Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This embodiment of a car seat back panel stamping die includes a support frame 1. A press 2 is fixedly installed on the inner top wall of the support frame 1. An upper support plate 3 is fixedly connected to the output end of the press 2. A lower die base 14 is provided on the inner bottom wall of the support frame 1. A lower pad 15 is detachably connected to the upper side of the lower die base 14. A lower ejector plate 16 is detachably connected to the upper side of the lower pad 15. A lower template 17 is detachably connected to the upper side of the lower ejector plate 16. An ejector plate 19 is installed inside the lower ejector plate 16. A lower die insert 18 is bolted to the side of the lower template 17. An upper die base 4 is detachably connected to the lower side of the upper support plate 3. A demolding structure is provided on the lower side of the upper die base 4. The demolding structure includes an upper pad 5 bolted to the lower side of the upper mold base 4, an upper clamping plate 6 bolted to the lower side of the upper pad 5, two first punches 10 installed on the lower side of the upper mold base 4, an 8 bolted to the lower side of the upper clamping plate 6, an upper template 9 bolted to the lower side of the 8, four sets of telescopic sliding rods 20 fixedly connected to the lower side of the upper mold base 4, a positioning block 21 fixedly connected to the lower side of the upper template 9, two springs 22 fixedly connected to one side of the positioning block 21, a push block 23 fixedly connected to one side of the spring 22, and a second punch 24 fixedly connected to one side of the push block 23.

[0022] Among them, the upper side of the support frame 1 is fixedly connected to the lower support plate 12, the lower side of the lower mold base 14 is inserted into the upper side of the lower support plate 12, the lower side of the lower mold base 14 is fixedly connected to two lower pads 13, the two lower pads 13 are inserted into the interior of its lower support plate 12, the upper mold base 4 and the upper pad 5 are bolted to the sides of multiple upper clamping plate inserts 7, the upper templates 9 and 8 are bolted to the sides of multiple upper ejector inserts 11, each set of telescopic slide rods 20 is in pairs, the lower side of the telescopic slide rods 20 has a groove structure, the lower template 17 and the lower ejector plate 16 are bolted to the sides of the lower mold inserts 18, the center of the upper template 9 and the lower template 17 has a through groove structure.

[0023] It should be noted that the upper clamping plate insert 7, the upper ejector insert 11, and the lower mold insert 18 are irregular accessories embedded in the mold. Their main function is to fix the template and fill the space between the various parts of the mold. The upper template 9 and the lower template 17 are both fixedly connected with elastic elements, and the elastic elements are strong springs.

[0024] The working principle of the above embodiments is as follows:

[0025] Take out the required back plate mold parts and fix them sequentially on the surfaces of the upper mold base 4 and the lower mold base 14. During this process, the upper clamping plate insert 7, the upper ejector insert 11, and the lower mold insert 18 are used to fix multiple parts together. Start the press 2 to push the upper support plate 3 towards the upper side of the lower mold base 14 and use the first punch 10 to punch the material. At the same time, when the bottom of the telescopic slide rod 20 contacts the lower template 17, it continues to move and contacts the surface of the push block 23, and pushes the second punch 24 from the positioning block 21 to contact and punch the side of the material. The four sets of telescopic slide rods 20 punch the four sides of the material at the same time, which can ensure multi-faceted punching and shaping with the upper template 9 and the lower template 17. After the shaping is completed, the upper mold base 4 and the lower mold base 14 are separated. Then, with the help of the elastic element, the shaped back plate is pushed out of the mold cavity. The lower ejector plate 16 uses the elastic element to push the ejector plate 19 to push out the back plate in the same way.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply.
