Abstract
Parisons of molten glass for subsequent moulding are molded in a mould cavity formed from one-piece lower portion (10), a dividable neck ring (14), and a dividable central mould portion (24). A gob of molten glass is introduced into a gov uide (58) so that the gob passes into the mould through the neck ring (14). A plunger guide (42) which serves to guide the plunger (26) through the neck ring (14) is introduced into the gob guide (58) and a plunger (26) is introduced into the plunger guide (42) so that the plunger enters the mould through the neck ring (14). During pressing of the glass, the guide (42) which serves to guide the plunger (26) through the neck ring (14) is pressed downwardly on to the neck ring (14). The guide (42) defines a sealing surface (54) of the neck portion (16) of the mould cavity.
