Abstract

The injection nozzle (1) comprises an exit hole (IF) to inject a material (M) in an injection hole (7) of a mold (9). The nozzle is provided, inside itself, with a coupling member (3) suitable to open or close the exit hole (IF) and to couple or release a closing element (5) of the injection hole (7) of the mold in order to open or close it.
