Patent ID: 8287797

Claim:
A device for molding plastic preforms into plastic containers, comprising: at least one blow mold; a plurality of closure members interacting with each other to transfer the blow mold between an open state and a closed state, wherein the blow mold includes a cavity within which the plastic preforms may be molded into the plastic containers, wherein the closure members comprise: at least one first mold part; at least one second mold part, wherein the at least one first mold part and the at least one second mold part are moveable with respect to one another between the closed state and the open state; and a blow nozzle unit which is moveable with respect to the at least one first mold part and the at least one second mold part and which is positioned over the cavity in the closed state of the blow mold; at least one first drive unit that moves the at least one first mold part and the at least one second mold part with respect to one another; a second drive unit that moves the blow nozzle unit with respect to the at least one first mold part and the at least one second mold part, wherein at least one of the first and second drive units moves at least one of the closure members to transfer the blow mold between the closed state and the open state; and at least one treatment unit that treats the preforms during the molding operation, wherein at least one drive unit for moving at least one of the closure members for transferring the blow mould between the closed state and the open state or at least one drive unit for operating the treatment unit is an electric drive unit, wherein the device comprises an electrically operated pressure mechanism that applies a mechanical load to the blow mold, and wherein the pressure mechanism comprises a lever element.
