PROBLEM TO BE SOLVED: To provide a switchgear causing no increase of sliding resistance between a link pin and a bush, no abrasion or galling during molding operation, and capable of securing a stable mold-opening/closing operation and of maintaining the accuracy thereof even in a high-speed mold-closing operation, and to provide a molding device and a method for use of the switchgear.SOLUTION: A switchgear 30 comprises: a pressure receiving platen 32; a fixed platen 33 supporting one mold 15; a movable platen 34 supporting the other mold 16; a toggle mechanism 37; a drive unit 38; and a control unit 50. The toggle mechanism 37 has a plurality of links 41a to 41c and a plurality of pins 39a to 39e, and at least one of the pins 39c to 39e has a through-hole 51. The control unit 50 has a control part controlling to stream a refrigerant into the through-hole 51 of the pins 39c to 39e during the molding operation including molding by using a mold 14.SELECTED DRAWING: Figure 1 |
