Abstract

Numerical simulation method was adopted to predict the filling process of liquid aluminum alloy and defect distribution in the die casting aluminum alloy side cover of gear-box and then to optimize the gating-exhaust system

so the development time of die casting die was shortened significantly.Meanwhile

during mould-trial and production-trial

origination of different defects from the casting process and mould were analyzed

and countermeasures were presented.The results show that a reasonable casting-exhaust system and the cooling system are the keys to obtain high-quality die castings.
