Description

Technical Field

[0001] The utility model relates to the technical field of wire harness plug-ins, in particular to a wire harness plug-in injection mold with an auxiliary demoulding structure. Background Art

[0002] The basic working principle of injection molding is to melt plastic particles at high temperature, then inject them into the mold cavity under high pressure, and then inject the molten plastic into the mold cavity, and finally cool and solidify into the desired shape of the product. The wiring harness plug-in refers to the positioning connector used to connect the wiring harness to the device or controller unit. It usually consists of two parts: plug-in (male head) and connector (female head). These plug-ins play a vital role in electronic engineering. They can ensure the effective connection between circuits, thereby realizing the flow of current and the transmission of signals.

[0003] For example, a car wiring harness plug-in injection mold is recorded in the patent with patent announcement number CN215242530 U, in which the recorded solution includes an upper mold base, a lower mold base and a base plate for supporting the lower mold base, an injection molding platform is arranged at the bottom of the base plate, a positioning column is fixedly connected to the lower surface of the base plate, a positioning hole corresponding to the positioning column is opened on the upper surface of the injection molding platform, clamping arms are arranged on both sides of the base plate, and a synchronous driving mechanism for driving two clamping arms to move synchronously toward or in opposite directions is arranged on the lower surface of the injection molding platform.

[0004] The above case has the problem of being unable to perform auxiliary demoulding. Since the wiring harness plug-in is often embedded in the mold after the injection molding is completed, it is not convenient to take it out, which affects the subsequent injection molding. If the operator takes it out directly, there will be certain safety hazards. Utility Model Content
