Abstract (en)
[origin: WO2016051299A2] A press for the hot moulding of pieces, in particular hollow pieces made of brass or aluminium, comprises a fixed structure (10) defining a reaction plate (12), an upper mould-holder (16), a lower mould-holder (22), and a floating cushion (30) to which is operatively connected the lower mould-holder (22). The upper mould-holder is fixed to a movable slide (14). The press further comprises a plurality of reaction cylinders (40) connected to a hydraulic pressurisation circuit (50), said reaction cylinders being operatively interposed between the lower mould-holder (22) and the reaction plate (32) and being suitable to exert a progressive reaction cylinder reaction force that opposes the opening the opening of the half-shells. The floating cushion and the reaction cylinders are arranged in such a way that the overall reaction force at the opening of the half-shells is given by the sum of the progressive cushion reaction force with the progressive cylinder reaction force.
