摘要

The mold with one or more molding chambers, especially for molding concrete bricks in a variety of cross section shapes, has at least two dies with vertical movement at the open upper side of each chamber. Each molding chamber (5) has at least one main chamber (6) and at least one ante-chamber (7) with an adjustable filling capacity, with a vertical dividing wall (8) between them. A die (12,13) is at each main chamber and each ante-chamber. There is a gap between the lower end (9) of the dividing wall and the bottom of the molding chamber.
