Abstract

Injection-moulding device (1) with a feed plate (3), in which at least one flow channel (4) for a flowable material is formed, with at least one needle valve nozzle, through which the flowable material can be fed in continuation of the flow channel to a separable mould insert, with at least one shut-off needle (20), at least a portion of which passes through the flow channel in a longitudinally displaceable manner and which can be brought by means of a drive into an open position and a closed position, and with a guide bush (30) for leading the shut-off needle (20) through and sealing it. The guide bush has a region which encloses the shut-off needle with a small amount of play and at least a portion of which lies in the flow channel. The region thereby has a contact surface for the flowable material, at least a portion of which lies in the flow channel. The region and the contact surface (44) are flowed around by flowable material on all sides.
