Abstract
Embodiments of a mold for making a retaining wall blocks are disclosed. The mold enables blocks to be made more quickly by enabling separation of each block from the mold housing when the block is cured sufficiently to enable separation. Once separated, the block can be permitted to fully cure away from the mold housing, while the mold housing is re-used to produce one or more other blocks. In one embodiment, among others, the mold has a movable bottom tray and a mold housing with at least one door. The mold housing has an opening designed to receive and introduce a fabrication material, such as concrete, into the cavity. Once a block is sufficiently cured, it is separated from the mold housing on the tray through the at least one door, and a new tray is inserted in the mold housing to make another block.
