Abstract:
1. An apparatus for producing a structure which includes a plurality of stems, each stem contiguous with at least two undercut segments spaced away from and overhanging the adjacent fenestrations of a common fenestrated base, with a plurality of said stems associated with each fenestration, said apparatus comprising: a molding axis; a first die including at least one first cavity with a second die including at least one core correspondent to said first cavity with a core end generally perpendicular to said axis, a plurality of second cavity walls, and a plurality of second interfacing walls; and means for engaging said first die with said second die to produce a product of a moldable material inserted therebetween; said first die and said second die configured so that when they are engaged along said axis, a segment of said core partially bypasses said cavity opening so that said first interfacing walls and said cavity end respectively interface with said second interfacing walls and said core end to effect a segmented gate partially divided by stem chambers, each said stem chamber enclosed by portions of said first and said second cavity walls and extending to a terminal chamber also enclosed by said first and said second cavity walls with an underside coincident with a segment of said second cavity walls on said core end, so as to effect a common cavity with at least one block-out and a plurality of contiguous stem chambers extending away from said common cavity at the edge of said block-out, each said stem chamber extending to a terminal chamber with an underside extending over said block-out; and wherein said first and second die cavities are configured to form said structure; thereby, filling said cavity with said moldable material and engaging said dies by said means produces said structure.
