ABSTRACT:
A closing device in a hydraulic injection molding machine includes at least one pressure cylinder unit for building up locking pressure and a drive cylinder mounted in the pressure piston of the pressure cylinder unit for closing the injection mold. The drive cylinder is arranged concentrically relative to the central axis of the pressure cylinder unit. A support element for the pressure cylinder is jutted out by at least one cylinder of the mold closing unit on the side opposite to the stationary mold carrier, the cylinder being connected to the support element and stationary as a result thereof. The support element forms thereby a single piece with the stationary cylinder of the mold closing unit that is connected to the support element. This provides a space-saving structure that meets precision requirements for the production of injection molded parts.
