The invention relates to a device for injecting material in a plastic state into a moulding cavity. The inventive device comprises a distributor (11) for said material in a plastic state and an injection nozzle (10) which is connected to the distributor (11) by a detachable connection means (31) and has a front surface (78) which is formed in such a way that it can become integral with the moulding cavity (2). In order to enable the front surface (78) to be positioned in such a way as to permit said integral connection when the nozzle (10) is assembled and re-assembled after dismounting, indexing means (49, 54, 57, 59, 90, 95, 99) are provided for the angular position of said front surface (78) in relation to the distributor, along with locking means (31, 85) fixing said front surface (78) in relation to the distributor (11) in a relative angular position which is imposed by the indexing means (49, 54, 57, 59, 90, 95, 99).
La présente invention concerne un dispositif d'injection de matière à l'état plastique dans une empreinte de moulage. Ce dispositif comporte un distributeur (11) de matière à l'état plastique et une buse d'injection (10) liée au distributeur (11) par un moyen de solidarisation amovible (31) et présentant une face frontale (78) conformée de façon à s'intégrer à l'empreinte de moulage (2). Pour assurer au montage et au remontage, après démontage, de la buse (10) un positionnement de la face frontale (78) permettant cette intégration, on prévoit des moyens (49, 54, 57, 59, 90, 95, 99) d'indexage de la position angulaire de cette face frontale (78) par rapport au distributeur (11) et des moyens de verrouillage (31, 85) fixant cette face frontale (78) par rapport au distributeur (11) dans la position angulaire relative imposée par des moyens d'indexage (49, 54, 57, 59, 90, 95, 99).
