合理的浇注、排气系统与合理的冷却工艺是获得高品质压铸件的关键。

Abstract

Numerical simulation method was used to simulate the die-casting process of the aluminum alloy clutch housing to accurately understand the filling state and the casting defect distribution

and then to optimize the gating and exhausting system

greatly reducing the development time. Meanwhile

in trial-mold and trial-production process

origination of different defects was analyzed from the pouring parameters

process design and mould design

and the modified measures were proposed. The results show that a reasonable casting-exhausting system and cooling system are the keys to obtain high-quality clutch housing.
