铸造CAE模拟分析低压铸造泵轮缩松缺陷

Analysis of Dispersed Shrinkage of Pump Impeller in Low Pressure Die Casting by CAE Simulation

采用铸造CAE数值模拟软件AnyCasting对低压铸造中金属液的流动、凝固进行模拟仿真,分析了铸造过程中泵轮出现的铸造缺陷。分别研究了阀体铸造过程中不同的工艺方案对产品质量的影响,并将模拟结果与实际情况进行对比,较好地指导了生产。

In the study, the flow and the solidification of molten metal in low pressure die casting(LPDC) were simulated by using the foundry CAE software AnyCasting, and the dispersed shrinkage defect in pump impeller during the casting process was analyzed. Furthermore, the study also investigated the effects of original and improved casting processes on the quality of valve body castings, and the simulation results were compared with the practical situation, which will give some good guidance in the practical production.
