Abstract

A distributing arrangement for a pressurized cooling fluid, especially air, for cooling a forming tool of a machine for forming thermoplastic material, especially molten glass, wherein the forming tool includes at least one split mold including mold segments which are respectively mounted on mold segment holders for movement therewith relative to one another and each of which is provided with a plurality of fluid channels for the flow of the pressurized of fluid channels for the flow of the pressurized cooling fluid therethrough, comprises a fluid distributing box including for each of the mold segments at least two branch channels individually communicating with at least one of the fluid channels when the distributing box is mounted on the mold segment holder. The branch conduits can either directly communicate with the fluid channels across an interface formed by juxtaposed connecting and opposing surfaces of the distributing box and the associated mold segment, or a connecting box including a plurality of connecting channels may be interposed between the distributing box and the respective mold segment, in which case the interface is provided between the distributing and connect…
