Abstract
Official abstract text for this publication.
Apparatus for injection-moulding of plastic materials comprising a hot runner ( 1 ), at least one injector ( 2 ) including a nozzle mobile within which is a valve pin ( 3 ) driven by a rotary electric motor ( 4 ) and an associated transmission including a screw-and-nut assembly ( 10 ) for converting the rotation of the shaft ( 5 ) of the electric motor ( 4 ) into a translation of the valve pin ( 3 ). At least the rotary electric motor ( 4 ), and the screw-and-nut assembly ( 10 ) are set parallel alongside one another.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for injection-moulding of plastic materials comprising a hot runner, at least one injector including a nozzle, within which a valve pin is axially movable, and actuator means for governing axial displacement of the valve pin between a closing position and an opening position to enable flow of fluid plastic material under pressure from the hot runner into a mould cavity, wherein the actuator means include a rotary electric motor and a transm…
