管接口压铸模设计与制造

Design & Manufacture of Die Casting Die for Pipe Joint

带有外螺纹的管接口铸件采用斜滑块抽芯机构生产。由于铸件动模和定模的包紧力相近,设置了制动机构,使铸件在开模后留在动模中,便于取出铸件。本文在分析了管接口零件压铸工艺性的基础上,论述了模具的设计要点和工作原理,给出了实用的压铸工艺和模具结构,并改进了模具制造工艺。

he castings of pipe joint with outer screw are manufactured by a moving core mechanism of inclined sliding block.Because of the little difference between the magnitude of the moving die clutch force and of the fixed die clutch force,an arresting mechanism has been set to maintain the casting in moving die and removing easily the casting from the die.On analysis of die casting process of pipe joint part,the main points of design and the operation principle of the die have been dissertated,process of the die casting and a practical die structure presented,original manufacturing process of the die casting die im proved.
