higher and higher. Molds are the basic process equipment for industrial production. In electronics, automobiles, motors, electrical appliances, instruments, home appliances and communications, 80% to 90% of the components are formed by molds. The shape of the mold determines the appearance of these products. The processing quality and precision of the mold also determine the quality of these products.
With the increasing economic and survival level, the number of cars has also increased. 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 the automobile industry, so what impact does the mold industry have on automobile manufacturing, and what requirements does the automobile manufacturing industry have for the mold industry?
The advantage of using molds is that it can reduce costs, save time, improve production efficiency, and enable enterprises to remain invincible in today’s fierce competition. However, now the molds used in automobile production are still plastic components, lights, steel shells and other accessories. The real car heart engine still uses cutting technology, not mold technology.
Unless the engine cannot adopt the mold technology, the crankshaft used in the automobile cannot adopt this technology. What’s the reason? We all know that the components that use the mold forming technology have certain habits, which themselves require thinness and certain molding. For components with thickness and diameter like crankshafts and connecting rods, it is still difficult to use die stamping. At present, the most acceptable method is to first use the mold to make the crankshaft blank, and then use cutting for finishing.
When the machining accuracy requirements are very high, the mold is often overwhelmed. The accuracy that can be achieved by today’s very fine and fine molds is roughly in the range of 0.1 to 0.01 mm. Compared with the previous molds, the accuracy has been a big step up. However, components such as locomotives require an accuracy of less than a thousandth of a millimeter, or even smaller. Therefore, it is still not possible to completely replace the cutting process with a mold.
The smoothness and roughness of the mold today have made a great leap. However, the mold itself is also produced by the machine tool. If the precision of the machine tool that makes the mold itself cannot pass the test, the precision of the produced product is bound to be low. Therefore, mold experts feel that the adoption of excellent mold technology is an inevitable trend in the current habit of fierce competition, and the need to improve the competitiveness of molds to adapt to the market is the most important thing. The actual improvement of the high precision of the mold is the requirement of the development of the mold industry, and it is also the heart of the automobile and other industries.
Strengthen the recognition of mold precision concept
1. Die refers to a fine forming tool used for batch forming and processing stamping and other products. Mold accuracy includes the accuracy of parts obtained during processing and the quality awareness to ensure product accuracy during production, but the mold accuracy usually referred to mainly refers to the accuracy of mold professional parts.
①. The concept of precision in mold processing refers to the appropriate level of realistic geometric parameters and design geometric parameters after mold parts are processed and assembled.
②. The concept of precision in mold production refers to the various forms of thinking that are gradually formed by the employees of the enterprise in the production practice and lead the production actions of the employees, a quality awareness, that is, the quality awareness of mastering the accuracy of the product has been implemented in the actions of the employees of the enterprise.
