摘要

汽车变速器后体是带有多个侧孔的复杂压铸件

尺寸较大

外侧面还存在窄长肋条和凸台。在压铸模的结构设计中

采用5向开模结构

凸模采用分体式（主型芯和上型芯）

侧型芯的成型采用斜导柱侧向分型和液压缸抽芯机构。通过对压铸件成型压力的计算

选择锁模力为6300kN的J1163型卧式冷室压铸机。

Abstract

Automobile variator back-shell with large dimension is a complicated die-castings where there are several side-hole and exist narrow-long rib and convex at outsides. Five-directional structure was adopted in design of die casting die

in which a departed structure was used for moving die design

including main core and top-core

and declined columniation parting and hydraulic drawing-core mechanism were used for forming of side-core. The horizontal cold chamber die casting machine with closed force of 6 300 kN has been selected by calculating filling pressure.
