Actuator cooling apparatus and method
First Claim
1. An injection molding apparatus comprising a clamp plate mounted to a mold in spaced relationship, a heated manifold, an actuator comprising a housing body, and a cooling device that cools the actuator, wherein the manifold is disposed between the clamp plate and the mold and the housing body of the actuator is mounted in thermally conductive communication with the manifold,the cooling device comprising:
- a heat transmitter comprising a distal arm or member and a proximal base or member mounted in heat conductive contact to the housing body of the actuator,the distal arm or member being mounted to the proximal base or member via a spring loadable interconnection disposed between the proximal base or member and the distal arm or member such that the spring loadable interconnection can exert a spring load between the proximal base or member and the distal arm or member,characterized in that;
the proximal base or member has an engagement surface and the distal arm or member having one or more complementary engagement surfaces, the engagement surface and the complementary engagement surface being adapted to be disposed in sliding contact with each other for transmitting heat from the proximal base or member to the distal arm or member,the clamp plate, the mold, the manifold, the actuator and the heat transmitter being assemblable together in an arrangement wherein the spring loadable interconnection is loaded urging the distal end surface of the distal arm or member into compressed engagement with the clamp plate at least when the clamp plate, the mold, the manifold, the actuator and heat transmitter are assembled and the manifold is heated to an elevated operating temperature.
