摘　　要：在对铝镁合金压铸件进行开发工作中,可以通过华铸CAE软件对充形进行模拟,达到对压住工艺方案进行分析和优化的目的。结果证明,原本方案中使用内浇口金属液充型形式经常会出现来自于铸件型顶部和底部位置的夹渣或卷气问题。而经过方案改进之后,以增加辅助内浇口的形式来保障充型,可以很好的改善铸件底部或顶部发生或卷气问题。确保铸件在实际生产中可以达到98%以上的合格率。In the development of aluminum magnesium alloy die casting,the filling can be simulated by Huazhu CAE software,so as to analyze and optimize the pressing process.The results show that the problem of slag inclusion or air entrainment from the top and bottom of the casting mold often occurs when the internal gate is used in the original scheme.After the improvement of the scheme,the problem of bottom or top of casting or air entrainment can be well improved by adding auxiliary inner gate to ensure mold filling.It is ensured that the qualified rate of castings can reach more than 98% in actual production.
