[0002] When producing smart keys, it is necessary to embed fine palladium hardware strips into plastic. Generally, an injection molding machine is used to fix the fine palladium hardware strips and the plastic together. During injection molding, the fine palladium hardware strips need to be positioned. The existing in-mold positioning device for precision palladium metal parts still has certain defects when used, such as;
[0003] Traditional injection molding processes typically utilize a horizontal machine, combining general-purpose hard plastic (PC, PC / ABS, etc.) with soft plastics such as TPE. However, this overmolding mold combines hard plastic with hard plastic (transparent PC) and overmoldes metal palladium hardware. Because key palladium strips are relatively thin, the gap between the transparent PC hard plastic and the inner mold, and the fusion of the metal palladium hardware with the PC / ABS, can easily cause deformation during the overmolding process, resulting in displacement and impacting key performance. This results in poor positioning performance, and after overmolding, the molded key can easily become stuck in the mold, often lacking an auxiliary discharge structure. Utility Model Content
