摘要：
AZ91D magnesium alloy used as the automotive cooling system's pump impeller material, using the finite element analysis software ProCAST to numerical simulation for the temperature field and the flow field of die-casting process, analyzed the defects causes of magnesium alloy die-casting, and then determined the gating system. Based on the results of numerical simulation analysis, the design of ingate of the gating system set on central department is reasonable. It's benefit for smooth filling of liquid metal and uniforming the temperature field distribution, so as to reduce casting porosity, cold shut and shrinkage defects.
