1. An injection molding tool through which a melt flows, having
a. a nozzle plate which comprises a first through-hole in an axial direction, in which in the first through-hole an injection molding nozzle is arranged extending in the axial direction, and
b. a cavity plate which comprises at least one cavity half into which a second through-hole, which is arranged in the cavity plate and coaxially with respect to the first through-hole, opens, wherein
c. a nozzle bushing, which encloses the injection molding nozzle at least in regions in the assembled state, is arranged in the second through-hole, wherein
d. the nozzle bushing is operatively connected to the cavity plate and/or the nozzle plate by an operative connection means, wherein
e. the nozzle bushing and the operative connection means are operatively connected to one another at least in the axial direction,
wherein the operative connection means
includes a flange plate which comprises a central opening in which the nozzle bushing is arranged, wherein the flange plate is fastened to the nozzle plate and/or the cavity plate in the axial direction by means of one or more screws, or
includes a threaded bushing which comprises a central opening in which the nozzle bushing is arranged, wherein the threaded bushing is screwed to the nozzle plate and/or the cavity plate in the axial direction by way of a threaded connection.
