Title: COOLING PLATE ASSEMBLY FOR AN INJECTION MOLDING MACHINE
Abstract:
A cooling plate assembly includes (a) a cooling plate having a plate front surface; (b) an air channel extending within a thickness of the cooling plate; (c) a plate bore extending into the cooling plate from the plate front surface for providing fluid communication between the air channel and a cavity of a cooling tube mountable to the cooling plate; and (d) a valve within the plate bore. The valve is movable between a first position in which a first air flow passage extending within the plate bore is open for conducting air from the cavity to the air channel, and a second position in which the first air flow passage is obstructed to reduce air flow between the cavity and the air channel, and in which a second air flow passage extending within the plate bore is open for conducting air from the air channel to the cavity.
