Abstract
The invention includes apparatus for use in molding refractory material and is useful, for example, in molding bricks and other similar products. The apparatus includes a mold table supported by a plurality of vertical columns, the mold table being supported for translational movement on the columns. The apparatus further includes a mold box supported by the mold table, the mold box including at least one vertical mold cavity having opposite open ends. The apparatus also includes a plunger assembly supported below the mold and including at least one plunger having an end received in the mold cavity. A plunger assembly is also supported above the mold and includes at least one plunger receivable in the mold cavity, the plungers of the opposed plunger assemblies being functional to compress refractory material placed in the mold. To facilitate adjustment of the thickness of the molded products, the plungers are supported by a plurality of readily removable shims, variation of the number and thickness of the shims being functional to modify the relative positions of the plungers.
