[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: See Figures 1 to 6A high-efficiency silicone button molding device includes: a molding table 1, a lower mold base 11 is detachably mounted on the molding table 1, a plurality of molding grooves 111 are opened on the upper end of the lower mold base 11, and a separation push plate 41 is slidably mounted in each molding groove 111, a molding frame 12 is mounted on the molding frame 12, and a lifting electric cylinder 13 is mounted on the molding frame 12. The telescopic end of the lifting electric cylinder 13 passes through the molding frame 12 and is fixed with a lifting seat 15. The upper end of the molding frame 12 is also slidably inserted. There is a lifting guide rod 14, the lower end of which is fixedly connected to the upper end of a lifting base 15, and the lower end of the lifting base 15 is detachably mounted with an upper mold base 16; a fixing mechanism 2, mounted on the forming table 1, is used to fix the lower mold base 11 to the forming table 1; a connecting mechanism 5, mounted between the lifting base 15 and the upper mold base 16, is used to fix the upper mold base 16 to the lower end of the lifting base 15; and a separating mechanism 3, mounted on the lower end of the forming table 1, is used to separate the molded silicone keypad from the lower mold base 11. In this embodiment, a heating wire is provided in the upper mold base 16, which softens the silicone sheet through the upper mold base 16, thereby facilitating the molding of the silicone keypad.

[0024] The working principle of the present invention: During specific use, first install the upper mold base 16 to the lower end of the lifting base 15 through the connecting mechanism, then install the lower mold base 11 to the upper end of the forming table 1 through the fixing mechanism 2, then place the silicone sheet on the lower mold base 11, then push the upper mold base 16 downward through the lifting electric cylinder 13, and the silicone sheet can be hot-pressed into the shape of a button by cooperating with the upper mold base 16 and the lower mold base 11. After the hot pressing is completed, the formed silicone button can be separated from the lower mold base 11 through the separation mechanism 3, without manual separation, which can effectively improve the processing efficiency.

[0025] As a further solution, the fixing mechanism 2 includes a pair of fixing seats 21 installed on the upper end of the forming table 1, and each of the fixing seats 21 is installed with a fixed electric cylinder 22. The telescopic end of the fixed electric cylinder 22 passes through the fixing seat 21 and is installed with a fixed splint 23. The opposite side of the fixed splint 23 is installed with a fixing protrusion 24, and the left and right sides of the lower mold base 11 are provided with fixing grooves 25 corresponding to the fixed protrusions 24.

[0026] The working principle of the fixing mechanism 2 is as follows: when fixing, the lower die base 11 is first placed in the middle of the forming table 1. Then, the fixing electric cylinders 22 on both sides extend, pushing the fixing clamps 23 on both sides toward each other, thereby clamping the lower die base 11. At the same time, the fixing protrusions 24 on the fixing clamps 23 extend into the corresponding fixing grooves 25, further positioning the lower die base 11 and improving the fixing effect. The installation of the fixing mechanism 2 for the lower die base 11 facilitates disassembly and allows the selection of a different lower die base 11 for installation according to actual needs.

[0027] As a further solution, the connecting mechanism 5 includes a connecting slot 51 provided at the lower end of the lifting seat 15, and a connecting block 52 is installed at the corresponding position on the upper end of the upper mold seat 16. The connecting block 52 is inserted into the corresponding connecting slot 51. The connecting block 52 and the lifting seat 15 have connecting holes 54 provided at corresponding positions, and a connecting pin 53 is inserted into the connecting hole 54. In this embodiment, the connecting block 52 is T-shaped, and the connecting slot 51 is adapted to the connecting block 52.

[0028] The working principle of the connecting mechanism 5 is: when connecting, insert the connecting block 52 on the upper mold base 16 into the corresponding connecting slot 51, and wait until the connecting block 52 is fully inserted into the connecting slot 51. At this time, insert the connecting pin 53 into the connecting hole 54 to complete the installation of the upper mold base 16. The operation is simple and it is convenient to disassemble and replace the upper mold base 16.

[0029] As a further solution, the separation mechanism 3 includes a separation electric cylinder 31 installed at the lower end of the forming table 1. The telescopic end of the separation electric cylinder 31 passes through the forming table 1 and is fixed with a separation lifting plate 33. The lower end of the forming table 1 is also slidably inserted with a separation guide rod 32. The upper end of the separation guide rod 32 is fixedly connected to the lower end of the separation lifting plate 33. The lower end of the lower mold base 11 is provided with a separation hole 112 corresponding to the position of each forming groove 111, and the upper end of the separation lifting plate 33 is extended with a separation column 34 corresponding to the position of each separation hole 112.

[0030] The working principle of the separation mechanism 3 is: when it is necessary to separate the molded silicone button from the lower mold base 11, the separation electric cylinder 31 extends, pushing the separation lifting plate 33 upward, so that the separation column 34 at the upper end of the separation lifting plate 33 is inserted into the corresponding separation hole 112, thereby pushing the separation push plate 41 upward, and the silicone button in the molding groove 111 of the lower mold base 11 can be pushed out, thereby separating the silicone button from the lower mold base 11. No manual separation is required, which can effectively improve processing efficiency and better meet usage requirements.

[0031] As a further solution, a reset mechanism 4 is also installed at the lower end of the separation push plate 41. The reset mechanism 4 includes a pair of reset guide rods 42 installed at the lower end of the separation push plate 41. The lower ends of the reset guide rods 42 pass through the lower mold base 11 and are fixed with a reset end cover 43. A reset spring 44 is also mounted on the reset guide rod 42. The two ends of the reset spring 44 are respectively connected to the reset end cover 43 and the corresponding side of the lower mold base 11.

[0032] The working principle of the reset mechanism 4 is: when the separation column 34 pushes the separation push plate 41 to move upward, the reset spring 44 is compressed. When the separation column 34 is reset, the reset spring 44 recovers and drives the separation push plate 41 to reset, which is convenient for subsequent processing.
