[0025] Specifically, the mold body 2 is placed on the placement groove opened on the placement table 5, the bottom of the mold body 2 contacts the top of the placement plate 24, the clamping plate 25 limits the placement plate 24, and the turntable 10 is driven to rotate by the motor 11. The rotation of the turntable 10 drives the second fixed column 9 to rotate. The rotation of the second fixed column 9 drives the first fixed column 7 and the first mounting plate 6 to move through the connecting rod 8. When the first mounting plate 6 moves, it drives the placement table 5 to reciprocate through the cooperation of the crank 3. The reciprocating motion of the placement table 5 realizes the shaking of the mold body 2, which is convenient for helping to eliminate bubbles generated during the extrusion process when the mold body 2 is extruded to prevent affecting the product quality.

[0026] Reference Figure 1 and Figure 2 The lifting mechanism includes a second mounting plate 14, the outer wall of the second mounting plate 14 is fixedly connected to the leg of the frame 1, the top of the second mounting plate 14 is fixedly connected to an electric push rod 15, the output end of the electric push rod 15 is fixedly connected to a rack 23, the teeth of the rack 23 are meshed with a second gear 22, the middle part of the second gear 22 is fixedly connected to a rotating column 20, both ends of the rotating column 20 are rotatably connected to a vertical plate 18, the bottom of the vertical plate 18 is fixedly connected to the top of the second mounting plate 14, both ends of the rotating column 20 are fixedly connected to a first gear 19, the teeth of the first gear 19 are meshed with a gear column 17, a limit plate 16 is provided on one side of the gear column 17, the bottom of the limit plate 16 is fixedly connected to the top of the second mounting plate 14, the top of the gear column 17 is fixedly connected to the bottom of the placement plate 24, and the outer wall of the rack 23 is slidably connected to a sliding groove.

[0027] Specifically, the electric push rod 15 pushes the rack 23 to move, and the movement of the rack 23 causes the second gear 22 to rotate. The rotation of the second gear 22 drives the first gear 19 to rotate through the rotating column 20, and the rotation of the first gear 19 drives the gear column 17 to move up and down. The gear column 17 is located below the placement plate 24. When the gear column 17 rises, it pushes the placement plate 24 to rise. The rise of the placement plate 24 realizes the pushing out of the mold body 2 from the placement groove opened on the placement table 5, which is convenient for the staff to take out the formed TV frame.

[0028] Reference Figure 1 The fixing assembly includes a fixing frame 13 , one end of the fixing frame 13 is fixedly connected to one side of the frame 1 , the inner wall of the fixing frame 13 is fixedly connected to a fixing plate 12 , and the bottom of the motor 11 is fixedly connected to the top of the fixing plate 12 .

[0029] Specifically, the fixing plate 12 is convenient for fixing the motor 11, so that the motor 11 remains stable during operation, preventing the motor 11 from shaking, thereby improving the working efficiency of the entire device.

[0030] Reference Figure 2 A sliding plate 21 is fixedly connected to the bottom of the tooth column 17 , and one side of the sliding plate 21 is slidably connected to one side of the limiting plate 16 .

[0031] Specifically, the sliding plate 21 slides on the limiting plate 16 to move the tooth column 17, thereby preventing the tooth column 17 from deviating during the movement.

[0032] Reference Figure 1 and Figure 3 The side wall of the placement plate 24 is slidably connected to the inner wall of the placement groove opened on the placement platform 5.

[0033] Specifically, the placing plate 24 and the inner wall of the placing groove formed on the placing platform 5 are slidably connected to make the placing plate 24 more stable when it is raised.

[0034] Working principle: First, the staff places the mold body 2 on the top of the placement plate 24 and starts the motor 11. The motor 11 drives the turntable 10 to rotate, and further drives the second fixed column 9 to rotate. When the second fixed column 9 rotates, it drives the first fixed column 7 to move through the connecting rod 8. When the first fixed column 7 moves, it drives the first mounting plate 6 to move, and drives the placement table 5 to shake through the cooperation of the mounting column 4 and the crank 3. The shaking of the placement table 5 realizes the shaking of the mold body 2, which helps to prevent the generation of bubbles during extrusion. When the mold is formed, the electric push rod 15 is started to push the rack 23 to move, so as to realize the rotation of the second gear 22, and further drive the first gear 19 to rotate, so as to realize the rise of the tooth column 17. The rise of the tooth column 17 will push the placement plate 24 to rise. The rise of the placement plate 24 drives the mold body 2 to rise, which is convenient for the staff to take the mold after forming.
