摘要:
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.

Each mold half is held by means of a mold half holding mechanism which can be driven so as to pivot in a reciprocating manner about a common vertical hinge column by means of a vertical shaft (6; 7), which is mounted in a rotatable manner in a frame (2) of the glass forming machine (1), and by means of first intermediate members. Each shaft (6; 7) is connected via a lever mechanism (8; 9) to a common drive shaft which can be pivoted in a reciprocating manner by means of a drive element (19), which can be moved linearly in a reciprocating manner, of a drive (20) and by means of second intermediate members (18). The drive element (19) can be mounted on a nut (26) and secured against rotating about a longitudinal axis (39) of the drive element (19) by means of a guide device (32). The nut (26) is in engagement with a spindle (33). The spindle (33) is mounted in an axially fixed, rotatable manner and can be driven rotationally in a reciprocating manner by means of the drive (20).

A moving mechanism for moving a baffle (16), funnel or blowhead. A support (14) for the member is pivotally mounted on a first horizontal axis (20) on an arm (18) which is mounted to turn about a second horizonal axis (22) to move the member between operative and out-of-the-way positions. Driving means (24) is operable to turn the arm about the second horizontal axis and orientation means (42) maintains the member in a constant orientation during movement of the arm.

A glassware forming machine has at least three individual side-by-side molds at both the blow and the blank side of the machine, which molds are upwardly open and adapted to be closed by a blowhead or baffle depending upon which side of the machine (blank or blow) that the molds are at, that is for either forming the final article at the blow side or the preliminary parison at the blank side. Three blowheads are disclosed for use at the blow side of a machine, and are retained in a carrier arm for limited vertical movement in order to accommodate variations in height of the tops of the individual molds. Two links extend laterally through slots in the blowhead retainers, and a bellcrank lever interconnects these links to the carrier itself so that upon closing contact made between one of the three blowheads and its associated mold, downward movement of the other two blowheads will occur thereby equalizing the closing forces between all three blowheads and their associated molds.

A multi-section blow molding machine for the manufacture of hollow glassware has in each section a parison mold for each pair of blow molds. The blow molds are disposed below and on opposite sides of the center of oscillation of a neck ring arm carrying rotatable neck rings and arranged so that the mold or molds on one side are open when those on the other side are closed. The molds and neck ring arm are interconnected to oscillate together in opposite directions between lockable positions 180.degree. apart. The parison mold and associated feed and plunger means are movable in and out of operative position below and above the neck ring arm respectively, and operate in timed relation thereto. The open blow molds are spray cooled during the blowing cycle as well as during oscillation of the neck ring arm between its locked positions. In the closed blow molds, the blowing is continued simultaneously with the spray cooling to further cool the molded articles prior to release to a take-out conveyor.

摘要:
An I.S. Machine is provided wherein the blow molds are closed to a slightly cracked location whereby applied cooling air can not leak into and pressurize the blow mold thereby damaging the parison during reheat. When reheat is completed, the blow molds are fully closed and the parison is transformed into a bottle by applying compressed air and/or vacuum.
