Abstract：
According to the structural characteristics of the complex stainless steel pump, the gating system was designed, and the thermo-physical parameters of the investment casting shell and the alloy were selected. Numerical simulation and production verification of wax injection molding process and casting solidification process of complex pump were carried out. The results show that by increasing the chillers and optimizing the size of the risers, the best scheme is selected, which shortens the trial production period and improves the pass rate of the products.
