A carrier assembly for injection molding a parison with internal threads. The carrier assembly may be used with an injection stretch blow molding machine that includes a core rod. The carrier assembly comprises a carrier insert surrounding a portion of the core rod. The carrier insert includes a thread-forming portion presenting an interior radial surface and an exterior radial surface. The interior radial surface is configured to be positioned adjacent to the core rod, and the exterior radial surface includes a threaded protrusion configured to extend away from the core rod. The carrier assembly also includes a pinion insert surrounding at least a portion of the threaded protrusion of the thread-forming portion of the carrier insert. The pinion insert is spaced apart from the thread-forming portion of the carrier insert so as to present a thread-forming cavity between the pinion insert and the carrier insert.

A threaded mold decoupling system includes at least one unscrewing assembly configured to remove a molded article a threaded core of an injection mold, an elevator assembly, and a driving element disposed in operative communication with the at least one unscrewing assembly and with the elevator assembly. The driving element is configured to actuate the at least one unscrewing assembly to rotate a molded article about a longitudinal axis of the threaded core and actuate the elevator assembly to linearly translate the molded article along the longitudinal axis of the threaded core.

A threaded mold decoupling system includes at least one unscrewing assembly rotatably coupled to a mounting plate and disposed in proximity to a threaded core of an injection mold, an elevator assembly having a first elevator element rotatably coupled to the mounting plate and a second elevator element connected to a fixed plate, the fixed plate opposing the mounting plate, and a driving assembly disposed in operative communication with the at least one unscrewing assembly and with the first elevator element of the elevator assembly. The driving assembly is configured to actuate the at least one unscrewing assembly to rotate a molded article about a longitudinal axis of the threaded core and actuate the first elevator element relative to the second elevator element to linearly translate the mounting plate relative to the fixed plate and to translate the molded article along the longitudinal axis of the threaded core.
