Abstract
A continuous moulding device for producing building materials includes two pairs of drive sprockets (22) oppositely positioned at the inlet and the outlet of the device, a pair of chain conveyors (24) wound on the drive sprockets (22), with each chain conveyor having a connecting part (24a) on each of its links. A series of bottom plates (26) are connected to opposite connecting parts (24a) of the links. Side wall members (27) are pivotably connected to the sides of each bottom plate to form a transverse unit mould, and end pieces (30, 30'"'"') are connected to each bottom plate (26) to resiliently contact the ends of the unit mould. The unit mould can also be formed by separate side wall members (127) and bottom members (128), or by integrally formed bottom walls (210a) and side walls (210b, 210c) defined by a moulding conveyor belt (210). The device is used to form moulded products such as concrete beams, door frames or aluminum blocks with a high degree of dimensional tolerances. The bottom wall can be provided with a pattern for forming a pattern on the moulded product, such as a natural wood grain.
