1. A hot runner injection molding apparatus comprising:
a machine injection unit including a machine nozzle; a first machine platen, fixed to a machine base, a second machine platen which is movable with respect to the first machine platen; a hot runner manifold having an inlet melt channel and a plurality of output melt channels a plurality of hot runner nozzles associated with the manifold output melt channels; a movable closure elements carrier plate or valve pin plate connected to a plurality of valve pins or to a plurality of closure elements, wherein the valve pins or closure elements are associated with the hot runner nozzles; at least one moving actuator device that moves the closure elements carrier plate or the plate with the valve pins between at least two positions, whereupon the valve pins are displaced between the at least two positions relative to a valve seat of the hot runner nozzle to control the amount of a molten material injected into a mold cavity through the manifold and the hot runner nozzles; wherein the first machine platen being adjacent the machine nozzle of the injection unit and wherein the first machine platen includes a multi-portion chamber or an inner cavity within which the hot runner manifold, the movable carrier plate or valve pin plate and the actuator device are at least partially arranged.
