[ What is claimed is:] [1.]1. Adjustable mold apparatus for injection molding of a fiber optic ferrule, said mold apparatus comprising, in combination, a mold having a bore therein to define a cylindrical mold cavity for molding a body portion of a ferrule, core pin means having a segment thereof designed to define an interior longitudinal passage in said body portion of said ferrule, said core pin means having wire means projecting from a forward end thereof to define a small diameter longitudinal hole in said ferrule communicating with the outer end of said interior longitudinal passage, first adjustable means for locating said wire means, said first adjustable means being positioned in a first half of said mold and including first rotatable means having a small eccentric hole dimensioned to receive and position said wire means when said mold is closed, second adjustable means for locating said core pin means, said second adjustable means being positioned in a second half of said mold and including second rotatable means having an eccentric hole for receiving and supporting a rear portion of said core pin means while a forward portion of said core pin means including said wire means projects into said bore in said mold when said mold is closed, whereby said first adjustable means may be used to locate said projecting wire means substantially concentric with the true center of said bore in said mold and said second adjustable means may be used to locate said core pin means substantially concentric with said true center of said bore in said mold.
