A mould device for manufacturing in particular concrete pipes is proposed, which has a mould casing, a mould core which is placed exchangeably on a central vibrator, as well as an upper muff and a lower muff. Between the central vibrator on the one hand and the inner mould core on the other hand, there is provided a rotary bearing in the form of at least one roller bearing which allows relative rotary mobility between both parts in both circumferential directions. The rotary bearing can be locked or freed by a coupling device with locking element. The inner mould core is also alternatively drivable via a connectable, steplessly adjustable drive, the direction of rotation of which is reversible. The mould device makes possible improved compaction of the concrete in the case of unreinforced and in particular reinforced concrete parts, in particular also those with external contours which are not rotationally symmetrical. Moreover, better adaptation to the shape of the concrete part and also the concrete mix is possible.
