Abstract: A press for adjusting and inspecting molds is disclosed, which comprises a vertically movable slide and two bolsters provided on the lowermost position of the opposite sides of the slide. The slide has a coupler provided on either side. Each bolster has a coupler provided on either end. The couplers of each bolster can be coupled to the respective couplers of the slide by first coupling one of them to the corresponding coupler of the slide such that the bolster can be swung relative thereto. The slide includes a bolster inverter, which consists of a piston-cylinder assembly or the like for swinging a bolster about its end detachably coupled thereto, and an inverter orientation controller for turning the end of the bolster inverter toward the respective bolsters. Two molds are disposed on the opposite sides of the lowermost position of the slide, and either one of them can be adjusted and inspected when desired.
