大型卧浇机体下芯研箱定位工艺探讨

Discussion of the positioning technology of the core and mold assembly of large horizontal-pouring cylinder body

针对大型卧浇机体铸件在生产过程中尺寸超差的问题,分析产生原因,并提出一种下芯定位工艺,将下芯吊具和下芯定位框有效结合,提高大型铸件研箱尺寸精度,同时减轻操作者研箱劳动强度。

Aiming at the problem of oversize in the production process of large horizontal-pouring cylinder body, analyzes the reasons, and puts forward the process of cores positioning which makes the core hanger and the positioning frame combining effectively.The process improves size precision of large castings, and reduces the labor intensity of the operators.
