预热对管路与铸件本体泄漏的影响

Effect of Preheating on Leakage of Pipeline and Casting Body

介绍了管路预埋压铸生产中,管路预热对管路与铸件本体结合间隙的影响,进而影响铸件泄漏率。在管路放入模具前,通过加热系统对管路进行加热,可以减小管路与铸件本体的结合间隙,降低铸件泄漏率。

This paper introduces the influence of preheating of the pipeline on the joint gap between the pipeline and the casting body in the production of pre-buried die casting,thus affecting the leakage rate of the casting.Before the pipeline is put into the mould,heating the pipeline through the heating system can reduce the joint gap between the pipeline and the casting body and reduce the leakage rate of the casting.
