方形壳体的压铸成形

介绍了方形壳体铸件的模具结构，论述了其工作原理。针对侧面带孔的薄壁深腔壳体铸件来说，零件脱模和侧孔抽芯是模具设计的重点，为此采用了弹簧侧抽芯机构和摆钩式顺序分型机构。模具较紧凑，结构较新颖。

Formation of Oblong Shell by Die Casting

The die structure of oblong shell has been introduced with its operational principle discussed about. For the thin-walled deep shell with side hole, the die stripping and core pulling would be difficult in die design, so side core pulling structure with springs and orderd parting structure have been adopted. The die is compact with new structure.
