摘要

Injection device comprises a nozzle unit (2) and a safety device that is mounted on the nozzle unit and comprises a protective plate (6) that can move relative to the nozzle unit and is designed so that, when the nozzle unit is docked in the feed opening of a mold with the protective plate interposed, flow communication can be established with the injection nozzle (26). Independent claims are also included for: (1) safety device comprising a protective plate that that can move relative to a base element and has a nozzle system; (2) method for operating an injection device comprising a nozzle unit and a safety device comprising a protective plate that can move relative to the nozzle unit during docking and is spaced from the nozzle unit in a withdrawn state, where the nozzle unit and the protective plate form a flow communication in the docked state.
