Design and Analysis of the Injection Mould for the Five-pass Joint

Through analysis on the structure of five-pass joint and technology problems in injection forming, and the influencing factors such as temperature of mould and melt, injection time and injection pressure, an injection mould with single cavity was determined. The design of molding parts, hydraulic pressure side core-pulling mechanism and injecting system, the calculation of dimensions and working process of the mould were discussed in detail. The results show that the mold can run reliably and flexibly, the precision of plastic components can achieve the requirements of the design and the external surface is smooth.
