A mold for glassware forming machine includes a pair of mold segments (14) each having a central portion and laterally spaced edge portions (54) adapted to be brought together at the edge portions to form a mold cavity (16). A coolant shell (68) is externally mounted over the central poriton of each mold segment to form a cooling cavity (58) between the coolant shell and the central portion of the mold segment, and the coolant shells do not extend into the edge portion of the mold segments. Coolant passages (60) separate from the cooling cavities extend axially through the edge portions of the mold segments to facilitate cooling the edge portion in use.

La présente invention a trait à un moule pour une machine de formation d'articles en verre comportant une paire de segments de moule (14) dont chacun comprend une portion centrale et des portions de bord à espacement latéral (54) adaptés pour être assemblés au niveau des portions de bord pour former une cavité de moule (16). Une enveloppe de fluide caloporteur (68) est monté à l'extérieur sur la portion centrale de chaque segment de moule pour former une cavité de refroidissement (58) entre l'enveloppe de fluide caloporteur et la portion centrale du segment de moule, et les enveloppes de fluide caloporteur ne s'étendent pas dans la portion de bord des segments de moule. Des passages de fluide caloporteur (60) distincts des cavités de refroidissement s'étendent en direction axiale à travers les portions de bord des segments de moule pour faciliter le refroidissement des portions de bord en cours d'utilisation.
