1. An injection molding apparatus comprising:

  • a heated manifold that receives an injection fluid material from an injection molding machine, the heated manifold routing the injection fluid to a fluid delivery channel that extends and delivers the injection fluid material under an injection pressure to a gate of a mold cavity,an actuator comprising an actuator housing containing a drive member interconnected to a valve pin having a drive axis in an arrangement such that the valve pin is drivable along the axis between an upstream fully gate open position and a downstream gate closed position,the actuator housing being mounted on a surface of the heated manifold, the actuator housing being spaced a selectable distance forming a gap between the actuator housing and the heated manifold,the apparatus including one or more heat convectors each heat convector comprised of;

    a heat conductive leg disposed within the gap, the leg being isolated from direct metal-to-metal contact with the actuator housing and mounted in heat conductive communication with the heated manifold, thus serving to maintain the actuator in a relatively cool condition relative to the heated manifold, anda heat conductive arm extending distally away from the gap such that heat is conducted from the leg to the arm and away from the actuator housing.
