Abstract： The main connect methods of plastic parts are as follows：Screw connection；clip connection; rivet connection and so on. Clip connection is quite common. Because there is no need to design a new mould for the integrated clip， so the integrated clip connection is cheaper， and The connection is firm， so the integrated clip connection is widely used in injection molding parts. This paper mainly introduces the design method of injection molding integrated clip from the aspect of forward design ， which has an important guiding significance to solve the problem of the failure of the injection molding clip in the assembly process of vehicle.

Key Words： Cantilever Clip; Stress; Strain; Insert Force; Pull-Out Force
