[0004] In actual production, since the gap between the mold core M and the inner wall of the hole is too small, it is difficult to avoid the side wall of the mold core M from contacting the material strip, and the contact will cause wear on the mold core M. Damage to the mold core M will cause burrs on the side of the product, and replacing the mold core M will increase production costs ( Figure 4 The dotted area in the figure is the position where the mold core M contacts the product);
[0005] At present, the a area of the LED bracket allows the existence of burrs, while the b area has strict requirements and does not allow the appearance of burrs.

[0040] Fig.19 One of the electroplating areas F of the strip body is shown in FIG. DETAILED DESCRIPTION
[0041] The LED electrode sheet strip includes a strip body 1, and the strip body 1 has a graphic area for injection molding. It is characterized in that the graphic area includes a first hollow part 1a and a second hollow part 1b that are interconnected, and the second hollow part 1b is used to shape the fluid during the injection molding process. The first hollow part 1a is penetrated by a mold core, and the mold core 2 and the second hollow part 1b constitute a mold cavity.
[0042] The present invention improves the structure of the material strip, thereby changing the use of the mold core on the material strip. Two hollow parts are provided on the material strip body 1. The first hollow part 1a is used for the mold core 2 to pass through, and the second hollow part 1b is used to shape the fluid. That is to say, the second hollow part 1b is used only for the injection fluid to pass through, and the mold core 2 does not need to pass through the second hollow part 1b additionally, thereby avoiding the contact between the mold core 2 and the second hollow part 1b, thereby solving the problem of high cost caused by replacing the mold core 2.
[0043] Furthermore, the second hollow portion 1b includes a group of symmetrical L-shaped second hollow portions 100, wherein the second hollow portion 100 includes a first extension area 1b-1, and the first extension area 1b-1 is to form a first molded part 3a located outside the main body of the LED bracket 3 on the side of the LED bracket 3.
[0044] Furthermore, the second hollow portion includes a first hollow portion 101 located between two second hollow portions 100, wherein the first hollow portion 101 is a linear shape, and a second extension area 1b-2 is provided on the edge area of the first hollow portion 101. The second extension area 1b-2 is for shaping the injection fluid so that a second molded part 3b located outside the main body of the LED bracket 3 is formed on the side of the LED bracket 3.
[0045] Furthermore, there are multiple graphic areas, and there are folding areas 4 (such as Fig.11 The portion selected by the frame in the figure) is used to connect with the LED bracket 3.
[0046] An LED bracket 3 includes a main body and an LED electrode sheet arranged on the main body. A protrusion is also provided on the main body, which is protruded on the outer side of the main body and is located between an upper mold core 21 and a lower mold core 22, and is used to be embedded in the second hollow part of the material strip body 1. The LED electrode sheet is a connecting sheet 11.
[0047] Furthermore, the outer side of the body includes an inclined wall 31 , and the protruding parts are distributed at the corners 32 of the body or on the inclined wall 31 .
[0048] Furthermore, the outer side of the body includes an inclined wall 31 , and the protruding parts are distributed at the corners 32 of the body and on the inclined wall 31 .
[0049] Furthermore, the protrusion includes a first molded part 3a and a second molded part 3b, and the first molded part 3a and the second molded part 3b are respectively matched with the first expansion area 1b-1 and the second expansion area 1b-2 in the second hollow part.
[0050] The design of the traditional LED bracket 3 limits the design and function of the hollow part of the material strip. The new LED bracket 3 improves its structure and newly designs the first molded part 3a and the second molded part 3b, so that in the entire production process, the step of the core 2 entering the second hollow part (the area b referred to in the background technology) is eliminated. Therefore, this new design of the LED bracket 3 saves a lot of production costs, reduces the number of core molds 2 used, and further reduces the requirements for the core mold 2.
[0051] The preparation process of LED bracket 3 is as follows:
[0052] S1, stamping is performed on the material strip body 1 in advance, and a plurality of graphic areas are formed on the material strip body 1 by stamping;
[0053] S2, electroplating on the strip body 1, the electroplating area is Fig.19 Select the F area in the middle.
[0054] S3 (such as Figure 15-16 As shown in the figure, the strip body 1 is placed into the mold. After the mold is closed, the first molding part 21a of the upper mold core 21 passes through the first hollow part 1a, the second molding part 21b is located above the second hollow part 100 and the first hollow part 101, and the third molding part 22a is located below the strip body 1. After the plastic fluid is injected, the plastic fluid forms a corresponding shape along the first molding part 21a and the third molding part 22a. At the same time, the plastic fluid also flows from the first hollow part 1a to the second hollow part 100 and the first hollow part 101;
[0055] S4, after demoulding, the folding foot area 4 is cut so that a bendable connecting piece 11 (such as Fig.12 shown);
[0056] S5, bend the connecting piece 11 to connect the connecting piece 11 to the LED bracket 3 (such as Fig.13 as shown).
[0057] It should be noted that this preparation method can also optimize the electroplating process, such as Fig.13 The contact surface 200 shown does not need to be electroplated, but in the preparation process of the prior art, nickel and silver layers exist on the contact surface 200. Therefore, the present invention also optimizes the electroplating process and reduces the loss of nickel and silver.
[0058] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
