<p>A mold (4) of a glassware forming machine (1) has a longitudinal plane (P) of symmetry, and two half-molds (6) movable between a closed position and an open extraction position by a powered mold opening/closing device (10; 50), which has a fixed fastening and supporting structure (14), two mold-holders (18), and, for each mold-holder, a respective supporting and actuating arm (19) hinged to the relative mold-holder to rotate about a movable hinge axis (20), and to the fixed structure (14) to rotate about a fixed hinge axis (23); the fixed hinge axes (23) being located on opposite sides of the plane (P) of symmetry, and at such a distance (D) from the plane (P) of symmetry that, when the half-molds (6) are in the closed position, the line (25) intersecting the fixed axis (23) and movable axis (20) of each arm (19) extends substantially parallel to the plane (P) of symmetry.</p> |
