Apparatus and method for forming of the plastic parisons to plastic containers with air which is guided by a water lock

摘要

A device for shaping of plastic parisons (10) to plastic containers (10a) with at least one blow station (8), which on a by a predetermined axis of rotation (d) rotatable transport device (2) is arranged, wherein the blow station (8) a blow mold, and this blow mold has a cavity is formed in the interior of the plastic preforms (10) by means of action with a gaseous medium to form the plastic containers (10a) are expandable, with an actuating device, which the plastic preforms (10) to their expansion with the gaseous medium is admitted and with a clean room (20), which the blow station (8) at least partially surrounds, wherein this clean room (20) by means of at least two walls (18, 19, 162, 164), which are movable relative to each other, is delimited with respect to an environment, and the device has a sealing device (140), which the clean room in a range of the relatively moving walls (18, 19, 162, 164) with respect to the environment, wherein said seal means (25) a first circumferential which can be filled with a liquid medium channel (142), as well as a with respect to this channel (142) movable first circumferential wall body (146), the at least sectionwise within the liquid medium can be guided. According to the invention extends in at least one section of the channel (142) a line (80) for a flowable medium, wherein said flowable medium by means of this section of the channel (142) can be guided and permanently of the liquid medium located in the channel is separated.
