System for aiding in the replacement of a mould of a moulding unit of a machine for manufacturing containers

A system for aiding in the replacement of a mold intended to be used for the replacement of at least one mold of a molding unit equipping a machine for manufacturing containers by the forming, by means of at least one fluid under pressure, of a preform made from a plastic material having been thermally conditioned beforehand, the system comprising:

• said molding unit comprising at least:
• two mold carriers which are mounted so as to be movable between at least one open position and one closed position of the unit, and
• a mold comprising at least two molding elements configured to be brought together in order to occupy a joined position, or configured to be separated in order to occupy a disjoined position,
• inside the molding unit, each of the at least two molding elements of the mold being configured to be secured in a detachable manner to one of the associated mold carriers by associated securing means, the associated securing means being configured to be controlled when the molding unit is in the closed position between at least one securing position and one release position;
• and
• at least one device for transporting the mold forming a transportable unit subassembly, the transportable unit subassembly being a joined mold, the said transport device comprising
• handling means comprising
• at least one principal holding device configured to interact with a first portion of the joined mold to bring together the at least two molding elements of the mold to form the joined mold and to maintain the joined mold as joined, the first portion being accessible to the principal holding device when the molding unit is in the closed position, and
• at least one secondary holding device configured to interact with a second portion of the joined mold which is accessible when the molding unit is in the open position, the at least one secondary holding device being mounted so as to be movable between at least one retracted position and one advanced position.
