Abstract

An actuating device for adjusting at least one valve needle of an injection molding apparatus with a hot runner manifold that has disposed thereon at least one hot runner nozzle with at least one valve needle extending there-through which may control the melt flow through the hot runner nozzle. The actuating device has a support plate that is connected to the at least one valve needle and movable in a first direction relative to the hot runner manifold. The actuating device further includes a reciprocating device for moving the support plate in the first direction relative to the hot runner manifold, wherein the reciprocating device includes a slider mechanism and an actuation drive that is connected to a trigger device for generating a linear motion, wherein the slider mechanism has at least one thrust rod that is disposed in a second direction at an angle relative to the first direction.
