To cast a bowl-shaped concrete body, a hollow mold is on a lifting table (3) with an integrated vibration mechanism (5), to be moved up and down. The mold has an inner mold core (20) with a perforated base, an outer mold mantle (21) and a mold ring (22) at one end side. The inner mold core is bonded to a carrier frame (26), which has no free play on the support surface through clamps and holder during the concrete filling and compression stages. An inverting mechanism (10) can rotate the hollow mold and concrete filling structure by 180 deg after covering. All the couplings and fittings to lock and hold the hollow mold are integrated into the machine components.
