Mold production process level and the level of scientific and technological content, has become a measure of a national science and technology and product manufacturing level of the important symbol, it largely determines the product quality, efficiency, new product development capabilities, determines a national manufacturing The international competitiveness of the industry. According to the development of domestic and international mold market situation, the experts predict that the future of China's mold industry after the structural adjustment, the accuracy of the mold will be higher and higher.
Mold is the basis of industrial production technology and equipment, in electronics, automobiles, electrical, electrical, instrumentation, home appliances and communications products, 60% to 80% of the parts are relying on mold forming, mold shape determines the shape of these products, Die processing quality and accuracy will determine the quality of these products. I produced the LCD frame and other products, the material thickness is usually around 0.2mm, are ultra-thin series of precision metal products, product flatness control in the 0.1 ~ 0.4mm or so, the key size tolerance ± 0.05, Phi Feng requirements in the 0.02 ~ 0.05 mm below, which requires my company to create the mold accuracy must be ± 0.02mm.
Summary
This paper analyzes the concept of mold precision, from the mold processing equipment, spare parts procurement, mold gap size, mold structure requirements, assembly technical requirements and mold manufacturing, management, testing and other aspects of the impact of factors on how to ensure mold accuracy, and put forward mold accuracy Requirements of the technical parameters for the mold manufacturing enterprises to provide precision molds industry standards.
The concept of mold precision
1. Mold is used as batch forming processing stamping and other products of precision forming tools. The precision of the mold includes the accuracy of the parts obtained during machining and the quality of the product to ensure the accuracy of the product. However, the precision of the mold is usually referred to mainly as the precision of the mold working parts.
①. The precision concept in mold processing refers to the degree that the actual geometric parameters and the geometrical parameters of the mold parts are processed and assembled.
②. The precision concept in mold production refers to a kind of thinking mode which is gradually formed in the production practice of the enterprise workers, which guides the production behavior of the workers, a kind of quality consciousness, that is, the quality of the product precision is always carried out in the behavior of the employees awareness.
2. Mold precision content includes four aspects: dimensional accuracy, shape accuracy, position accuracy, surface accuracy. As the mold in the working hours on the mold, the mold part of the two, so in the four precision above and below the mold position accuracy between the most important.
3. Mold accuracy is to serve the accuracy of products, high-precision products must be more accurate mold to ensure that the mold accuracy is generally higher than the accuracy of two or more level.
