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]
The present invention relates to the processing technology of backlight, relate in particular to a kind of drain pan of backlight and the method for glue frame integrated through injection molding moulding.
[background technology]
At present, the glue frame and the drain pan of backlight are separated from each other, and assemble after glue frame and drain pan complete respectively, because glue frame and drain pan are assemblings each other, therefore, need the glue frame to have higher intensity, impact resistance to be eager to excel; Simultaneously, the thickness of glue frame has requirement, and for too thin glue frame, its intensity is difficult to support the LGP of backlight.
[summary of the invention]
The objective of the invention is to overcome backlight in the prior art to its glue frame need higher intensity, the thickness of glue frame can not approach a kind of preparation method that improves the structure of glue frame intensity that deficiency provides excessively simultaneously.
The present invention realizes through following technical scheme: the method for a kind of backlight drain pan and the moulding of glue frame integrated through injection molding, and it may further comprise the steps:
S1, through punch press with the drain pan punch forming;
S2, stamping forming drain pan among the SI placed in the die cavity of mould of the injection machine that is used for the mould-injection frame;
S3, in the mould cavity of mould-injection frame, inject sizing material, beginning mould-injection frame, and make glue frame and said drain pan take shape in one.
Do further to set forth in the face of above step down:
Preferably, said S2 step may further comprise the steps:
The safety door of S201, the said injection machine of unlatching;
S201, die cavity light source place is aimed at the light source place of said drain pan, made the smooth applying of drain pan put into die cavity.
Further preferably, said S3 step may further comprise the steps:
The parameter of S301, adjustment glue frame moulding on said injection machine;
S302, in said injection machine, inject sizing material;
S303, startup injection moulding with the injection mo(u)lding of glue frame, and make glue frame and said underframe take shape in one.
Beneficial effect of the present invention is: one of which, this method are with the drain pan and the moulding of glue frame integrated through injection molding of backlight, and by this, the glue frame depends on the support of drain pan, make that its anti-ability of falling is stronger, and impact resistance is stronger.
Two, since with the moulding of drain pan integrated through injection molding, by the support of drain pan, can make thinner that the glue frame makes, saved material, satisfied the characteristics that the backlight needs are made thinlyyer simultaneously.
Three, with drain pan and the moulding of glue frame integrated through injection molding, saved the later stage glue frame to be assembled to the manpower on the drain pan through manual work, also improved production efficiency simultaneously.
[description of drawings]
Fig. 1 is a block flowsheet sketch map of the present invention.
[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further described:
With reference to shown in Figure 1, the method for backlight drain pan of the present invention and the moulding of glue frame integrated through injection molding, it may further comprise the steps:
The first step, through punch press with the drain pan punch forming;
The safety door of second step, the said injection machine of unlatching;
The 3rd step, die cavity light source place is aimed at the light source place of said drain pan, made the smooth applying of drain pan put into die cavity;
The parameter of the 4th step, adjustment glue frame moulding on said injection machine;
The 5th the step, in said injection machine, inject sizing material;
The 6th step, startup injection moulding with the injection mo(u)lding of glue frame, and make glue frame and said underframe take shape in one.
With glue frame and the moulding of drain pan integrated through injection molding, by this, the glue frame depends on the support of drain pan through said method, makes that its anti-ability of falling is stronger, and impact resistance is stronger; Secondly, since with the moulding of drain pan integrated through injection molding, by the support of drain pan, can make thinner that the glue frame makes, saved material, satisfied the characteristics that the backlight needs are made thinlyyer simultaneously; In addition, with drain pan and the moulding of glue frame integrated through injection molding, saved the later stage glue frame to be assembled to the manpower on the drain pan through manual work, also improved production efficiency simultaneously.
According to the announcement and the instruction of above-mentioned specification, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications more of the present invention and change.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the present invention is not constituted any restriction.
