The invention relates to a device for charging the plasticizing unit of an injection-moulding machine, in which a filler support (10) comprising a stuffing cylinder (12), which is held by its upper rim in a retaining flange (13), is fixed to the screw cylinder (6). The upper rim of the stuffing cylinder (12), the retaining flange (13) and a brace plate (15), which is fixed to said retaining flange (13), share the same plane. Supporting pillars (16), which bear two mutually parallel displacement rails (17), are fixed to the retaining flange (13). A support plate (19) can be displaced on these displacement rails (17) between two positions, using sliding blocks (18). The support plate (19) bears a stuffing ram (22) comprising a hydraulic cylinder (20) and a storage container (21). A hydraulic control cylinder (23) allows the stuffing ram (22) and the storage container (21) to be alternately aligned flush with the stuffing cylinder (12). The invention aims to improve the access to the filler support (10) for cleaning during a material change. To achieve this, the stuffing cylinder (12) is coupled to the stuffing ram (22) and is raised upwards, allowing free access to the through channel which is located in the filler support (10).

L'invention concerne un dispositif pour charger l'unité de plastification d'une presse d'injection, où une tubulure de remplissage (10) avec un cylindre de bourrage (12) est fixée sur le cylindre à vis (6), le cylindre de bourrage étant inséré dans un collet de maintien (13) au niveau de son bord supérieur. Le bord supérieur du cylindre de bourrage (12), le collet de maintien (13) et un plateau d'appui (15) fixé sur ce dernier se trouvent sur le même plan. Sur le collet de maintien (13) sont fixés des montants (16) supportant deux rails (17) de positionnement parallèles. Un plateau support (19) peut être déplacé sur ces rails (17) entre deux positions par l'intermédiaire de blocs de glissement (18). Ce plateau support (19) porte un piston de bourrage (22) avec cylindre hydraulique (20) et réservoir (21). Un cylindre de réglage (23) hydraulique permet d'aligner alternativement le piston de bourrage (22) et le réservoir (21) sur le cylindre de bourrage (12). L'invention vise à faciliter l'accès à la tubulure de remplissage (10) pour son nettoyage lors d'un changement de matériau. A cet effet, le cylindre de bourrage (12) est couplé au piston de bourrage (22) et relevé, libérant ainsi l'accès au canal de passage qui se trouve dans la tubulure de remplissage.
