Abstract

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.
