Abstract
The mold includes an outer wall that has a plenum chamber defined in an inner surface thereof and at least one passage for communicating the plenum chamber with an external coolant conduit. The mold further includes a liner that is secured to the inner surface of the outer wall. The liner has a number of slots defined in an inner wall thereof which, together with the outer wall, define a number of passages for transporting coolant to cool the liner during operation of the mold. A recess intersecting at least one of the slots is provided in the inner wall of the liner. A restrictor plate is situated in the recess, and serves to strategically reduce the cross-section of selected slots in order to achieve the desired coolant flow profile among the slots. The mold may further include a velocity plate that is positioned between the plenum and the transition portion to limit an opening by which coolant may flow between the plenum and the transition portion. The velocity plate has a tapered cutout portion defined in a side thereof that faces the transition portion. The combined effect of the cutout portion and the transition portion is to define a flowpath that induces a substantially con…
