Claim 18:
19. 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) further 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 around the drive axis (Y),
a linear travel converter (15) interconnected between the rotor (250) and a valve pin (800) in an arrangement that converts rotation movement of the rotor to linear movement (XX) of the valve pin (800),
a heated manifold (300) that generates manifold heat,
the linear travel converter (15) comprising a converter housing (120) comprised of one or more converter walls (120r, 120rb, 120rc, 120ri, 120ro, 120a) that are comprised of a heat conductive material, the converter walls (120r, 120rb, 120rc, 120ri, 120ro, 120a) being mounted to the heated manifold (300) in an arrangement such that the manifold heat is communicated to the converter walls (120r, 120rb, 120rc, 120ri, 120ro, 120a),
a converter tube or channel (125) surrounded by and in intimate heat conductive contact with the heat conductive material of one or more of the converter walls (120r, 120rb, 120rc, 120ri, 120ro, 120a),
a source of heat absorptive fluid (125F) sealably interconnected to the converter tube or channel (125) in an arrangement such that the heat absorptive fluid (125f) is routed through the converter tube or channel (125) in a flow that absorbs the manifold heat communicated to the converter walls.
