[0022] A set of positioning mechanisms including a positioning seat 3, a slider 4 and a positioning sleeve 5 is added to the outer surface of the core rod 6. When the front mold 1 and the rear mold 2 are in the open state, the positioning mechanism is in the positioning state of injection molding. The slider 4 is supported by the rebound thrust of the spring 8, and the positioning mechanism is in the positioning state of injection molding. After the front mold 1 and the rear mold 2 are molded, the insert block 10 is inserted into the oblique slot of the slider 4 and pushes the slider 4 to move, so that the slider 4 and the positioning sleeve 5 are withdrawn from the positioning state, thereby realizing the injection molding positioning in the molding groove 11.
