ABSTRACT:
A mold box assembly for forming molded concrete products includes a pair of opposed substantially parallel end plates joined at both ends by a pair of opposed substantially parallel mounting brackets. A plurality of partition plates extend between the end plates to define a plurality of substantially identical cavities for forming molded products. A slot is formed along the inside of each end plate substantially along the length thereof. Tabs which extend from opposing ends of each partition plate include a stud transversely mounted on the end plate using ring nuts. The opposing tabs and studs of each end plate are received in opposing end plate slots. End liners are bolted to the inside surface of each end plate over the studs on each side of each partition plate with the ring nuts bearing against the surface of the end liner.
