摘　　要：通过ProCAST软件对除草机不锈钢支架进行熔模铸造的数值模拟,预测铸件缩孔缺陷分布情况,并对其浇注系统进行改善。利用正交试验对铸件的工艺参数进行研究,通过分析获得工艺参数的最佳方案。对该结果进行数值仿真以及实际铸造,发现铸件缺陷明显减少,这为不锈钢支架的生产提供了参考。The stainless steel bracket of weeding machine was numerically simulated by investment casting using ProCAST software.The shrinkage defect of the casting was predicted and the pouring system is improved.The process parameters of castings were studied by the orthogonal experiment,the optimum scheme of process parameters was obtained by analysis.Through numerical simulation and actual casting,it is found that the casting defects are obviously reduced,which provides a reference for the production of stainless steel bracket.
