ABSTRACT:
A molding assembly includes a mold body, an insert block, and a cooling channel. The mold body has first and second surfaces which are opposite to each other, and a peripheral surface interconnecting the first and second surfaces. The mold body further has a plurality of die cavities, a plurality of runners, and a recess opening at the first surface. The recess extends from the first surface toward the second surface, and ends at a recess bottom surface disposed away from the first surface. The insert block is fitted within the recess and has an inner surface confronting the recess bottom surface, an outer surface opposite to the inner surface, and a side wall interconnecting the inner and outer surfaces. The cooling channel is confined by the recess bottom surface of the recess and the inner surface of the insert block.
