With the continuous development of industry, we can know the rapid development of various industries, so when in use, it may cause some damage, it may be caused by us in use, it may be caused by processing, so how to prevent the damage of the mold, let the following CNC precision parts processing small make up to tell you.
1. Good casting structure design
The wall thickness of the casting should be as uniform as possible to avoid the generation of hot joints, so as to reduce the thermal fatigue caused by the local heat concentration of the mold. The corner of the casting should be properly rounded to avoid the stress caused by sharp corners on the mold.
2. Reasonable mold structure design
1) Each component in the mold should have enough stiffness and strength to withstand pressure without deformation. Mold wall thickness should be sufficient to reduce deformation.
2) The gating system is designed to minimize the impact and erosion on the core.
3) Correct selection of tolerance fit and surface roughness of each component.
4) Keep the mold heat balance.
3. Standardize heat treatment process
The microstructure of materials can be changed by heat treatment to ensure the necessary strength, hardness, dimensional stability at high temperature, thermal fatigue resistance and material machinability.
Only with the correct heat treatment process can the best die performance be obtained, while the steel performance is controlled by quenching temperature and time, cooling rate and tempering temperature.
