Cooling injection mold

An apparatus for molding a plastic material comprising:

• a mold body including a first surface, at least a portion of the first surface being curved to mold a plastic part and a second surface opposite said first surface, said second surface following said first surface for providing a substantially uniform thickness between said first and second surfaces;
• a back plate removably coupled with said mold body;
• a contour on said back plate for forming at least one fluid communication path between said second surface and said removably back plate contour for enabling fluid to contact said second surface, said at least one fluid path having a uniform thickness between the second surface and back plate contour along said at least one fluid path for minimizing the temperature variance across said first surface.

An apparatus for injection molding a thermoplastic material comprising:

• an injection mold body including a first surface adapted to mold a thermoplastic part, said mold first surface has one or more curved portions and a second surface opposite said first surface;
• a back plate removably coupled with said injection mold body;
• a raised contour on said back plate for forming at least one fluid communication path between said second surface and said removable back plate contour for enabling fluid to contact said second surface, said at least one fluid path having a uniform thickness between the second surface and back plate contour along said at least one fluid path for minimizing the temperature variance across said first surface.
