The mold comprises a fixed mold, a movable mold, a sliding block capable of sliding out of the movable mold leftwards and a core rod obliquely arranged relative to the sliding direction of the sliding block, an inclined guide column is fixed to the fixed mold, an inclined guide groove allowing the inclined guide column to penetrate through is formed in the sliding block, a through hole is formed in the sliding block, the core rod is arranged in the through hole, one end of the core rod abuts against the fixed mold, and the other end of the core rod extends out of the through hole into a cavity. A jacking spring acting on the core rod in the direction away from the cavity is further arranged in the through hole, and a delay gap allowing the inclined guide column to move by a certain distance in the inclined guide groove in the mold opening direction during mold opening is formed betw
