摘要
在零件的压铸过程中,浇注排溢系统起到极为重要的作用。文中以某汽车干燥器阀体为研究对象,通过专业软件ProCAST对压铸过程进行了数值模拟,对液态金属在压力下的充型和凝固两个过程进行了研究,预测了缩松缩孔等缺陷,然后以此为依据,有针对性地进行浇注排溢系统优化。最后对优化后的方案进行模拟与生产验证,认为优化方案可以使得压铸件符合生产要求。
In the die-casting process of parts,the pouring-venting-overflow system plays an extremely important role.The paper takes the automobile dryer valve body for a certain automobile as the research object,and the professional software ProCAST is used to study the two processes of filling and solidification of liquid metal under pressure and such defects as the shrinkage porosity are predicted.Based on the simulation results,the pouring-venting-overflow system is optimized in a targeted manner.Finally,the optimized die casting process is simulated and the production verification is carried out.It is believed that the optimized system can make the die castings meet the production requirements.
