[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic mold for improving the efficiency of computer keyboard painting, comprising a mold frame, and further comprising:

[0006] A fixing mechanism is provided inside the mold frame. The fixing mechanism includes several mold slots provided inside the mold frame. The fixing mechanism is used to install and fix the button in the mold slots to ensure the stability of the button and to facilitate the removal of the button after steam spraying.

[0007] A clamping mechanism is provided inside the mold frame. The clamping mechanism includes several connecting plates disposed inside the mold frame. The clamping mechanism is used to further improve the stability of the button after it is fixed and to prevent it from being loosely installed.

[0008] Preferably, the fixing mechanism includes a plurality of mold slots formed on the mold frame, and L-shaped rectangular limiting rods are fixedly installed on the left inner wall and the right inner wall of the plurality of mold slots respectively. The plurality of L-shaped rectangular limiting rods are arranged in pairs, and the bottom ends of the plurality of groups of L-shaped rectangular limiting rods are fixedly connected to the plurality of mold slots respectively. Strip plates are slidably sleeved on the plurality of groups of L-shaped rectangular limiting rods respectively.

[0009] Preferably, the mold frame has a strip-shaped mounting groove, and a rectangular contact plate is slidably mounted through several strip plates, with the bottom ends of the rectangular contact plates all slidably extending into the strip-shaped mounting groove.

[0010] Preferably, a C-shaped limiting plate is fixedly sleeved on each of the rectangular contact plates, and the strip plates are respectively connected through the C-shaped limiting plates.

[0011] Preferably, two limiting springs are respectively fitted on the plurality of strip plates, and two irregular clamping plates are respectively slidably fitted on the plurality of strip plates. The ends of the plurality of limiting springs that are far apart from each other are respectively fixedly connected to the plurality of irregular clamping plates, and the ends of the plurality of limiting springs that are close to each other are all fixedly connected to the corresponding C-shaped limiting plates.

[0012] Preferably, the clamping mechanism includes an L-shaped fixing plate fixedly installed on one side of several irregularly shaped clamping plates that are close to each other, a strip-shaped hollow block slidingly passing through each of the several L-shaped fixing plates, two connecting plates hingedly installed on each of the several rectangular contact plates, and the ends of the several connecting plates that are far apart from each other are respectively hinged to two strip-shaped hollow blocks.

[0013] Preferably, a return spring is fixedly installed on the inner wall of the side of the plurality of strip hollow blocks that are close to each other, a sliding block is fixedly installed on the side of the plurality of return springs that are far from each other, and a rubber block is fixedly installed on the side of the plurality of sliding blocks that are far from each other.

[0014] Preferably, a plurality of rectangular contact plates are respectively fitted with telescopic springs, the top ends of the plurality of telescopic springs are respectively fixedly connected to a plurality of C-shaped limiting plates, the bottom ends of the plurality of telescopic springs are respectively fixedly connected to a plurality of mold grooves, a connecting rectangular plate is fixedly installed at the bottom end of the plurality of rectangular contact plates, a special-shaped transmission rod is fixedly installed at the bottom of the connecting rectangular plate, a sliding limiting groove is slidably installed in the mold frame, and the special-shaped transmission rod extends into the sliding limiting groove and is slidably connected to the sliding limiting groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model:

[0017] 1. When using, attach the button to the corresponding two i-shaped limiting plates and rectangular contact plate, and then press it down. At this time, the button will contact the irregular clamping plate, and the irregular clamping plates will move closer to each other under the action of their inclined surfaces. At this time, the limiting spring will undergo compression deformation. When the top inner wall of the button contacts the top of the two i-shaped limiting plates, the button will stop descending. At this time, the limiting spring will support the inner wall of the button under the action of elasticity, ensuring that the installation will not slip. When the rectangular contact plate descends with the button, the rectangular contact plate will drive the connecting plate to move, the connecting plate will drive the strip hollow block to move, the strip hollow block will drive the sliding block to move towards the inner wall of the button, and the sliding block will drive the rubber block to contact the inner wall of the button. Since there is a return spring in the strip hollow block, the return spring will undergo compression deformation when the rubber block contacts the inner wall of the button. The elasticity of the return spring will improve the stability of the rubber block on the button. Since the rubber block is made of rubber, it will increase the friction with the inner wall of the button. The friction will ensure that the button is more stable on the device.

[0018] 2. After painting, manually adjust the irregular-shaped drive rod. The drive rod will drive the connecting rectangular plate to rise, which in turn will drive several rectangular contact plates to rise. The rectangular contact plates will then move the connecting plate, causing the rubber block to release its support from the button. As the rectangular contact plates continue to rise, they will push the button out of the irregular-shaped clamping plate, allowing the button to be quickly demolded. The correspondingly early release of the rubber block from the button effectively avoids wear caused by the rubber block when it leaves the button, thus protecting the frictional properties of the rubber block and extending its service life.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-5 The plastic mold shown is for improving the efficiency of computer keyboard spray painting. It includes a mold frame 1 and further includes: a fixing mechanism, which is disposed within the mold frame 1 and includes several mold grooves 101 disposed within the mold frame 1. The fixing mechanism is used to install and fix the keys within the mold grooves 101, ensuring the stability of the keys and facilitating removal of the keys after steam spray painting; and a clamping mechanism, which is disposed within the mold frame 1 and includes several connecting plates 2 disposed within the mold frame 1. The clamping mechanism is used to further improve the stability of the keys after fixing them, preventing insecure installation. The fixing mechanism includes several mold grooves 101 formed on the mold frame 1. L-shaped rectangular limiting rods 102 are fixedly installed on the left and right inner walls of the several mold grooves 101, arranged in pairs. The bottom ends of the several sets of L-shaped rectangular limiting rods 102 are fixedly connected to the several mold grooves 101, and strip plates 103 are slidably sleeved on the several sets of L-shaped rectangular limiting rods 102. The mold frame 1 has a strip-shaped mounting groove 104. Rectangular contact plates 105 are slidably mounted through several strip plates 103, and the bottom ends of the rectangular contact plates 105 extend slidably into the strip-shaped mounting groove 104. C-shaped limiting plates 106 are fixedly fitted onto each of the rectangular contact plates 105, and the strip plates 103 are respectively connected to the C-shaped limiting plates 106. Two limiting springs 108 are fitted onto each of the strip plates 103, and two irregularly shaped clamping plates 107 are slidably fitted onto each of the strip plates 103. The ends of the limiting springs 108 that are far apart from each other are fixedly connected to the C-shaped clamping plates 107, and the ends of the limiting springs 108 that are close together are fixedly connected to the corresponding C-shaped limiting plates 106.

[0027] In use, the button is attached to the two corresponding I-shaped limiting plates 106 and the rectangular contact plate 105, and then pressed down. The button then contacts the irregularly shaped clamping plate 107, which moves closer together due to its inclined surface. At this point, the limiting spring 108 undergoes compression deformation. When the top inner wall of the button contacts the top of the two I-shaped limiting plates 106, the button stops descending. The limiting spring 108, under its elastic force, supports the inner wall of the irregularly shaped clamping plate 107, ensuring the button does not slip. As the rectangular contact plate 105 descends with the button, it will drive the connecting... When the connecting plate 2 moves, it will cause the hollow strip block 110 to move. The hollow strip block 110 will cause the sliding block 202 to move towards the inner wall of the button. The sliding block 202 will cause the rubber block 203 to contact the inner wall of the button. Since the hollow strip block 110 is equipped with a return spring 201, the return spring 201 will undergo compression deformation when the rubber block 203 contacts the inner wall of the button. The elasticity of the return spring 201 will improve the stability of the rubber block 203 on the button. Since the rubber block 203 is made of rubber, it will increase the friction with the inner wall of the button. The friction will ensure that the button is more stable on the device.

[0028] Preferably, the clamping mechanism includes L-shaped fixing plates 109 fixedly mounted on one side of several irregularly shaped clamping plates 107 that are close to each other. A strip-shaped hollow block 110 slides through each of the L-shaped fixing plates 109. Two connecting plates 2 are hinged to each of several rectangular contact plates 105. The ends of the connecting plates 2 that are far apart from each other are hinged to two strip-shaped hollow blocks 110. Return springs 201 are fixedly mounted on the inner walls of the strip-shaped hollow blocks 110 that are close to each other. Sliding blocks 202 are fixedly mounted on the ends of the return springs 201 that are far apart from each other. Rubber blocks 203 are fixedly mounted on the sides of the sliding blocks 202 that are far apart from each other. Several rectangular contact plates 105 are respectively fitted with telescopic springs 204. The top ends of several telescopic springs 204 are respectively fixedly connected to several C-shaped limiting plates 106. The bottom ends of several telescopic springs 204 are respectively fixedly connected to several mold grooves 101. A connecting rectangular plate 205 is fixedly installed at the bottom end of several rectangular contact plates 105. A special-shaped transmission rod 206 is fixedly installed at the bottom of the connecting rectangular plate 205. A sliding limiting groove 207 is slidably installed in the mold frame 1. The special-shaped transmission rod 206 extends into the sliding limiting groove 207 and is slidably connected to the sliding limiting groove 207.

[0029] After painting, manually adjust the irregularly shaped transmission rod 206 upwards. The irregularly shaped transmission rod 206 will drive the connecting rectangular plate 205 to rise, which in turn will drive several rectangular contact plates 105 to rise. The rectangular contact plates 105 will then drive the connecting plate 2 to move, causing the rubber block 203 to release its support from the button. As the rectangular contact plates 105 continue to rise, they will push the button out of the irregularly shaped clamping plate 107, allowing the button to be quickly demolded. The correspondingly earlier release of the rubber block 203 from the button effectively avoids wear caused by the rubber block 203 when it leaves the button, thereby protecting the friction characteristics of the rubber block 203 and extending its service life.

[0030] The working principle of the plastic mold for improving the painting efficiency of computer keyboards provided by this utility model is as follows:

[0031] In use, the button is attached to the two corresponding I-shaped limiting plates 106 and the rectangular contact plate 105, and then pressed down. The button then contacts the irregularly shaped clamping plate 107, which moves closer together due to its inclined surface. At this point, the limiting spring 108 undergoes compression deformation. When the top inner wall of the button contacts the top of the two I-shaped limiting plates 106, the button stops descending. The limiting spring 108, under its elastic force, supports the inner wall of the irregularly shaped clamping plate 107, ensuring the button does not slip. As the rectangular contact plate 105 descends with the button, it will drive the connecting... When the connecting plate 2 moves, it will drive the hollow strip block 110 to move. The hollow strip block 110 will drive the sliding block 202 to move towards the inner wall of the button. The sliding block 202 will drive the rubber block 203 to contact the inner wall of the button. Since the hollow strip block 110 is equipped with a return spring 201, the return spring 201 will undergo compression deformation when the rubber block 203 contacts the inner wall of the button. The elastic force of the return spring 201 will improve the stability of the rubber block 203 on the button. Since the rubber block 203 is made of rubber, it will increase the friction with the inner wall of the button. The friction will ensure that the button is more stable on the device.

[0032] After painting, manually adjust the irregularly shaped transmission rod 206 upwards. The irregularly shaped transmission rod 206 will drive the connecting rectangular plate 205 to rise, which in turn will drive several rectangular contact plates 105 to rise. The rectangular contact plates 105 will then drive the connecting plate 2 to move, causing the rubber block 203 to release its support from the button. As the rectangular contact plates 105 continue to rise, they will push the button out of the irregularly shaped clamping plate 107, allowing the button to be quickly demolded. The correspondingly earlier release of the rubber block 203 from the button effectively avoids wear caused by the rubber block 203 when it leaves the button, thereby protecting the friction characteristics of the rubber block 203 and extending its service life.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
