Abstract

The invention relates to the technical field of dies, in particular to a compression die for an oil cylinder of a light guide plate. The key points of the technical scheme are that the compression die comprises a die base and the oil cylinder, the oil cylinder is arranged in the die base, the die base comprises an upper die assembly and a lower die assembly, the upper die assembly comprises an upper die base and an upper die core, the upper die core is installed at the bottom of the upper die base, the lower die assembly comprises a base, a lower die cushion block, a lower die base and a lower die core, the lower die cushion block is arranged on the top of the base, the lower die base is arranged on the top of the lower die cushion block, the lower die core is installed on the top of the lower die base, the upper die core and the lower die core are right opposite to each other and form a cavity, and the oil cylinder is arranged in the lower die assembly and controls compression of the cavity. According to the compression mold for the oil cylinder of the light guide plate, the risk of cylinder explosion can be reduced in the injection molding process of the light guide plate.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a light guide plate oil cylinder compression mold. Background technique [0002] The term light guide plate comes from the translation of English Light Guide Plate, which is produced to match the liquid crystal display panel. The liquid crystal display requires a backlight module to display its brightness due to its non-self-luminous characteristics. At present, with the expansion of the application range, the light guide plate is used in various display fields such as display screens and instrument panels. Since the light emitting system is generally a point light source, such as LED lights, and the entire display system, especially the background light, requires uniform brightness. This requires the light guide plate to use the light diffusion to make the light uniform, that is, to convert the point light source into a uniform surface light source, and to minimize the number of...
