Abstract

According to the structural characteristics of the radiator, two different gate structures were designed. The filling process of metal liquid in different gate structures was simulated by using the simulation software FLOW-3D, the size and location of possible defects in die casting were predicted, and the best design scheme of gate and overflow trough was put forward. The results show that under the conditions of pouring temperature of 680°C, preheating temperature of mold of 220°C and pouring speed of 60m/s, the most reasonable design scheme is that the whole casting can be filled with molten metal evenly and the concentration of surface defects is low.
