Device for blow-molding containers
View Patent ↗The device serves for the blow molding of containers that comprise a thermoplastic material, wherein the device has at least one blowing station with at least one blow mold. The blow mold is formed from at least two blow mold segments that are supported by supports, wherein the blow mold has a base extension. The base extension is arranged in such a way that it is capable of being positioned in the direction of a longitudinal axis of the blow mold, and is supported by a base plate. The base plate connects the base extension to a positioning device. The base plate is additionally connected to the base extension by a profiled coupling section, wherein this profiled coupling section is formed from a coupling element, which is connected to the base plate, along with a counter element that is connected to the base extension. The profiled coupling section is capable of being actuated via a manual lever. At least two hollow coupling plugs are arranged a certain distance from the profiled coupling section, wherein these coupling plugs are capable of being introduced into self-sealing coupling sockets.
