摘　　要：基于Pro/E平台,设计汽车壳体件压铸模,包括分型面、浇注系统、溢流系统。将壳体CAD模型导入到有限元分析软件ProCAST,选择正确的初始条件和边界条件,将各种热物性参数定义给铸件材料,最终实现浇注过程的仿真,进而判断CAD模型建立的合理性。分析仿真结果可知,由于铸件各部分冷却速度不均匀,在某些地方存在严重的缩松,因此在模具上加工冷却水管道来避免冷却不均匀,很大程度上消除了缩松。运用模具CAD/CAE技术不仅提高了铸件质量,同时缩短了生产周期。Design the die-casting mold of automobile shell based on Pro/E, including parting surface, gating sysytem, overflow system. Importing the CAD model into ProCAST, and choosing the correct initial and boundary conditions. The thermophysical parameters of material should be define, at last the process of gating is realized, from this simulation, we can judge the reasonble of the CAD model. There are some shrikage because of the uneven of solidfication in some place, through the pipes of cooling water are machined in mold, the shrikage are disappear to a great extent. Combining the CAD and CAE technics can improve the quanity of cast, but also decrease the cycle of products.
