Electromagnetic absorbers, as a special material, play an important role in military and communications fields. However, during the 3D printing of electromagnetic absorbers, due to limitations in material properties and printing speed, the printed electromagnetic absorbers often have high temperatures. Failure to cool them down in time may lead to damage. Therefore, developing an efficient and rapid cooling mechanism is of great significance for improving the quality and efficiency of 3D printing electromagnetic absorbers. Utility Model Content

[0024] Cooling device, the cooling device includes an enclosing component, an air cooling component and a sealing component. The enclosing component is used to enclose the printing position, the air cooling component is used to air - cool the 3D printing position, and the sealing component is used to seal the periphery of the enclosing position to enhance the heat dissipation effect of the printing position;

[0025] Lifting device, the lifting device is used to drive the cooling device to lift.

[0026] The enclosing component includes a connecting pipe 2, symmetrically arranged X - direction enclosing plates 3 and symmetrically arranged Y - direction enclosing plates 4. The X - direction enclosing plates 3 and Y - direction enclosing plates 4 are used to install radiators 5. The symmetrically arranged X - direction enclosing plates 3 are connected to each other through the connecting pipe 2, and the symmetrically arranged Y - direction enclosing plates 4 are also connected to each other through the connecting pipe 2. The X - direction enclosing plates 3 and Y - direction enclosing plates 4 are arranged perpendicular to each other.

[0027] The air cooling component includes radiators 5. The radiators 5 are air - cooled radiators. The specific model of the air - cooled radiator 5 can be reasonably selected according to the 3D - printed parts. There are several radiators 5, and several radiators 5 are respectively arranged on the X - direction enclosing plates 3 and Y - direction enclosing plates 4. The connecting pipe 2 is provided with several air outlets, and the output ends of the radiators 5 and the air outlets are interconnected.

[0028] The closure assembly includes a snap-fit ​​block 6, rollers 7, mounting rods 8, torsion springs 9, sleeves 10, and sealing membranes 11. The snap-fit ​​block 6 has a cross-shaped structure and a hollow interior. In use, the snap-fit ​​block 6 is positioned at the connection between the X-direction enclosure plate 3 and the Y-direction enclosure plate 4. The snap-fit ​​block 6 is connected to rollers 7, which are located on different side walls of the snap-fit ​​block 6 and fit against either the X-direction enclosure plate 3 or the Y-direction enclosure plate 4. The rollers 7 ensure that the snap-fit ​​block 6 does not impede the movement of the X-direction enclosure plate 3 and the Y-direction enclosure plate 4. The mounting rod 8 is fixedly connected to the snap-fit ​​block. 6. Mounting rod 8 is used to mount torsion spring 9 and sleeve 10. Torsion spring 9 is sleeved on mounting rod 8, and both ends of torsion spring 9 are fixedly connected to mounting rod 8 and sleeve 10. Torsion spring 9 drives sleeve 10 to move, thereby keeping sealing membrane 11 taut. As shown in the attached diagram of the instruction manual, both ends of sealing membrane 11 are fixedly connected to sleeve 10 set on different snap-fit ​​blocks 6. The sealing membrane 11 set around the perimeter seals the area between X-direction enclosure plate 3 and Y-direction enclosure plate 4, thereby making heat dissipation management more concentrated and efficient.

[0029] The enclosure assembly also includes a drive push rod 12 and a connecting plate 13. The drive push rod 12 is a DC electric push rod. The drive push rod 12 is used to push the X-direction enclosure plate 3 or the Y-direction enclosure plate 4 on the same side to move closer or further apart. The drive push rod 12 is symmetrically arranged on the connecting plate 13. The X-direction enclosure plates 3 on the same side are connected to each other through the connecting plate 13.

[0030] The lifting device includes a lifting push rod 14, which is a DC electric push rod. The two ends of the lifting push rod 14 are connected to the printing cavity and the connecting plate 13, respectively. The lifting push rod 14 is used to drive the printing connecting plate 13 to be raised and lowered in real time according to the 3D printing data.

[0031] Working principle: When printing the electromagnetic absorber, the lifting push rod 14 will adjust the height of the connecting plate 13 in real time according to the 3D printing data. Then, according to the printing position, the drive push rod 12 will drive the X-direction enclosure plate 3 and the Y-direction enclosure plate 4 to enclose the printing position. At the same time, the heat sink 5 will be activated to blow air to the printing position through the connecting pipe 2 at close range, so as to achieve efficient heat dissipation.

[0032] When the X-direction enclosure plate 3 or the Y-direction enclosure plate 4 moves away from each other, the sealing film 11 will be pulled, the sleeve 10 will rotate, and the torsion spring 9 will be deformed by force. When the X-direction enclosure plate 3 or the Y-direction enclosure plate 4 moves closer to each other, the torsion spring 9 will reset, thereby driving the sleeve 10 to move, so that the sealing film 11 is re-stored on the sleeve 10.

[0033] 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.
