A lifter system and apparatus having a rotational gib for molding plastic parts, in large mold machines or small mold machines. A core blade is movably mounted with respect to a mold. A gib, such as a rotational gib, is mounted with respect to an ejector plate of the mold. A rotational mount is fixed with respect to the gib. The core blade can be moved and releasably locked at or into different positions with respect to the gib. The rotational mount can be releasably locked with respect to the gib. A detent, a bias element and a spherical surface or other contact surface can be used to hold or fix a position of the core blade with respect to the gib. A second detent, a second bias element and a second spherical surface or other contact surface can be used to hold or fix a position of the rotational mount with respect to the gib.

Lifter system with rotational GIB

A module or unit manufactured allowing simplified installation of a lifter rod assembly of a core lifter apparatus for a mold for molding plastic parts. In some embodiments, a slide is movably mounted with respect to a retainer and/or a gib, so that the retainer attached to the lifter rod can be moved in a linear direction and a rotational direction to provide free motion and reduce wear and breakage due to uneven ejector plate movement during production cycling of the mold. In some embodiments, the slide has one or more spring-loaded devices that hold the retainer in a particular position with respect to the slide, positioned to receive the lifter rod during mold assembly. In some embodiments, the retainer accommodates connections and coiled hoses for delivering cooling fluid to an internally cooled lifter rod.
