The second main plate body 41 is detachably fixedly mounted on the bottom wall of the movable mold 1 close to the fixed mold 2 by bolts, and the second auxiliary plate body 42 is detachably fixedly mounted in the second main plate body 41. A plurality of protrusions 8 are fixedly mounted on the bottom walls of the second main plate body 41 and the second auxiliary plate body 42 close to the fixed mold 2. The plurality of protrusions 8 correspond to the plurality of grooves 7 one by one, and the protrusions 8 are movably inserted in the grooves 7. When the first pressing plate 3 and the second pressing plate 4 are pressed together, the second pressing plate 4 drives the plurality of protrusions 8 to slide and insert in the plurality of grooves 7, so that a plurality of convex bumps can be pressed out on the panel.
[0040] The first main board body 31 is provided with first guide grooves 15 on the top wall close to the movable mold 1 and at both ends of its own diagonal line. The second main board body 41 is provided with first guide columns 16 fixedly installed on the bottom wall close to the fixed mold 2 and at both ends of its own diagonal line. The first guide columns 16 are adapted to be slidably inserted in the first guide grooves 15 along the moving direction of the movable mold 1.

[0044] The first main board body 31 and the second main board body 41 are provided with opening grooves 21 on both sides of the side walls close to each other along the width direction. When the panel is pressed, the two opening grooves 21 on the first main board body 31 correspond to the two opening grooves 21 on the second main board body 41, and the opening grooves 21 are connected to the outside air. When the panel is pressed, the opening grooves 21 on the first main board body 31 and the second main board body 41 are connected to the outside air, so that the first pressing plate 3 and the second pressing plate 4 can be separated easily.
[0045] The grooves 7 and the protrusions 8 on the first main body 31 and the second main body 41 correspond to the keys at the same position in panels of different models of products, and the grooves 7 and the protrusions 8 on the first sub-board 32 and the second sub-board 42 correspond to the keys at different positions in panels of different models of products. When pressing panels of different models, only the first sub-board 32 and the second sub-board 42 at different positions of the keys in the panel need to be replaced to complete the pressing of panels of different models of products, thereby improving the applicability of the pressing mold and reducing the production cost of the panel.
[0046] A first mounting groove 5 is formed in the first main plate body 31 along its thickness direction, and the first auxiliary plate body 32 is slidably mounted in the first mounting groove 5 along the thickness direction of the first main plate body 31.

Eight first elastic members 11 are fixedly installed at intervals on the bottom wall of the first installation groove 5 of the first main plate body 31, and the ends of the eight first elastic members 11 are all against the first limiting ring block 10. In the present application, the first elastic member 11 can be selected as a spring.
[0048] When installing the first sub-plate 32, the first sub-plate 32 is inserted into the first installation groove 5 from the side of the first main plate 31 close to the fixed mold 2. During the insertion and sliding process of the first sub-plate 32, the first limiting ring block 10 is driven to slide into the first limiting ring groove 9. The first main plate 31 is fixedly installed on the fixed mold 2 using bolts. During the installation process, the first sub-plate 32 squeezes the eight first elastic members 11 through the first limiting ring block 10. After the installation is completed, the first elastic member 11 acts on the first sub-plate 32 through the first limiting ring block 10, so that the first sub-plate 32 is pressed against the fixed mold 2, so that the first sub-plate 32 is installed more firmly in the first main plate 31.
[0049] When disassembling the first auxiliary plate 32, the first main plate 31 is removed from the fixed mold 2, and the eight first elastic members 11 release elastic potential energy and push the first auxiliary plate 32 out of the first mounting groove 5 through the first limiting ring block 10, thereby making it more convenient and quick to disassemble the first auxiliary plate 32. By disassembling and replacing the first auxiliary plate 32, the first pressing plate 3 can be adapted to different models of product panels.
[0050] A second mounting groove 6 is formed in the second main plate body 41 along the thickness direction thereof, and the second auxiliary plate body 42 is adapted and slidably mounted in the second mounting groove 6 along the thickness direction of the second main plate body 41. A second limiting ring groove 12 is formed on the top wall of the second main plate body 41 near the movable mold 1, and the second limiting ring groove 12 is connected to the second mounting groove 6 and is located on the outer peripheral side of the second mounting groove 6.
[0051] A second limiting ring block 13 is fixedly installed on one end of the outer peripheral side wall of the second auxiliary plate body 42 close to the movable mold 1, and the second limiting ring block 13 is slidably installed in the second limiting ring groove 12 along the thickness direction of the second main plate body 41. Eight second elastic members 14 are fixedly installed at intervals on the bottom wall of the second installation groove 6 of the second main plate body 41, and the ends of the eight second elastic members 14 are all against the second limiting ring block 13.

[0052] When installing the second sub-plate 42, the second sub-plate 42 is inserted into the second installation groove 6 from the side of the second main plate 41 close to the movable mold 1. During the insertion and sliding process of the second sub-plate 42, the second limiting ring block 13 is driven to slide into the second limiting ring groove 12. The second main plate 41 is fixedly installed on the movable mold 1 using bolts. During the installation process, the second sub-plate 42 squeezes the eight second elastic members 14 through the second limiting ring block 13. After the installation is completed, the second elastic member 14 acts on the second sub-plate 42 through the second limiting ring block 13, so that the second sub-plate 42 is pressed against the movable mold 1, so that the second sub-plate 42 is installed more firmly in the second main plate 41.
[0053] When disassembling the second auxiliary plate 42, the second main plate 41 is removed from the movable mold 1, and the eight second elastic members 14 release elastic potential energy and push the second auxiliary plate 42 out of the second mounting groove 6 through the second limiting ring block 13, thereby making it more convenient and quick to disassemble the second auxiliary plate 42. By disassembling and replacing the second auxiliary plate 42, the second pressing plate 4 can be adapted to different types of product panels.

When pressing panels of different models, only the first sub-board body 32 and the second sub-board body 42 at different positions of the keys in the panel need to be replaced to complete the pressing of panels of different models of products, thereby improving the applicability of the pressing mold and reducing the production cost of the panel.
