摘要
分析泵体结构,设计泵体压铸工艺,以压射速度、浇注温度、模具预热温度为因素建立正交试验,采用ProCAST软件进行数值模拟,分析铸件产生的卷气和缩孔缺陷原因。结果表明,当压射速度为2.5 m/s、浇注温度为660℃、模具预热温度为230℃时,铸件产生的卷气和缩孔缺陷最少,并采用该优化参数进行试生产,获得了合格的产品。
Based on the structure of the pump body,die casting process was designed and simulated by the ProCAST software.Taking injection speed,pouring temperature,mold preheating temperature as factors,the orthogonal expriment was designed.Through analyzing the air entrainment and shrinkage defects in the pump body,the results reveal that there exists the least air entrainment and shrinkage defects with 2.5 m/s of injection speed,660℃of pouring temperature and 230℃of mold preheating temperature.Using the optimized parameters,the qualified pump body was produced successfully,meeting the actual requirement.
