(2) When opening the mold, first open the upper mold and pull out the side mold, and then push the push rod to push out the insert mold and the molded product at the same time, so that there is no scratches and zero defective products in the whole process, and the preparation of such products with multiple concave side surfaces is fully realized. (3) The pull rod is a screw rod, and the pull rod is connected to a fixed block through a rolling bearing. The side core pull seat is fixed to the rightmost side of the lower mold. The screw nut is fixedly connected to the side core pull seat, and the pull rod and the screw nut form a threaded connection. In this way, the pull rod can be moved along the screw nut by rotating the screw rod to realize the dragging of the side mold. At the same time, the rotation movement of the pull rod can be realized by electric means to achieve automation. (4) The push rod includes a first push rod and a second push rod. The first push rod penetrates the lower mold and reaches below the insert mold. The second push rod penetrates the lower mold and reaches below the molded product in the mold. Under the action of the push rod fixing plate and the ejection plate, the multiple push rods can smoothly push the molded product out of the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS
