摘　　要：选择半封闭底注式浇注系统,借用Pro CAST仿真软件,通过正交试验对变速箱箱体消失模无冒口铸造的工艺参数进行了优化。研究表明:浇注温度为1 460℃、泡沫模样密度为20 kg/m3、负压度为0.05 MPa时铸件的缩孔、缩松倾向小。Selecting enlarged and bottom gating system, the process parameters for gear-box housing in non-riser lost foam casting were simulated and optimized with ProCAST software based on orthogonal test. The simulation results show that, when the pouring temperature is 1460℃, pattern density is 20 kg/m3, negative pressure is 0.05 MPa, the tendency of shrinkage porosity and cavity is minimal.
