Backlight glue frame iron case integrated forming technique

Abstract

The invention provides a backlight glue frame iron case integrated forming technique which has characteristics that: an iron case (1) is placed in an injection glue frame die (2) for injecting, the iron case (1) is made to order with a special structure and block groove, utilizing clearance space of normal iron case (1) and glue frame (2) for manufacturing separately and assembling in injection, the iron case (1) is filled with plastic glue, the plastic glue fills the block groove of the iron case (1) for forming the glue frame, the iron case (1) and the glue frame (2) combine tightly, the iron case (1) locates on outside, the glue frame (2) locates on inside for forming the integrated structure which has high intension, little space and can reach design aim.

Description

technical field [0001] The invention relates to an integrated molding process of a plastic frame and an iron shell of a backlight source. Background technique [0002] With the development of science and technology, mobile phones are developing in the direction of multi-function and ultra-thin. While the functions are powerful, there are more and more internal parts of the corresponding mobile phones, and the development of ultra-thin, the internal space becomes smaller and smaller, forming Therefore, the space of each component is compressed, and the corresponding backlight is used as an internal part of the mobile phone, and its usable space is getting smaller and smaller, which leads to the development of the backlight to ultra-thin thickness and ultra-thin frame. There are backlights, and some directly use plastic frames to fix the components of the backlight. Due to the ultra-thin requirements, the plastic frame becomes thinner in terms of structural size. When molding,...

[0002] With the development of science and technology, mobile phones are developing in the direction of multi-function and ultra-thin. While the functions are powerful, there are more and more internal parts of the corresponding mobile phones, and the development of ultra-thin, the internal space becomes smaller and smaller, forming Therefore, the space of each component is compressed, and the corresponding backlight is used as an internal part of the mobile phone, and its usable space is getting smaller and smaller, which leads to the development of the backlight to ultra-thin thickness and ultra-thin frame. There are backlights, and some directly use plastic frames to fix the components of the backlight. Due to the ultra-thin requirements, the plastic frame becomes thinner in terms of structural size. When molding, the yield is not high, so the cost is high. After the plastic frame is formed, The mechanical strength is low and easy to be damaged. Some of them reinforce the iron shell on the outside of the plastic frame to improve the mechanical strength and have a certain shielding effect. However, the plastic frame and the iron shell are formed separately. When they are reassembled, there is a certain space between them. It takes up more internal space of the mobile phone and does not meet the ultra-thin requirements. Moreover, when the two accessories are combined, the structural size is small, the glue position of the plastic frame structure is too small, the structural dimensional accuracy is high, the molding is difficult, and the cost is high.
