Abstract: A system for the automatic release of cast concrete products from flexible and deformable moulds is described. The system has an apparatus configured to supply the moulds and carry out the pre-mould-release of the products contained within such moulds. The apparatus has a first conveyor belt associated with a first pre-mould-release group and a second conveyor belt associated with a second pre-mould-release group. The second conveyor belt is placed downstream of the first conveyor belt and both pre-mould-release groups are configured to facilitate the subsequent mould-release of the products. The system further has a mould-release machine arranged downstream with respect to the first and second conveyor belts. The mould-release machine has a mould-release group, configured to carry out the extraction of the products from the respective moulds, and a plurality of conveyor belts, configured to move the moulds and the products inside the mould-release machine.

Abstract: A mold for building coating products obtained from composite liquid mixtures is described. The mold includes a base plate, having a plurality of through holes; and a die, configured for incorporating the base plate therein. On the upper surface of the die there are a plurality of shapes of the front surface in negative of each coating product to be manufactured and a molding grid open at the upper part, configured to be pressure applied above the die. The molding grid has side walls which define the perimeter edges of each coating product. Between the molding grid side walls separate bowls are formed for containing a single coating product. Each side wall is inclined at an acute angle with respect to a vertical plane, to confer to each side wall a sharp-pointed and tapered shape from top towards bottom with respect to the entire mold for facilitating the extraction of the finished coating products.
