Abstract
An apparatus includes a cooling pin to slidably extend from a frame and to be inserted into an injection molded article. The cooling pin is hollow to allow for flow of cooling fluid through the cooling pin. The cooling pin has a hole to be in fluid communication with a source of vacuum to draw cooling fluid within the injection molded article into the cooling pin. The cooling pin has a first position with respect to the frame, the first position to allow flow of cooling fluid through the hole. The cooling pin has a second position with respect to the frame, the second position to shut off flow of cooling fluid into the cooling pin.
