【摘要】 根据壳体的结构特点对其进行压铸工艺设计。通过对两种浇注系统利用ProCAST软件进行数值模拟,分析了缩孔、缩松产生的位置及原因,通过对比选择一种较优的浇注系统进行压铸工艺优化。结果表明,经过工艺优化,铸件无缩孔、缩松缺陷,且经过生产验证,满足技术要求。更多还原

【Abstract】 Based on the structure feature of the shell, design of die casting process was conducted, and two different gating systems were designed and simulated by using the ProCAST software. By comparison and analysis of the position and reasons of occurrence of shrinkage hole and shrinkage porosity, a better gating system was chosen, and then the die casting process was improved. The castings produced using the optimized die casting process had no shrinkage hole and shrinkage porosity, meeting technical requirements.更多还原
