Mold experts believe that the use of advanced mold technology is an inevitable trend to adapt to the current fierce competition. It is even more important to improve the competitiveness of the mold itself to meet the needs of the market.
Effectively improving the precision of the mold is a requirement for the development of the mold industry, as well as the aspirations of the Automotive mould and other industries.
Strengthen the concept of mold accuracy:
1. A mold is a precision forming tool used for batch forming and stamping products. The precision of the mold includes the precision of the parts obtained during processing and the quality awareness of ensuring the accuracy of the product during production. However, the precision of the mold generally refers to the precision of the working parts of the mold.
①. The concept of precision in mold processing refers to the degree of conformity between the actual geometric parameters and the design geometric parameters of the mold parts after processing and assembly.
②. The concept of precision in mold production refers to a mode of thinking that is gradually formed in the production practice of enterprise employees and guides their production behaviors. It is a kind of quality awareness, that is, in the behavior of enterprise employees, it is always the quality of product accuracy awareness.
2. The content of mold accuracy includes four aspects: dimensional accuracy, shape accuracy, position accuracy, and surface accuracy. Since the mold is divided into two parts, the upper mold and the lower mold, the accuracy of the mutual position between the lower molds is the most important among the four precisions.
When CNC machining accuracy is high, molds are often overpowered and underpowered.
At present, the precision that can be achieved by a very precise mold is in the range of 0.1 to 0.01 mm. Compared with the previous mold, the accuracy has been greatly improved. However, components such as engines require accuracy below one-thousandth of a millimeter or less. Therefore, it is not yet possible to completely replace cutting with a mold.
The smoothness and roughness of the mold itself have greatly improved. However, the mold itself is also manufactured by a machine tool. If the accuracy of the machine tool used to manufacture the mold itself cannot pass the standard, the accuracy of the manufactured product will not be high.
