汽车车灯支架压铸工艺CAE分析及模具设计

Die-Casting Process CAE Analysis and Die Design for a Car Lamp Holder

分析了汽车车灯支架的结构特点,进行了压铸工艺设计,并应用ProCAST软件对该铝合金压铸件的充型过程、压铸模具热平衡和温度场进行了数值模拟分析,预测缺陷产生的位置及原因,根据预测结果对模具结构进行了优化。实际生产表明,采用优化后的模具设计方案提升了铸件质量。

The structural characteristics of a car lamp holder was analyzed,and its die-casting process was designed.Themold filling process,thermal balance and temperature field of the die-casting die were numerically analyzed by using of ProCAST software,and the positions and causes of the defects generated were predicted.The die-casting die wasmodified according to the prediction results.The practical production proved that the casting quality was improved after the optimized die design scheme was applied.
