摘　　要：针对厚壁压铸件压铸工艺设计及参数选择困难的问题,以镁合金试棒厚壁压铸件为研究对象,在对其结构进行分析的基础上,以MAGMA公司MAGMASoft软件为CAE手段,对镁合金试棒压铸3种方案进行对比,通过充型、缺陷的模拟,选择最佳压铸工艺参数,即压射速度为1.26 m/s,内浇口速度为30 m/s,模具预热温度为220℃,浇注温度为620℃,此工艺参数下铸件质量最佳。In view of the thick wall die casting process design and parameters selection and difficult problems, with thick wall die casting magnesium alloy test bar as the research object, and, on the basis of the analysis of its structure, CAE mainly by means of MAGMA company MAGMASoft software, the three kinds of scheme are compared through the simulation of filling defect, the best die casting technology parameters are chosen. The injection speed is 1.26 m/s, the gate rate is 30 m/s, mould preheating temperature is 220℃, pouring temperature is 620℃, under which the casting quality is the best.
