Description

Technical Field

[0001] The utility model relates to the field of connector production, in particular to an electronic connector injection mold. Background Art

[0002] Electronic connectors are also often called circuit connectors, electrical connectors, and conductor devices that bridge two conductors in a loop so that current or signals can flow from one conductor to another. An electronic connector is an electrical system that provides a separable interface for connecting two sub-electronic systems. Simply put, the component used to complete the electrical connection between circuits or electronic machines is called a connector, which is the bridge between the two.

[0003] When producing electronic connectors, it is necessary to push the injection nozzle into the mold to spray the injection liquid. During the injection molding operation, due to different injection pressures, the injection liquid will solidify and harden during the long-term transportation process, and then get blocked in the injection molding tube. When the injection molding tube is blocked, it cannot be inspected inside the injection nozzle and other structures and cannot be discovered in time. Therefore, continuous injection molding operations will cause damage to the injection molding device. The existing equipment has a complicated troubleshooting process and poor maintenance efficiency, which has a very large negative impact on subsequent work.

[0004] Therefore, it is necessary to invent an electronic connector injection mold to solve the above problems. Utility Model Content

[0010] Preferably, the output end of the small motor is sleeved with a synchronous transmission belt, and the end of the synchronous transmission belt away from the small motor is sleeved with a transmission gear, and the transmission gear is rotatably connected to the bottom wall of the middle groove.

[0011] Preferably, one end of the transmission gear away from the small motor is meshed with a driven gear, the driven gear is rotatably connected to the top end of the drop tube, and the inner side wall of the driven gear is fixedly connected to the bottom end of the stirring rod.

[0012] Preferably, a cooling water inlet is provided on the top of the upper mold, and a water outlet valve is provided on one side of the middle groove.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
