Abstract: Disclosed is a device for producing molded articles, comprising two cross members that are interconnected using tie rods. At least one cross member (11, 12) has an annular section accommodating a pressing module. At least one passage (30) is formed between at least two supporting blocks (3) which allow the distance between the cross members (11, 12) to be adjusted.

Abstract: A cylinder unit for mounting on a machine for the deformation of workpieces includes a cylinder block and a pressure plate which is arranged on the surface of the cylinder block which faces away from the fastening surface, wherein a plurality of pistons each having a spherically shaped head are mounted in the cylinder block. Mounted on each spherically shaped head of the pistons is a pressure piece which protrudes into a bore of the pressure plate and has a recess corresponding to the spherically shaped head of the pistons. A gap is provided between the outer diameter of the pressure piece and the inner diameter of the bore in the pressure plate. A pressure disc is arranged between the pressure piece and the pressure plate in the bottom of the bore of the pressure plate.

Abstract: A device for manufacturing formed parts by internal high pressure deformation. The device includes a housing composed of two tubular members which are placed one into the other and are connected by shrinkage, wherein the tool support unit is mounted in the concentric bore of the inner tubular member.
