Abstract

PURPOSE:To obtain a press which is capable of replacing a mold easily in the outside of the press, by providing an upper mold holding body, etc. on an adaptor plate being freely attachable and detachable to and from a slide, and also providing a cylinder device for a crank shaft, on a moving bolster. CONSTITUTION:When replacing torsional upper and lower molds 42, 26, at first, an upper mold holding body 44 is set on a lower mold holding body 27 by lowering a slide 15, and after that, a clamp of an adaptor plate 41 is detached, and the upper mold holding body 44, and the adaptor plate 41 are placed on a moving bolster 19. Subsequently, a clamp of the moving bolster 19 is detached, and when the moving bolster 19 is drawn out in the backward direction of a press by a moving oil pressure cylinder, the mold can be replaced easily and quickly in the outside of the press. Also, the mold is set into the press by reversing said procedures.
