FIELD: equipment for manufacture of building articles from concrete mixes, in particular, multicavity molds for production of facing tiles from sand-concrete mixes by casting methods. SUBSTANCE: upon finishing of mold assembly, space between fixed separating partitions 7 and movable separating partitions 10 are filled with cement-sand mix which is help up to attainment of strength required for mold removal. Then mold is sent to station for mold dismantling. For mold dismantling, mechanical coupling 5 is loosened to ensure turning of movable end side 4 through an angle of alpha. Further on, screw pairs 3 are rotated by screws to press out movable end sides 4 from fixed longitudinal sides 2 through an angle of alpha to ensure coming of end of retainer 8 out of zone of its contact with movable separating partition 10 and lifting it to height equalling difference R1-R. Then, movable separating partitions 10 together with articles are removed from mold, articles are separated, and mold is directed for cleaning and lubricating station. EFFECT: provision of production of facing tiles with no cracks and stores of sand-concrete mixes by using casting techniques. 5 dwgo
