Actuating device for locking needles in injection molds with needle locking nozzles

Abstract

Actuating device (4) for shut-off needles (24, 86) in injection molds (2) with needle shut-off nozzles (81), with at least one movable lifting element (6) on which at least two shut-off needles (24, 86) can be fixed, so that the shut-off needles (24, 86) can be brought into an open and a closed position by a movement of the lifting element (6), characterized in that the shut-off needles (24, 86) are each attached in a needle receptacle (20) with a relative position adjustable along their longitudinal direction, wherein the needle receptacles (20) are arranged slidably along their central axes in the lifting element (6) and are each forced into the closed position by a spring (50).
