Abstract
The present invention is related to a rotary cooling station to be used in conjunction with a high output injection molding machine and a robot having a take-out plate. More particularly, the present invention teaches a high speed robot that transfers warm preforms onto a separate rotary cooling station where they are retained and internally cooled by specialized cores. The preforms may also be simultaneously cooled from the outside to speed up the cooling rate and thus avoid the formation of crystallinity zones. Solutions for the retention and ejection of the cooled preforms are described. The rotary cooling station of the present invention may be used to cool molded articles made of a single material or multiple materials.
