摘　　要：考虑到管接头工件内为通孔、外带环状凹槽的特征,结合其压铸成形工艺,研制出侧抽芯压铸模。合理选取浇注及排溢系统,计算并确定内浇道尺寸;对侧抽芯机构进行设计,给出了主要压铸工艺参数。实现了合金液的平稳充型,获得了内外质量均较好的铸件。Considering the tube joint with hole inside and annular groove outside, combined with its die casting process, a pulling core casting mold was developed, selecting rational pouring and exhaust systems, and determining the shape size of inner runner. The pulling core mechanism thoroughly was designed and the main die casting process parameters were given to achieve the smooth filling of liquid alloy and obtaine the castings with well internal and external quality.
