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) comprising a supporting structure (14), which is connected to a fixed support of the machine (1) in a releasable manner and supports 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) located on opposite sides of the plane (P) of symmetry, and actuating means (28, 36, 37; 28, 37, 59) for rotating the supporting and actuating arms (19) and moving the half-molds (6) between a closed position and an open position.
