OG exemplary drawing
 
1. An injection molding apparatus comprising:
a heated manifold that receives injection fluid from an injection molding machine and distributes the injection fluid to a flow channel that delivers the injection fluid to a gate of a mold cavity,
an actuator controllably drivable by electric power having a drive axis and a driver adapted to controllably drive a valve pin along a linear path of travel, the valve pin being adapted to vary rate of flow of the injection material to and through the gate,
the driver receiving electrical energy or power from an electrical drive,
the electrical drive comprising an interface that receives and controllably distributes electrical energy or power in controllably varied amounts during the course of an injection cycle to the driver,
the actuator having a housing,
the electrical drive being housed within or by the housing or being mounted on or to the housing,
the housing and the electrical drive being mounted on, to or in close proximity to the heated manifold,
the apparatus including a cooling device disposed between the heated manifold and the housing,
the cooling device being adapted to substantially isolate or insulate at least the electrical drive from substantial communication with heat emanating or emitted from the heated manifold.
