Description

Processing Mechanism of Transparent Light Guide

technical field

The utility model relates to a processing mechanism for a transparent light guide body.

Background technique

Existing injection molding product 1, as shown in accompanying drawing 1-Fig. The transparent light guide 1.2 in the middle, when injection molding, the tolerance fitting end 1.3 of one end of the injection molding product 1 is connected with the insert 2, and the tolerance fitting end 1.3 of one end of the injection molding product 1 has tolerance requirements and should correspond to the insert 2, In order to facilitate the processing of the tolerance of one end of the injection molded product 1 and the processing of the etched surface 1.1 of the end of the end 1.3 and the processing of the tolerance size, the processing can be completed by slow wire-feeding processing. Since the tolerance of insert 2 and the tolerance matching end 1.3 of one end of injection molded product 1 are the same, the tolerance range of injection molded product can be cut out by slow-moving wire, and the surface of insert 2 can be etched directly, thus solving the problem of glue depth The problem of difficult etching. However, the etched edges on the butt etched surface 2.1 of the insert 2 are prone to rounded corners, which in turn causes the etched surface of the injection molded product 1 to be easily out of alignment.
