Mould experts believe that the selection of advanced mould technology is the inevitable trend for fierce competition at the moment, and the most important thing is to increase the competitiveness of mould itself to meet the market demand. It is not only the requirement of mould industry development, but also the voice of automobile and other industries to improve the high precision of mould.
Strengthen the understanding of mould precision meaning
1. Die refers to the well formed equipment used for batch forming, stamping and other finished products. Mold accuracy includes the accuracy of parts obtained in machining and the quality consciousness of ensuring the accuracy of products during manufacturing. However, generally speaking, mold accuracy mainly refers to the accuracy of working parts of mold.
① Precision in die machining means that the essential geometric parameters of die parts after machining and assembly are in line with the design geometric parameters.
② Precision in mold making means that the enterprise employees gradually create a mode of thinking, a quality consciousness, which guides the employees to make actions. That is to say, in the actions of the enterprise employees, they always implement the quality consciousness of product precision.
2. The content of mould precision includes four aspects: dimension precision, form precision, position precision and surface precision. Due to the two parts of the upper die and the lower die during the working time of the die, the mutual position accuracy between the upper die and the lower die in the four kinds of accuracy is very important.
When the machining accuracy is very high, the mold often has more than enough force. Now the precision of a well-designed mold can reach within the range of 0.1-0.01 mm. Compared with the previous mold, the precision is still a big step higher. However, the accuracy of these components, such as engine, is required to be less than one thousandth of a millimeter, or even smaller. Therefore, it is impossible to replace the cutting process completely with the die at present.
Now, the brightness and roughness of the mould itself still have a great leap. However, the mold itself is also out of the machine tool manufacturing. If the accuracy of the machine tool manufacturing the mold itself can not pass the standard, the accuracy of the products manufactured out of the manufacturing will not be high.
