Abstract
An arrangement for receiving a multi-part casting mold, in particular an at least two-part blow mold. A drive unit for displacing locking elements has a main cylinder with a main piston and a travel cylinder with a travel piston, wherein the travel cylinder is connected with the main piston of the main cylinder and is movable therewith. The travel piston has a piston rod, which is connected with the locking element and is mounted concentrically displaceably in the main piston. In the operating condition of the molding process, the travel piston abuts on the main piston, wherein the main cylinder provides the locking force to keep the mold closed during the molding process.
