摘    要:在间接挤压铸造过程中,充型液面的稳定性是铸件质量的保证。以平板铸件为研究对象,利用专业铸造软件 ProCAST进行数值模拟,分析了不同浇口形状与液面稳定性的关系。结果表明:带扩张角的浇道充型效果明显优于直浇 道,且随着扩张角的增大,其充型形态越平稳,液面凸起也越小;双浇道的浇注系统其充型效果不佳,液面波动加剧。

关 键 词:间接挤压铸造浇口形状对充型形态的影响

Abstract:The stability of filling process affects the casting quality in indirect squeeze casting. This paper took flat as research object, using numerical simulation, the professional casting analysis software Procast. to analyze the function of different gate shape with stability of filling process. The results reveal the filling effect of the sprue with divergence angle is much better than the direct sprue, and with the increase of the angle, the filling state becomes smooth and the surface projection is smaller; the gating system with double sprue filling has poor effect and the level fluctuation is obvious.
Keywords:indirect  squeeze  casting  filling form  ProCAST  gate  shape  stability of filling process
