During the rotation process, the mounting column 3 drives the mounting block 7 to rotate, so that the mounting block 7 drives the fixed frame 8 to move, so that the positions of the two fixed frames 8 are interchanged, and two groups of symmetrically placed fixed frames 8 and lower molds 81 are set, so that uninterrupted loading and unloading can be achieved, thereby improving the processing efficiency of leather.

[0042] Fixing grooves are provided on both sides of the mounting column 3, and a clamping assembly 5 is installed in the fixing groove. A mounting block 7 is clamped on one side of the clamping assembly 5. The clamping method facilitates the separation of the mounting block 7 from the mounting column 3, thereby facilitating the disassembly of the fixing frame 8 and the lower mold 81. One side of the mounting block 7 is fixedly connected to the fixing frame 8, and the lower mold 81 is slidably connected inside the fixing frame 8. When in use, it is necessary to replace the lower mold 81 with different patterns to perform hot embossing on the leather to meet the diversity of leather patterns, thereby meeting the production needs of the product. In order to facilitate disassembly, a clamping assembly 5, a reinforcing assembly 6 and a driving assembly 4 for controlling the reinforcing assembly 6 and the clamping assembly 5 are set.

[0046] A driving assembly 4 is installed on one side of the No. 1 gear 51. The driving assembly 4 includes a No. 1 gear plate 42. The No. 1 gear plate 42 meshes with the No. 1 gear 51. The upper end of the No. 1 gear plate 42 is fixedly connected to the support plate 41. One side of the support plate 41 is rotatably connected to the turning handle 44. The lower end of the turning handle 44 passes through the support plate 41 to insert the plug rod 43. The driving assembly 4 is used to control the clamping assembly 5 and the reinforcing assembly 6. The lifting and lowering of the No. 1 gear plate 42 can drive the No. 1 gear 51 to rotate, and the plug rod 43 can be inserted into the plug frame 65. The plug rod 43 is driven by the rotation of the turning handle 44, thereby driving the plug frame 65 on one side to rotate.

[0047] A reinforcement assembly 6 is also installed in the fixed groove, and the reinforcement assembly 6 includes two No. 2 threaded rods 61, both of which are rotatably connected to the inner wall of the fixed groove, and the No. 2 threaded rods 61 are fixedly connected to the No. 2 rotating rod 63 on one side close to each other, and the No. 2 threaded rod 61 is threadedly connected to the moving block 62, and the moving block 62 is fixedly connected to the limiting rod 64 on one side, and the limiting rod 64 is plugged into the mounting block 7, and the upper end of the upper No. 2 threaded rod 61 passes through the mounting column 3 and is fixedly connected to the plug-in frame 65. The reinforcement assembly 6 is used to further strengthen the connection between the mounting column 3 and the mounting block 7, and the front and rear side clamping further limits the column mounting block 7 to maintain the stability of the connection of the mounting block 7.

[0048] When in use, the handle 44 can be rotated, the handle 44 drives the insertion rod 43 to rotate, the insertion rod 43 drives the inserted insertion frame 65 to rotate, the insertion frame 65 drives the two No. 2 threaded rods 61 to rotate, so that the No. 2 threaded rod 61 drives the moving block 62 to move, and the moving block 62 drives the limiting rod 64 to move and approach the mounting block 7, so that the limiting rod 64 is inserted into the slot 71 of the mounting block 7.

[0049] The method of clamping the mounting block 7 by the joint action of the clamping assembly 5 and the reinforcing assembly 6 can ensure the stability of the connection between the mounting block 7 and the mounting column 3 and avoid deviation or shaking.

When disassembling and replacing the lower mold, there is no need to disassemble at the lower end of the hot pressing mold machine body 1, making disassembly safer and more convenient.

[0050] When it is necessary to replace the lower mold 81 with a different pattern, the handle 44 can be rotated first, so that the handle 44 drives the insertion rod 43 to rotate, the insertion rod 43 drives the inserted insertion frame 65 to rotate, the insertion frame 65 drives the two No. 2 threaded rods 61 to rotate, so that the No. 2 threaded rod 61 drives the moving block 62 to move, and the moving block 62 drives the limiting rod 64 to move and move away from the mounting block 7, so that the limiting block 64 is no longer plugged into the mounting block 7, and then the handle 44 is pulled to separate the insertion rod 43 from the insertion frame 65, and drive the support plate 41 to move upward. The supporting plate 41 drives the No. 1 gear plate 42 to rise, the No. 1 gear plate 42 drives the No. 1 gear 51 to rotate, the No. 1 gear 51 drives the No. 1 rotating rod 52 to rotate, the No. 1 rotating rod 52 drives the No. 1 threaded rod 53 to rotate, the No. 1 threaded rod 53 drives the clamping plate 54 to move, so that the clamping plate 54 is away from the mounting block 7, and then the mounting block 7 inserted into the mounting column 3 is pulled out, so that the mounting block 7 and the fixed frame 8 on one side are removed together, and then the fixed frame 8 of the lower mold 81 with different patterns can be replaced.

[0051] Embodiment 2

[0052] See also Figure 1 , Figure 2 and Figure 6 , further improvements were made on the basis of Example 1:

[0053] When the leather is undergoing continuous hot embossing, in order to speed up the feeding of the leather and make the continuous leather processing more efficient, a lifting assembly 9 is installed on both sides of the lower mold 81. The lifting assembly 9 includes two fixed blocks 91. One side of the fixed block 91 is fixedly connected to the side wall of the lower mold 81. The fixed block 91 is threadedly connected to a No. 3 threaded rod 92. The upper end of the No. 3 threaded rod 92 is rotatably connected to the side wall of the fixed frame 8. The lower end of the No. 3 threaded rod 92 is fixedly connected to a No. 1 bevel gear 93. One side of the No. 1 bevel gear 93 is meshed with a No. 2 bevel gear 94. One side of the No. 2 bevel gear 94 passes through the side wall of the fixed frame 8 and is fixedly connected to a No. 2 gear 95.

[0054] A pair of second gear plates 10 are symmetrically mounted on the upper end of the annular mounting plate 2. The second gear plates 10 are arc-shaped. Figure 1 shown.

[0055] The specific method of using the hot pressing mold machine in the present invention is as follows: the leather to be hot pressed is placed on the lower mold 81 on the right side of the hot pressing mold machine body 1, and then the servo motor 33 is started, so that the servo motor 33 drives the fourth gear 32 to rotate, the fourth gear 32 drives the third gear 31 to rotate, and the third gear 31 drives the upper end mounting column 3 to rotate half a circle, that is, 180 degrees clockwise. During the rotation process, the mounting column 3 drives the mounting block 7 to rotate, so that the mounting block 7 drives the fixed frame 8 to move, so that the positions of the two fixed frames 8 are interchanged, such as Figure 1As shown, the fixed frame 8 located on the right side is driven to rotate, which drives the leather to move, and makes the No. 2 gear 95 set on both sides of the fixed frame 8 mesh with the No. 2 gear plate 10 on the annular mounting plate 2, so that the No. 2 gear plate 10 drives the No. 2 gear 95 to rotate, and the No. 2 gear 95 drives the No. 2 bevel gear 94 on one side to rotate, the No. 2 bevel gear 94 drives the No. 1 bevel gear 93 to rotate, the No. 1 bevel gear 93 drives the No. 3 threaded rod 92 to rotate, and the No. 3 threaded rod 92 drives the fixed block 91 to move downward, so that the fixed block 91 drives the lower mold 81 to descend and be flush with the upper surface of the fixed frame 8, so that the leather descends, and then the fixed frame 8 continues to be driven by the mounting block 7, driving the lower mold 81 to move to the lower end of the hot pressing mold machine body 1, and then the hot pressing mold machine body 1 is used for hot pressing to emboss the leather surface with patterns.

[0056] When the right fixed frame 8 moves to the lower end of the hot pressing mold machine body 1 on the left, the fixed frame 8 initially located on the left also rotates clockwise, and makes the No. 2 gear 95 mesh with the No. 2 gear plate 10 on the rear portion of the annular mounting plate 2 during the movement, so that the No. 2 gear plate 10 drives the No. 2 gear 95 to rotate, and the No. 2 gear 95 drives the No. 2 bevel gear 94 on one side to rotate, the No. 2 bevel gear 94 drives the No. 1 bevel gear 93 to rotate, the No. 1 bevel gear 93 drives the No. 3 threaded rod 92 to rotate, and the No. 3 threaded rod 92 drives the fixed block 91 to move upward, so that the fixed block 91 drives the lower mold 81 to rise and be higher than the fixed frame 8. When it moves to the right side, a new leather that needs hot pressing can be placed on the surface of the lower mold 81.

[0057] After the left side is processed, the servo motor 33 can be started again to rotate the mounting column 3 counterclockwise half a circle, so that the processed leather is rotated to the right side, and during the rotation process, the leather is lifted up again to separate the leather from the side of the fixed frame 8, so that it is convenient for the staff to peel off the leather that is hot-pressed and stuck from the side, which is conducive to unloading. The newly placed leather is driven by the fixed frame 8 to rotate to the left side, and during the process, the lower mold 81 descends to make the leather descend, and then the hot pressing mold machine body 1 is continued to be used for hot pressing printing.

[0058] By setting up two sets of symmetrically placed fixed frames 8 and lower molds 81, uninterrupted loading and unloading of materials can be achieved, thereby improving the processing efficiency of leather. In the process of the fixed frame 8 driving the lower mold 81 to move to the right side, the second gear plate 10 can be engaged with the second gear 95, so that the lifting assembly 9 can drive the lower mold 81 to rise and fall, so that the lower mold 81 lifts up the leather and separates the leather from the side of the fixed frame 8, thereby making it convenient for the staff to peel off the leather that is hot-pressed and adhered from the side, which is conducive to material unloading.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
