Abstract: An interface device between an injection tube and a mold provided with an injection hole, wherein the interface device includes a terminal element for an injection tube, with an end piece inserted into one end of the tube and a sealing ring that slides onto the tube, and a mechanism for holding and clamping the terminal element. The mechanism which is to be screwed into a mounting that is rigidly connected to the mold and is arranged around the injection hole, forms a seal between an injection end of the end piece and a sealing surface of the mold at the injection hole. The dismantlable assembly includes a screw-on socket that has a supporting surface for the sealing ring.

Abstract: 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).
