本文主要介绍了在没有石膏真空搅拌设备及铸造时没有加压结晶手段的情况下,采用多次浇注的新工艺,成功地用石膏型浇注出各种形状复杂、型腔深及机械加工难以进行的锌基合金模具型腔的经验,解决了长期以来在一般铸造条件下用石膏型浇注模具型腔会在型腔顶部出现大量气孔的缺陷。 This paper mainly introduces the new technique of pouring many times in the absence of gypsum vacuum mixing equipment and without the means of pressure crystallization during casting, successfully casting gypsum castings of various shapes, deep cavities and difficult machining Of zinc-based alloy mold cavity experience, to solve the long-term casting conditions in the general cast gypsum mold cavity will appear in the cavity at the top of a large number of stomatal defects.
