How can CNC prevent mold damage?

by:Foxron     2021-12-01
With the continuous development of industry, we can know the rapid development of various industries, so when it is used, it may cause certain damage, it may be caused by us when it is used, or it may be caused by processing. Yes, so how can we prevent the damage of the mold, let the editor of CNC precision parts processing tell you about it.

1. Good casting structure design

The wall thickness of the castings should be as uniform as possible to avoid hot spots and reduce the thermal fatigue caused by the local heat concentration of the mold. The corners of the castings should have appropriate casting fillets to avoid stress caused by sharp corners on the mold.

2. Reasonable mold structure design

1) Each component in the mold should have sufficient rigidity and strength to withstand pressure without deformation. The wall thickness of the mold must be sufficient to reduce deformation.

2) The gating system is designed to minimize the impact and erosion on the core.

3) Correctly select the tolerance and surface roughness of each component.

4) Maintain the thermal balance of the mold.

3. Standardize the heat treatment process

The metallographic structure of the material can be changed by heat treatment to ensure the necessary strength, hardness, dimensional stability at high temperature, thermal fatigue resistance and material cutting performance.

The correct heat treatment process can get the best mold performance, and the performance of the steel is controlled by the quenching temperature and time, cooling rate and tempering temperature.
