Numerical Simulation of Low Pressure Investment Casting of Large and Thin-walled Magnesium Alloy Grid Castings
The hydraulic principle of gating system design was adopted and gating system of ZM6 grid castings was optimized by low-pressure casting with vertical gap runner.The liquid flow and temperature field distribution during the pouring process were simulated and analyzed by ProCAST software.The results indicate that using hydraulic prin-ciples,increasing the contact area between the gap runner and the casting,as well as the number of vertical cylinders,the filling effect can be significantly improved and the temperature gradient at various points of the casting during the solidification process was reduced.The optimized gating system design was adopted to achieve the formation of grid castings combined with specialized grinding heads for post casting repair,meeting the requirements of quantity produc-tion of grid castings.
