摘要

根据ES11ZD水泵壳体结构设计压铸工艺

并使用Flow-3D软件对所设计压铸工艺进行数值模拟。结果显示

在初始方案中金属液在充型前期不能充满浇注系统

整体充型不平稳且有明显飞溅

铸件存在严重卷气和表面缺陷。通过调整横浇道形状、溢流槽大小和形状

对初始方案进行优化

并对优化方案进行模拟。结果显示缺陷被明显消除。

Abstract

The die casting process of ES11ZD pump shell was designed and optimized by Flow-3 Daccording to its structure.The results reveal that in initial design

metal liquid is not effort to filling the gating system fully in early filling process

and the filling process presents un-steady with apparent splashing

so the pump shell exists in the serious air-entrapment and surface defects.Through adjusting runner shape

overflow slot dimension and shape

the optimized design was simulated.The results reveal that the defects can be eliminated greatly.
