Abstract

According to the structural characteristics and quality requirments of the pump shell

the design of die casting process for the pump shell was carried out.The numerical simulation of the filling and solidification process of the initial design was carried out by using Flow-3 Dsoftware

and the position and cause of the shrinkage defects were analyzed.Aiming at these problems

the method of enlarging the ingate and adding the overflow slot at the defective position was adopted

and the optimization scheme was designed.The simulation results show that the optimized process can reduce significantly the entrapped-gas in the castings and improve the casting quality to meet the requirements.
