Positioning wedges 120 are provided at both ends inside the fixed template 14 to ensure the accurate position of the main mold core 117. The movable template 17 is arranged opposite to the fixed template 14. When the mold is closed, it forms a closed space with the fixed template 14, which is the cavity of the mold. A hot runner channel 114 is provided on the movable template 17 to maintain the mold temperature and ensure good fluidity of the plastic. The runner plate 18 is located above the movable template 17 and is responsible for guiding the molten plastic into the mold cavity. The top plate 19 is located above the runner plate 18, and a gate 111 is provided at the middle position to introduce the molten plastic from the runner plate 18 into the mold cavity. The gate 111 connects the top plate 19 and the runner plate 18 and is the entrance for the molten plastic to enter the mold cavity. The nozzle 110 is located inside the gate 111 to ensure that the molten plastic can flow smoothly into the mold cavity. The main mold core 117 is located inside the fixed template 14 and cooperates with the side mold core 118 to form the basic shape of the battery housing.
