Injection molding nozzle for plastic with at least two outlet openings

摘要

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.
