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 AN INJECTION MOULDING APPARATUS

摘要

A nozzle terminal of an injector comprises a tip and a ring nut having respective distal ends one of which is configured so as to be coupled with a gate of a moulding cavity, it cooperates with the shutter terminal of the valve pin of the injector, and it has an overall thickness in cross-section which is equal to or less than that of the cross-section of the shutter terminal of the valve pin.

1. An injector for apparatus for injection moulding of plastic materials for production of transparent or semi-transparent aesthetic components for motor vehicles, including a nozzle having a nozzle terminal defining a flow path for injected plastic material and a valve pin having a shutter terminal and axially displaceable between a receded opening position and an advanced closing position of the nozzle terminal, wherein said nozzle terminal comprises an inner tubular element or tip and an annular ring nut arranged externally and coaxially to the tip, and an tip and the ring nut have respective distal ends, and
wherein one of said distal ends of the tip and ring nut: is configured so as to be coupled with a gate of a moulding cavity, cooperates with said shutter terminal of the valve pin, and has an overall thickness in cross-section which is equal to or less than that of the cross section of the shutter terminal of the valve pin.
