Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate production, in particular to a mold temperature control machine for manufacturing injection-molded light guide plates. Background Art

[0002] The light guide plate is a transparent plate, usually made of optical-grade plexiglass or polycarbonate and other materials. Its main function is to convert point light source or line light source into a uniform surface light source. When the light guide plate is injected, a temperature controller is needed to heat the light guide plate mold. However, in actual use, the existing temperature controller will cause the heating barrel to be heated for a long time, and the ditch will adhere to the inner wall of the heating barrel. At the same time, it is difficult to make it fall off automatically without external force, which will make the scale cleaning work inside the heating barrel incomplete. At the same time, more scale accumulates at the discharge port, and the scale clumps, blocking the discharge port, making it difficult to discharge the scale in a short time. The staff also needs to use tools to clear the discharge pipe, which has certain limitations when used.

[0003] In order to solve the above problems, the publication number CN220031097U discloses a "mold temperature controller" that uses a servo motor, a threaded rod, a driving gear, a driven gear and a scraper to facilitate the better discharge of scale and avoid blockage. However, the device still has certain defects in actual use. For example, the device drives the scraper to rise and fall through the threaded rod to clean the scale on the inner wall of the heating barrel. When the scraper cleans the scale on the inner wall of the heating barrel, the scraper will rub against the inner wall of the heating barrel, causing the scraper to be severely worn after a period of use and unable to effectively clean the scale on the inner wall of the heating barrel. In addition, the device can only heat the light guide plate mold, but cannot cool the light guide plate mold. Utility Model Content
