Abstract: Pivotable side cores (4) for a lower mould part (2) in a concrete casting machine of the kind typically used for making cast items (11) in the form of concrete blocks for pavements, wall construction or elements, solid blocks and blocks with cavities or recesses.
By the pivotable side cores (4), recesses (12) can be made at the side of products, where these recesses (12) at the side of the product do not extend through to the top side of the product.
By the invention are indicated pivotable side cores (4) in a lower mould part (2) including means (3,7,8) that ensure that the core members forming the cavities retain their position in the lower part during compression, and at the same time are pivoted off the product during the demoulding.
