[0008] In particular, the top plate assembly includes a top plate slidingly arranged in the mold frame and a plurality of ejector pins linked to the top plate, respectively. The plurality of ejector pins move with the top plate, and one end of the ejector pin is inserted into the mold cavity and abuts against the terminal cover. The top plate assembly ejects the terminal cover through the plurality of ejector pins, so that the terminal cover can be smoothly demolded, thereby facilitating the improvement of the production efficiency of the injection molding mold.

[0009] In particular, the bottom plate of the mold frame is symmetrically arranged with two supporting columns, and the runner plate is arranged with two top rods matched with the two supporting columns. When the movable die plate and the static die plate are closed, the two supporting columns abut against the two top rods, respectively. The two supporting rods abut against the two top rods, so that the injection molding mold can be reliably closed, thereby facilitating the improvement of the working reliability of the injection molding mold.
