Simulation results show a smooth filling, uniform temperature distribution and few flaws such as gasinclusion and cold shut. A casting with a good quality was obtained.
Gas hole and inclusion can be reduced by properly increasing thickness, and quality of the chilling layer, uniformly spraying and cleaning the mould cavity on time.
适度增加激冷层厚度，提高激冷层品质，均匀喷涂并及时清理模具型腔，可减少气孔和夹杂物缺陷。
