Injection moulding nozzle system for injection moulding machines

摘要

An injection-molding nozzle system comprises a temperable nozzle body (2) with a nozzle tip (3), a stroke limiter (8) limiting the opening stroke of sealing needle (6), which is displaceable in axially longitudinal manner by an actuating apparatus (7). The needle has a notch for pass-through of plastic mass in its transitional region to needle shaft. The nozzle tip has a cylindrical needle guide region for guiding the needle in any of its positions in radial direction. An independent claim is included for dismounting and remounting the injection-molding nozzle system of an injection-molding tool for plastic materials for cleaning the injection-molding nozzle and the needle.
