Injection mold for improving internal forming stress of vehicle-mounted light guide plate

The utility model relates to an injection mold for improving the internal forming stress of a vehicle-mounted light guide plate, which comprises a front mold and a rear mold, the front mold comprisesa front mold core, the rear mold comprises a rear mold core, a mold cavity for forming the light guide plate is arranged between the front mold core and the rear mold core, and the front mold core isprovided with a lattice point forming surface for forming lattice point surfaces of the light guide plate. And when the injection mold is completely closed, the thickness of the mold cavity is a, andthe thickness ratio a of the mold cavity of the injection mold in the primary stage of injection molding filling is 0.02-0.03 mm, so that a 0.02-0.03 mm gap for exhausting the parting surface of the mold cavity is formed. When the primary stage of glue injection molding filling starts to inject glue, a 0.02-0.03 mm mold closing gap is controlled between the front mold and the rear mold and the glue injection time is maintai
