An injector nozzle for equipment for injection moulding of plastic materials has a nozzle tip (4) with an internal hollow element (5) and an external hollow element (6), which are connected to the body (1) of the injector nozzle in an independent way and defined between which is a space of mutual separation (11) . The internal hollow element (5) and the external hollow element (6) have respective axial portions (5c, 6a) in contact with one another, without, however, preventing the internal hollow element (5) from being screwed to and unscrewed from the body (1) of the injector nozzle independently of the external hollow element (6) . |
