Abstract
Improved mechanism, for oleo-hydraulic presses, used, for example, in the compression molding of reinforced plastics and those formed by a movable upper element that slides in guide columns and a fixed lower element both related by said guide columns, characterized in that, for each guide column includes: a) a double-effect cylinder, defined by a chamber located in the upper separator and divided into two semi-chambers (c1), (c2) by a plunger portion provided in the own guide column; b) an outer circuit, with opening-closing means communicating with each other both semi-chambers and pushing means that pump fluid to one or other of the semi-chambers from an outer tank; so that the approach stroke of the movable upper element takes place by gravity, the two half-chambers (c1), (c2) communicating with each other; the work stroke takes place by pumping fluid in the semi-chamber (c1); the slow return stroke takes place by pumping fluid in the semi-chamber (c2), in both cases with communication between closed semi-chambers, and the fast return stroke takes place by pumping fluid into the semi-chamber ( c2) keeping both semi-cameras communicated with each other.
