摘　　要：基于UG平台设计了铝合金壳体压铸件的浇注系统和排溢系统,并运用铸造模拟软件Anycasting进行了数值模拟。通过分析铸件的充型及凝固过程,判断设计的合理性。模拟结果表明,在压射速度为2m/s,浇注温度为670℃,模具预热温度为180℃的条件下,铸件充型平稳,无明显缺陷。Pouring system and exhaust overflow system of the aluminum alloy shell die castings were designed based on the UG platform, and the casting simulation software Anycasting was used to simulate. By the analysis of casting filling and solidification process the rationality of the design was judged. The simulative results show that the cavities of the casting are stably filled with no sig- nificant defect under the condition that injecting speed is 2 m/s, pouring temperate is 650 ℃, die preheating temperature isl80 ℃.
