1. Reasonable casting structure design: avoid excessively thin casting wall thickness, evenly distribute wall thickness, and reduce thermal fatigue caused by local heat concentration in the mold. Casting corners should be appropriately set at the corners of the casting to avoid sharp corners on the mold, which can cause stress concentration.
2. Reasonable mold structure design: Each component in the mold should have sufficient stiffness and strength to withstand pressure without deformation. The mold wall thickness needs to be sufficient to reduce deformation. When designing the pouring system, efforts should be made to minimize impact and erosion on the core, and to correctly select the tolerance fit and surface roughness of each component. Maintain thermal balance of the mold.
3. Standardized heat treatment process: Through heat treatment, the metallographic structure of the material can be changed to ensure necessary strength, hardness, dimensional stability at high temperatures, thermal fatigue resistance, and material cutting performance. The correct heat treatment process is the key to achieving optimal mold performance.
4. Die casting production process control: Pay attention to cleaning the residual fragments on the surface of the mold to avoid uneven force on the surface of the mold and deformation caused by these excess materials during mold closing. Strictly control alloy melting and reduce gas in the molten metal.
5. Maintenance and upkeep of molds: Regularly inspect and maintain molds, including cleaning, lubrication, tightening, etc., to avoid damage caused by mold failures.
