DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Reference Figures 1-4 A novel computer keyboard forming die, including workbench 1, workbench 1 is installed with L type connecting plate 2, L type connecting plate 2 is installed with stamping device 3, workbench 1 is installed with lower mould 4, and push plate 5 is slidably connected in lower mould 4, and the bottom of push plate 5 is connected with the output shaft of first air cylinder 6, and first air cylinder 6 is installed in the inside of workbench 1, and servo motor 7 is installed on L type connecting plate 2, and the output shaft of servo motor 7 is connected with bidirectional screw rod 8, and two moving rods 9 are screw-connected on bidirectional screw rod 8, and two moving rods 9 are slidably connected with clamping plate 10, and two second air cylinders 11 are installed on workbench 1, and the output end of two second air cylinders 11 is installed with connecting strip 12, and two clamping plates 10 are slidably connected on corresponding connecting strips 12.

[0022] When producing the die, first, the solution in the lower mould 4 is stamped by the stamping device 3, so that the die is formed, after the die is cooled, the stamping device 3 is controlled to return to the initial position, then the push plate 5 is driven upward by the first air cylinder 6, the formed die is ejected from the lower mould 4, then the servo motor 7 is started, the bidirectional screw rod 8 is driven to rotate by the servo motor 7, so that the two moving rods 9 are close to each other, so that the two clamping plates 10 clamp the die, then the two connecting strips 12 are driven to move outward by the two second air cylinders 11, so as to drive the clamping plate 10 and the die to move to the outside of the lower mould 4, then the servo motor 7 is controlled to rotate reversely, so that the two clamping plates 10 are away from each other, so that the die falls, so as to complete the demolding process of the die.

[0023] Specifically, in the embodiment, two connecting blocks 13 are mounted on the L-shaped connecting plate 2, the servo motor 7 is mounted on one of the connecting blocks 13, and the bidirectional screw rod 8 is rotatably connected between the two connecting blocks 13. The connecting blocks 13 can provide a mounting base for the servo motor 7 and ensure the rotational connection of the bidirectional screw rod 8, so that the servo motor 7 can drive the bidirectional screw rod 8 to rotate synchronously.

[0024] Specifically, in the embodiment, a limiting groove 14 is formed on the L-shaped connecting plate 2, and a first limiting block 15 is mounted on one end of each of the two moving rods 9 close to the L-shaped connecting plate 2. The first limiting block 15 is slidably fitted in the limiting groove 14, so that the two moving rods 9 can be slidably connected to the L-shaped connecting plate 2 through the fitting of the first limiting block 15 and the limiting groove 14. Thus, when the bidirectional screw rod 8 drives the two moving rods 9 to move, the two moving rods 9 can only move along the direction of the limiting groove 14, so that the two moving rods 9 can move closer to or away from each other.

[0025] Specifically, in the embodiment, a sliding groove 16 is formed at the bottom end of each of the two moving rods 9, and the top of each of the two clamping plates 10 is slidably fitted in the corresponding sliding groove 16. Thus, the clamping plate 10 can be slidably connected to the moving rod 9, so that when the two second air cylinders 11 are activated, the two clamping plates 10 can move synchronously with the moving direction of the second air cylinders 11, thereby achieving the purpose of moving the molded mold to the outside of the lower mold 4.

[0026] Specifically, in the embodiment, the distance between the two clamping plates 10 is less than the distance between the two moving rods 9, so that when the two moving rods 9 drive the two clamping plates 10 to move closer to each other synchronously, the two clamping plates 10 can contact the molded mold before the moving rods 9, thereby achieving the purpose of clamping the molded mold by the clamping plates 10.

[0027] Specifically, in the embodiment, a connecting shaft 17 is mounted at the bottom of each of the two clamping plates 10, and a connecting groove 18 is formed in each of the two connecting strips 12. The two connecting shafts 17 are slidably fitted in the corresponding connecting grooves 18, so that the clamping plate 10 can be slidably connected to the connecting strip 12 through the connecting shaft 17. When the two clamping plates 10 move closer to each other, the clamping plates 10 can always maintain the connection relationship with the connecting strip 12 while moving, so that the clamping plates 10 can move downwardly to the outside of the lower mold 4 while clamping the molded mold, thereby assisting the demolding work.

[0028] Specifically, in the embodiment, two second limiting blocks 19 are installed on the workbench 1, and the output shafts of the two second cylinders 11 are slidingly connected to the corresponding second limiting blocks 19, so that the output shafts of the second cylinders 11 are always connected to the second limiting blocks 19 when moving outward, thereby limiting the moving direction of the second cylinders 11 by the second limiting blocks 19, so as to avoid the moving direction of the connecting strips 12 connected to the second cylinders 11 from deviating.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
