Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0021] refer to figure 1 As shown, the method for the integral molding of the backlight source bottom shell and the plastic frame of the present invention by injection molding comprises the following steps:

[0022] The first step is to punch the bottom shell through a punching machine;

[0023] The second step is to open the safety door of the injection molding machine;

[0024] The third step is to align the light source of the bottom shell with the light source of the mold cavity, so that the bottom shell fits smoothly into the mold cavity;

[0025] The fourth step is to adjust the parameters of plastic frame molding on the injection molding machine;

[0026] The fifth step, inject rubber into the injection molding machine;

[0027] Step 6: Injection molding is started, the plastic frame is injection-molded, and the plastic frame and the botto...

Abstract

The invention discloses a method for integral injection molding of a bottom shell and a rubber frame of a backlight. The method comprises the following steps of: 1, performing punch forming on the bottom shell by using a punch; 2, putting the bottom shell subjected to punch forming in the step 1 into a cavity of a mould of an injection machine for injecting the rubber frame; and 3, injecting a sizing material into the cavity of the mould for injecting the rubber frame, beginning to inject the rubber frame, and making the rubber frame integrally molded with the bottom shell. The method has the advantages that: 1, the bottom shell and the rubber frame of the backlight are subjected to integral injection molding, so the anti-throw capacity and impact resistance of the rubber frame is improved under the support of the bottom shell; 2, the rubber frame and the bottom shell are subjected to integral injection molding, so the rubber frame can be made to be thinner under the support of the bottom shell, materials are saved, and a requirement that the backlight is manufactured to be thinner is met; and 3, the bottom shell and the rubber frame are subjected to integral injection molding, so manpower for assembling the rubber frame on the bottom shell is saved, and the production efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a processing technology of a backlight source, in particular to a method for integral injection molding of a bottom shell and a plastic frame of a backlight source. 【Background technique】 [0002] At present, the plastic frame and the bottom case of the backlight are separated from each other, and the plastic frame and the bottom case are assembled after they are manufactured separately. Since the plastic frame and the bottom case are assembled with each other, the plastic frame needs to have higher strength and resistance. The impact ability must be strong; at the same time, the thickness of the plastic frame is required. For a plastic frame that is too thin, its strength is difficult to support the light guide plate of the backlight. 【Content of invention】 [0003] The purpose of the present invention is to provide a method for making a structure that improves the strength of the plastic frame to overcome the disadvantage...
