PURPOSE:To make high speed and space-saving possible by shifting in parallel a second parallel linkage mechanism by a first parallel linkage mechanism, and performing open and close of an opening and closing body via a holding member. CONSTITUTION:A molding mold 27 wherein polyurethane liquid is injected is shifted to a mold clamping position by a carriage, and a roller 33 attached to an upper mold is held between holding rods 18, 18 of a holding member 3, so that a motor 19 positively rotates, and thus, the linkage arms 4, 5 of a first linkage mechanism 1 angularly moves in a counterclockwise direction as fulcrums of axes 7, 8 in order to move in parallel the linkage arms 9, 12 of a second parallel linkage mechanism 2. Therefore, since the holding member 3 is moved circularly, at the same time, revolves as fulcrum of an axis of 15, there never occur jamming or the like between the holding roller 3 and roller 33, and thus, the upper mold 30 of the molding mold 27 can be mold-clamped smoothly. |
