The invention relates to a closing device in a hydraulic injection molding machine. The closing device has at least one pressure cylinder unit (10) for building up locking pressure and a drive cylinder (20) mounted in the pressure piston (13) of the pressure cylinder unit for closing the injection mold. The drive cylinder (20) is arranged concentrically relative to the central axis (m- m) of the pressure cylinder unit (10). A support element (62) for the pressure cylinder (10) is jutted out by at least one cylinder (62a) of the mold closing unit on the side opposite to the stationary mold carrier, said cylinder being connected to the support element (62) 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 said support element (62). This provides a space-saving structure that meets precision requirements for the production of injection molded parts.

L'invention concerne un dispositif de fermeture monté sur une machine de moulage par injection à fonctionnement hydraulique, qui comporte au moins un ensemble cylindre de compression (10), qui sert à établir la pression de maintien, et un cylindre d'entraînement (20), qui est logé dans le piston de compression (13) de l'ensemble cylindre de compression et sert à la fermeture du moule de moulage par injection. Le cylindre d'entraînement (20) est disposé concentriquement par rapport à l'axe central (m-m) de l'ensemble cylindre de compression (10). Un élément d'appui (62) destiné à l'ensemble cylindre de compression (10) est mis en saillie sur le côté opposé au porte-moule fixe, à l'aide d'au moins un cylindre (62a) de l'ensemble de fermeture de moule, lequel est relié à l'élément d'appui (62) et, ainsi, fixe, cet élément d'appui ne formant qu'une seule pièce avec le cylindre de l'ensemble de fermeture de moule relié à cet élément d'appui (62) et fixe. On obtient ainsi une structure de faible encombrement qui satisfait aux exigences de précision relative à la production de pièces moulées par injection.
