ABSTRACT:
An injection molding nozzle (1) for plastic with at least two outlet openings (2) facing toward different sides and directed oppositely is not constructed as an open injection molding nozzle but has a respective closure needle (5) in the outlet openings (2), and a drive is also provided for displacing the closure needles (5) at least into the closing position. Thus a cold plug at the end of the outlet openings (2) facing a mold (3) can be avoided, independently of whether the closure needles completely close these outlet openings (2) at their mouth (6) or still leave a minimum gap.
