[0026] The clamping mechanism 10 includes an insert rod 101, a top plate 102, a spring 103 and a push plate 104. The insert rod 101 is movably connected to the inside of the lower fixed block 4. The upper end of the insert rod 101 passes through the inner wall of the lower fixed block 4 and extends into its connecting groove 7. The top plate 102 is fixedly connected to the lower end of the insert rod 101. The spring 103 is arranged below the top plate 102. The push plate 104 is slidably connected to one side of the surface of the lower fixed block 4. The upper side of the push plate 104 passes through the lower fixed block 4 and is fixedly connected to the insert rod 101.

[0027] Through the above technical solution, by setting up the clamping mechanism 10, the push plate 104 is pushed to drive the insertion rod 101 to move downward, overcoming the force of the spring 103, and the insertion rod 101 is retracted to the inside of the lower fixed block 4, so that the staff can disassemble the lower mold 8 conveniently.

[0028] Specifically, one end of the threaded rod 11 passes through the inner wall of the lower fixed block 4 and is rotatably connected thereto, one end of the threaded rod 11 is fixedly connected to a crank 13, the diameter of the crank 13 is larger than the diameter of the threaded rod 11, and a bearing seat 14 is provided inside the lower fixed block 4, the bearing seat 14 is fixedly connected to the other end of the threaded rod 11, and the other end of the bearing seat 14 is embedded and fixed in the inner wall of the lower fixed block 4.

[0029] Through the above technical solution, by setting the crank 13, an effective force point can be provided when rotating the threaded rod 11, so that the staff can easily rotate the threaded rod 11. By setting the bearing seat 14, the other end of the threaded rod 11 can be fixed to prevent the threaded rod 11 from shaking violently during rotation, thereby increasing the stability of the threaded rod 11 during rotation.

[0030] Specifically, sliding grooves 16 are provided on both sides of the upper part of the lower fixed block 4 , and sliding blocks 17 are fixedly connected to both ends of the lower part of the L-shaped positioning plate 12 . The sliding blocks 17 are slidably connected to the lower fixed block 4 through the sliding grooves 16 .

[0031] Through the above technical solution, by setting the sliding groove 16 and the sliding block 17, the L-shaped positioning plate 12 can be guided when it moves, preventing the L-shaped positioning plate 12 from shifting in position when moving, causing the raw material plate to shift in the placement position.

[0032] Specifically, one side of the upper side of the insertion rod 101 is set as an inclined surface, and the movable stroke of the insertion rod 101 is greater than the length of the insertion rod 101 extending into the connecting groove 7.

[0033] Through the above technical solution, by setting the upper side of the insertion rod 101 as an inclined surface, due to the flow guidance of the inclined surface, when installing the lower mold 8, the lower part of the lower mold 8 is aligned with the connecting groove 7 on the lower fixed block 4 and pushed hard. At this time, the lower part of the lower mold 8 will conflict with the upper end of the insertion rod 101. Under the flow guidance of the inclined surface, the insertion rod 101 can be pushed into the inside of the lower fixed block 4, so as to install the lower mold 8.

[0034] Specifically, a placement groove 15 is provided inside the upper fixing block 5 , and a clamping mechanism 10 is provided inside the upper fixing block 5 through the placement groove 15 . The inner height of the L-shaped positioning plate 12 is the same as the height of the lower mold 8 .

[0035] Through the above technical scheme, placement grooves 15 are opened inside the upper fixed block 5, and the upper fixed block 5 is provided with a clamping mechanism 10 inside through the placement grooves 15, so that the upper mold 9 can be replaced quickly and conveniently. The inner height of the L-shaped positioning plate 12 is the same as the height of the lower mold 8. When placing the raw material plate, the raw material plate will not be lifted by the L-shaped positioning plate 12 due to the existence of the L-shaped positioning plate 12, which affects the pressing effect of the device on the raw material plate.

[0036] Specifically, one end of the threaded rod 11 is set to have a clockwise thread, and the other end of the threaded rod 11 is set to have a counterclockwise thread.

[0037] Through the above technical solution, when the threaded rod 11 is rotated, through the above setting, the two L-shaped positioning plates 12 above the lower fixed block 4 can move simultaneously and the moving distance is the same. At the same time, under this action and the action of the L-shaped positioning plate 12 to position the raw material plate, the center position of the raw material plate can be placed at the center point of the lower mold 8 and the upper mold 9.

[0038] Working principle: When in use, first select the correct pressing mold, then the staff then drives the insertion rod 101 to move downward by pushing the push plate 104, overcomes the force of the spring 103, and retracts the insertion rod 101 to the inside of the lower fixed block 4. At this time, the old mold is taken out, and then the push plate 104 is released. At this time, the threaded rod 11 is driven to rotate by turning the crank 13, so that the threaded rod 11 can drive the L-shaped positioning plate 12 to move, and the position can be adjusted according to the lateral size of the new mold. Then, the bottom of the new mold is aligned with the connecting groove 7 on the lower fixed block 4 and pushed hard. At this time, the bottom of the new mold will conflict with the upper end of the insertion rod 101, and under the guiding effect of the inclined surface, the insertion rod 101 can be pushed to the inside of the lower fixed block 4. Thus, the new mold is installed. When installing the upper mold, the old mold is also disassembled through the clamping mechanism 10, and then the mold is installed. After the installation is completed, since the size of the raw materials is mostly larger than the size of the mold, the threaded rod 11 is driven to rotate by turning the crank 13 again, so that the threaded rod 11 drives the L-shaped positioning plate 12 to move. The position of the L-shaped positioning plate 12 can be moved laterally according to the size of the raw material plate. In this way, the raw material plate can be simply positioned under the action of the L-shaped positioning plate 12. After the position adjustment of the L-shaped positioning plate 12 is completed, the raw material plate is then placed between the L-shaped positioning plates 12, and the hydraulic cylinder 3 is started to drive the upper fixed block 5 to move the upper mold 9 to press the raw material plate.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
