Abstract:
A mold opening and closing mechanism for a section of an I.S. machine comprisingat least one mold half having vertical cooling air passage means,a mold carrier assembly including carrier/insert means for supporting said at least one mold half and horizontal axially extending shaft means connected to said carrier/insert means,a housing including means for supporting said horizontal axially extending shaft means for axial displacement so that said carrier/insert means can be axially displaced between retracted and advanced positions,said housing additionally including first and second vertically extending duct means, said first and second vertically extending duct means each having, at the upper end thereof, a sleeve,a manifold assembly includinga manifold frame including a plenum including a portion for overlying each of said at least one mold half, the at least one plenum portion having downwardly opening exit means,a spacer secured beneath said manifold frame and having vertically extending spacer hole means communicating with the downwardly opening exit means of each of the at least one plenum portion for delivering cooling air from the plenum to the vertical cooling air passage means of the at least one mold half,said manifold including a pair of horizontally facing cylindrical inlet holes,a pair of cylindrical tubes each having a first end slidingly received by one of said cylindrical holes, andfirst and second elbow means for connecting a second end of each of the cylindrical tubes to said sleeves so that cooling air from the ducts will be delivered to the pair of tubes,each of said pair of cylindrical tubes having a length selected so that the first end of each of said cylindrical tubes will be in the corresponding inlet holes as said carrier/insert means is displaced between the retracted and advanced positions.
