Abstract

Closing system for presses, characterized by: one or several hydraulic jacks intended to move the movable plate of the press, which carries a part of the mold, to make it execute said opening and closing races; at least two pairs of articulated bars, movable from a position in which the bars form an angle to each other at a position in which said bars are aligned and increase their total length, and vice versa; means for moving said pairs of bars from one to another position, the bars of each pair being arranged so that, in the alignment position, they exert a strong thrust on the moving plate, to provide the closing force of the mold in the phase of closing, pressing with one end said movable plate and, with the other end, a fixed plate of the frame of the press.
