【摘要】 针对复杂壳体类镁合金压铸件,进行了浇注系统和工艺参数设计,运用AnyCasting软件对其凝固过程进行了数值模拟,预测了压铸件中可能出现缩孔缩松的部位。在厚大部位增加溢流槽的数量和体积、降低浇注温度和模具温度,由于其补缩能力有限,以致缩孔缩松等缺陷减少不多;而在厚大部位设置内浇道,改变厚大部位的凝固顺序和增加对厚大部位的补缩,缩孔缩松明等缺陷明显减少。更多还原

【Abstract】 Pouring system and parameters are designed for magnesium die casting after analysis of the process of complicated housings type magnesium alloy castings. The numerical simulation of solidifying process of magnesium alloy die casting was performed with Anycasting software. Macro porosity probability in the die casting was forecasted. The optimum die casting process that is setting ingate in the part of thick partsis is proposed. The results show that the optimum die casting process could reduce the shrinkage and improve the quality of castings effectively.更多还原
