Design of Injection Mold for The Dual Card Fastening Interface

Abstract This design of injectiong mold was finished by using the two card fastening interface parts as an example。 Through the analysis of the plastic parts,the three-dimensional modeling of plastic parts and parts drawing was completed by using AutoCAD, UG and other auxiliary software。 After the analysis of the plastic part, it was found that there is a side hole and side recess in the plastic part, so the design have to use the side parting and core pulling mechanism to complete the mold release。 The combination of the inclined sliding block and the pushing pipe pushing mechanism is the innovation point of this design。 By consulting many  data, the design and check of gating system, forming parts, ejector mechanism and side parting and core pulling mechanism of fastening interface of plastic parts was finished, so purpose of this design was achieved。 In the end, the design of the injection mould for the double clamping fastening interface was successfully designed by using the side parting and core pulling mechanism to complete the stripping of the side hole and the side concave part。
