When the fixed mold and the movable mold are clamped, a cavity can be formed by enclosing. The first inclined core-pulling mechanism and the positive core-pulling mechanism are both arranged at the upper end of the movable mold. One end of the first inclined core-pulling mechanism and the positive core-pulling mechanism close to the center of the movable mold are respectively connected with a first mold core and a fourth mold core. When the fixed mold and the movable mold are clamped, the first mold core and the fourth mold core extend into the cavity, and the end faces of the first mold core and the fourth mold core close to the center of the movable mold are mutually attached.
