Abstract

According to the structural characteristics of pump body parts

the gating system

exhaustingoverflow system and die-casting process parameters were designed.Filling and solidification process was carried out with the ProCAST software.According to the simulation results

the casing process was optimized

and the reasonable die-casting process parameters were determined.With casting temperature of 630 ℃ and the mold preheating temperature of 220 ℃ as well as the injection rate of 1.5 m/s

the qualified pump body was produced

which showed that the simulation results could be used in the actual production.
