Device for pressing a non-hardened concrete composition and method for the manufacture of concrete articles

A device (1) for pressing a non-hardened concrete composition (12) into a desired form, comprising:

• an upper plate (4) with one or more first cavities (7) that run through the upper plate (4);
• a moulding plate (3) with one or more second cavities (9), the upper plate (4) located directly above the moulding plate (3);
• a bottom plate (2) located under the moulding plate (3);
• and
• one or more stamps (5) located above the one or more second cavities (9),
• the upper plate (4) and the moulding plate (3) configured to move horizontally in relation to each other between a first position, in which the one or more first cavities (7) are directly and exactly above the one or more second cavities (9), and a second position, in which the one or more first cavities (7) are not above the one or more second cavities (9),
• a thickness of the upper plate (4) and not a thickness of the moulding plate (3) being decisive for a thickness of a final article produced by the device (1),
• the upper plate (4) and the moulding plate (3) configured to move vertically together between a lowest position, in which the bottom plate (2) closes the one or more second cavities (9) at a bottom of the moulding plate (3), and a highest position, in which the one or more second cavities (9) at the bottom of the moulding plate (3) is open such that non-hardened concrete articles (13) within the one or more second cavities (9) may exit from the one or more second cavities (9), and
• the one or more stamps (5) configured to move vertically through the upper plate (4) and the moulding plate (3) when the first cavities (7) are exactly above the second cavities (9) in the first position.
