The present invention relates to a roto-linear mechanism for a glassware forming machine adapted to be connected to a funnel-holding arm, a shutter arm, an arm for a blowing head or a similar mechanism, to simultaneously perform an axial and radial movement to each of such arms from a first position to form glass articles to a second position outside the forming process thereof.

The present invention relates to mold cooling method and system for a glass container forming machine that includes at least one mold holder including mold halves that are movable between a closed mold position for forming the glass article and an open mold position for releasing said article, each of the mold halves having axial passages for cooling each of the mold halves. A support structure having a fixed upper support section and a movable support section. Means for providing a cooling flow are coupled in coincidence with a series of openings in the movable support section. A cooling flow distributor located above the movable support section, the cooling flow distributor having a lower section in coincidence with each of the openings of the movable support section for the passage of the cooling flow and, a upper section in coincidence with each of the axial passages of each of the halves of each mold, the cooling flow distributor being movable between the closed mold position and the open mold position.

A mold system is provided for use in a glass container mold assembly that includes a base, a first plunger containing cylinder having a first cross-sectional area configured and sized to fit upon the base, and a male mold merger movable between a retracted and extended positioned that is configured tor insertion into a gob of molten glass to form an interior cavity in the gob to form a parison capable of be big blown into a glass container. The mold system comprises an alignment cylinder coaxially coupled to the plunger containing cylinder and having a second cross-sectional area larger than the first cross-sectional area of the plunger containing cylinder for accommodating and receiving a male mold member having a cross-sectional area too large to be accommodated by the first cross-sectional area of the plunger containing cylinder. The alignment cylinder includes an interior passageway.
