Abstract
A closing unit for a shaping machine includes mutually moveable mold mounting plates suitable for carrying mold tool portions, a first hydraulic cylinder adapted to apply a closing force to the mold mounting plates, a second hydraulic cylinder, and a pressure storage device connected to the first hydraulic cylinder and adapted to store a pressure prevailing in the first hydraulic cylinder upon pressure relief at a storage device pressure. A hydraulic interconnection of the pressure storage device with the second hydraulic cylinder allows the storage pressure stored in the pressure storage device to be used for locking and/or unlocking the locking device.
