Abstract:
Moulding equipment (2) for concrete moulding machines of the kind which is typically used for the production of mould items in the form of tiles and bricks for paving and wall constructions, and comprising a cell-divided under-part (16) with cells (18) which are open both upwards- and downwards, and which define the desired basic shape of the individual paving tiles or bricks, and a corresponding under-part (2) which from an upper retraining plate (4) has downwards-extending pressure plungers (6) which are formed with lower pressure plates (8) which pass down into respective, underlying cells (18) in the under-part (16), and are hereby usable for downwards ejection of the mould items from the cells (18), wherein the upper-part (2), alternatively the under-part (16), comprises means (20, 24) which ensures that the pressure plates (8) maintain their position opposite the sides, or their guiding engagement with the sides (14) of the therewith corresponding cells (18) in the under-part (16) when the under-part (16) is raised to a certain minimum height which is greater than the thickness of the mould items, during stripping of the mould items from the cell-divided under-part; wherein the means which ensure that the pressure plates (8) maintain their position outside, or their guiding engagement with the sides (14) of the therewith corresponding cells (18) in the under-part (16), consist of the upper-part (2) comprising at least one guiding pressure plate (8â€²) which is configured with upwards extension (20) so that it maintains guiding engagement with the sides (14) of the therewith corresponding cell (18) in the under-part (16) when this is raised to a certain minimum height which is greater than the thickness of the thinnest or lowest under-parts.
