complex moulds for a trainer of glassware for cyclic operation

摘要

The assembly comprises at least one mould (1) forming a cavity (2) for a glass article and provided with at least one base (3) and two side walls (5), each of which is movable from a first position in which it is in contact with the base to define the said cavity and a second position in which it allows the article to be removed; each of the said side walls includes a first duct section (19) which defines a first air flow path having a substantially radial direction with respect to the axis of the mould and into which open mould cooling air channels (7, 8), and the base comprises a second duct section (20) which defines a second air flow path also having a substantially radial direction and which opens into the first duct section when the side walls are in the first position and which is in communication with a source (22) of compressed air.
