Information
1. Check whether the mold temperature is normal, and appropriately reduce the pouring temperature of the alloy liquid and the mold temperature;
2. Check whether the ratio of the release agent is abnormal, try to replace the release agent, and adjust the spraying position and spraying amount;
3. Polish the surface of the die-casting mold, and polish the nitrided mold carefully to prevent the nitride layer on the surface from being destroyed and forming a more sticky situation;
4. Improve the design structure of the pouring system to prevent the alloy liquid from continuously washing the cavity wall or core;
5. Modify the mold cooling system, adjust the die casting process parameters, appropriately reduce the injection speed, and shorten the two-speed stroke.
6. Try to grind a few transverse grooves on the moving mold, 0.2-0.3mm is enough, the die-casting parts will be bright and will not be damaged. This can increase the tightening force of many moving mold sides and bring the die-casting parts to the moving mold.
