[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] As Figures 1 to 14 shown, the present invention provides a carbon fiber shell hot and cold pressing forming machine, including a hot pressing area 1 and a cold pressing area 2, and further including:

[0045] A channel 3, which is arranged in the middle area between the hot pressing area 1 and the cold pressing area 2 and is used to connect the hot pressing area 1 and the cold pressing area 2;

[0046] The moving module 6 is installed inside the channel 3;

[0047] The shaking part 7 is arranged on the inclined plane of the inner cavity of the channel 3;

[0048] The channel 3 includes a housing 31 whose two ends are respectively installed with the hot pressing area 1 and the cold pressing area 2. An air duct 33 is opened at the upper end of the inner cavity of the housing 31, and a number of first air outlet grooves 32 are equidistantly opened on both sides of the housing 31;

[0049] The moving module 6 includes a moving plate 61 installed in the inner cavity of the housing 31. The two ends of the moving plate 61 penetrate through the housing 31 and are abutted against the movable components 64 arranged on the housing 31. One side of the moving plate 61 is installed with a corrugated air outlet pipe 62; The movable component 64 includes a movable plate 641, and a first air cavity 643 communicated with the air duct 33 is opened inside the movable plate 641;

[0050] The shaking part 7 includes spheres 71 which are connected to the housing 31 by bearings, are arranged at equal intervals and have different sizes. Three air holes 72 with different orientations are opened in the inner cavity of the sphere 71, and the housing 31 is communicated with the inner cavity of the sphere 71 through a second air cavity 73.

[0051] As Figure 1 and Figure 2 shown, a supporting part 4 is movably connected to the inner cavity of the hot pressing area 1, and the supporting part 4 can convey the carbon fiber shell inside the hot pressing area 1 and the channel 3 through a hydraulic driving part 5.

[0052] As Figure 3 and Figure 4 shown, the supporting part 4 includes a supporting plate 41 placed below the hot pressing area of the hot pressing area 1 and a movable rod 44. There is a gap between the supporting plate 41 and the top surface at the lower end of the inner cavity of the hot pressing area 1;

[0053] An arc groove is opened inside the lower end of the supporting plate 41. A support seat 42 is hinged in the arc groove. L-shaped rods 43 are installed on both sides of the support seat 42. The movable rod 44 is arranged on both sides of the moving module 6 and is bearing-connected to the inner cavity of the housing 31.

[0054] Adopting the above solution: When the hydraulic driving member 5 pulls the supporting plate 41, the supporting seat 42 and the L-shaped rod 43 to move together and the L-shaped rod 43 contacts the movable rod 44, the higher end of the L-shaped rod 43 will gradually abut against the movable rod 44, making the movable rod 44 gradually become vertical. The top end of the movable rod 44 will gradually abut against the supporting plate 41 to cause it to slightly flip on the top surface of the supporting seat 42. Since the height of the supporting plate 41 is slightly higher than the top surface height of the inner cavities of the hot pressing area 1 and the cold pressing area 2, the carbon fiber outer shell and its mold located on the top of the supporting plate 41 will tilt, and then can slide down smoothly. In the initial situation, the bottom end of the movable rod 44 abuts against a baffle that restricts its movement, and the shift knob is installed on the housing 31. Therefore, the movable rod 44 is in an inclined state initially, but the inclined height does not affect the movement of the supporting plate 41 above it.

[0055] As Figure 3 shown, a mold for pressing the carbon fiber outer shell and the carbon fiber outer shell material placed inside the mold are placed on the top of the supporting plate 41.

[0056] As Figure 6 shown, both sides of the moving plate 61 located inside the housing 31 are elastically connected to the housing 31 through the first spring 63, and the contact end of the moving plate 61 with the movable plate 641 is provided with an oblique angle.

[0057] Adopting the above solution: The opening of the oblique angles at both ends of the moving plate 61 causes that when the moving plate 61 is gradually abutted by the supporting seat 42, its oblique angle end will gradually abut against the movable plate 641, making the two movable plates 641 move towards each other inside the housing 31.

[0058] As Figure 6 and Figure 9 shown, a transverse groove for the transverse movement of the movable plate 641 is opened in the inner cavity of the housing 31, and one end of the movable plate 641 is arranged in this transverse groove;

[0059] The movable plate 641 is elastically connected to the housing 31 through the second spring 642, and the top of the movable plate 641 is communicated with the air passage 33 through the first connecting pipe 644.

[0060] Adopting the above solution: The second spring 642 provides a subsequent stable limiting effect for the movable plate 641. At the same time, the gas inside the air passage 33 will enter the inside of the first air cavity 643 through the first connecting pipe 644 and be discharged downward from the first air cavity 643 to the movable plate 641.

[0061] As Figure 6 、 Figure 8 and Figure 9 shown, the opposite ends and the contact ends with the supporting member 4 of the two movable plates 641 are all in a bevel shape, and an oblique rectangular groove for exhausting the gas inside the first air cavity 643 is opened on the bottom surface of the movable plate 641;

[0062] The bottom surface of the movable plate 641 is exactly located on the top surface of the supporting plate 41.

[0063] Adopting the above scheme: The inclined surface setting of the end surface of the movable plate 641 enables that when the two movable plates 641 move towards each other, the inclined end will smoothly move along the middle gap between the bottom surface of the mold with a carbon fiber shell and the top surface of the supporting plate 41, thereby slightly lifting the mold with a carbon fiber shell above the supporting plate 41 upwards. The top surface of the mold with a carbon fiber shell and the supporting plate 41 will not be in contact. At the same time, through the connection between the first connecting pipe 644 and the first air chamber 643, part of the gas is blown from the bottom surface of the first air chamber 643 to the lower part of the mold.

[0064] As Figures 12 to 14 shown, the second air chamber 73 is connected to the corrugated pipe air outlet pipe 62. An impurity discharging groove is provided at one end of the housing 31 far away from the second air chamber 73, and four groups of staggered inclined plates 75 are arranged in the groove.

[0065] As Figure 13 shown, the second air chamber 73 is connected to the inclined plate 75 through the second connecting pipe 74. A second air outlet groove 76 is provided at one end of the inclined plate 75 far away from the second connecting pipe 74, and the second air outlet groove 76 is obliquely arranged opposite to the inclined surface of the inclined plate 75.

[0066] Adopting the above scheme: When the gas inside the corrugated pipe air outlet pipe 62 enters the second air chamber 73, the sphere 71 rotates on the housing 31 under the resistance of the air pressure. When one side of the air hole 72 is inside the second air chamber 73 and the other side is inside the inner cavity of the housing 31, the gas inside the second air chamber 73 will blow the bottom of the mold with a carbon fiber shell above the sphere 71 through the air hole 72. At the same time, the spheres 71 with different sizes will cause the mold with a carbon fiber shell to have a slight shaking phenomenon when sliding above the sphere 71. At the same time, the gas discharged downward from the second connecting pipe 74 through the inclined plate 75 and the second air outlet groove 76 will blow the inclined surface of the inclined plate 75, thereby accelerating the downward flow rate of the impurities in the impurity discharging groove. At the same time, the arrangement of multiple inclined plates 75 slows down the speed of the outside air flowing from this groove into the inside of the housing 31.

[0067] As Figure 2 and Figure 3 shown, a plurality of rubber air outlet pipes 8 are installed at the top of the inner cavity of the housing 31, and the rubber air outlet pipes 8 are connected to the air duct 33.

[0068] Adopting the above solution: The outer shape of the first air outlet groove 32 is "narrow outside and wide inside", which reduces the possibility of external impurities entering the inner cavity of the housing 31 through the first air outlet groove 32. When the inside of the rubber air outlet pipe 8 is filled with the gas in the air duct 33, the increase in air pressure will cause the lower end of the rubber air outlet pipe 8 to swing back and forth. At this time, the gas will also be discharged in a swinging manner, improving the flow velocity of the air flow.

[0069] The working principle and usage process of the present invention:

[0070] First, use the hydraulic device to open the blocking door on the hot pressing area 1, drive the hydraulic driving member 5 to drive the entire supporting member 4 to move into the inside of the channel 3. When the supporting seat 42 enters the inside of the housing 31, it will push the moving plate 61 to move synchronously. The inclined end of the moving plate 61 will gradually contact the movable plate 641, causing the two movable plates 641 to move towards each other inside the housing 31. The inclined surfaces of the two movable plates 641 will move from the middle gap between the bottom surface of the mold with the carbon fiber outer shell and the top surface of the supporting plate 41, so that the mold with the carbon fiber outer shell does not fit the top surface of the supporting plate 41;

[0071] Subsequently, the corrugated air outlet pipe 62 will be compressed synchronously, and the gas inside it will enter the inside of the first air chamber 643 through the air duct 33 and the first connecting pipe 644, and the gas will be discharged below the mold with the carbon fiber outer shell through the first air chamber 643, so as to improve the cooling effect on the mold with the carbon fiber outer shell;

[0072] At the same time, part of the gas inside the air duct 33 will enter the inside of the rubber air outlet pipe 8, and will blow back and forth in a swinging manner above the mold with the carbon fiber outer shell through the rubber air outlet pipe 8, so as to improve the flow effect of the internal air flow;

[0073] Finally, when the supporting seat 42 moves, the L-shaped rod 43 will contact the movable rod 44, making the movable rod 44 gradually become vertical, and its top will contact one side of the bottom surface of the supporting plate 41, causing the supporting plate 41 to be slightly turned over and applying a thrust to the mold with the carbon fiber outer shell, so that the mold with the carbon fiber outer shell can slide down through the inclined surface at one end of the inner cavity of the housing 31. During the sliding process, the second air chamber 73 is filled with the gas from the air duct 33, and the air pressure will push the sphere 71 to rotate. The spheres 71 of different sizes will slightly shake the sliding mold with the carbon fiber outer shell. At the same time, part of the gas will rotate through the spheres 71, and the air holes 72 will blow the mold with the carbon fiber outer shell on the top surface of the spheres 71;

[0074] When the mold with the carbon fiber outer shell slides into the inner cavity of the cold pressing area 2, the operator can adjust the position of the mold in the cold pressing area 2 through the hinged door on the outside, and then the subsequent cold pressing operation can be carried out.

[0075] It should be noted that the existing hot and cold pressing methods are adopted inside both the hot pressing area 1 and the cold pressing area 2, and hydraulic devices are provided at the connection ends of the hot pressing area 1 and the cold pressing area 2 with the channel 3. The hydraulic devices are used to drive the blocking door to move up and down to achieve the one-sided closing effect. At the same time, after the hot pressing is completed, the product is allowed to stand for a period of time before the operation of this equipment. It is not directly operated after the hot pressing is completed.

[0076] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0077] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
