A jig lower mold core 4 is provided on the end face, and a jig lower mold movable block 19 and a product 3 are provided inside and outside the jig lower mold core 4 respectively. A second through hole 28 is provided on the product 3, and a clamping edge 27 is provided on the inner wall of the second through hole 28. The upper end of the jig lower mold movable block 19 passes through the jig lower mold core 4 and the product 3 and is connected with a ring buckle 16. A protective film is installed on the ring buckle 16. A jig upper mold core 5 and a cylinder 2 are provided on the outer shell 36 above the ring buckle 16. The jig upper mold core 5 is fixedly connected to the working rod of the cylinder 2.

[0024] The upper mold core 5 of the jig includes a first mold base, a first mold core 9, a first adjusting block 10, a second adjusting block 11 and a protrusion 6. The upper end surface of the first mold base is fixedly connected to the working rod of the cylinder 2. The lower end surface of the first mold base is provided with a first groove. The first mold core 9, the first adjusting block 10 and the second adjusting block 11 are provided on the first groove. The position of the first mold core 9 can be adjusted by changing the placement of the first adjusting block 10 and the second adjusting block 11. The first mold core 9 is provided with a protrusion 6 to facilitate the die pressing and film laminating operation. The protrusion 6 is provided with a first column hole 12 and a second column hole 13 of the same size as the first through hole 14 and the second through hole 15 to facilitate the coordinated operation of the first through hole 14 and the second through hole 15.

[0025] The first mold core 9, the first adjusting block 10 and the second adjusting block 11 are connected to the first mold base by bolts to facilitate movement and adjustment.

[0026] The jig lower mold movable block 19 includes a first positioning column 21, a second positioning column 20, a first base 31, a column 32 and a spring 23. The upper end surface of the first base 31 is provided with a column 32. The first base 31 and the column 32 are integrally formed. The upper end surface of the column 32 is provided with a first positioning column 21 and a second positioning column 20. The sizes of the first positioning column 21 and the second positioning column 20 are respectively smaller than the first through hole 14 and the second through hole 15, so that the first positioning column 21 and the second positioning column 20 can pass through the first through hole 14 and the second through hole 15. The lower end surface of the first base 31 is provided with two column cavities 22. A spring 23 is arranged in the column cavity 22. The elastic force of the spring 23 is used to eject the product 3 assembled with the buckle 16 and the protective film, which saves time and labor and has high production efficiency.

The upper end surface of the second mold core 34 is provided with a second groove 24. The center of the second groove 24 is provided with a first through hole 26. The size of the first through hole 26 is smaller than the size of the ring buckle 16 to prevent the ring buckle 16 from falling into the interior of the jig lower mold core 4 from the first through hole 26. The second grooves 24 on both sides of the first through hole 26 are provided with third grooves 25, so that the limit block 18 can be against the third groove 25, so that the ring buckle 16 is not excessively pressed downward to damage the buckle 17. The shape of the second mold core 34 is the same as that of the product 3 and its size is smaller than that of the product 3, which is convenient for the product 3 to be installed on the second mold core 34.

[0028] The front end of the operating table 30 is provided with a cylinder 2 operating button to facilitate operation.

[0029] A pressure gauge 29 is also provided at the front end of the operating table 30, so as to know at any time whether the gas source for providing power to the cylinder 2 is sufficient, and to provide the gas source to the cylinder 2 in time without affecting the production efficiency.

[0030] A shock-absorbing foot pad 7 is provided on the lower end surface of the operating table 30 to reduce vibrations generated during operation and prevent the jig mold frame 1 from vibrating and moving significantly.

[0031] A partition plate 35 is provided at the inner upper end near the outer shell 36, and a second through hole 28 is provided on the partition plate 35. The area of ​​the second through hole 28 is smaller than the area of ​​the jig upper mold core 5. The working rod of the cylinder 2 passes through the second through hole 28 and is fixedly connected to the jig upper mold core 5. While fixing the jig upper mold core 5, it can also prevent excessive operation of the cylinder 2 from causing the jig upper mold core 5 to collide with the outer shell 36 and damage the outer shell 36 and the cylinder 2.

[0032] The working principle of embodiment 1 of the present invention is:

[0033] like Figure 1-6As shown, first, the product 3 is installed on the jig lower mold core 4. At this time, the upper end of the jig lower mold movable block 19 passes through and exceeds the jig lower mold core 4 and the product 3. Then, the buckle 16 and the protective film are installed on the upper end of the jig lower mold movable block 19 through the first positioning column 21 and the second positioning column 20, that is, the buckle 16 and the protective film are at the upper end of the second perforation 28 and the clamping edge 27 of the product 3. Then, the cylinder 2 operating button is pressed to start the cylinder 2, so that the cylinder 2 drives the jig upper mold core 5 to move downward. After that, the first positioning column 21 and the second positioning column 20 extend into the first column hole 12 and the second column hole 13, so that the protrusion 6 presses the buckle 16 and the protective film downward toward the product 3, and finally the buckle 17 of the buckle 16 is clamped on the clamping edge 27, so that the buckle 16 and the protective film are fixedly connected to the product 3, and then the cylinder 2 moves upward. Due to the elastic force of the spring 23, the movable block 19 of the lower mold of the jig moves upward and pushes the product 3 out of the lower mold core 4 of the jig, and finally the product 3 is taken out to complete one operation.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] A first positioning column 21 and a second positioning column 20 are provided, so that the buckle 16 and the protective film can be quickly installed on the jig lower mold movable block 19 and the jig lower mold core 4; buckles 17 and limit blocks 18 are provided on the front and rear sides of the lower end surface of the bottom of the ring buckle 16 plate, so that the buckle 16 is fixedly connected to the product 3 to ensure the quality of the product 3; the operating rod of the cylinder 2 is fixedly connected to the jig upper mold core 5, and the ring buckle 16 and the protective film are quickly installed on the product 3 through the operation of the cylinder 2, which reduces labor intensity and improves work efficiency.

[0036] The above are only preferred embodiments of the present invention, and the patent protection scope of the present invention is not limited thereto. Any equivalent structural transformations made using the contents of the present invention's specification and drawings, directly or indirectly used in other related technical fields, are also included in the protection scope of the present invention.
