ABSTRACT:
A needle seal nozzle assembly for a plastics injection machine, injection mold or hot-runner system, includes a housing defining a passageway for feeding a melt from an inlet to an outlet, with housing being formed by a first housing portion having one end facing the inlet, and by a second housing portion facing the other end of the first housing portion and having an interior forming part of the passageway. The first housing portion includes a substantially cylindrical tubular body which defines a fluid channel that forms another part of the passageway and is fluidly connected to the interior of the second housing portion. Received in fluidtight manner between the first and second housing portions is a slide for displacement between a first position in which a fluid flow through the outlet is cut and a second position in which the flow of melt is open through the outlet. The slide has one end formed with a sealing needle for regulating the fluid flow through the outlet and another nozzle-distant end which is acted upon by a drive mechanism for moving the slide between the first and second positions.
