Abstract
The operating i.e. the sand blowing unit (1) of a moulding machine is connected non-positively to the moulding i.e. the core box or mould box unit (3) during the operating cycle and guided freely in a form-fitting manner by the machine frame. The non-positive connection is made by means of parts corresponding to one another, preferably from clamping devices (2) and journals (4). The clamping devices are movable horizontally and vertically by drive means.
