Abstract

According to the structure characteristics of the die-casting carburetor housing

orthogonal experiments were designed and the die casting process was simulated by ProCAST software.The die casting process parameters were optimized as follows:pouring temperature of 435 ℃

injection speed of 2.39 m/s and mould temperature of 220℃.Comparing the simulation results with the actual production experiments

it can be concluded that the optimized die casting process can reduce the shrinkage

porosity and air entrapment in the die-castings

improving the quality of the die-castings.
