Abstract:
A system and method for manufacturing an uncured concrete block using the dry-cast manufacturing process includes a mold box having a pair of side walls, a pair of side plates, an open top side and an open bottom side defining a mold cavity. One or more end liners are disposed within the mold cavity and are selectively shiftable within the mold cavity with hydraulic cylinders between a first position and a second position. The end liners can be provided with a three-dimensional textured face to impart a decorative face to a side surface of the concrete block formed in the mold or can also provide blocks with a tapered face when disposed in the second position while the mold is filled with concrete. Before the block is stripped from the mold, the end liners are returned to the first position, so that the side surfaces are not damaged as the block is released.
