A press for the hot moulding of pieces 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). A plurality of reaction cylinders (40) connected to a hydraulic pressurisation circuit (50) are operatively interposed between the lower mould-holder (22) and the reaction plate (32) and are suitable to exert a progressive reaction cylinder reaction force that opposes the opening the opening of the half-shells. |
