[0022] 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.

[0023] Please see Figure 1-9 This utility model provides the following technical solution: a pressing device for a replaceable printing mold, including a worktable 1, a printing mold 2, and a clay frame 3. The worktable 1 is provided with a pressing device, which includes a pressing cylinder 4, a displacement cylinder 5, a slider 6, and a slide rail 7. The pressing cylinder 4 is connected to the worktable 1 via a bracket 8. The pressing cylinder 4 is connected to the printing mold 2 via a quick-release assembly. The displacement cylinder 5 is connected to the side wall of the worktable 1. The slide rail 7 is connected to the top surface of the worktable 1. The slider 6 is slidably connected to the slide rail 7. The clay frame 3 is connected to the slider 6. The worktable 1 has a fitting groove 9 adapted to the slider 6. The push rod of the displacement cylinder 5 passes through the side of the worktable 1 and is connected to the slider 6. The side wall of the worktable 1 is provided with a controller 10 and a switch button 11. The controller 10 is connected to the switch button 11, the pressing cylinder 4, and the displacement cylinder 5 via wires.

[0024] In the above structure, a pressing cylinder 4 and a displacement cylinder 5 are set to realize the automated control of the pressing action and the displacement of the clay frame 3, thereby improving production efficiency; the quick-release component facilitates the replacement of the printing mold 2 to meet different printing needs; the slide rail 7 and the slider 6 work together to make the clay frame 3 move smoothly, the fitting groove 9 ensures the precise movement of the slider 6, and the controller 10 and the switch button 11 are easy to operate, realizing convenient control of the device.

[0025] In this embodiment, the quick-release assembly includes a support plate 12, a locking block 13, a threaded guide post 14, a threaded ring 15, and a movable claw 16. The support plate 12 has a guide post channel 17 adapted to the threaded guide post 14. The threaded guide post 14 is slidably connected in the guide post channel 17. The printing mold 2 is connected to the locking block 13. The threaded guide post 14 has a locking groove 18 adapted to the locking block 13. The support plate 12 is provided with a retaining ring 19. The threaded ring 15 is movably connected to the outer wall of the retaining ring 19 and threadedly connected to the threaded guide post 14. The support plate 12 is connected to the push rod of the pressing cylinder 4 through the movable claw 16.

[0026] In the above structure, when the printing mold 2 needs to be replaced, the threaded ring 15 is rotated, and the threaded guide post 14 is driven to move smoothly up and down within the guide post channel 17 using the transmission principle of the thread. After the locking block 13 of the printing mold 2 is aligned with the engaging groove 18 of the threaded guide post 14 and inserted, the threaded ring 15 is rotated again to move the threaded guide post 14 upward. At this time, the locking block 13 is lifted into the guide post channel 17, thereby firmly fixing the printing mold 2 onto the support plate 12. During disassembly, the threaded ring 15 is rotated in the opposite direction to move the threaded guide post 14 downward, and the locking block 13 disengages from the guide post channel 17, allowing the printing mold 2 to be easily removed. This operation method greatly simplifies the replacement process of the printing mold 2, significantly shortens the replacement time, allows the production line to quickly switch between different printing styles, and greatly improves the flexibility and efficiency of production. The tight fit between the locking block 13 and the locking groove 18 can effectively resist various external forces during the pressing process, ensuring that the printing mold 2 is installed firmly and will not shift or loosen; the movable claw 16, with its reliable connection structure, ensures that the support plate 12 and the pressing cylinder 4 push rod are always tightly connected, stably transmitting the pressing power and ensuring the smooth progress of the entire pressing operation.

[0027] In this embodiment, the movable claw 16 includes a first claw body 20 and a second claw body 21. The second claw body 21 is connected to the first claw body 20 by bolts. The support plate 12 has a positioning groove 22 that is adapted to the second claw body 21.

[0028] With the above structure, the movable claw 16 adopts a split design, with the first claw body 20 and the second claw body 21 connected by bolts, which facilitates installation and disassembly, and makes it convenient to maintain and replace the movable claw 16. The positioning groove 22 is adapted to the second claw body 21, so that the movable claw 16 is installed more accurately on the support plate 12, improving the stability of the connection between the support plate 12 and the push rod of the pressing cylinder 4, and ensuring the reliability of the entire pressing process.

[0029] In this embodiment, a cavity 23 is provided in the middle of the first claw body 20, and the threaded guide post 14 is located in the cavity 23.

[0030] By adopting the above structure, the cavity 23 avoids interference between the first claw body 20 and the threaded guide post 14, making the structure more compact and reasonable, providing sufficient space for the movement of the threaded guide post 14, ensuring the normal operation of the quick-release assembly, and improving the overall performance of the device.

[0031] In this embodiment, the end of the second claw body 21 away from the first claw body 20 is connected to a displacement block 24 by bolts, and the displacement block 24 is engaged in the positioning groove 22.

[0032] With the above structure, the displacement block 24 and the positioning groove 22 are engaged by a snap-fit ​​connection, and the displacement block 24 is firmly connected to the second claw body 21 by bolts. This design greatly enhances the stability of the connection between the movable claw 16 and the support plate 12. In actual operation, when it is necessary to adjust the position of the movable claw 16, the operator only needs to turn the bolt, and the displacement block 24 can be easily moved up and down by utilizing the screw drive principle of the bolt.

[0033] In this embodiment, the support 8 has an adjacent entrance 25 on the side facing the mud frame 3.

[0034] With the above structure, when the size of the mud frame 3 is long, the mud frame 3 can extend beyond the worktable 1 through the inlet 25, breaking through the size limitation of the worktable 1. This makes the device applicable to the processing needs of mud frames 3 of different specifications, effectively expanding the scope of use of the equipment and improving its versatility and practicality.

[0035] In this embodiment, a preset box 26 is connected to the side wall of the bracket 8, and the opening of the preset box 26 is connected to the adjacent entrance 25.

[0036] Using the above structure, the pre-set box 26 loads the portion of the mud frame 3 that extends out of the worktable 1 from the adjacent inlet 25.

[0037] Working principle: The operator sends a command to the controller 10 via the switch button 11 on the workbench 1. The controller 10 then controls the pressing cylinder 4 and the displacement cylinder 5 accordingly. The displacement cylinder 5 pushes the slider 6 to slide on the slide rail 7, causing the connected clay frame 3 to move. The pressing cylinder 4 is fixed to the workbench 1 via the bracket 8 and performs pressing upon receiving the command. When changing the printing mold 2, the threaded ring 15, which is threaded to the threaded guide post 14, is rotated. The threaded transmission causes the threaded guide post 14 to move up and down within the guide post channel 17 of the support plate 12. After inserting the printing mold 2 locking block 13 into the locking groove 18 of the threaded guide post 14, the threaded ring 15 is rotated to move the threaded guide post 14 upward and fix the printing mold 2. Rotating in the opposite direction allows it to be removed. The movable claw 16 consists of a first claw body 21 connected by bolts. The second claw body 21 is connected to the displacement block 24 and snapped into the positioning groove 22 of the support plate 12. The bolts enhance the connection stability and allow for position adjustment. The cavity 23 in the middle of the first claw body 20 avoids interference with the threaded guide post 14. When the clay frame 3 is long, it can extend out of the worktable 1 through the inlet 25 of the bracket 8. The pre-set box 26 on the side wall of the bracket 8 is connected to the inlet 25 and is used to load the extended part to accommodate the processing of clay frames 3 of different specifications.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
