Abstract

L'outil de moulage (1) comprend: - un moule mobile entre une position ouverte et une position fermée, - une cale de maintien (22) d'un élément de revêtement (6) mobile par rapport à une première partie de moule (8) entre une position écartée et une position de maintien, - un dispositif de déplacement de la cale de maintien (22) comprenant au moins une tige (26) mobile par rapport à un corps (28), ladite tige (26) définissant avec ledit corps (28) une première chambre d'actionnement (30), - un dispositif de commande du dispositif de déplacement. Le dispositif de déplacement est relié à une source de gaz comprimé (32), le dispositif de commande comprenant au moins une première valve d'entrée (42) interposée entre la première chambre d'actionnement (30) et la source de gaz comprimé (32).The molding tool (1) comprises: - a mold movable between an open position and a closed position, - a holding shim (22) of a covering element (6) movable relative to a first mold part ( 8) between a separated position and a holding position, - a device for moving the holding wedge (22) comprising at least one rod (26) movable relative to a body (28), said rod (26) defining with said body (28) a first actuation chamber (30), - a device for controlling the movement device. The displacement device is connected to a source of compressed gas (32), the control device comprising at least a first inlet valve (42) interposed between the first actuation chamber (30) and the source of compressed gas ( 32).
