DETAILED DESCRIPTION OF THE INVENTION A gob of molten glass is available from I.S.
S. Formed in the parison at a blank station (workpiece station) of a section of the machine. The blank station comprises a pair of opposing drive assemblies 10 each having a housing 11 secured to a section frame or box 12 by suitable fasteners 13.
(Only one of them is shown for clarity),
A mechanism for opening and closing a mold (molding mold) is provided. The housing 11 includes a vertical ball screw 1 for driving a pair of nuts 15 connected to the left end of the corresponding link 16.
4 is supported. The right end of the link is connected to a yoke 24 via a horizontal shaft 22 (FIG. 2),
It is interconnected with the carrier 25 via a vertical axis (not shown).

The gob is formed in a blank mold having a pair of opposing blank mold halves 26. Each of the blank mold halves is supported by one or more inserts 27 supported by a carrier 25. The carrier 25 is fixed to a pair of round shafts 28 slidably received in suitable bearings 29. Carrier 2
5 between the advanced position (FIG. 2), where the illustrated blank mold half engages the other blank mold half, and the retracted, mold open position where the carrier is close to the housing. It can be displaced by driving the ball screw 14 with an appropriate motor 30. Full details of such mold opening and closing mechanisms are disclosed in the above-mentioned US Pat. No. 5,833, incorporated herein by reference.
No. 0,254. Each of the mold halves has a series of vertical cooling holes 31 extending from its top to its bottom.

Cooling air is supplied through a pair of ducts 32 that extend from the bottom to the top of the housing 18 on each side of the housing 18. These ducts 32, which bend around a hole in the round shaft, terminate in a circular recess 34 at the top of the housing, which is formed by a suitable screw 40 (FIG. 1). Receiving the bottom of a cylindrical positioning sleeve 36 secured within a mounting collar 38 secured thereto. An “L” shaped elbow 42 is slidably received on each top portion of the locating sleeve 36. The "L" shaped elbow 42 includes a vertical portion 45 having a cylindrical base 44 that slides to a sleeve and an upper portion having a flat vertical surface 46 connected to a horizontally extending tube 48. ing.

Associated with each of the housings is a manifold 49 for providing cooling air to a set of blank mold halves supported by one of the carriers. Each free end of the tube (FIG. 1) has an oil-impregnated bronze bush 50.
Slidably received by the bronze bush,
The end cap 54 allows the frame 52 of the manifold 49
Are held adjacent to the corresponding inlets 51. These plenum inlets 51 communicate with an inlet 53 to a plenum chamber 60. Plenum chamber 60 produces three bottles each cycle. S. Three continuous and semi-annular portions 5 corresponding to the semi-circular tops of the three blank mold halves that may be present in the section
9. Each of the semi-annular plenum portions 59
It communicates with a semi-annular vertical slot 62 defined in a spacer 64. The spacer 64 is connected to the manifold by a number of screws (not shown) that extend upwardly through the spacer and into the manifold frame.
These semi-annular slots are located above a series of cooling holes 31 in the corresponding blank mold 10.

The manifold assembly (the interconnected manifold and spacer) sits on top of the insert 27 with limited movement relative to the carrier / insert by a pair of vertical screws 66. The vertical screw is
A manifold frame 52 secured to the top of the carrier
(So that the manifold assembly can be lifted to replace the blank mold half). A set screw 70 secures the elbow 42 to the sleeve 36 so as to accommodate limited and vertical adjustment. To accommodate a higher set of blank molds, the sleeve 36 and spacer can be replaced with a higher sleeve and spacer.

A bracket 80 is secured to each of a pair of vertical screws 66 just below the frame 52 of the manifold 49. Each of the brackets has a split clamp portion 81 that can be clamped to the associated screw by a fastener 82. A rotation shaft 84 to which the same cam 86 is fixed is rotatably supported by each pair of brackets. The rotation shaft can be rotated by the handle 88. The handle 88 is adapted to engage the cam end 89 slightly off-center with the bottom of the manifold frame from the first direction shown in FIG. The cam is fixed to one end of the rotation shaft so that the cam can be rotated up to this point. During the process of separating the manifold assembly (the bottom surface of the spacer 64) and the top of the blank mold, the manifold frame is sufficiently large that the operator lifts the blank mold away from the mold carrier insert. (A projecting portion 90 projecting downward is interconnected with a restraining portion 92 extending upward, and a button 94 restrains the upright flange 96). With the engagement line passing through the center, the manifold assembly is held in its fully raised position until the operator returns the horizontal handle to its initial vertical position.
