Molds and processes that permit high-speed, mass production of retaining wall blocks having patterned or other processed front faces, as well as retaining wall blocks formed by such processes. The invention permits the front face of the block to be impressed with a pattern or otherwise directly processed, to allow the formation of pre-determined block front faces, while at the same time facilitating high-speed, high-volume production of blocks. Pre-determined front faces can include front faces having pre-determined patterns and textures, front faces having pre-determined shapes, front faces made from different material(s) than the remainder of the block, and combinations thereof.

What is claimed is: 1. A mold assembly for use in a block machine to form multiple pre-cured dry cast concrete blocks on each cycle of the block machine, each block having upper and lower faces, a front face, a rear face and opposed side faces, the mold assembly comprising: a plurality of mold cavi
What is claimed is: 1. A mold assembly for use in a block machine to form multiple pre-cured dry cast concrete blocks on each cycle of the block machine, each block having upper and lower faces, a front face, a rear face and opposed side faces, the mold assembly comprising: a plurality of mold cavities, each comprising: a plurality of side walls defining a mold cavity having an open mold top and an open mold bottom, a first of the side walls including a first converging side wall portion that is moveably mounted so that it is movable between a first molding position at an angle with respect to vertical so that the mold cavity is wider at its top than it is at its bottom when dry cast concrete is introduced into the mold cavity, and a second discharging position in which the bottom of the mold cavity is at least wide enough to allow a pre-cured concrete block to be discharged through the bottom of the mold cavity, wherein the first converging side wall portion extends across an entire distance of the mold cavity between two opposed side walls that are adjacent a second side wall; and a stripper shoe having a face that comprises a three-dimensional pattern for introduction into the mold cavity through the open top of the mold cavity to press the patterned face of the stripper shoe on dry cast concrete contained in the mold cavity, to impart a pattern to the front face of a pre-cured concrete block. 2. The mold assembly of claim 1 wherein a second of the opposed side walls, which is generally perpendicular to a first of the opposed side walls, includes an undercut adjacent the open mold bottom, and including a pallet having a surface that temporarily closes an entire open bottom of each of the mold cavities, the undercut of each of the mold cavities and a portion of the surface of the pallet defining a flange-forming subcavity configured to form a flange of the block in that mold cavity. 3. The mold assembly of claim 1 wherein the pattern of the face of each of the stripper shoes simulates natural stone. 4. The mold assembly of claim 3, wherein the stripper shoes include a flange surrounding a perimeter of the patterned face and the flange is arcuate so as to produce rounded edges on the front face of the concrete blocks. 5. The mold assembly of claim 2, wherein a remainder of the second of the opposed side walls with the undercut is substantially planar and extends substantially vertically. 6. The mold assembly of claim 1 wherein a second side wall of each mold cavity opposite the first of the side walls includes a second converging side wall portion which is opposite the first converging side wall portion and extends the entire distance across the mold cavity between the two opposed side walls that are adjacent the second of the side walls, and wherein the second converging side wall portion is moveably mounted so that it is movable between a first molding position at an angle with respect to vertical so that the mold cavity is wider at its top than it is at its bottom when dry cast concrete is introduced into the mold cavity, and a second discharging position in which the bottom of the mold cavity is at least wide enough to allow the pre-cured concrete block to be discharged through the bottom of the mold cavity. 7. The mold assembly of claim 6, wherein the converging side wall portions are pivoted near ends thereof adjacent the open mold top. 8. The mold assembly of claim 6, further including a mechanism for biasing each of the converging side wall portions to the first molding position. 9. The mold assembly of claim 8, wherein the mechanism for biasing each of the converging side wall portions comprises an air bag connected to each converging side wall portion. 10. The mold assembly of claim 6, wherein each of the converging side wall portions includes a substantially planar surface facing the mold cavity. 11. A mold assembly for use in a block machine to from multiple pre-cured dry cast concrete blocks on each cycle of the block machine, each block having upper and lower faces, a front face, a rear face, opposed side faces, the mold assembly comprising: a plurality of mold cavities, each comprising: a plurality of side walls defining a mold cavity having an open mold top and an open mold bottom, a first of the side walls including an undercut adjacent the open mold bottom; a second of the side walls, which is generally perpendicular to the first side wall, including a first converging side wall portion that is moveably mounted so that it is movable between a first molding position at an angle with respect to vertical so that the mold cavity is wider at its top than it is at its bottom when dry cast concrete is introduced into the mold cavity, and a second discharging position in which the bottom of the mold cavity is at least wide enough to allow a pre-cured concrete block to be discharged through the bottom of the mold cavity, wherein the first converging side wall portion extends across an entire distance of the mold cavity between two opposed side walls that are adjacent the second side wall; a third of the side walls, which is opposite the second side wall, including a second converging side wall portion which is opposite the first converging side wall portion and extends the entire distance across the mold cavity between the two opposed side walls that are adjacent the second side wall, and wherein the second converging side wall portion is moveably mounted so that it is movable between a first molding position at an angle with respect to vertical so that the mold cavity is wider at its top than it is at its bottom when dry cast concrete is introduced into the mold cavity, and a second discharging position in which the bottom of the mold cavity is at least wide enough to allow the pre-cured concrete block to be discharged through the bottom of the mold cavity; and a stripper shoe having a face that comprises a three-dimensional pattern for introduction into the mold cavity through the open top of the mold cavity to press the patterned face of the stripper shoe on dry cast concrete contained in the mold cavity, to impart a pattern to the front face of a pre-cured concrete block. 12. The mold assembly of claim 11 wherein the pattern of the face of each stripper shoe simulates natural stone. 13. A mold assembly according to claim 11, wherein each stripper shoe includes a flange surrounding a perimeter of the patterned face. 14. The mold assembly of claim 13, wherein the stripper shoe flange is arcuate so as to produce rounded edges on the front face of the concrete block. 15. The mold assembly of claim 11, wherein a remainder of the first of the side walls with the undercut is substantially planar and extends substantially vertically. 16. The mold assembly of claim 11, wherein the converging side wall portions are pivoted near ends thereof adjacent the open mold top. 17. The mold assembly of claim 11, further including a mechanism for biasing each of the converging side wall portions to the first molding position. 18. The mold assembly of claim 11, wherein the mechanism for biasing each of the converging side wall portions comprises an air bag connected to each converging side wall portion. 19. The mold assembly of claim 11, wherein each of the converging side wall portions includes a substantially planar surface facing the mold cavity.
