INJECTOR FOR APPARATUS FOR INJECTION MOULDING OF PLASTIC MATERIALS FOR THE PRODUCTION OF TRANSPARENT OR SEMI- TRANSPARENT AESTHETIC COMPONENTS FOR MOTOR VEHICLES FOR EXAMPLE LAMP LENSES AND A INJECTION MOULDING APPARATUS

摘要

The present invention relates to an injector in apparatuses for injection-molding plastic materials for the production of transparent or semitransparent decorating components such as lenses for automotive lamps, and an injection molding apparatus. To this end, a nozzle terminal (8) of the injector has a ring nut and a tip having each distal end portion. One of the distal end portions is connected to a gate of a molding cavity, operates along with a shutter terminal (10) of a valve pin (9), while the total thickness (2A) of a cross-section is less than or equal to the total thickness (B) of a cross-section of the shutter terminal (10) of the valve pin (9).
