摘　　要：分析了箱体零件产品图,包括箱体零件的精度、表面粗糙度和结构;进行了压铸工艺设计,包括压铸压力、温度和时间工艺参数;进行了模具结构三维设计,包括分型面选择、型腔数目计算、动模和定模设计、浇注系统设计,推出机构设计和结构零件设计等;最后通过箱体零件充型过程模拟,对压铸工艺进行了优化。模拟结果表明:箱体零件模具设计合理,整个充型过程没有填充不足的情况。The case part＇s product map was analyzed, including case part＇s precision, surface roughness and structure; the die casting technology parameters for case parts were designed, including die-casting pressure, temperature and time; the 3D mold structure was designed, including selectiing parting surface, calculating cavity number, designing movable mold and fixed mold, designing gating system, launch mechanism, and part＇s structure, etc. Finally, the die-casting process was optimized by the simulation on the case part in filling process. The simulation results show that the design of the case part＇s mold is reasonable without underfill in the whole filling process.
