Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a punching device for producing silica gel buttons. Background Art

[0002] Keypads are an integral component of many products. Silicone keypads and silicone keypad covers are particularly popular for specialized products requiring waterproof and dustproof protection due to their superior performance. The production of these silicone keypads typically involves stamping silicone sheets to form the desired key shape or keypad cover.

[0003] Traditional stamping equipment typically consists of two upper and lower molds, which cooperate to form the silicone material. During this process, the silicone sheet must fit tightly within the mold holes to accurately stamp into the desired shape. However, after stamping, traditional methods require workers to manually remove the keys from the mold holes. This method not only reduces production efficiency but also, due to the uncertainty of manual operation, can easily cause some keys to deform or damage, thereby increasing the defective product rate.

[0004] Based on this, in order to solve the above-mentioned technical defects, a stamping device for producing silicone buttons is proposed. Utility Model Content

The bidirectional threaded rod is symmetrically rotatably connected to the upper side of the stamping device body, the movable plate is threadedly connected between the left sides of the bidirectional threaded rod, and the bottom of the movable plate is connected to the soft brush. The stamping device body is provided with a drive assembly for driving the soft brush to move.

[0009] It is further explained that the soft brush is located above the stamping seat and its width is adapted to the stamping seat.

[0010] Further explanation: the drive assembly includes a connecting frame, a ratchet bar, a spring II and a ratchet gear. The connecting frame is symmetrically connected to the top of the stamping device body. Ratchet bars are slidingly connected on both sides of the connecting frame.

[0022] Example: A stamping device for producing silicone buttons, such as Figures 1-4 As shown, it includes a bracket 1, a punching device body 2, a punching seat 3, a cylinder 4, a punching plate 5, a punching head 12, a cutter 13, a top plate 7, a connecting rod 8, a spring Ⅰ 9, a connecting plate 10 and a guide rod 11. The bottom of the punching device body 2 is symmetrically connected to the bracket 1, the middle part of the punching device body 2 is connected to the punching seat 3, the upper side of the punching device body 2 is installed with a cylinder 4 by a bolt, the cylinder 4 is connected to the punching plate 5 on the telescopic rod, a plurality of punching holes 6 are evenly opened in the punching seat 3, a plurality of punching heads 12 are evenly connected to the bottom of the punching plate 5, and the bottom of the punching plate 5 is located at a position outside the punching head 12. The punching head 12 is aligned with the punching hole 6, and the two are slidably matched. The punching hole 6 is slidably connected with a connecting rod 8, and the top of the connecting rod 8 is connected to a top plate 7 for ejecting the finished button. The punching head 12 is in contact with the top plate 7. The left and right sides of the bottom of the punching seat 3 are symmetrically welded with guide rods 11, and connecting plates 10 are slidably connected between the guide rods 11. The connecting rod 8 passes through the bottom of the punching seat 3 and is connected to the connecting plate 10. The spring I9 is ​​sleeved on the lower end of the connecting rod 8, and the upper and lower ends of the spring I9 are respectively connected to the punching seat 3 and the connecting plate 10.

[0023] like Figure 1 、 Figure 5 and Figure 6As shown, it also includes a bidirectional threaded rod 18, a movable plate 19, a soft brush 20 and a drive assembly. The bidirectional threaded rod 18 is symmetrically connected to the front and back of the upper side of the stamping device body 2. The movable plate 19 is threadedly connected between the left sides of the bidirectional threaded rod 18. The bottom of the movable plate 19 is connected to a soft brush 20 for unloading the keys. The soft brush 20 is located above the stamping seat 3, and its width is adapted to the stamping seat 3. The stamping device body 2 is provided with a drive assembly for driving the soft brush 20 to move.

[0024] like Figure 1 、 Figure 5 and Figure 6 As shown, the drive assembly includes a connecting frame 14, a ratchet bar 15, a spring II 16 and a ratchet gear 17. The top of the stamping device body 2 is symmetrically connected to the connecting frame 14 by bolts. The ratchet bars 15 are slidably connected to the front and rear sides of the connecting frame 14. Multiple springs II 16 are connected between the ratchet bar 15 and the connecting frame 14. Ratchet gears 17 are welded to the left and right ends of the bidirectional threaded rod 18, and the ratchet gear 17 is engaged with the ratchet bar 15.

[0025] like Figure 1 As shown, it also includes a collection frame 21 and a handle 22. The collection frame 21 for collecting silicone buttons is slidably connected to the lower side of the stamping device body 2, and the handle 22 is symmetrically welded on the front side of the collection frame 21.

[0026] When the key is stamped, first place the silicone block on the stamping seat 3 so that it covers the stamping hole 6, then start the cylinder 4, the telescopic rod of the cylinder 4 extends to drive the stamping plate 5, the stamping head 12 and the cutter 13 to move downward, and at the same time drive the connecting frame 14 and the ratchet bar 15 to move downward, the ratchet bar 15 contacts the ratchet gear 17, and the tooth angle direction of the two is not matched. The ratchet gear 17 will push the ratchet bar 15 to move repeatedly inside and outside, and the spring II 16 will deform, so that the ratchet bar 15 will not mesh with the ratchet gear 17, and the stamping head 12 will move down and contact the silicone block. The rubber block contacts and applies pressure to the silicone block through the punching head 12, which can punch the silicone block into the punching hole 6 and fit the shape of the punching hole 6. At the same time, it pushes the top plate 7, the connecting rod 8 and the connecting plate 10 to move downward, and the spring I9 is ​​compressed accordingly. During the stamping process, the cutter 13 is located on the outer contour of the punching hole 6, which can cut off the stamped silicone button and the corners to form a single silicone button. After the stamping is completed, the telescopic rod of the cylinder 4 retracts and returns to its original position and closes. The telescopic rod drives the stamping plate 5, the punching head 12 and the cutter 13 to move upward. The punching head 12 is separated from the inside of the punching hole 6, and the silicone button and the top plate 7 are no longer under force. The spring II 16 will rebound and reset, thereby driving the top plate 7, the connecting rod 8 and the connecting plate 10 to move upward. The top plate 7 will push the silicone button in the punching hole 6 to the surface of the punching seat 3. When the punching plate 5 moves upward, it also drives the connecting frame 14 and the ratchet bar 15 to move upward. The tooth angle of the ratchet bar 15 corresponds to that of the ratchet gear 17, and the two are engaged. The ratchet bar 15 drives the ratchet gear 17 to rotate, and then drives the bidirectional threaded rod 18 to rotate, so that it can The movable plate 19 and the soft brush 20 move to the right, and the soft brush 20 will push the buttons on the stamping seat 3 to the right, so that the buttons fall into the collection frame 21. When they move to the right side to the end point, the connecting frame 14 and the ratchet bar 15 also stop moving. When the next round of button stamping is performed, the bidirectional threaded rod 18 rotates again, which will move the movable plate 19 and the soft brush 20 to the left, thus realizing a left-right rotation movement. After finishing the work, pull the handle 22 by hand to pull out the collection frame 21, and the silicone buttons inside can be taken out.
