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.

What is claimed: 1. A system for manufacturing an uncured concrete block using a dry-cast manufacturing process, comprising: a mold box including a pair of side walls, a pair of side plates fixedly fastened to the pair of sidewalls so that the sidewalls and side plates do not substantially move, an
What is claimed: 1. A system for manufacturing an uncured concrete block using a dry-cast manufacturing process, comprising: a mold box including a pair of side walls, a pair of side plates fixedly fastened to the pair of sidewalls so that the sidewalls and side plates do not substantially move, an open top side and an open bottom side, defining an open interior region; a division plate spanning the open interior region to define a plurality of separate mold cavities within the open interior region; a movable end liner disposed within two or more of the plurality of separate mold cavities; a hydraulic cylinder located within the open interior region and operably coupled with the movable end liners to selectively shift the movable end liners between a first position and a second position; and a push member connected to the movable end liners; a push bar connected to the push member; and a connecting member extending from the hydraulic cylinder connected to the push bar. 2. The system of claim 1, further comprising a tubing system connected to the hydraulic cylinder. 3. The system of claim 2, further comprising a pumping unit connected to the tubing system. 4. The system of claim 3, wherein the pumping unit is electronically controlled. 5. The system of claim 1, wherein the movable end liner is provided with a face having a three-dimensional texture. 6. The system of claim 1, wherein the movable end liner is provided with a tapered face. 7. The system of claim 1, further comprising a second end liner, opposing the first end liner, disposed within two or more of the plurality of separate mold cavities. 8. A system for manufacturing an uncured concrete block using the dry-cast manufacturing process, comprising: a mold box having a generally vertically extending internal perimeter surface that maintains a generally vertical orientation during the manufacturing process, the mold box comprising: a pair of side walls, a pair of side plates fastened to the pair of sidewalls so that the side plates do not move with respect the side walls during the manufacturing process, an open top side and an open bottom side, wherein the pair of sidewalls, the pair of side plates, the open top and the open bottom define an open interior region having a fixed volume that is maintained throughout the manufacturing process, and; a division plate spanning the open interior region to define a plurality of separate mold cavities within the open interior region; a movable end liner disposed within two or more of the plurality of separate mold cavities; at least one actuator device disposed in the open interior region; a push member connected to the movable end liners; a push bar connected to the push member; and a connecting member extending from the at least one actuator connected to the push bar. 9. The system of claim 8, wherein the at least one actuator device includes a hydraulic cylinder. 10. The system of claim 8, further comprising a second movable end liner disposed, opposing the first end liner, disposed within two or more of the plurality of separate mold cavities. 11. The system of claim 10, further comprising a second actuator device operably coupled with the second movable end liner to selectively shift the second end liner. 12. The system of claim 11, wherein the first and second movable end liners are each provided with a face having a three-dimensional decorative texture whereby the faces impart a mirror image of the three-dimensional decorative texture to opposing sides of the uncured concrete block. 13. The system of claim 8, further comprising a compression head including a shoe, the shoe presenting a face having a three-dimensional decorative texture whereby the face imparts a mirror image of the three-dimensional decorative texture to a surface of the uncured concrete block. 14. A system for manufacturing an uncured concrete block using the dry-cast manufacturing process, comprising: a mold box including a pair of generally vertically oriented side walls, a pair of generally vertically oriented side plates, an open top side and an open bottom side defining an open interior region, the pair of side walls and pair of side plates fastened to each other so that during a manufacturing cycle they maintain their respective generally vertical orientations and the open interior region does not change in size or shape; a division plate spanning the open interior region to define a plurality of separate mold cavities within the open interior region; at least one movable end liner operably disposed within the two or more of the plurality of separate mold cavities; means for selectively shifting the end liners between a first position and a second position disposed in the open interior region; a push member connected to the movable end liners; a push bar connected to the push member; and a connecting member extending from the push bar to the means for selectively shifting the end liners.
