摘　　要：针对压铸件成形收缩性较大的特性,运用有限元数值模拟分析的原理,使用Pro/E软件对压铸件和压铸模造型,利用ANSYS软件对压铸模的温度场进行分析。实践证明,这种方法对改进模具结构,优化压铸工艺参数,提高压铸件质量有显著的效果。FEM method was used to predict the shrinkability of die castings during formation,and die castings and die casting die were modulated by the Pro/E system,meanwhile,temperature field in the die casting die were analyzed by the Ansys software.The results reveal that the method exhibits significant effects for modifying mould structure,optimizing processing parameters and improving quality of die castings.
