Abstract: A method for receiving and ejecting molded articles includes: (a) drawing air from a cooling tube cavity into an air channel through a plate bore to draw at least a portion of a molded article into the cavity; (b) moving a valve within the plate bore from a first position for conducting air from the cavity to the air channel to a second position for reducing air flow through the plate bore relative to the first position; and (c) when the valve is in the second position, urging pressurized air from the air channel to the cavity through the plate bore to assist ejection of the molded article from the cavity.

Abstract: A method for injection molding comprises forming a set of first articles in a mold of an injection molding machine and forming a set of second articles in the mold of the injection molding machine. The method includes transferring the set of first articles from the mold to a first set of first receivers of a tooling plate, and then moving the first set of first receivers to align with the set of second articles. Thereafter the set of second articles is transferred from the mold toward the first set of first receivers and into assembled condition with the set of first articles held in the first set of first receivers.

Abstract: A cooling plate assembly includes (a) a cooling plate having a plate front surface; (b) an air channel extending within a thickness of the cooling plate; (c) a plate bore extending into the cooling plate from the plate front surface for providing fluid communication between the air channel and a cavity of a cooling tube mountable to the cooling plate; and (d) a valve within the plate bore. The valve is movable between a first position in which a first air flow passage extending within the plate bore is open for conducting air from the cavity to the air channel, and a second position in which the first air flow passage is obstructed to reduce air flow between the cavity and the air channel, and in which a second air flow passage extending within the plate bore is open for conducting air from the air channel to the cavity.

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.
