Abstract
A mold assembly includes a mold having a mold cavity defined by a mold surface having a three-dimensional shape and at least one opening for communication of fluid or vacuum to the mold cavity. A plenum base is mounted to the mold such that a chamber is defined between the plenum base and the mold, where the chamber is in communication with the at least one opening in the mold. A cooling plate is arranged in the chamber. A fluid passage is defined between the concentrically arranged outer tube and inner tube coupled to the plenum base. One fluid conduit extends through the inner tube and a first opening in the plenum base to the chamber. Another fluid conduit extends from the fluid passage through a side port in the outer tube and a second opening in the plenum base to the cooling plate.
