Description

Technical Field

[0001] This utility model relates to the field of keyboard base plate processing technology, and in particular to a keyboard base plate leveling mold. Background Technology

[0002] When manufacturing keyboard base plates, the process of punching key holes causes the base plate to bend, rendering it unusable and requiring it to be folded back. Traditionally, this is done manually by bending the base plate in the opposite direction to straighten the bend. However, this manual method is inefficient and requires significant force. Insufficient force results in unevenness and continued bending, while excessive force causes the plate to bend in the opposite direction, failing to achieve the required flatness. Therefore, it is necessary to provide a keyboard base plate flattening mold to solve these technical problems. Utility Model Content

[0003] In order to overcome the defects of the prior art, this utility model provides a keyboard base plate leveling mold that provides stable support force when stamping the keyboard base plate. The stamping operation will not cause the keyboard base plate to bend, and there is no need for subsequent leveling operations by hand or with the help of other molds.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A keyboard base plate leveling mold includes: a mold body, the mold body including a cavity plate, the front surface of the cavity plate having multiple through slots, the inside of the through slots having a support piece, a support rod fixedly connected to one side surface of the support piece, a telescopic rod fixedly connected to the surface of the support rod away from the support piece, the other end of the telescopic rod being fixedly connected to the contact surface of the cavity plate, and a compression spring sleeved on the outside of the telescopic rod, the two ends of the compression spring being fixedly connected to the contact surfaces of the cavity plate and the protrusion respectively.

[0006] Preferably, a pair of lugs are fixed to both sides of the cavity plate.

[0007] Preferably, right-angle limiting plates are fixed to the four corners of the front surface of the cavity plate.

[0008] Preferably, the cavity plate is provided with an auxiliary component, which includes: multiple crossbars, all located inside the cavity plate; multiple vertical rods fixed to the bottom of the outer wall of each crossbar; a wedge fixed to the other end of each vertical rod; a groove below the wedge; the groove being formed above the outer wall of the support rod; vertical rods fixed to both ends of each crossbar; protruding rods fixed to the upper and lower ends of the outer wall of each vertical rod; a ball bearing slidably engaged at the other end of each protruding rod; the ball bearing fitting against the inner wall of the cavity plate; a lead screw fixed to the upper outer wall of the top crossbar; a knob threaded onto the outer wall of the lead screw; a sleeve fixed to the bottom of the knob; a vertical cylinder rotatably connected to the bottom of the outer wall of the sleeve; and the vertical cylinder being fixedly connected to the contact surface of the cavity plate.

[0009] Preferably, the center points of the lead screw and the crossbar are on the same horizontal and vertical line.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This utility model utilizes the cooperation between the various components of the mold body. The operator first places the sheet material of the keyboard base plate to be stamped on the surface of the cavity plate. Then, the stamping device is driven to perform the stamping operation, which can stamp the key holes on the sheet material. During this process, the non-through groove part of the cavity plate surface can provide support force to the non-stamped part of the sheet material, so that the plate layer will not bend. There is no need for subsequent manual or other mold leveling operations. During the stamping, the compression spring is compressed and deformed. After the punch in the stamping device moves up, the compression spring rebounds, and the support plate moves to push out the waste material generated after stamping, so that the next stamping and forming operation can proceed smoothly.

[0012] (2) Through the cooperation between the mold body and the auxiliary components, when the waste material generated during the stamping process is stuck on the inner wall of the through groove and cannot be pushed out by the spring force, the user can apply force to turn the knob. Due to the threaded connection between the knob and the lead screw, the horizontal bar, the vertical bar and the inclined block can move towards each other. During this period, the inclined block slides deeper into the inclined groove, which can make the support rod and the support plate move towards the surface of the cavity plate. This can facilitate the pushing out of the waste material stuck in the through groove, and make the overall structure of the mold run stably and smoothly. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0020] Example 1: As Figures 1-5 As shown, this utility model provides a keyboard base plate leveling mold, comprising: a mold body, the mold body including a cavity plate 1, the front surface of the cavity plate 1 having multiple through grooves 2, the inside of the through grooves 2 having a support piece 3, the support piece 3 and the through groove 2 having a clearance fit, the clearance fit being a fit with a gap (including a minimum gap equal to zero), a support rod 4 fixedly connected to one side surface of the support piece 3, a telescopic rod 5 fixedly connected to the surface of the support rod 4 away from the support piece 3, the telescopic rod 5 being composed of a square tube and a square rod, the square rod being located inside the square tube, the square rod being able to slide laterally inside the square tube, which can improve the lateral stability of the support piece 3, the other end of the telescopic rod 5 being fixedly connected to the contact surface of the cavity plate 1, a compression spring 6 being sleeved on the outside of the telescopic rod 5, the coefficient of the compression spring 6 being 2-5 N / CM, the two ends of the compression spring 6 being fixedly connected to the contact surfaces of the cavity plate 1 and the protruding rod 14 respectively.

[0021] Example 2: A pair of lugs 7 are fixedly connected to both sides of the cavity plate 1. The lugs 7 can facilitate the connection between the cavity plate 1 and the surface of the stamping worktable to ensure the stability of the cavity plate 1.

[0022] Example 3: Right-angle limiting plates 8 are fixed to the four corners of the front surface of the cavity plate 1. The right-angle limiting plates 8 can limit the position of the keyboard base plate material.

[0023] Example 4: An auxiliary assembly is provided inside the cavity plate 1. The auxiliary assembly includes: multiple horizontal bars 9, all located inside the cavity plate 1; multiple vertical bars 10 are fixed to the bottom of the outer wall of each horizontal bar 9; a wedge block 11 is fixed to the other end of each vertical bar 10; a groove 12 is provided below the wedge block 11, and the groove 12 is opened above the outer wall of the support rod 4; vertical bars 13 are fixed to both ends of each horizontal bar 9; protruding rods 14 are fixed to both the upper and lower ends of the outer wall of each vertical bar 13; and the other end of each protruding rod 14... A ball bearing 15 is slidably engaged at the end. The ball bearing 15 can roll but cannot be separated from the protruding rod 14. The ball bearing 15 is in contact with the inner wall of the cavity plate 1. A lead screw 16 is fixedly connected to the upper part of the outer wall of the top crossbar 9. A knob 17 is threadedly connected to the outer wall of the lead screw 16. A sleeve 18 is fixedly connected to the bottom end of the knob 17. A vertical cylinder 19 is rotatably connected to the bottom end of the outer wall of the sleeve 18. The sleeve 18 is rotatably connected to the vertical cylinder 19 through a ball bearing. The vertical cylinder 19 is fixedly connected to the contact surface of the cavity plate 1.

[0024] Example 5: The center points of the lead screw 16 and the crossbar 9 are on the same horizontal and vertical line. After rotating the knob 17, the lead screw 16 can be moved, and a uniform force can be applied to the top crossbar 9.

[0025] In use, the operator first installs the cavity plate 1 onto the worktable surface of the stamping device using the lug 7. Then, the sheet material to be stamped (the keyboard base plate) is placed on the surface of the cavity plate 1. Multiple right-angle limiting plates 8 limit the placement of the sheet material. The stamping device is then driven to perform the stamping operation, punching the keyboard key holes on the sheet material. During this process, the non-through groove 2 portion of the cavity plate 1 provides support to the non-stamped portion of the sheet material, preventing bending and eliminating the need for subsequent manual or other mold-based leveling. During stamping, the compression spring 6 is compressed and deformed. After the punch moves up in the stamping device, the compression spring 6 rebounds, and the support plate 3 moves to press the material. The waste material generated is pushed out. During this process, if the waste material is stuck on the inner wall of the through groove 2 and cannot be pushed out by the spring force of the compression spring 6, the user can apply force to rotate the knob 17. Due to the threaded connection between the knob 17 and the lead screw 16, the horizontal bar 9, the vertical bar 10 and the inclined block 11 can move towards each other. During this period, the inclined block 11 slides deeper into the inclined groove 12, which can make the support rod 4 and the support plate 3 move towards the surface of the cavity plate 1. This can facilitate the pushing out of the waste material stuck in the through groove 2, and make the overall structure of the mold run smoothly and stably, so as to facilitate the smooth progress of the next stamping and forming operation.
