[0028] The transmission assembly 2 includes: left and right screw rods 21, the outer parts of the left and right screw rods 21 are connected to the hole wall of the second circular through hole 112 through bearings, and two groups of rotating seats 22 are arranged on the outer parts of a group of left and right screw rods 21, and the inner rings of the rotating seats 22 are threadedly connected to the outer parts of the left and right screw rods 21. One end of the left and right screw rods 21 is fixedly inserted into the inner part of the gear 1 23, the outer part of the gear 1 23 is meshed with the outer part of the gear 2 24, and the inner part of the gear 2 24 is fixedly connected to the output shaft of the driving motor 25.

[0029] Furthermore, the driving motor 25 drives the left and right screw rods 21 on both sides to rotate counterclockwise through gear 2 24 and gear 1 23. When the left and right screw rods 21 rotate counterclockwise, they drive the two sets of rotating seats 22 outside them to move away from each other, and the two sets of rotating seats 22 drive the two sets of mold bodies 14 to move away from each other.

[0030] Furthermore, the driving motor 25 drives the left and right screw rods 21 on both sides to rotate clockwise through gear 2 24 and gear 1 23. When the left and right screw rods 21 rotate clockwise, they will drive the two sets of rotating seats 22 outside them to move closer to each other, and the two sets of rotating seats 22 will drive the two sets of mold bodies 14 to move closer to each other.

[0031] The demoulding assembly 1 includes a sliding rod 12, one end of which is inserted into the inside of the support plate 11, and the other end of the sliding rod 12 is inserted into the inside of the mold body 14. The inner wall of the mold body 14 is slidably connected to the outside of the sliding plate 17, one side of the sliding plate 17 is fixedly connected to one end of the sliding rod 12, and the outside of the sliding rod 12 is fixedly connected to the inner ring of the limit ring 13. The outside of the sliding rod 12 is slidably inserted into the inner ring of the spring 15, and the two ends of the spring 15 are supported between the limit ring 13 and the mold body 14.

[0032] The side of the support plate 11 is provided with a circular through hole 111 and a circular through hole 2 112, and there are two groups of circular through holes 111 and 112, and the hole walls of the two groups of circular through holes 111 are slidably sleeved on the outside of the sliding rod 12. A circular through hole 3 141 is provided on one side of the mold body 14, and there are two groups of circular through holes 3 141, and the hole walls of the two groups of circular through holes 3 141 are slidably sleeved on the outside of the sliding rod 12. The top of the mold body 14 is provided with an injection hole 16 for injection.

[0033] Furthermore, the two groups of rotating seats 22 drive the two groups of mold bodies 14 away from each other, so that the mold body 14 moves toward the support plate 11. At this time, the formed laptop computer cover may adhere to one of the groups of mold bodies 14. When the mold body 14 moves toward the support plate 11, the limit ring 13 is pushed to move toward the support plate 11 by the spring 15. The limit ring 13 drives the sliding plate 17 to move toward the support plate 11 through the sliding rod 12. When the limit ring 13 moves to contact with the support plate 11, the support plate 11 will block the limit ring 13 from continuing to move, and then the sliding rod 12 will not be able to continue to slide, and the sliding plate 17 will not be able to continue to move toward the support plate 11. After the sliding plate 17 cannot move, it will block the formed laptop computer cover from continuing to move toward the support plate 11, and the mold body 14 continues to move toward the support plate 11 under the drive of the rotating seat 22, thus realizing the relative sliding of the laptop computer cover and the mold body 14, and then realizing the separation of the laptop computer cover and the mold body 14, so as to facilitate the removal of the laptop computer cover.

[0034] The air cooling assembly 3 includes: an outer frame 31, the top of the outer frame 31 is fixedly connected to the outside of the driving motor 25, and the inner wall of the outer frame 31 is provided with a filter screen 32 and a fan 34. The air cooling assembly 3 includes: threaded through holes 33 are opened on both sides of the outer frame 31, and the hole wall of the threaded through hole 33 is threadedly connected to the outside of the positioning screw 36, one end of the positioning screw 36 is movably inserted into the hole 35, and the hole 35 is provided on both sides of the filter screen 32.

[0035] Furthermore, the fan 34 is started, and the fan 34 blows air to the upper cover of the laptop computer for cooling, and the filter plate 32 filters the dust and impurities in the wind to prevent them from being attached to the laptop computer.

[0036] The bottoms of the outer frame 31 and the support plate 11 are both fixedly connected to the top of the base 4 , and the top of the base 4 is fixedly connected to the bottom of the flexible protection pad 5 .

[0037] Furthermore, after the upper cover of the laptop computer is separated from the mold body 14, it will fall onto the flexible protection pad 5. The flexible protection pad 5 is made of a soft material and can protect the upper cover of the laptop computer from being damaged.

[0038] Working principle: When in use, first start the drive motor 25, and the drive motor 25 drives the left and right screw rods 21 on both sides to rotate clockwise through gear 2 24 and gear 1 23. When the left and right screw rods 21 rotate clockwise, they will drive the two sets of rotating seats 22 outside them to move closer to each other, and the two sets of rotating seats 22 will drive the two sets of mold bodies 14 to move closer to each other. After the two sets of mold bodies 14 move closer to each other, the raw materials are injected into the two sets of mold bodies 14 from the injection holes 16. After the raw materials are solidified and formed, the drive motor 25 drives the left and right screw rods 21 on both sides to rotate counterclockwise through gear 2 24 and gear 1 23. When the left and right screw rods 21 rotate counterclockwise, they will drive the two sets of rotating seats 22 outside them to move away from each other, and the two sets of rotating seats 22 will drive the two sets of mold bodies 14 to move away from each other, so that the mold body 14 moves toward the support plate 11. At this time, the formed laptop cover may stick. It is connected to one group of mold bodies 14. When the mold body 14 moves toward the support plate 11, the spring 15 pushes the limit ring 13 to move toward the support plate 11. The limit ring 13 drives the sliding plate 17 to move toward the support plate 11 through the sliding rod 12. When the limit ring 13 moves to contact with the support plate 11, the support plate 11 will block the limit ring 13 from continuing to move, and then the sliding rod 12 will not be able to continue to slide, and the sliding plate 17 will not be able to continue to move toward the support plate 11. After the sliding plate 17 cannot move, it will block the formed laptop computer cover from continuing to move toward the support plate 11, and the mold body 14 continues to move toward the support plate 11 under the drive of the rotating seat 22, so that the relative sliding of the laptop computer cover and the mold body 14 is realized, and then the laptop computer cover and the mold body 14 are separated, so as to facilitate the removal of the laptop computer cover.
