Mold having movable plate-shaped core

Abstract

A mold for fabricating an optical fiber connector is disclosed. The optical fiber connector includes a blind hole for accommodating an optical fiber and an aspherical lens portion for being optically coaxial with the optical fiber. The mold includes a rod-shaped core for forming the blind hole and a plate-shaped core. The plate-shaped core includes an aspherical recess for forming the lens portion. The aspherical recess faces the rod-shaped core and is adjustably movable relative to the rod-shaped core to achieve alignment between the aspherical recess and the rod-shaped core.

What is claimed is: 
     
         1 . A mold for fabricating an optical fiber connector, the optical fiber connector comprising a blind hole for accommodating an optical fiber and an aspherical lens portion for optically coupling with the optical fiber, the mold comprising:
 a rod-shaped core for forming the blind hole; and   a plate-shaped core comprising an aspherical recess for forming the lens portion, the aspherical recess facing the rod-shaped core, the plate-shaped core being adjustably movable relative to the rod-shaped core so as to achieve alignment between the aspherical recess and the rod-shaped core.   
     
     
         2 . The mold of  claim 1 , comprising a male mold, the rod-shaped core extending through the male mold. 
     
     
         3 . The mold of  claim 1 , comprising a female mold, the plate-shaped core extending through the female mold and being movable relative to the female mold. 
     
     
         4 . The mold of  claim 1 , comprising a spacer disposed between the plate-shaped core and the female mold. 
     
     
         5 . A mold for fabricating an optical fiber connector, comprising:
 a male mold;   a female mold attached to the male mold, the male mold and the female mold cooperatively defining a molding cavity, the female mold having a through hole in communication with the molding cavity;   a plate-shaped core extending through the through hole, the plate-shaped core having a distal end exposed in the molding cavity and a plurality of aspherical recesses defined in the distal end; and   a plurality of spacers selectively disposed between the plate-shaped core and the female mold in the through hole, the spacers configured for adjusting the plate-shaped core.   
     
     
         6 . The mold of  claim 5 , wherein another distal end of the plate-shaped core is opposite to the distal end exposed in the molding cavity and is positioned outside the female mold.
