The upper mold descends and closes with the lower mold to perform injection molding. After the injection molding is completed, the upper mold rises and separates from the lower mold. The upper part of the push rod is fixedly connected with the telescopic rod. The setting of the telescopic rod ensures that when the push rod moves upward, it will temporarily not generate force on the product, thereby preventing the push rod from damaging the product. The injection molding machine is used to push the push plate to move, so that the push plate drives the push rod to move upward, and the telescopic rod on the push rod shrinks. During the upward movement, the push rod ejects the molded workpiece from the lower mold, making it easy for staff to pick up the molded workpiece, thereby improving the use effect of the equipment.
