[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0024] Please refer to Figures 1 to 5 As shown, it shows the specific structure of the preferred embodiment of the utility model, which is a rubber plug assembly jig.

[0025] The lower template 30 is provided with a plug needle 31 for inserting a plug 36, the middle template 20 is provided with a cavity 21 for placing a product 22, and an opener 40 is provided between the middle template 20 and the lower template 30. The worker inserts the plug 36 into the plug needle 31, and the product 22 is placed in the cavity 21. After the upper template 10 and the middle template 20 are closed together, the upper template 10 and the middle template 20 continue to move toward the lower template 30, and the plug needle 31 accurately inserts the plug 36 into the product 22, which improves the assembly efficiency of the plug 36, reduces labor costs, and ensures better assembly quality.

[0026] The present application provides a plug assembly jig, including an upper template 10, a middle template 20, and a lower template 30; the lower template 30 is provided with a plug needle 31; the middle template 20 is provided with a cavity 21; an opener 40 is provided between the middle template 20 and the lower template 30; the upper template 10 and the middle template 20 can be closed in the lower template 30; the plug needle 31 penetrates the cavity 21 and inserts the plug 36 into the product 22. A plugging portion 38 is formed on the top of the needle body 37 of the plug needle 31, and the plug 36 is inserted into the plugging portion 38. The middle template 20 is provided with an avoidance hole for avoiding the plug needle 31, and the plug needle 31 can extend into the cavity 21 from the avoidance hole. Preferred working steps: 1. The worker inserts the plug 36 into different plug needles 31 and puts the product 22 into the cavity 21 at the same time. 2. The upper template 10 and the middle template 20 move toward the lower template 30 at the same time. Under the action of the shutter 40, the upper template 10 and the middle template 20 are closed together first (that is, there is still a certain margin between the middle template 20 and the lower template 30, which can prevent the plug needle 31 from ejecting the product 22 in the cavity 21), and then the upper template 10 and the middle template 20 continue to move toward the lower template 30. 3. After the upper template 10, the middle template 20, and the lower template 30 are completely closed, the plug needle 31 accurately inserts the plug 36 into the product 22. 4. When opening the mold, the upper template 10 and the middle template 20 move toward the upper template 10 at the same time. Under the action of the shutter 40, the upper template 10 will first separate from the middle template 20. When the upper template 10 moves to a certain height, the middle template 20 will separate from the lower template 30. This design can prevent the product 22 from jumping in the cavity 21, which is conducive to ensuring the accuracy of installing the plug 36. The length of the plug needle 31 is preset, and when the plug needle 31 extends into the cavity 21, the plug needle 31 can accurately insert the plug 36 into the product 22. It can be seen that the assembly jig of the plug 36 not only improves the assembly efficiency of the plug 36, but also reduces the labor cost, and the assembly quality is more guaranteed.

The arc-shaped protrusion 44 of the clamping column 41 is slightly larger than the size of the limiting groove 43. When the upper template 10 and the middle template 20 move toward the lower template 30, the protrusion will first be stuck in the limiting groove 43, so that a part of the gap will be left between the middle template 20 and the lower template 30. When the upper template 10 is pressed on the middle template 20, the upper template 10 and the middle template 20 will continue to move downward, so that the plug needle 31 penetrates into the cavity 21, and then the plug needle 31 can penetrate the plug 36 into the screw hole of the product 22.

[0028] Preferably, the distance between the bottom of the clamping column 41 and the protrusion is between 5-15 mm, such as 6 mm, 8 mm, 10 mm, 12 mm, and 14 mm. These distances can adapt to the depth of the cavity 21, have better adaptability, and can prevent the plug needle 31 from ejecting the product 22 from the cavity 21 before the plug 36 is inserted.

[0029] Preferably, the lower template 30 is arranged on the lower mold base; the upper template 10 is arranged on the upper mold base 11; the lower template 30 is provided with a first guide column 35, and the upper template 10 is provided with a second guide column 13, the first guide column 35 can be inserted into the middle template 20, and the second guide column 13 can pass through the middle template 20 and the lower template 30. When the upper template 10, the middle template 20, and the lower template 30 are molded together, the first guide column 35 can be inserted into the first guide column 35 hole of the middle template 20, and the second guide column 13 can pass through the second guide column 13 holes of the middle template 20 and the lower template 30. This design is conducive to ensuring the accuracy of the upper template 10, the middle template 20, and the lower template 30 when the mold is closed, and avoiding deviation.

[0030] Preferably, the lower mold base includes a bottom plate 32, a vertical plate 33, and a support plate 34, the lower mold plate 30 is arranged on the support plate 34, and the vertical plate 33 is arranged between the bottom plate 32 and the support plate 34. The lower mold plate 30 is arranged on the support plate 34, and the lower mold plate 30 is suspended at a certain height, so that sufficient activity space can be reserved for the limit rod 12 and the second guide column 13.

[0031] Preferably, a limit rod 12 is provided between the upper template 10 and the middle template 20, and the limit rod 12 can move up and down on the middle template 20. The upper end of the limit rod 12 is fixed to the upper template 10 by a thread, and the lower end of the limit rod 12 can movably pass through the middle template 20. When the upper template 10 moves upward, the limit rod 12 can lift the middle template 20.

[0032] Preferably, the lower template 30 is provided with a first sensor 23, which can be triggered by the middle template 20; the middle template 20 is provided with a second sensor 39, which can be triggered by the upper template 10.
