A BACKFLOW CHECK DEVICE FOR A PLASTICISING SCREW OF AN INJECTION MOULDING MACHINE, AN INJECTION MOULDING MACHINE, AND USING METHOD OF A BACKFLOW CHECK DEVICE

摘要

the present invention, the front end (3), the pressure ring 4 and the distal end (3) and a check ring 5 can be arranged movable relative to the pressure ring (4) and each check-ring (5) and at least for the at least one insert member (7) disposed at the distal end (3) is formed in one of the guide path 6, the front end (3) or a check-ring (5), disposed parallel to the wall relative to the direction of movement (V) of at least one of the guide path 6, the check ring 5 8 and the check has a wall (9) disposed to be inclined with respect to the direction of movement (V) of the ring (5), at least one insert member (7) is equivalent to extend parallel to the parallel extending portion (10, 11, ) in the non-return device (1) for the plasticizing screw (2) of an injection molding machine having, in addition to any present in (6) guide the front end (3) at least one flow path for the molten plastic material (12 relates 12 ') for non-return device for an injection molding machine having a plasticizing screw. ;
