Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for a plastic button shell. Background Technology

[0002] Plastic button housings are common components in electronic products, mainly used to protect internal circuits and provide a user interface. Stamping is a forming process that uses a press and a die to apply external force to the product to be stamped, causing it to undergo plastic deformation or separation, thereby obtaining stamped parts of the required shape and size.

[0003] When processing plastic keypad shells, stamping is performed. Usually, the keypad shells to be processed are placed sequentially under the stamping mechanism, and the limiting mechanism clamps and positions the keypad shells. Then, the stamping mechanism punches holes in the keypad shells one by one. However, the efficiency of clamping and punching sequentially is low. Therefore, a plastic keypad shell stamping die is proposed. Utility Model Content

[0038] A fixed frame 401 is fixedly connected to the top of the workbench 1 on the other side. A first motor 402 is fixedly installed on one side of the fixed frame 401. A first lead screw 403 is rotatably installed on the other side of the fixed frame 401. A first movable frame 404 is axially slidably connected to the inner side of the fixed frame 401. A second motor 405 is fixedly installed on the outer side of the first movable frame 404. A second lead screw 406 is rotatably installed on the inner side of the first movable frame 404. A guide rod 407 is fixedly connected to the inner side of the first movable frame 404. A second movable frame 408 is radially slidably connected to the outer wall of the guide rod 407. This structural design allows the output shaft of the first motor 402 in operation to drive... The first lead screw 403 is rotated, and the rotating first lead screw 403 drives the first movable frame 404 to slide along the fixed frame 401. The moving first movable frame 404 adjusts the axial position of the positioning mechanism 3 and the plastic key shell to be positioned. By starting the second motor 405, the output shaft of the running second motor 405 drives the second lead screw 406 to rotate. The rotating second lead screw 406 drives the second movable frame 408 to slide along the guide rod 407. The moving second movable frame 408 adjusts the radial position of the positioning mechanism 3 and the plastic key shell to be positioned, and the adjustment range covers the entire processing area of ​​the stamping mechanism 2.

[0039] The output shaft end of the first motor 402 is fixedly connected to the first lead screw 403, and the first moving frame 404 is connected to the first lead screw 403 through a set of lead screw seats.

Placement groove 306 is opened on the surface of the second movable frame 408. Half gear 307 is rotatably assembled on the top of the second movable frame 408. The above structural design allows the plastic button shell to be processed to be placed into the placement groove 306 of the positioning mechanism 3 in sequence. Then, the hydraulic cylinder 301 is started, causing the piston of the running hydraulic cylinder 301 to move. The rod extends and pushes the movable plate 302 to slide axially. The connecting shaft 303 at the top of the movable plate 302 moves synchronously with the movable frame, causing the inclined connecting rod 304 to swing. One end of the connecting rod 304 is slidably connected to the connecting shaft 303, and the other end is hinged to the rotating shaft of a half gear 307, converting linear motion into rotational motion. When a half gear 307 rotates, it drives the adjacent half gears 307 to rotate synchronously in opposite directions through tooth meshing, and all half gears 307 rotate at the same angle, ensuring that the clamping plate 305 fixed on the side of the half gear 307 moves towards or away from the center synchronously.

[0043] In one preferred embodiment, the movable plate 302 is fixedly connected to the output end of the hydraulic cylinder 301, and the output end of the hydraulic cylinder 301 after being energized is used to drive the movable plate 302 to move.

[0045] In one preferred embodiment, the connecting rod 304 is inclined, and the moving plate 302 in the moving state is used to drive the connecting rod 304 to swing through the connecting shaft 303. The above structural design enables the clamping plate 305 in the rotating state to clamp the plastic key shell to be processed in the placement groove 306, and achieves the effect of multi-station synchronous clamping or loosening.

[0046] In one preferred embodiment, the placement groove 306 is used to place the button housing to be processed inside. The above structural design makes the size of the placement groove 306 match the housing, restricting displacement in the Z direction and forming three-dimensional positioning.

[0047] The working principle of this utility model is as follows: First, the operator places the plastic key shell to be processed into the placement groove 306 of the positioning mechanism in sequence. Then, the hydraulic cylinder 301 is started, so that the piston rod of the hydraulic cylinder 301 in the running state extends and pushes the moving plate 302 to slide axially. The connecting shaft 303 at the top of the moving plate 302 moves synchronously with the moving plate 302, which drives the inclined connecting rod 304 to swing. One end of the connecting rod 304 is slidably connected to the connecting shaft 303, and the other end is hinged to the rotating shaft of a half gear 307, converting linear motion into rotational motion. When a half gear 307 rotates, it drives the adjacent half gears 307 to rotate synchronously in opposite directions through tooth meshing, and the rotation angle of all half gears 307 is the same, ensuring that the clamping plate 305 fixed on the side of the half gear 307 moves towards or away from the center synchronously. Then, the clamping plate 305 in the rotating state clamps the plastic key shell to be processed in the placement groove 306, and achieves the effect of multi-station synchronous clamping or loosening.

[0048] By starting the first motor 402, the output shaft of the running first motor 402 drives the first lead screw 403 to rotate. The rotating first lead screw 403 drives the first moving frame 404 to slide along the fixed frame 401. The moving first moving frame 404 adjusts the axial position of the positioning mechanism 3 and the plastic key shell to be positioned. By starting the second motor 405, the output shaft of the running second motor 405 drives the second lead screw 406 to rotate. The rotating second lead screw 406 drives the second moving frame 408 to slide along the guide rod 407. The moving second moving frame 408 adjusts the radial position of the positioning mechanism 3 and the plastic key shell to be positioned, and the adjustment range covers the entire processing area of ​​the stamping mechanism 2.
