Abstract
A mold box for molding concrete products includes a pair of opposed substantially parallel end plates. A pair of opposed substantially parallel mounting brackets are positioned at opposite ends of the end plates and together with the end plates form a substantially rectangular mold box. A corner portion is defined adjacent the juncture of each mounting bracket with each end plate. At least one partition plate extends from one end plate to the other between the mounting brackets. An alignment pin is formed on the mounting bracket at each corner portion and an alignment bore coaxial with the pin is formed on the end plate. The bores are sized and positioned so that when each bore has its associated alignment pin therein the mold box assembly is sufficiently aligned to form molded products.
