摘　　要：运用ProCAST数值模拟软件,对设计的铝合金端架进行了流动场和温度场的数值模拟。根据模拟结果改进了浇铸系统,确定了合理的压铸工艺参数:浇注温度610℃,模具预热温度220℃,压射速度2m/s。通过生产出的模具进行压铸生产实验,得到了合格的端架压铸件,验证了模拟结果可以应用于实际生产中。By analyzing temperature field and flow field of die-casting process of aluminum end bracket resulted from numerical simulation, using ProCAST software, the structure of die-casting die was refined ,and end bracket＇s property was found to be better at where pouting temperature comes to 610℃, mold preheating temperature up to 220℃ and the injection speed is 2m/s. Qualified aluminum end bracket produced from designed die-casting die was obtained. It is testified that numerical simulation works on die-casting manufacture.
