摘要

针对复杂壳体类镁合金压铸件

进行了浇注系统和工艺参数设计

运用AnyCasting软件对其凝固过程进行了数值模拟

预测了压铸件中可能出现缩孔、缩松的部位。在厚大部位增加溢流槽的数量和体积、降低浇注温度和模具温度

由于其补缩能力有限

以致缩孔、缩松等缺陷降低不明显;而在厚大部位设置内浇道

改变厚大部位的凝固顺序和增加对厚大部位的补缩

缩孔、缩松明等缺陷明显减少。

Abstract

Pouring system and processing parameters were designed for die casting complicated magnesium alloy housings.The solidification process of die casting magnesium alloy was simulated with the help of AnyCasting software to forecast macro porosity probability in the die casting.Through adding numbers and size of overflow at thick location

decreasing pouring temperature and mould temperature

effects of eliminating shrinkage porosity（holes）exhibit weak as a result of low feeding ability.However

through setting ingate at the thick location to modify solidification sequence and increase feeding ability of thick location

defects such as shrinkage porosities（holes）can be eliminated effectively.
