基于CAE的盖板压铸工艺设计及优化

Cover Plate Die-Casting Process Design and Optimization Based on CAE

摘要: 在分析铸件结构特点的基础上，使用传统经验公式对盖板的压铸工艺进行设计，同时使用CAE (Computer Aided Engineering)软件对铸件进行数值模拟。模拟结果表明，初始工艺中铸件的部分位置缩松、缩孔现象严重且存在冷隔现象。生产试模结果与初始工艺数值模拟结果基本一致，初始压铸工艺无法满足生产要求。依据试模和数值模拟结果对初始压铸工艺进行改进，添加并改变了溢流槽的尺寸和位置，改空冷为水冷。对改进后的压铸工艺进行数值分析和生产试模，缩松、缩孔和冷隔现象得到大幅改善，满足生产质量要求。

Abstract: On the basis of analyzing the structural characteristics of the casting, traditional empirical formulas were used to design the die-casting process of the cover plate, and CAE (Computer Aided Engineer-ing) software was used to numerically simulate the casting. The simulation results show that some parts of the casting designed in the initial plan have serious shrinkage, shrinkage cavities and flow marks. The production trial mold results are basically consistent with the initial process numerical simulation results, and the initial die-casting process cannot meet production requirements. Based on the trial mold and numerical simulation results, the initial die-casting process was improved, the size and position of the overflow groove were added and changed, and air cooling was changed to water cooling. Numerical analysis and production test molds were conducted on the improved die-casting process. The phenomena of shrinkage porosity, shrinkage holes and flow marks were greatly improved, meeting production quality requirements.
