20080209951 | GLASSWARE FORMING MACHINE MOLDS OPENING/CLOSING DEVICE - A mold of a glassware forming machine has a longitudinal plane of symmetry, and two half-molds movable between a closed position and an open extraction position by a powered mold opening/closing device, which has a fixed fastening and supporting structure, two mold-holders, and, for each mold-holder, a respective supporting and actuating arm hinged to the relative mold-holder to rotate about a movable hinge axis, and to the fixed structure to rotate about a fixed hinge axis; the fixed hinge axes being located on opposite sides of the plane of symmetry, and at such a distance from the plane of symmetry that, when the half-molds are in the closed position, the line intersecting the fixed axis and movable axis of each arm extends substantially parallel to the plane of symmetry. | 09-04-2008 |
20090025429 | MOLD ACTUATING AND COOLING ASSEMBLY FOR A GLASSWARE MOLDING MACHINE - In a glassware molding machine, the half-molds of a mold are moved between an open position and a closed position and cooled by an actuating and cooling assembly having a fixed supporting structure and, for each half-mold, a respective supporting and actuating arm fitted to the relative half-mold and hinged to the fixed supporting structure to rotate about a fixed hinge axis; each supporting arm internally defining a chamber communicating with a ring of cooling conduits formed through the half-molds, and the chamber having an inlet formed through an outer lateral wall of the supporting arm to receive cooling air from a compressed-air tank of the machine. | 01-29-2009 |
20110041559 | ASSEMBLY FOR OPENING/CLOSING MOLDS OF A GLASSWARE MOLDING MACHINE - A mold of a glassware molding machine has two half-molds movable between a closed molding position and an open extraction position by a mold opening/closing assembly, wherein two actuating arms, each fitted to a respective half-mold, are rotated about respective fixed hinge axes by an actuator assembly having a central linear actuator, and two lateral linear actuators located substantially on opposite sides of the central actuator; the actuators having respective movable members translating respectively along a central axis and two lateral axes parallel to one another and to the fixed hinge axes; and the central axis being located at a distance from a plane of the lateral axes. | 02-24-2011 |
20110314872 | GLASSWARE FORMING MACHINE MOLDS OPENING/CLOSING DEVICE - A mold of a glassware forming machine has a longitudinal plane of symmetry, and two half-molds movable between a closed position and an open extraction position by a powered mold opening/closing device, which has a fixed fastening and supporting structure, two mold-holders, and, for each mold-holder, a respective supporting and actuating arm hinged to the relative mold-holder to rotate about a movable hinge axis, and to the fixed structure to rotate about a fixed hinge axis; the fixed hinge axes being located on opposite sides of the plane of. symmetry, and at such a distance from the plane of symmetry that, when the half-molds are in the closed position, the line intersecting the fixed axis and movable axis of each arm extends substantially parallel to the plane of symmetry. | 12-29-2011 |
20150152892 | ACTUATING ASSEMBLY FOR MOVING AN OPERATIVE MEMBER OF A GLASSWARE FORMING MACHINE - In a glassware forming machine, an actuating assembly of an operative member has a tubular connecting body; a shaft for supporting the operative member coupled to the connecting frame to translate and rotate about a fixed axis thereof; a pneumatic jack for displacing the supporting shaft along the axis; a cam and tappet device for rotating the supporting shaft in opposite directions about the axis and having a chamber and a cam and tappet assembly housed in the chamber and lubricated by a lubricating liquid contained in the chamber; and a hydraulic device for stabilizing the motion of the shaft; the chamber and the hydraulic stabilizing device constituting part of a single closed hydraulic circuit for feeding a common lubricating and operative liquid to the cam and tappet device and to the hydraulic stabilizing device. | 06-04-2015 |
20150152893 | ACTUATING ASSEMBLY FOR MOVING AN OPERATIVE MEMBER OF A GLASSWARE FORMING MACHINE - In a glassware forming machine, an actuating assembly of an operative member has a connecting frame; a shaft for supporting the operative member coupled to the connecting frame to translate and rotate about a fixed axis thereof; a pneumatic jack for displacing the supporting shaft along the axis provided with a rod connected to the supporting shaft; a cam and tappet device for rotating the supporting shaft in opposite directions about the axis; and a hydraulic device for stabilizing the motion of the shaft; the rod having at least one hollow portion for housing the hydraulic motion stabilizing device. | 06-04-2015 |
