摘　　要：介绍了一种有箱V法制芯工艺。此制芯方法同砂型造型方法一样,也用V法制作,芯砂与型砂相同,均为干散砂,铸件落砂后不用分离芯砂,大大减少了型砂清理工作量,提高了型砂和铸件质量,降低了铸造成本。本方法特别适合制造汽车后桥壳铸件以及三通、接头、弯头类铸件。This paper introduces a new core making method called "box V-process core making". The core making process is the same as the sand mold molding method. The sand core is made by V process and the core sand is the same as the mold sand. There is no core sand to be removed after casting shakeout. It greatly reduces the workload of molding sand cleaning, improves the quality of mold sand and castings, and reduces the production cost. It is especially suitable for the production of rear axle housing, tee bend, joint, angle fitting castings.
