摘　　要：铝合金支座压铸生产中存在工艺性能差、模具寿命低、成品率和生产效率低等问题。基于实际生产中存在的问题,本设计在对该产品压铸工艺分析的基础上,对压铸模具进行了设计。采用液压抽芯机构来完成四个方向的抽芯动作,并在其中一个大型芯上开设了溢流槽和冷却水道;深孔型芯部位采用螺旋式不拆模更换型芯的结构。改进设计的模具在实际生产中,克服了冷隔缺陷,提高了生产效率。Some problems, such as poor die-casting properties, short die service life, and low productivity appeared in the production of die casting aluminum alloy abutment. Based on the analysis of the die-casting process, the die casting die was redesigned. The slides in four orientations with hydraulic core pulling structure were designed according to the analysis on the workpiece structure, and the overflow groove and the cooling water channel were added to the big core, at the same time the screw structure was used in deep-hole core. The practical production shows that with the improved dies, the cold shuts defect is eliminated and meanwhile the production efficiency is increased.
