Rubber-iron integrated vehicle-mounted backlight source and processing device thereof

Abstract

The invention discloses a rubber-iron integrated vehicle-mounted backlight source and a machining device thereof, and relates to the technical field of rubber-iron integrated vehicle-processing backlight source machining, the rubber-iron integrated vehicle-mounted backlight source comprises a main body, a fixing block is fixedly arranged on the inner wall of the main body, a fixing shaft is fixedly arranged at one end of the fixing block, and a cam column is fixedly arranged on the outer side of the fixing shaft. Positioning and fixing pieces play a role in positioning and limiting when a back plate is placed in a containing cavity, in the plastic frame injection molding process, a molten plastic frame solution can wrap the multiple sets of positioning and fixing pieces, connection between the plastic frames and the back plate is more stable, the risk of falling is avoided, and after one set of plastic frames are subjected to injection molding and solidification, multiple sets of lower mold frames rotate by a certain angle, at the moment, the cam column pushes the ejector rod to push the back plate and the rubber frame out of the containing cavity and the injection molding cavity together, the ejection and demolding effects on the back plate and the rubber frame subjected to injection molding can be achieved, the new set of lower mold frames can also be rotated to the injection molding position, and the overall injection molding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of rubber-iron integrated vehicle-mounted backlight processing technology, in particular to a rubber-iron integrated vehicle-mounted backlight source and a processing device thereof. Background technique [0002] With the development and popularization of smart cars, liquid crystal displays have become an indispensable part of the car. The LCD display in the car can greatly facilitate the interaction between the driver and the driving computer, check the status of the car, and reduce the pressure on the driver. In order to better dissipate heat and reduce the thickness of the backlight for the vehicle-mounted backlight, the base of the backlight is usually made of metal materials such as aluminum, aluminum castings, aluminum alloys, or iron. [0003] Vehicle backlight is a kind of light source located behind the liquid crystal display screen. Its luminous effect will directly affect the visual effect of the ...

AI Technical Summary

Problems solved by technology

[0005] Based on this, the purpose of the present invention is to provide a rubber-iron integrated vehicle-mounted backlight and its processing device to solve the problem that the plastic frame will be detached from the backplane to a certain extent in the prior art for a long time and that a separate power is required in the existing injection molding demoulding process. The technical problem of low work efficiency due to the ejection and reset of the ejector rod by the equipment
