Improvements in the machines for molding concrete pieces of the kind in which the mold holder frame is tiltable and the compressor-ejector moves in the demolding operation, which are characterized in that the mold is made with the two open bases plugged in by one of them in the extractor-compressor device, and the opposite one that is inclined, has an inclined board in relation to the horizontal plane, for which the lower dies are designed and dimensioned in such a way that the board that closes the mold by said upper base does not contact said dice and is regularly spaced from them, in order that the manufactured piece has its corresponding lateral face covered and not parallel with the face that remains open.
