DSF MOLD DEVICE FOR MANUFACTURING LIGHTGUIDE IN A BACKLIGHT SYSTEM

摘要

A primary object of this invention is to provide a new structure of DSF mold for backlight system made by assembling multiple blade molds to function as a master stamp, which will decrease the manufacturing cost because the mold will be modified easily when a failure occurs in manufacturing process, due to its assembling characteristics. In carrying out the invention, there is provided; A mold system for manufacturing light guide plate comprising : at least one base mold supporting multiple blade molds; a set of multiple blade molds disposed in parallel and supported by said base mold, wherein edge shape of each blade mold is sharp for forming grooves on a surface of light guide plate; at least one assembly hole formed on sides of each blade mold; at least one assembling means that penetrate said assembly hole in series of all blade molds; and fixture means for compressing both sides of said set of blade molds to secure portions of said blade molds, positioned at each end of said assembling means.
