MOLD FOR INJECTION COMPRESSION MOLDING OF LIGHT GUIDE PLATE AND METHOD FOR INJECTION COMPRESSION MOLDING OF LIGHT GUIDE PLATE

摘要

The invention provides an injection compression forming die for a light guide plate which can respectively remarkably transfer the light guide plates formed diversely, and an injection compression forming method for a light guide plate. In the injection compression forming die for the light guide plate (11) which is formed, in a manner of deformation, at a distance of a cavity main face forming face (18a) of a movable die (12) opposite to the cavity main face forming face (42a) of an immovable die (13), a cavity main face forming module (18) of the cavity main face forming face (18a) is formed, and cavity side face forming modules (29, 30, 31), which are provided at least in opening and closing directions of the dies opposite to the cavity main face forming module (18) in a manner of being capable of changing the opposite directions, can be provided replaceably.
