Detailed Implementation

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1 Combination Figures 1 to 5 The multi-point forming mold press head assembly shown includes a support 1, a large press head 3, and small press heads 15. A large ball head 2 is provided at the upper end of the support 1. A first spherical groove 4 is provided at the lower end of the upper press head 3. A first opening 5 is provided on one side of the first spherical groove 4, allowing the large ball head 2 to be inserted into the first spherical groove 4 through the first opening 5. Multiple small press heads 15 are provided, with one end of each small press head 15 detachably embedded in the large press head 3, and the multiple small press heads 15 are swayably positioned at the upper end of the large press head 3. In this embodiment, the large press head 3 can be positioned between the first spherical groove 4 and the large ball head 15. With the cooperation of 2, it swings. At the same time, the large pressure head 3 is disassembled and assembled on the large ball head 2 through the first spherical groove 4, so that the large pressure head 3 can be disassembled and assembled independently. Moreover, a small pressure head 15 that can swing is also provided at the upper end of the large pressure head 3, so that the entire pressure head assembly can be adjusted at multiple points, which can better adapt to the pressing of different curved products, increase the contact area, and reduce the wrinkles that occur after pressing the product. At the same time, the small pressure head 15 can also be disassembled and assembled independently, making the replacement of the entire pressure head assembly more convenient, simple to operate, time-saving and labor-saving. The whole structure is simple and compact, and the maintenance cost is relatively lower.

[0034] It is worth noting that in this embodiment, the outer wall of the large pressure head 3 is hemispherical, the upper surface of the support 1 is arc-shaped, and the upper end face of the small pressure head 15 is circular.

[0035] Specifically, in this embodiment, a first limiting block 7 is inserted and installed in the first opening 5. The first limiting block 7 has a first arc-shaped surface 17 at one end facing the first spherical groove 4, so that the first arc-shaped surface 17 and the first spherical groove 4 enclose and form a circular groove. The first limiting block 7 limits the large ball head 2 to prevent the large pressure head 3 from detaching from the large ball head 2. At the same time, the circular groove formed by the enclosed space allows the large pressure head 3 to swing and adjust its position better on the large ball head 2.

[0036] In this embodiment, the inner walls of the first opening 5 are provided with first through holes 6 on both sides, and the first limiting block 7 is provided with third through holes 16 on both sides corresponding to the first through holes 6. The first through holes 6 and the third through holes 16 are connected by first bolts 8 passing through them. The first limiting block 7 is further fixed in the large pressure head 3 by the first bolts 8 to prevent the first limiting block 7 from being pushed out during the pressing process and causing the large pressure head 3 to detach. The structure is more compact and stable. Moreover, the first limiting block 7 can be taken out after the first bolts 8 are removed during disassembly, which saves time and effort in disassembly and assembly.

[0037] In this embodiment, the lower ends of the multiple small pressure heads 15 are provided with small ball heads 12, and the large pressure head 3 is provided with multiple second spherical grooves 9. A second opening 10 is provided on one side of the multiple second spherical grooves 9, so that the small ball heads 12 can be inserted into the second spherical grooves 9 through the second opening 10. The multiple small pressure heads 15 can also be disassembled and assembled individually from the second opening 10, so that each pressure head involved in pressing can be replaced individually. Moreover, the multiple small pressure heads 15 can also be swung and adjusted at their angles individually, so as to better adapt to different curved surface products and achieve better pressing effect.

[0038] The second opening 10 is fitted with a second limiting block 13. The end of the second limiting block 13 facing the second spherical groove 9 is provided with a second arc-shaped surface 19. The second spherical groove 9 and the second arc-shaped surface 19 enclose each other to form a circular groove. The second limiting block 13 limits the small ball head 12 to prevent the small pressure head 15 from detaching from the second spherical groove 9. At the same time, the circular groove formed by the enclosed space allows the small ball head 12 to swing and adjust its position better.

[0039] The second opening 10 has second through holes 11 on both sides of its inner wall, and the second limiting block 13 has fourth through holes 18 on both sides. The second through holes 11 and the fourth through holes 18 are connected by second bolts 14. The second limiting block 13 is further fixed in the second spherical groove 9 by the second bolts 14 to prevent the small pressure head 15 from being pushed out and detached during the pressing process. The overall structure is more compact and stable, and the disassembly and assembly are time-saving and labor-saving.

[0040] It is worth noting that the lower end of the support 1 in this embodiment is provided with a positioning post 23; the positioning post 23 can be inserted and installed on the lifting module of the equipment. The lifting module end is also provided with a corresponding insertion slot, which makes it easy for the positioning post 23 to be inserted into the insertion slot and fixed with screws, so that the large pressure head 3 and the small pressure head 15 can be disassembled and installed separately on the lifting module, saving time and effort.

[0041] Example 2 See Figure 6 and Figure 7 As shown, the difference between this embodiment 2 and embodiment 1 is that the lower part of the large pressure head 3 is provided with a first inclined surface 20, and the upper surface of the support 1 is provided with a corresponding second inclined surface 21; during the pressing process, after the large pressure head 3 swings to the maximum stroke or angle, the first inclined surface 20 can press against the second inclined surface 21 to improve the support force.

[0042] Example 3 See Figure 8 As shown, the difference between this embodiment 3 and embodiment 1 is that the outer wall of the support 1 is quadrilateral, the upper end face of the large pressure head 3 is quadrilateral, the upper end face of the small pressure head 15 is circular, and the upper end face of the small pressure head 15 is provided with a protruding post 22.

[0043] In some other embodiments, the outer wall of the support 1 can be a quadrilateral, or a polygonal shape such as a triangle or pentagon. Similarly, the upper end face of the large pressure head 3 and the upper end face of the small pressure head 15 can also be a triangle, pentagon or other polygonal shape.

[0044] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
