摘要

针对某支架产品浇不足缺陷

分析了其产生的原因

发现缺陷部位最后充型

而又最先凝固。采用提高型壳温度和浇注温度

在铸件容易产生浇不足处的型壳外表面粘贴保温棉

减少型壳层次以增加型壳透气性

有效解决了该铸件浇不足的问题。

Abstract

Misrun defects can be generated easily in some investment casting bracket

which is attributed to the last filling and first solidification at the misrun position.Misrun defects can be eliminated effectively in the investment casting bracket by some measures

such as increasing shell temperature and pouring temperature

covering warm-keeping fibre at shell surface easily generated misrun as well as reducing shell layer to improve the permeability of shell mold.
