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.

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.

The rotary apparatus includes a carriage body including a carriage upper portion supported by first and second carriage rails, and a carriage lower portion extending downward from the carriage upper portion laterally intermediate the first and second carriage rails. The rotary apparatus further includes a rotary table mounted atop the carriage body for rotatably supporting the center mold section. The rotary table is mounted to the carriage body by a rotary table bearing having a combination of bearing elements to bear axial, rotational, and moment loads. The machine further includes a plurality of tie bars extending between the moving platen and the stationary platen. The tie bars are free from engagement by the rotary apparatus.

Injection molding machine with rotary apparatus

An injection molding machine includes a first mold section comprising mold cores for forming threaded articles, the first mold cores movable between a molding position for interacting with a second mold section in a mold area to form the threaded articles, and an auxiliary position outside the mold area, and a removal device for removing the threaded articles from the mold cores. The removal device includes a plurality of unscrewing chucks for engaging the threaded articles when the mold cores are in the auxiliary position. The chucks are supported by a carrier plate and each chuck is rotatable about a respective unscrewing axis. The removal device further includes an orbiting plate coupled to the unscrewing chucks by respective crank arms, the orbiting plate effecting synchronized rotation of the unscrewing chucks via the crank arms for unscrewing the threaded articles from the mold cores.
