摘　　要：针对减速器箱盖壁厚较大及轴端环形槽倒扣位脱模困难的特点,设计了1副以铝合金A356为成型材料的压铸模。采用搅拌型半固态压铸解决铸件内部容易出现孔洞及致密度不足的问题,提高铸件质量和强度;采用镶件套压铸解决铸件脱模困难的问题;采用定模组合滑块清理镶件孔的渣屑,保证模具的可持续生产,取得了较好的经济效益。In view of the difficulty in forming the outer annular groove of the axle end of the reduc⁃er gear box cover and the large wall thickness of the product,a die-casting die that made of A356 aluminum alloy was designed.The internal holes and insufficient density of the castings was solved by stirring semi-solid die casting,which improved its quality and strength.The inserts were used to solve the difficulty demoulding,and the combined sliders in the fixed half of die were used to clean up debris from insert holes,which was to ensure the sustainable production.
