Abstract:
1. A metal casting system comprising: a first mold backing structure having a first mold backing structure plate that forms a first mold cavity first planar surface and having a second mold cavity second planar surface opposing the first mold cavity first planar surface, the first mold cavity first planar surface having a first mold cavity first framing portion that forms a first mold backing structure first surface and a first mold cavity first edge portion; a second mold backing structure having a second mold backing structure plate that forms a second mold cavity first planar surface and having a second mold cavity first framing portion that forms a second mold backing structure first surface that is removably attachable to the second mold cavity second planar surface and that forms a second mold cavity first edge portion; a first mold facing structure having a first mold cavity second planar surface, wherein the first mold backing structure first surface is removably attachable to the first mold cavity second planar surface; and a means for removably attaching the first mold backing structure first surface to the first mold cavity second planar surface and for removably attaching the second mold backing structure first surface to the second mold cavity second planar surface wherein, when the first mold backing structure first surface is attached to the first mold cavity second planar surface, the combination of the first mold cavity first planar surface, the first mold cavity second planar surface, and the first mold cavity first edge portion forms a first mold cavity and a first mold cavity first open edge for providing a flow of a molten metal into the first mold cavity, and wherein, when the second mold backing structure first surface is attached to the second mold cavity second planar surface, the combination of the second mold cavity first planar surface, the second mold cavity second planar surface, and the second mold cavity first edge portion forms a second mold cavity and a second mold cavity first open edge for providing a second flow of the molten metal into the second mold cavity.
