A spouting cast for wedge-shaped light guide plate is provided to prevent fault due to distortion of the light guide plate by designing the distance from the FL(Fitting Line) to the fixed unit cooling channel and the distance from the FL to the moving unit cooling channel asymmetric. A spouting cast for wedge-shaped light guide plate comprises a fixed unit(110) arranged in a side about an FL, a moving unit(120) which is arranged in the other side and defines a spouting space(105), a gate(115) injecting the molten resin of high temperature into the spouting space, a fixed unit cooling channel(150a) which is arranged in the fixed unit and let cooling water flow through, and a moving unit cooling channel(150b) which is arranged in the moving unit and let cooling water flow through.
