Abstract
A method for manufacturing decorative concrete blocks for decorative garden walls is presented, along with a machine suitable for practicing the method.
Claims19
A method for making decorative concrete blocks, said method comprising the steps of:
- (i) providing at least one mold box comprising at least one chamber, the chamber having a horizontal plane which horizontal plane has a horizontal chamber surface area;
- wherein said mold box has a top surface, a bottom surface and at least one side surface;
- (ii) placing at least a portion of at least one liner in said chamber
- wherein said liner comprises a top surface, a bottom surface, at least one side surface, and a horizontal plane, which horizontal plane has a horizontal liner surface area,
- wherein the top surface of said liner is below the top surface of said mold box;
- (iii) providing a base plate comprising a top surface, a bottom surface and at least one side surface;
- (iv) contacting at least a portion of the bottom surface of said mold box with at least a portion of the top surface of said base plate;
- (v) placing a dry-cast concrete mix in said chamber to form an unmolded concrete block comprising a top surface, bottom surface, and at least one side surface;
- (vi) causing said mold box to vibrate;
- (vii) contacting pressurized gas with at least one of, at least a portion of the bottom surface of said liner, or at least a portion of at least one side surface of said liner;
- (viii) removing said molded concrete block from said mold box;
- and
- (ix) curing or allowing to cure said molded concrete block to form at least one cured concrete block.

A decorative concrete block making machine, said machine comprising a bottom assembly,
- wherein said bottom assembly comprises:
- (i) a vibration table comprising a top surface, a bottom surface, and at least one side surface;
- (ii) a base plate comprising a top surface, a bottom surface, and at least one side surface,
- wherein at least a portion of said base plate bottom surface is capable of contacting with at least a portion of the top surface of said vibration table,
- wherein said base plate comprises at least one bore extending from at least one of said base plate bottom surface or said base plate side surface to said base plate top surface, and
- wherein said base plate top surface comprises at least one base plate groove;
- (iii) at least one mold box comprising a top surface, a bottom surface and at least one side surface,
- wherein at least a portion of said bottom surface of said mold box is capable of being contacted with at least a portion of the top surface of said base plate,
- wherein said mold box comprises at least one chamber, the chamber having a horizontal plane, which horizontal plane has a horizontal chamber surface area,
- (iv) at least one device capable of contacting at least a portion of the bottom surface of said mold box with at least a portion of the top surface of said base plate,
- (v) at least one liner comprising a top surface, a bottom surface and at least one side surface,
- wherein at least a portion of the bottom surface of said liner is capable of contacting with at least a portion of the top surface of said base plate,
- (vi) at least one pressurized gas supplying equipment capable of providing pressurized gas which pressurized gas is capable of contacting with at least a portion of at least one of, at least one side surface, or the bottom surface, of said liner.
