Method and a machine for the production of hollow glassware articles

Abstract

A method and a machine for the production of hollow glassware articles, by the blow-and-blow, press-and-blow, press-and-blow paste mold and direct-press processes in a glassware forming machine including single or multiple machine sections each having single or multiple-cavity, comprising: forming a parison in an inverted orientation, into a blank mold and a first transferable and open-able neck ring mold held by an inverting apparatus having a first and a second diametrically opposed arms, each arm holding a transferable and open-able neck ring mold; inverting the parison held by the first transferable and open-able neck ring mold, by rotating the first arm 180° to an upright orientation at an intermediate station, while the second arm with a second transferable and open-able neck ring mold is simultaneously placed at the parison forming station; transferring the first transferable and open-able neck ring mold holding the parison in an upright orientation, from the intermediate station, to a blow mold station, by a transference apparatus; releasing the first parison into a blow mold, and turning back the first transferable and open-able neck ring mold empty to the first arm of the inverting apparatus, at the intermediate station to be placed again at the parison forming station by rotating the first arm additional 180°, completing a 360° turn, while the second arm reaches to the intermediate station; blowing the parison into a blow mold to form a finished article; and transferring the finished article in an upright orientation, once the blow mold is opened, by a take out apparatus, to place it at a dead plate or at a carrying conveyor.

       168 . A molding apparatus for using as a blank mold or blow mold in glassware forming machines having single or multiple forming cavities, of the type including a blank mold forming station, an intermediate station, and a blow forming station, by the blow-and-blow process, press-and-blow wide mouth or narrow neck process, press-and-blow paste mold process and direct press, comprising:
 a mold per cavity, each mold being comprised by two mold halves to be assembled opposed face to face, both forming a cavity for forming a parison or a finished glassware article, each mold halve having a holding flange to be mounted on a mold holding mechanism mounted in turn on an apparatus support frame at the glassware article forming machine, at a blank mold “zero-line” or blow mold “zero-line”, and a plurality of axial passages axially passing through said mold halve for directly cooling the mold halves;   a mold holding mechanism mounted on a blank mold support frame or on the mechanism support frame, at the blank mold “zero-line” or blow mold “zero-line”, holding the mold halves by their holding flange and including:   a mounting bracket to be mounted on the opening and closing mechanism; a first and a second arms pivotally mounted on the mounting means in a hinged arrangement;   mold holders held by the first and second arms in which the blank mold or blow mold halves are held by their holding flange;   an equalizing mechanism in which are mounted the mold halves, comprising an equalizing beam, mounted on first and second arms of the mold holding mechanism; a first single mold holder mounted in said equalizing beam, in which it is respectively mounted a mold halve; a dual mold holder also mounted in said equalizing beam, in which are mounted two mold halves; and a first corresponding opposed single mold holder also mounted in said equalizing beam in which is respectively mounted a mold halve and a dual mold holder also mounted in said equalizing beam, in which are mounted two mold halves so that the mold halves can be uniformly closed with a similar closing force;   cooling means connected in fluid communication to the axial passages of the mold halves for cooling the mold holding mechanism, including a two-halves cooling box including nozzles placed at a fixed height only for the blank mold, or at an adjustable height in the blow mold, for directing cooling fluid into the axial passages of the mold halves, said cooling box is slide coupled on a sliding platform of a “T” shaped sliding valve of a power and fluid feeding system of the machine, mounted on the apparatus support frame, and maintained in sealed contact by a spring of said “T” shaped sliding valve, providing a communication of the cooling fluid during the whole path of the opening and closing operation of the mold; and   an opening and closing mechanism in which the mold holding mechanism is mounted, for closing the mold halves, for receiving a molten glass gob or a parison, and open it once the parison or a glassware article has been formed.
