METHOD FOR COOLING HEATED MOLDS FROM A MACHINE FOR MOLDING CONTAINERS

摘要

Method for cooling heated molds from a machine for molding containers. The invention relates to a method for cooling heated molds from a machine (10) for molding containers from thermoplastic material by stretch-blow molding hot preforms using at least one pressurized fluid. Said cooling method is characterized in that it comprises, in order to cool said molds (18), at least one cooling step that involves selectively feeding at least one cooling fluid into the molding cavity (16) of at least some of the molding units (12) that, after the carousel (14) has been stopped in order to immobilize said molding units at least during said cooling step, are located in a predetermined cooling region in which said molding units (12) are in a closed position.
