Abstract:
1. Device for the production of molded parts, comprising first and second cross members, tie rods, a ring-shaped section, first and second support blocks, and a pressing module, wherein said first and second cross members are connected with one another by way of said tie rods, wherein said ring-shaped section accommodates said pressing module, wherein a first passage is disposed between said first support block and said second support block, wherein a distance between said first and second cross members relative to one another can be adjusted via said first support block and via said second support block, wherein the device further comprises a tool plate and a hydroforming tool having a compensator for compensation of process-pressure-induced bending of the tool plate, wherein the compensator comprises a first compensation plate that can be bent, under hydraulic control, in or counter to the process-pressure-induced bending direction of the tool plate, and wherein the first compensation plate has a depression for producing a hydraulic pressure cushion.
