摘要
根据汽车发动机支架结构进行压铸工艺设计,利用ProCAST软件对铝合金发动机支架压铸工艺进行数值模拟,分析了铸件缺陷产生的位置及原因,通过对比选择出一种较优的工艺设计,并进行改进优化。结果表明,获得的优化方案消除了铸造缺陷,提升了铸件品质,经生产验证后满足技术要求。
Based on the structure feature of the automobile engine bracket,the design of die casting process of the automobile engine bracket was conducted.Through numerical simulation with ProCAST software,the location and causes of casting defects were analyzed,and a better process design was selected and improved through comparison.The results show that the obtained optimization measures eliminated casting defects and improved casting quality,and the castings met the technical requirements after production verification.
