Die processing refers to the processing of molding and billet tools, in addition to shear die and die cutting die. What are the characteristics of these molds? Xiaobian today for you to explain.

1. Generally, there are molds composed of concave film, punch and film frame, and the control accuracy is higher. Some may also be modules that have multiple pieces put together. Therefore, the combination of upper and lower die, the combination of insert and cavity, and the combination between modules require high machining precision.

2. In the production of small batch molds, it is not mass production, but only one pair is produced in most cases.

3. The use of molds has a life. When the use of a mold exceeds its life, the mold should be replaced in time, so the production process of the mold has a certain repeatability.

4, milling, boring, drilling, reaming and tapping processes will also be used in frequent mold processing.

5, the main material of the mold is high quality alloy steel, some molds with a long service life are often made of Crl2, CrWMn and other Leytensitic steel. The production and processing of this material is very strict, so the processing process can not be ignored, and the thermal deformation treatment is also an aspect of processing that needs to be treated seriously. To sum up, in the selection of airports to meet the processing conditions as far as possible, such as functional strength, high precision machine tools, better rigidity, better thermal stability with anti-type function.

6, some surface shapes are a combination of a variety of surfaces, such as car cover parts, aircraft, parts, toys, household appliances, etc., so the mold cavity surface is very easy and complex, some need to be processed through mathematical calculation.

7, some molds in the production process neither drawing, nor data, only through the physical imitation processing, which requires high imitation precision, no deformation.

The introduction of the characteristics of mold processing is here today.
