Abstract (en)
The nozzle head (1) for a spray head for applying and distributing a release agent onto the pressure or injection molds, comprises a housing jacket (3), in which a processing space (4) is formed, where the processing space has a nozzle module arranged between a funnel-shaped opening (5) and a piston (6), and a port formed at the housing jacket to led the opening over the nozzle module, and a port formed at the housing jacket to fed a compressed air to the opening. The piston protrudes into the nozzle module along its side turned towards the funnel-shaped opening side in a closed position. The nozzle head (1) for a spray head for applying and distributing a release agent onto the pressure or injection molds, comprises a housing jacket (3), in which a processing space (4) is formed, where the processing space has a nozzle module arranged between a funnel-shaped opening (5) and a piston (6), and a port formed at the housing jacket to led the opening over the nozzle module, and a port formed at the housing jacket to fed a compressed air to the opening. The piston protrudes into the nozzle module along its side turned towards the funnel-shaped opening side in a closed position. An entrance opening formed in the housing jacket locks for the release agent and unlocks for the release agent in an opened position. The nozzle module is detachably fixed into the housing jacket. The surface of the nozzle module turned to the piston has a hardened surface, and is provided with a titanium nitride coating. The diameter of the nozzle of the nozzle module is 1.5 mm. The nozzle head is made of ceramic, stainless steel or hardened steel. An independent claim is included for a spray head.
