Abstract

La présente invention porte sur une machine hydraulique pour lubrifiant qui permet de graisser une pluralité de cylindres hydrauliques courts qui génèrent la force de blocage du moule du mécanisme de serrage du moule raccordé à une pompe de unique de lubrifiant de façon à amener le lubrifiant vers chaque cylindre hydraulique court indépendamment et à éviter de nombreux problèmes tels que ceux se présentant sur des conduites longues, des problèmes de perte dans les tuyaux, un ralentissement de vitesse et une longue durée d'acheminement imputable au mode d'alimentation centrale du lubrifiant dans lequel tous les cylindres hydrauliques courts partagent une pompe commune de lubrifiant. En outre, la pompe de lubrifiant est pourvue d'un élément de stockage et peut-être montée tout à côté des cylindres hydrauliques courts afin de graisser des circuits fermés et les cylindres hydrauliques courts. Tous les circuits sont indépendants et séparés les uns des autres sans s'influencer lorsqu'ils utilisent une source d'énergie commune et fonctionnent de manière synchrone. Il n'y a ainsi dans la transmission de pression du lubrifiant ni fuite d'huile, ni pollution, la pression est maintenue sur une longue durée et ce système répond aux exigences de réduction du temps de fonctionnement. Si le moule d'ouverture et de fermeture utilise une commande mécanique ou une commande hydraulique, on peut éliminer la station de pompage hydraulique qui est onéreuse, ce qui réduit évidemment les coûts.
