A needle valve nozzle (1) with injection mold (2) has a channel (11) for injection molding of flat workpieces form its narrow side. The channel (11) lies in the interior of the valve needle (10) belonging to the nozzle and extends over a partial longitudinal region of this valve needle (10). The channel (11) has an inlet (12) in the interior of the housing (6) of the needle valve nozzle (1) and at least one lateral exit (13) at an outlet before the free end (10a) of the valve needle (10) facing the injection mold (2), so that the open position of the needle valve nozzle provided for injection molding is reached by pushing the valve needle (10) with this exit (13) so far out of the housing (6) that the lateral exit (13) comes to lie at the level of the mold or cavity to be filled, while for the closed position, the valve needle (10) with this exit (13) can be retracted into the housing (6).
