An assembly mold for light guide plate production

Abstract

The invention discloses a splicing mold for light guide plate production. The splicing mold comprises multiple splicing mold units connected through connecting inserts; the splicing mold units include mold frames spliced by transverse inserts and longitudinal inserts, and mold cores positioned in the mold frames; the splicing mold comprises two splicing mold units: respectively a front mold and a back mold; and the front mold and the back mold are connected through a connecting insert, and both include rectangular mold frames spliced by transverse inserts and longitudinal inserts. The bonding places of the transverse inserts and the longitudinal inserts with the mold cores are step structures. The transverse inserts and the longitudinal inserts are both provided with thread fastening pieces for locking the molds. The splicing mold uses a detachable splicing mold structure, can reasonably set the mold layout according to product demands, can prominently improve the product quality and the production efficiency, is convenient for disassembly, easy to machine and smooth in demolding, can timely exhaust waste gas in a molding cavity, facilitates realization of quick product molding, and greatly improves the product performance.

Description

technical field [0001] The invention relates to the production technology of the light guide plate, in particular to an assembled mold used for the production of the light guide plate. Background technique [0002] With the popularity of smart phones in the past two years, the scale of the TFT-LCD industry in the mobile phone industry has continued to expand, and there is a trend of high-end development. In the development process of the mobile phone manufacturing industry, the forming process of some parts and components needs to be completed by molds. Because mold processing and forming parts have complex structure, surface, high precision requirements, good resin fluidity, short manufacturing cycle and other requirements. As the core component of the backlight, the requirements for the light guide plate mold are getting higher and higher, and the traditional mold design method can no longer meet the current requirements. [0003] Most of the traditional light guide plat...

Problems solved by technology

As the core component of the backlight, the requirements for the light guide plate mold are getting higher and higher, and the traditional mold design method can no longer meet today's requirements

[0003] Most of the traditional light guide plate production molds still stay in the establishment concept of the integral mechanical structure, which has the following disadvantages: 1) The mold is not easy to process, and the precision cannot be achieved, which directly affects the product size, brightness after lighting, effect after lighting, and uniformity after lighting etc.; 3) The mold is not well exhausted during the forming process, and the resin fluidity in the mold is poor, resulting in difficulty in thickness forming; 2) The formed LGP effect is prone to burrs and air marks, resulting in a display effect that does not meet the requirements; in the traditional In the mold design concept, if the above problems are improved, a more complex mold structure needs to be designed, such as the light guide plate mold disclosed in Chinese patent ZL201410123671.7 and the light guide plate mold disclosed in Chinese patent ZL201310146831. Improvement requires the addition of multiple complex structures, which has become an inertial thinking dilemma that is difficult to break through in the design of light guide plate molds
