Abstract

The invention relates to a device for thermoplastic material injection moulding. An injection longitudinal nozzle (13) arranged in the channel (15, 16, 17) of an injection matrix (1) is supplied by means of a distributor (18). The front end (74) of the nozzle (13) forwardly abuts against the collar (86) of the channel (15, 16, 17), whereas the rear end area (48) of the nozzle (13) is arranged in the longitudinal output channel (28) of a distributor (18) in such a way that it is longitudinally slidable therein and is mutually sealed therewith. Elastic means (100) presses the nozzle forwardly with respect to the distributor (18). Said invention is particularly suitable for slender nozzles.
