[0028] 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.

[0029] Please see Figure 1 - Figure 8A conductive foam molding fixture includes a support base 1, a worktable 2 and a limiting post 3 fixedly mounted on the top of the support base 1, a spring 4 on the outer wall of the limiting post 3, a square top plate 5 fixedly mounted on the top of the limiting post 3, an upper pressing body 6 slidably connected to the outer wall of the limiting post 3, a transmission component 7 on the top of the square top plate 5, a lower pressing component 8 on the inner wall of the support base 1, a rack 9 and a rack 10 fixedly mounted on the inner wall of the worktable 2, a square groove 11 on the outer wall of the worktable 2, and a cleaning component 12 on the inner wall of the worktable 2.

[0030] The cleaning assembly 12 includes a cylinder 121. The telescopic end of the cylinder 121 is provided with a second drive shaft 122. The outer wall of the second drive shaft 122 is fixedly sleeved with a cleaning roller 123 and a gear 125. The inner wall of the worktable 2 is slidably connected with a second slide plate 124. The inner wall of the second slide plate 124 is fixedly installed with a cylinder 126. The outer wall of the cylinder 126 is rotatably sleeved with a second gear 127.

[0031] In the above structure, by setting the cleaning component 12, the entire cleaning component 12 can reciprocate to clean the conductive foam residue on the inner wall of the square groove 11.

[0032] In a preferred embodiment: the transmission component 7 includes an air pump 701, one end of an air pipe 702 is fixedly connected to the outer wall of the air pump 701, the other end of the air pipe 702 is fixedly connected to a square sealing box 703, and a solenoid valve 704 is fixedly connected to the outer wall of the square sealing box 703.

[0033] In a preferred embodiment: the bottom opening shape of the solenoid valve 704 is smaller than the top shape of the upper pressure body 6, and the inner wall of the solenoid valve 704 is slidably disposed with respect to the outer wall of the upper pressure body 6.

[0034] In the above structure, by setting up the air pipe 702, the square sealing box 703 and the solenoid valve 704, by starting the air pump 701, the air pump 701 will transmit gas to the inner cavity of the square sealing box 703 through the air pipe 702. The gas in the inner cavity of the square sealing box 703 will push the top of the upper pressure body 6 to move along the inner wall of the square sealing box 703. As a result, the top of the upper pressure body 6 will move to the bottom opening of the square sealing box 703 when it moves.

[0035] In a preferred embodiment: the pressing component 8 includes a lower box slot 801, the inner wall of the lower box slot 801 is provided with a sliding groove 802, the outer wall of the support base 1 is fixedly installed with a motor 803, the outer edge of the power output shaft of the motor 803 is fixedly sleeved with a transmission shaft 804, the outer wall of the transmission shaft 804 is fixedly sleeved with a camshaft 805, the inner cavity of the transmission shaft 804 is provided with a sliding plate 806, and the top of the sliding plate 806 is respectively provided with a spring 807 and a pressing body 808;

[0036] In a preferred embodiment: there are three camshafts 805, and the three camshafts 805 are respectively arranged in parallel at the bottom of the slide plate 806. The outer wall shape of the slide plate 806 is the same as the inner wall shape of the slide groove 802, and the outer wall of the slide plate 806 and the inner wall of the slide groove 802 are slidably arranged. There are four springs 807, and the four drive shafts 804 are all arranged around the top of the slide plate 806. The shape of the pressing body 808 is the same as the shape of the square groove 11, and the shape of the pressing body 808 is adapted to the shape of the square groove 11.

[0037] In the above structure, the arrangement of the camshaft 805, slide plate 806, spring 807, and pressing body 808 allows the motor 803 to be activated. The outer edge of the output shaft of the motor 803 drives the transmission shaft 804 to rotate, which in turn drives the three parallel camshafts 805 to rotate. When the bottoms of the three camshafts 805 rotate to contact the bottom of the slide plate 806, the slide plate 806 drives the pressing body 808 to slide along the inner wall of the groove 802, thus pressing the pressing body... The body 808 extends to fit against the inner wall of the square groove 11, while the spring 807 is compressed, thereby pressing down the conductive foam on the top of the body 808. After the conductive foam is pressed, the bottom of the three camshafts 805 rotates to 180 degrees, allowing the top of the camshafts 805 to extend away from the inner wall of the square groove 11 through a connected operation. This causes the camshafts 805 to drive the conductive foam at the top to separate from the top of the limiting post 3, thereby ejecting the pressed conductive foam.

[0038] In a preferred embodiment: the outer edge of gear 2 127 has the same shape as the outer edge of rack 1 9, and the outer edge of gear 2 127 is meshed with the outer edge of rack 1 9;

[0039] In the above structure, by setting gear 2 127 and rack 1 9, the outer edge of gear 2 127 will mesh with the outer edge of rack 1 9 when rotating.

[0040] In a preferred embodiment: the outer edge of gear 125 has the same shape as the outer edge of rack 10, and the outer edge of gear 125 is meshed with the outer edge of rack 10;

[0041] In the above structure, the outer edge of gear 125 meshes with the outer edge of rack 10 when it rotates.

[0042] Working principle: When using this device, conductive foam is placed on top of the limiting post 3. Then, by starting the motor 803, the outer edge of the output shaft of the motor 803 drives the transmission shaft 804 to rotate. The rotating transmission shaft 804 drives three parallel camshafts 805 to rotate. When the bottom of the three camshafts 805 rotates to fit against the bottom of the sliding plate 806, the sliding plate 806 drives the pressing body 808 to slide along the inner wall of the groove 802. The pressing body 808 extends to fit against the inner wall of the square groove 11. At the same time, the spring 8... 07 will also be compressed, so that the top of the lower pressing body 808 will contact the bottom of the conductive foam. Then, by activating the air pump 701, the air pump 701 will transmit gas to the inner cavity of the square sealing box 703 through the air pipe 702. The gas in the inner cavity of the square sealing box 703 will push the top of the upper pressing body 6 to move along the inner wall of the square sealing box 703. As the upper pressing body 6 moves, the top will extend to the bottom opening of the square sealing box 703, so that the bottom of the upper pressing body 6 will contact the top of the conductive foam, thereby achieving the compression of the conductive foam.

[0043] After the equipment completes the pressing of the conductive foam, the gas in the inner cavity of the square sealing box 703 is depressurized by the solenoid valve 704, so that the upper pressing body 6 will be reset by the compression and rebound of the spring 4. At the same time, the bottom of the three camshafts 805 will rotate to 180 degrees, so that the top of the camshafts 805 can be extended to disengage from the inner wall of the square groove 11 through the operation. This will cause the camshafts 805 to drive the top of the conductive foam to disengage from the top of the limiting post 3, thereby ejecting the pressed conductive foam. Then, the camshafts 805 can be reset by the same operation.

[0044] By activating cylinder 121, the telescopic end of cylinder 121 drives slide plate 124 to slide along the inner wall of square groove 11. Slide plate 124 drives gear 127 to rotate along rack 9. Simultaneously, as slide plate 124 moves, it also drives the outer edge of drive shaft 122 to rotate along the outer edge of rack 10. As drive shaft 122 rotates, it drives the cleaning roller 123 on the outer edge to rotate. The cleaning roller 123 then cleans the residue on the top of the reset pressing body 808. The same operation can be used to reset and clean the cleaning roller 123, thus effectively ensuring the cleanliness of the top of the pressing body 808.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
