[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0030] As shown in the attached Figures 1 to 2 The in-mold labeling of the reel includes a mold device 1 and a second template assembly 5. The mold device 1 is used for molding plastic products.

[0031] The template device 4 is arranged inside the mold device 1.

[0032] The label device 13 is arranged on the template device 4. The label device 13 is provided with a guiding hole 401, a shaping groove 402 and a label 403. The label 403 is located above the inner wall of the shaping groove 402. The guiding hole 401 guides and shapes the label 403 and is formed simultaneously with the plastic product.

[0033] Among them: before injection molding, the template device 4 and the second template assembly 5 are in a separated state at this time. Then, the manipulator takes out the label on the loading plate beside the injection molding machine and puts the label into the label cavity in the mold by means of electrostatic adsorption. Then, after the template device 4 and the second template assembly 5 are clamped, the injection liquid enters through the injection of the top plate assembly 2 into the shaping groove 402 of the template device 4. After the injection liquid is shaped along the shaping convex block 10 above the second template assembly 5, the outer shell 12 is restricted to be formed. At this time, the label 403 is pressed against the outer surface of the outer shell 12, so as to realize the integrated forming of label sticking and injection molding. Embodiment 2

[0034] On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working modes, as Figures 1 to 8 shown, see the following description for details:

[0035] As a preferred embodiment, the mold device 1 includes a top plate assembly 2, an injection plate assembly 3, a template device 4, a second template assembly 5, a support plate assembly 6 and a base 7. The injection plate assembly 3 is arranged below the top plate assembly 2. The injection plate assembly 3 is provided with a template device 4 on the side far away from the top plate assembly 2. The template device 4 is provided with a second template assembly 5 on the side far away from the injection plate assembly 3. Two groups of support plate assemblies 6 are arranged on the side far away from the second template assembly 5. Two groups of support plate assemblies 6 are provided with a base 7 on the side far away from the second template assembly 5.

[0036] As a preferred embodiment, a guiding hole 401 is provided at the top of the template device 4, and shaping grooves 402 are provided above the inner walls of the template device 4. A label 403 is attached to the upper part of the inner wall of the shaping groove 402. When the injection liquid enters the injection separation plate through the injection hole 8, the injection separation plate injects the injection liquid into the shaping groove 402 of the template device 4 along the guiding hole 401. The label 403 is placed into the shaping groove 402 of the template device 4 by a manipulator. When the label 403 comes into contact with the injection liquid, the metal material property of the label itself makes it not easily deformed, so that the label 403 can better adhere to the outer surface of the housing 12.

[0037] As a preferred embodiment, an injection hole 8 is provided at the top of the top plate assembly 2, and connection holes 201 are provided on both sides of the injection hole 8. The injection hole 8 is the starting position for the injection liquid to enter the mold device 1. Therefore, the injection liquid enters the mold through the injection hole 8 for shaping.

[0038] As a preferred embodiment, placing grooves 302 are provided on both sides of the inner wall of the injection plate assembly 3, and two groups of fixing holes 303 are provided on both sides of the injection plate assembly 3. First lifting columns 301 are provided on the side away from the injection plate assembly 3 of the two groups of fixing holes 303. An injection flow dividing plate 9 is placed on both sides of the inner wall of the placing groove 302. A second lifting column 601 is provided below the two first lifting columns 301. The placing groove 302 provided in the injection plate assembly 3 is used to support and fix the injection plate assembly 3 while placing the injection separation plate, so as to reduce the diversion and leakage of the injection liquid. The injection plate assembly 3 is in contact with the first lifting column 301 through the fixing hole 303. Therefore, when placing and taking the injection plate assembly 3, it is convenient to take the injection plate assembly 3.

[0039] As a preferred embodiment, a convex template 14 is placed above the second template assembly 5, an injection convex block 10 is provided above the convex template 14, and a housing 12 is placed above the injection convex block 10. The second template assembly 5 is used to place the convex template 14, and the injection convex block above the convex template 14 is used in cooperation with the shaping groove 402 to realize the space for injecting the housing 12. Through the cooperation of the second template assembly 5 and the convex template 14, the structure of the convex template 14 can be replaced at any time according to actual needs.

[0040] As a preferred embodiment, positioning holes 11 are provided on the four sides of the top plate assembly 2, the injection molding plate assembly 3, the template device 4, the second template assembly 5, the support plate assembly 6 and the base 7. At this time, when installing the top plate assembly 2, the injection molding plate assembly 3, the template device 4, the second template assembly 5, the support plate assembly 6 and the base 7, the positioning holes 11 of the plate body can be connected to the connecting columns above the base 7, so as to complete the restriction of the plate body.

[0041] As a preferred embodiment, the support plate assembly 6 is provided with a second lifting column 601, and the second lifting column 601 is located on one side of the support plate assembly 6.

[0042] The working process of the present utility model is as follows: First, place the base 7 of the mold device 1 at the designated position, then place two groups of support plate assemblies 6 above the base 7, then place the second template assembly 5 above the support plate assemblies 6, and then place the convex template 14 above the second template assembly 5 according to actual needs. After placing the convex template 14, place the label 403 above the inner wall of the shaping groove 402 of the template device 4 through a manipulator, and then combine the template device 4 and the second template assembly 5. At this time, place the injection molding splitter plate 9 inside the placement groove 302 of the injection molding plate assembly 3, and then place the injection molding plate assembly 3 and the top plate assembly 2 in sequence. After completion of the placement, the injection molding liquid enters the injection molding splitter plate 9 through the injection hole 8 of the top plate assembly 2, and the injection molding liquid is split by the injection molding splitter plate 9, so that the injection molding liquid enters the two shaping grooves 420 respectively. At this time, after the injection molding liquid is restricted by the shaping convex block 10 and the shaping groove 402 and molded, the injection molding liquid contacts the label 403, and when the injection molding liquid solidifies to form the outer shell 12, the label 403 adheres to the outer surface of the outer shell 12, thereby realizing an integrated structure of label pasting and shaping. The above is the working principle of in-mold labeling of this reel.

[0043] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
