Abstract: An injection molding machine includes a base; a pair of platens supported by the base, the platens supporting respective mold halves to form a mold; and a part-handling apparatus for holding and treating articles from the mold, the part handling apparatus separate from the mold. The part handling apparatus includes a take-out plate including at least one set of first cooling receivers for receiving and retaining a first set of molded articles from the mold, the first cooling receivers conductively transferring a first amount of thermal energy away from the first molded articles; and a supplemental cooling plate comprising at least one set of second cooling receivers for receiving and retaining the first set of articles; and the second cooling receivers conductively transferring a second amount of thermal energy away from the first molded articles.

Abstract: A method for cooling molded preforms includes transferring preforms of a first injection cycle from a mold to retained engagement on a take-out plate, the preforms having exterior surfaces and interior surfaces targeted for cooling. The preforms are released from cooling tubes of the take-out plate to retained engagement on cooling pins of a transfer shell spaced away from the mold. The transfer shell rotates and the preforms are released from the transfer shell to retained engagement in supplemental tubes of a supplemental cooling device. After a period of time the preforms are released from the supplemental cooling device and transferred back to retained engagement on the transfer shell. The transfer shell rotates to an unload position to eject the preforms from the transfer shell for evacuation from the machine.
