Mould for the mechanical production of concrete bodies

摘要

The invention proposes a mould for the production of concrete bodies in a moulding machine, which, for the purpose of compacting the concrete, is equipped with oscillators. The mould comprises a lower mould part and a punch. The lower mould part has at least one mould chamber which is bordered by walls and is open at the top and bottom. The punch comprises a punch head (1) and an applied-load member (3, 4). In order to facilitate the demoulding of the concrete body and to keep the mould clean, it is proposed that a vibrator (22) be arranged on at least one of the parts (1) of the mould, the frequency of which vibrator is considerably higher than the oscillating frequency, in particular above 11000 oscillations per minute. A compressed-air roller vibrator is preferably provided. For isolation from oscillation, there is provided, between the punch head (1) and the applied-load member (3, 4), a connection part (2) which contains rubber-metal vibration dampers (12) and/or a clearance-providing mount (15, 20, 21). <IMAGE>
