Beschreibung
Zusammenfassung:	The invention relates to an interface device (1) between an injection tube (2) and a mold (3) provided with an injection hole (4), characterized in that the interface device (1) comprises a terminal element for an injection tube, comprising an end piece (5a, 5b) inserted into one end of the tube (2) and a sealing ring (6) that slides onto the tube, and a means (7, 8) for holding and clamping the terminal element. Said means (7, 8), which is to be screwed into a mounting (9) that is rigidly connected to the mold and is arranged around the injection hole (4), forms a seal between an injection end of the end piece and a sealing surface (10, 11) of the mold at the injection hole. The dismantlable assembly comprises a screw-on socket (7) that has a supporting surface (7a) for the sealing ring (6). L'objet de l'invention est un dispositif interface (1) entre un tube d'injection (2) et un moule (3) pourvu d'un trou d'injection (4) caractérisé en ce qu'il comporte une terminaison pour tube d'injection, comportant un embout (5a, 5b) s'insérant dans une extrémité du tube (2) et une bague d'étanchéité (6) enfilée autour du tube, et un moyen (7, 8) de maintien et de serrage de la terminaison, adapté à se visser dans un support (9) solidaire du moule et disposé autour du trou d'injection (4) et à assurer une étanchéité entre une extrémité d'injection de l'embout et une surface (10, 11) d'étanchéité du moule au niveau du trou d'injection, l'assemblage démontable comportant une douille à visser (7) pourvue d'une face (7a) d'appui sur la bague d'étanchéité (6).
