摘要

运用Magma软件

对铝合金机油泵体的浇注系统进行了工艺优化和验证

对比了不同冷却工艺参数条件下

铸件凝固场的变化。模拟结果准确预测出了缩松、缩孔缺陷所在的位置。调整工艺后

再次进行模拟

缩孔、缩松缺陷消失

并且在实际生产中也未出现缩孔、缩松缺陷。

Abstract

By using the Magma software

the gating system for the aluminum oil pump was validated and optimized.In addition

solidification field was compared at different cooling parameter conditions.The simulation results reveal that the shrinkage porosity defects located in the part can be predicted accurately.After adjusting the cooling parameters

the simulated results reveal that the shrinkage porosity（holes）defects can be eliminated remarkably.The practical production is well agreement with simulated ones.
