This paper introduces the process of the threeway pipe injection mold design. Through to the analysis of the technology of plastic parts, determine its main molding process parameters, the design of injection mould threeway pipe each of the system, such as gating system, orientation and the position of the institutions, side parting and corepulling mechanism, ejection mechanism, the parting surface, cooling systems and exhaust slot. And checked the selected injection molding machine parameters, finally draw mold assembly drawing, pletes the preparation. This injection mold is two joint surfaces structure, dying structure adopted one module one cavity, used the side corepulling mechanism of a roller type slide,using the push rod plastic parts prolapse, it is a reasonable structure, reliable operation. The whole design process not only using traditional design method, still use of the CAD, PRO / E and other technology greatly improving the design efficiency. The design of injection mould can strengthen the understanding of forming principle, while exercising the injection molding mould design and manufacturing ability.
