Abstract
A mold assembly for forming concrete products comprises a plurality of partition plates spanning between pairs of end plates and forming one or more columns within a product mold matrix, where each of the partition plates have edge surfaces on each long end adjacent a respective one of the end plates and opposing faces along an expanse of the partition plate. A plurality of liners span between pairs of partition plates and form one or more rows within the product mold matrix, where each of the liners include edge surfaces on each long end adjacent a respective one of the partition plates, and buttons projecting from the edge surfaces of the liners configured to be received within complementary apertures formed through the faces of adjacent partition plates.

A mold assembly for forming concrete products comprising:
- a plurality of partition plates spanning between a pair of end plates and forming one or more columns within a product mold matrix, each of the partition plates having edge surfaces on each long end adjacent a respective one of the end plates and opposing faces along an expanse of the partition plate;
- a plurality of liners spanning between a pair of adjacent partition plates and forming one or more rows within the product mold matrix, each of the liners having edge surfaces on each long end adjacent a respective one of the partition plates;
- and
- buttons projecting from the edge surfaces of the liners configured to be received within complementary apertures formed through the faces of adjacent partition plates.
A method for manufacturing wear plates within a mold assembly, comprising the steps of:
- prior to heat treatment of the wear plates, machining buttons on edge surfaces of a first set of wear plates;
- after heat treatment, forming apertures through faces of a second set of wear plates that are configured to be arranged perpendicular to the first set within a mold assembly so that the apertures are aligned with the buttons of the first set of wear plates;
- and
- further machining the buttons to within a prescribed diameter of the apertures.
A wear plate for use in a mold assembly of a type used for concrete molded products, the wear plate comprising:
- a rigid plate having opposing faces defining a thickness of the wear plate therebetween and opposing edge surfaces on each end of the rigid plate spanning between the faces;
- and
- one or more buttons formed from the rigid plate and extending from each of the edge surfaces, the buttons having a width approximately equal to the wear plate thickness, with the buttons being configured to be received within apertures formed within the mold assembly so that the wear plate can be integrated into the mold assembly and define mold cavities therein.
A mold assembly for forming concrete products comprising:
- a first set of wear plates spanning between end plates and dividing the mold assembly into a plurality of mold cavity columns;
- and
- one or more buttons extending from edge surfaces of the wear plates and configured to be received within apertures formed within the end plates so that the wear plates can be integrated into the mold assembly and define mold cavities therein.
