Claim 28:
29. An injection molding system (1000) comprising an injection molding machine (500) that injects a flow of injection fluid (400) to a heated manifold (300) that distributes the injection fluid (400) to a flow channel that delivers the injection fluid to a gate (70) of a mold cavity (80), the injection molding system (1000) comprising:
an actuator (5) comprised of a rotor (250) having a drive axis (Y) and a driver (100, 200) interconnected to the rotor (250) adapted to drive the rotor rotatably around the drive axis, the rotor being interconnected to a valve pin (800) having a pin axis (X) in arrangement such that the valve pin (800) is drivable linearly along the pin axis (x),
the actuator having a housing (20) comprised of radial (20r, 20ri, 20ro, 20roa, 20rob, 20roc, 20rod) and axial walls (20a, 20ai, 20aue, 20ade) comprised of a heat conductive material,
the rotor and driver being supported within the chamber by the radial and axial walls (20r, 20ro, 20ri, 20roa, 20rob, 20roc, 20rod, 20a, 20ai, 20aue, 20ade),
an actuator tube or channel (25) surrounded by and in intimate heat conductive contact with the heat conductive material of one or more of the radial and axial walls (20r, 20ro, 20ri, 20roa, 20rob, 20roc, 20rod, 20a, 20ai, 20aue, 20ade),
a source (260) of heat absorptive fluid (25f) sealably interconnected to the tube or channel (25) in an arrangement such that the heat absorptive fluid (25f) is routed through the tube or channel (25) in a flow that absorbs heat from the one or heat conductive walls (20r, 20ro, 20ri, 20roa, 20rob, 20roc, 20rod, 20a, 20ai, 20aue, 20ade),
wherein the housing (20) is mounted in heat conductive communication with the heated manifold (300) such that manifold heat is absorbed by or communicated to the one or more radial and axial walls (20r, 20ro, 20ri, 20roa, 20rob, 20roc, 20rod, 20a, 20ai, 20aue, 20ade) of the housing, the heat absorptive fluid (25f) absorbing the manifold heat absorbed by or communicated to the one or more radial and axial walls (20r, 20ro, 20ri, 20roa, 20rob, 20roc, 20rod, 20a, 20ai, 20aue, 20ade) of the housing.
