A mold open and close mechanism for an I.S. glass forming machine comprising:
- a mold carrier for carrying at least one mold, the mold including two halves, with each mold half including a locating key;
- a support structure configured to support the mold carrier for linear displacement between mold open and mold closed positions;
- a drive mechanism connected to the mold carrier for displacing the mold carrier between the mold open and closed positions;
- and
- the mold carrier having a vertical front mounting face portion including for each mold half:
- a locating structure for locating a mold, the structure including a lower and an upper pair of lugs in a spaced apart relationship and defining a vertically extended T-shape slot configured to receive the locating key of a least one mold half, and
- a flat vertical face for transferring clamping forces to a carried mold, wherein the mold half is aligned vertically and horizontally in the mold carrier.
A mold open and close mechanism for an I.S. glass forming machine, the machine including a mold carrier for carrying a least one mold, a support structure configured to support the mold carrier for linear displacement between a mold open and a mold closed position, a drive apparatus coupled to the mold carrier for displacing the mold carrier between the mold open and closed positions, the mold open and close mechanism comprising:
- a vertical front mounting face portion defined on the mold carrier, the vertical front mounting face portion including for each mold:
- a locating structure for locating a mold, the structure including a lower and an upper pair of lugs in a spaced apart relationship and defining a vertically extended T-shape slot configured to receive a locating key of a least one mold half;
- a flat vertical face for transferring clamping forces to a carried mold, wherein the mold half is aligned vertically and horizontally in the mold carrier;
- and
- a vertical wedge member operatively coupled to the vertical front mounting face portion of the mold carrier and aligned with each mold, wherein the vertical wedge member is configured to selectively push against the mold.
