Parameter Optimization of the Large-Scale Semi-Opened Copper Mould Die-Casting Based on Analysis of Temperature and Stress Fields

When using Large-scale semi-opened copper mould die-casting machine, it can reduce the shrinkage cavity and porosity, improve the surface roughness and the mechanical properties of the copper mould. But its process parameters are selected by experience, which result in unstable quality of the anode plate copper mould. In this paper, the temperature and stress fields of the copper mould were simulated using finite element method. And the effects of the initial temperature on the copper mould quality were studied further. The preliminary optimization scheme of the die-casting initial temperature was gained, which can provide the foundation for the further process parameters optimization of the copper mould die-casting.
