改进后的铸件毛坯结构和模具型芯能够减少和消除了缩孔及气孔缺陷。

Abstract

Aiming at the problem of high shrinkage cavity and blowholes in ADC12die-castings

the filling process was simulated by the ProCAST to analyze the high forming area of shrinkage cavity and blowholes and predicts the possible defects in other areas combining with the structural feature.The existing mould process was evaluated and improved.The results show that the optimized structure of casting blank and mould core can eliminate shrinkage cavity and blowholes.
