A form for separating a concrete block and a method for separating a concrete block from the form. The formed concrete block remains stationary while the doors of the form are pulled away from the concrete block in order to more conveniently, efficiently, and safely obtain access to the formed concrete block for its removal.

An adjustable mold capable of making castings of various configuration is provided. The adjustable mold has an adjustable die with a core and an adapter, a protrusion, a cavity, and an outer portion with at least two sidewalls, at least two endwalls, and a base therebetween, which outer portion at least partially surrounds the adjustable die to thereby define a mold. During casting, molding material is poured in the mold and allowed to cure to make a casting. The adapter is replaceable to enable castings of multiple configurations to be cast suing the adjustable mold.

A block, block system and method of making a wall block. A block with multiple embodiments of a visually exposed surface having three dimensional shaped areas and three dimensional angular valleys or joints that can be used to construct a patio, wall, fence or the like; the multiple embodiments creating a more random and natural appearance. A mold box having a moveable liner and a stripper shoe that impart three dimensional shaped areas and three dimensional angular valleys or joints onto an exposed surface of a block. The moveable liner and stripper shoe also impart a parting line onto the exposed surface of the block.

A block, block system and method of making a wall block. Multiple block embodiments with multiple embodiments of a visually exposed surface having three dimensional shaped areas and three dimensional angular valleys or joints that can be used to construct a patio, wall, fence or the like; the multiple embodiments creating a more random and natural appearance.

A block reinforcement cage made from reinforcing material and adapted for loading within a machine during a block manufacturing process for molding a concrete U-wall construction block structure. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.
