Moulding equipment with cores for concrete casting machines

Moulding equipment (2) for concreting machines of the kind typically used for making cast items with cavities or corings in the shape of concrete blocks for erecting walls and elements, including a cellular bottom part (4) with cells (6) opening upwards as well as downwards which define the desired basic shape of the individual blocks and elements, and where the bottom part (4) includes at least one core member (8) placed in respective cells where the said cavities/corings in the mould are desired to be disposed, and a corresponding top part (14) which has pressing pistons (18) projecting downwards from an upper holding plate (16) and formed with lower pressing plates (20) that fit down into respective underlying cells (6) in the bottom part (4) and are thereby usable for downwards ejection of the cast items from the cells (6), and where the bottom part (4) includes means ensuring that the core members (8) keep their position in the bottom part (4), characterized in that the means ensuring that the core members (8) keep their position in the bottom part (4) are constituted by at least one top plate (10) supported by and releasably fastened to the bottom part (4), and that the core members (8) are fastened to the top plate (10), preferably by bolt connections such that between the core members (8) and the intermediate pieces (26) there is a vibration dampening shim (24).
