ABSTRACT:
The mold for the production of concrete shaped bricks has several mold cavities, which are filled with free-flowing concrete. To produce recesses in the interior or on the outer sides of the shaped brick, to each mold cavity there correspond one or more mold cores which penetrate a wiping plate that lies below the mold and project from the bottom into the mold cavities. To demold the shaped brick, the mold cores that are arranged on a core support plate are run out from the mold cavities by a vertical movement relative to the mold and to the wiping plate to the upper limit of the wiping plate, and then the unit that consists of the wiping plate and core support plate is run out in the horizontal direction from the area of the mold.
