摘要
A moulding mechanism for a glassware forming machine comprises a mould (30; 170, 172), a supporting plate (31; 174) supporting at least a bottom portion of the mould, a plenum chamber (32, 34; 176, 177) extending downwardly from the supporting plate and arranged to supply air at substantially equal pressure to passages (33, 175) in the supporting plate which communicate with cooling passages (50; 192, 194) in the mould, and a piston and cylinder assembly (36, 38; 178, 180) operable to raise and lower the supporting plate (31; 174). At least a portion of the plenum chamber (32, 34; 176, 177) is formed as a tubular piston rod (34; 177) extending upwardly from the piston (36; 178) of the piston and cylinder assembly.
