Abstract

The present invention is a design of side gate of a diffuser injection mold for a backlight module. Mainly, a plurality of fan-shaped feeders are installed on the side surfaces of the cavity corresponding to the injection mold of a formed diffuser (that is, the mold surfaces corresponding to the sides of a formed diffuser) so that the liquid diffuser material is controlled by the fan-shaped feeders during filling. With a plurality of fan faces operating in a way to perform serial filling to mutually cancel fast and slow filling flow states, the liquid diffuser material can flow and evenly fill the cavity at a constant speed to allow the diffuser to harden under a minimum internal stress. Therefore, large-size diffusers of uniform luminance without any warping can be produced.
