An I.S. machine has a blankmold which is open at the top and includes inner and outer annular top sealing surfaces. Associated with the blankmold is a baffle including a body having a cup shaped portion closed with a vertical cylindrical bore open at the bottom, an annular bottom sealing surface for sealingly engaging the blankmold outer annular top sealing surface, and a top having a hole. A tubular sleeve communicates with the hole and extends vertically upwardly from the top of the body. A piston has a cylindrical head including a top surface, a cylindrical sealing surface and an annular bottom sealing surface having a plurality of radial notch means across the bottom thereof. A tubular rod extends vertically upwardly from the top surface for slidable displacement in the tubular sleeve, and a collar is secured to the top of the rod. A spring located between the collar and the cup shaped portion urges the cylindrical head vertically upwardly to a position whereat the cylindrical head top surface engages the top of the cup shaped portion. The collar is pneumatically displaced vertically downwardly at a high pressure to bring the cup shaped portion annular surface into sealing engagement with the blankmold outer annular sealing surface. The pressure is then reduced so that a predetermined distance separates the cylindrical head annular bottom sealing surface and the blankmold inner annular sealing surface so that settle air can be introduced into the mold, and then the pressure is again raised to the high pressure for parison formation.

In a blank mold side of an I.S. glass container forming machine, mold cooling air flows from a fixed source through a supply conduit to a plenum that underlies and oscillates with a mold-carrying arm. Cooling air from the source flows upwardly through the supply conduit and then into a hollow member that has an inlet portion telescopically received in an outlet of the supply conduit. The hollow member, which is capable of oscillating motion in a horizontal plane with respect to the supply conduit, has a horizontally-facing outlet with an annular part-spherical bearing surface, and an annular part-spherical bearing is positioned in the part-spherical bearing surface for pivoting motion in a vertical plane of the part-spherical bearing with respect to the hollow member. A cooling air inlet tube has an inlet end telescopically received in the part-spherical bearing. The outlet end of the cooling air inlet tube is non-telescopically received in a part-spherical bearing surface of the plenum. In a blow mold side of an I.S. glass container forming machine, cooling air flows from a fixed source through a supply conduit to a plenum that underlies and oscillates with a mold-carrying arm without any substantial change in the direction of air flow therethrough. A cooling air inlet tube having an outer element, an inner element telescopically positioned within the outer element and a spring to resiliently bias the inner element and the outer element away from one another is provided to accommodate changes in distance between the source and the plenum that occur because of oscillating motion of the mold-carrying arm.

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.

A mold opening and closing mechanism includes an aligning mechanism which has a horizontal mounting plate including a number of vertical openings for the number of molds, that is supported by a pair of spaced vertical uprights secured to the section frame top surface. A plurality of aligning cylinders are located in the vertical openings in the horizontal mounting plate and move parallel with the mold holder motion. Each cylinder includes surfaces configured to mate with the clamping surfaces of the mold holders. The axis of one of the aligning cylinders is held but not clamped at the theoretical centerline so it can move to the actual centerline when the mold holders are located at the advanced clamped closed position. A position transducer is mounted parallel with the mold holder motion to sense movement of the axis of one of the aligning cylinders and a computer receiving positional data from the transducer compares the theoretical centerline with the actual centerline determined from the data and defines a displacement offset for the displacement program to align the mold holders to the theoretical centerline.

The central body is formed by an even number of complementary sectors at least equal to four, radially and simultaneously movable between an active position for molding the item from said paraison in which the sectors are laterally applied against one another, and a passive position for stripping the item in which said sectors are laterally spaced apart from one another.

The method allows fabricating a bottle mold having dissimilar metal inserts embedded in regions where the bottle mold is most subject to attack by hot glass, and has a glass contact surface with refined grain size. To fabricate the bottle mold, rough castings are made by pouring cast-iron into a composite mold having dissimilar metal insert blanks fixably positioned therein. The dissimilar metal insert blanks become embedded in the cast-iron matrix to form rough dissimilar metal inserts in the rough casting. The composite mold has regions formed by metal chills that are partially embedded in a sand mix. The chills and the exposed surfaces of the rough dissimilar metal inserts define a cavity surface of the rough casting, which is subsequently machined to provide the glass contact surface of the bottle mold. The chills refine the grain size of the cast iron at the glass contact surface.
