PROBLEM TO BE SOLVED: To provide an injection mold equipped with a mechanism for removing a molded article which is simply structured and easily applicable to a conventional mold. SOLUTION: This injection mold 1 has a cavity-side half 2, a movable half 3 and a sliding block 4 which obliquely moves up and down on a slope 2b. The sliding block 4 has a first guide hole 4a in which an extrusion pin 9 is slidably fitted and the cavity-side half 2 has a second guide hole 2d in which a guide pin 10 is slidably fitted. The extrusion pin 9 and the guide pin 10 are rotatably connected together by means of a connecting pin 11. The sliding block 4 moves inwardly when the sliding block 4 is obliquely raised by the guide pin 6. The extrusion pin 9 also rises but relatively protrudes from the side surface of the sliding block 4 by the upward parallel movement of the extrusion pin 9 by the guide pin 10. Consequently, the folded-back part Wa of a bumper W is extruded laterally. COPYRIGHT: (C)2004,JPO
