A backflow prevention device for an injection molding machine includes a screw tip having a tip end, a central body member connected to the tip end, a thrust ring at a rear end of the body member, and a mounting end for attachment to a plasticizing screw, A locking ring is arranged at a distance to the body member to define an annular gap and is axially movable between an open position, in which a first sealing surface rests against a shoulder of the tip end, allowing passage of material, and a closed position, in which a second seating surface rests against a shoulder of the thrust ring, prohibiting entry of material. Disposed in the annular gap coaxial to the locking ring is at least one mixing element in the farm of a circular ring which has circumferential bores in spaced- apart disposition for axial material transport.
