Abstract:
1. 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 ).
