PURPOSE:To smoothly and certainly mount and detach a mold constituting part by providing the mold constituting part forming the surface of a resin molded product in a freely detachable manner and forming a rack to the mold constituting part and meshing a gear mounting and detaching the mold constituting part with respect to a template with the rack. CONSTITUTION:A rack 40 is formed to the outer periphery of the base part of an inner peripheral holder 18 and a pair of bevel gears 41 are meshed with the rack 40. Support shafts 42 are attached to the bevel gears 41 and handles 43 are attached to the support shafts 42. The inner peripheral holder 18 can be moved in a mold opening and closing direction by the bevel gears 41 and the rack 40 by rotating the handles 43. For example, when a stamper 16 is replaced, mounting bolts are removed to detach an outer peripheral holder 17 and, when the bevel gears 41 are rotated by rotating a pair of the handles 43, the rack 40 moves toward a fixed mirror surface plate l and the inner peripheral holder 18 can be easily detached from a movable mirror surface plate 10 and the stamper 16 can be replaced. |
