Abstract A mold assembly is disclosed for making a reinforcing panel structure including female and male molds with each mold having a base surface with four sided projections extending upwardly from the base surface to a raised surface. The projections of each mold are spaced from the next adjacent projection in that mold in a first direction a distance equal to the dimension of the projection in that direction plus a predetermined dimension which is double the thickness of the rib of the panel and with each projection spaced from the next adjacent projection in that mold in a second direction perpendicular to the first direction a distance equal to the dimension of the projection in that second direction plus a predetermined dimension which is double the thickness of the rib of the panel. Each of the projections have embossments thereon. When the molds are mated the projections of one mold are disposed in the spaces between the projections of the other mold and are spaced therefrom by the predetermined dimensions or the thickness of the ribs and the embossments on the projections engage the base surface of the opposite mold.
A mold assembly for making a reinforcing panel structure, said mold assembly comprising; a female mold and a male mold, each of said molds having a base surface with four sided projections extending upwardly from said base surface to a raised surface, each of said projections of each mold being spaced from the next adjacent projection in that mold in a first direction a distance equal to the dimension of the projection in said first direction plus a predetermined dimension and spaced from the next adjacent projection in that mold in a second direction transverse to said first direction a distance equal to the dimension of the projection in said second direction plus a predetermined dimension, said projections of said female mold being disposed in the spaces between said projections of said male mold and spaced from said projections of said male mold by said predetermined dimensions when said female and male molds are mated, said raised surface of said projections of said respective molds being spaced from said base surface of the opposite mold when said molds are mated, and an embossment on each of said raised surfaces smaller in dimension than each respective projection, said embossments of said respective molds engaging said base surface of the opposite mold when said molds are mated.

A mold assembly for making a reinforcing panel structure, said mold assembly comprising; a female mold and a male mold, each of said molds having a base surface with four sided projections extending upwardly from said base surface to a raised surface, each of said projections of each mold being spaced from the next adjacent projection in that mold in a first direction a distance equal to the dimension of the projection in said first direction plus a predetermined dimension and spaced from the next adjacent projection in that mold in a second direction transverse to said first direction a distance equal to the dimension of the projection in said second direction plus a predetermined dimension, said projections of said female mold being disposed in the spaces between said projections of said male mold and spaced from said projections of said male mold by said predetermined dimensions when said female and male molds are mated, said raised surface of said projections of said respective molds being spaced from said base surface of the opposite mold when said molds are mated, and an embossment on each of said raised surfaces smaller in dimension than each respective projection, said embossments of said respective molds engaging said base surface of the opposite mold when said molds are mated.
