摘要:
Disclosed are a molded article picker for a post-mold device and a related method for the use of the molded article picker for handling a molded article. The molded article picker includes a floating element being configured to be movable between an extended position and a retracted position and biased in the extended position. Furthermore, the molded article picker comprises a pressure structure extending through the floating element. The floating element is cooperable with the molded article to define a substantially enclosed volume including the pressure structure. The pressure structure is configured such that by evacuating the substantially enclosed volume the molded article is sealed to the floating element and the floating element is drawn into the retracted position, thereby transferring the molded article to the molded article picker.
