摘要
为满足消失模铸造生产需求,设计了一种消失模铸造砂箱,砂箱制作完成后,各项尺寸精度符合技术要求,箱体透气性好,抽气室密封性好,提高了铸件的产量和质量,能够满足使用要求,取得了较高的经济效益。
A kind of sand box for lost foam casting was designed to meet production requirement. At completion all dimensions and precision of the sand box comply with technical requirement. The sand box shows good permeability at box and good leakproofness at suction chamber. The yeild and quality of casting were improved. The operation requirement was fulfilled and high economic effect achieved.
