[0023] In the initial state, the movable end of the cylinder push rod 3 is retracted, the upper mold 4 is away from the lower mold 2, the upper heat conduction plate 5 is away from the lower heat conduction plate 7, and the upper ring plate 6 is away from the lower ring plate 8.

[0024] In summary, in use, the upper mold 4 and the lower mold 2 are cooled by air cooling, the cooling speed is accelerated, the cooling time is shortened, and the working efficiency is improved, so it is more practical.

[0025] As shown in Figure 2 some embodiments, the communication between the air inlet cylinder 10 and the lower heat dissipation cavity is configured in a outwardly expanding cone shape.

[0026] Referring to the above, when the external air enters the lower heat dissipation cavity from the air inlet cylinder 10, the outwardly expanding cone shape can make the external air more evenly divided.

[0027] As shown in Figure 5 some embodiments, a plurality of grooves 12 are configured on the heat dissipation fin 9, and the grooves 12 are distributed along the length direction of the heat dissipation fin 9.

[0028] Referring to the above, when the external air passes through the heat dissipation channel, the plurality of grooves 12 can increase the contact area between the external air and the heat dissipation fin 9, thereby improving the heat dissipation efficiency and cooling effect.

[0029] As shown in Figures 3-5As shown in the drawings, in some embodiments, the upper heat-conducting plate 5 and the lower heat-conducting plate 7 are both internally provided with accommodating cavities, the accommodating cavities are annular, and the accommodating cavities are filled with heat-conducting silicone grease 13. The heat-conducting silicone grease 13 is a heat-conducting organic silicone compound prepared by using organic silicone as a main raw material and adding materials with excellent heat resistance and heat conductivity. The heat-conducting silicone grease 13 is a high-heat-conducting and insulating organic silicone material with excellent heat conductivity.

[0030] As described above, in use, the heat-conducting efficiency of the upper heat-conducting plate 5 and the lower heat-conducting plate 7 can be improved by the cooperation of the accommodating cavities and the heat-conducting silicone grease 13, so as to further improve the cooling effect.

[0031] As shown in the drawings, Figures 3-5 In some embodiments, the lower heat-conducting plate 7 and the lower annular plate 8 are both provided with sealing grooves 14, the sealing grooves 14 are annular, and the upper heat-conducting plate 5 and the upper annular plate 6 are both provided with sealing rings 15 which are inserted into the sealing grooves 14.

[0032] As described above, when the upper heat-conducting plate 5 and the lower heat-conducting plate 7 are abutted and overlapped, and the upper annular plate 6 and the lower annular plate 8 are abutted and overlapped, the two sealing rings 15 are correspondingly inserted into the two sealing grooves 14, respectively, so as to form a sealing structure and improve the sealing property. Conversely, when the upper heat-conducting plate 5 is away from the lower heat-conducting plate 7, and the upper annular plate 6 is away from the lower annular plate 8, the two sealing rings 15 are withdrawn from the two sealing grooves 14, respectively.

[0033] As shown in the drawings, Figures 2-6 In some embodiments, the air inlet of the air inlet cylinder 10 is detachably provided with a first filter screen 16 which is in a vertical direction, and the air outlet of the upper heat-dissipating cavity is detachably provided with a second filter screen 17 which is in a horizontal direction.

[0034] As described above, in use, the first filter screen 16 is installed at the air inlet of the air inlet cylinder 10, and the second filter screen 17 is installed at the air outlet of the upper heat-dissipating cavity. When external air enters the air inlet cylinder 10, dust and impurities are filtered by the first filter screen 16, so as to avoid the dust and impurities from adhering to the upper heat-conducting plate 5, the lower heat-conducting plate 7 and the heat-dissipating fins 9, thereby avoiding affecting the heat-dissipating effect. The setting of the second filter screen 17 can avoid the dust and impurities from falling into the upper heat-dissipating cavity, thereby avoiding the dust from adhering to the upper heat-conducting plate 5, the lower heat-conducting plate 7 and the heat-dissipating fins 9, so as to avoid affecting the heat-dissipating effect. Meanwhile, the external air can backflush the second filter screen 17, so as to clean the second filter screen 17. The first filter screen 16 and the second filter screen 17 can be detached, so as to facilitate cleaning.

[0035] As shown in the drawings, Figure 6As shown, in some embodiments, the first filter screen 16 is constructed in a stepped shape and is inserted into the air inlet duct 10. A locking block 18 is provided on the first filter screen 16. The locking block 18 is horizontal and fixed on the first filter screen 16. A locking rod 19 is hinged to the air inlet duct 10. A notch 20 is constructed on the locking rod 19. The locking rod 19 and the notch 20 are inserted into each other.

[0036] Referring to the above, when the first filter screen 16 is installed at the air inlet of the air inlet duct 10, the first filter screen 16 is inserted and engaged with the air inlet duct 10, the locking rod 19 is in a horizontal direction, and the locking block 18 is located in the notch 20, so the first filter screen 16 cannot move. Conversely, when it is necessary to remove the first filter screen 16, the locking rod 19 is rotated upward, the locking block 18 is disengaged from the notch 20, and the first filter screen 16 can be moved away from the air inlet duct 10.

[0037] like Figure 4 As shown, in some embodiments, the second filter screen 17 is constructed in a stepped shape and is inserted into the upper heat dissipation cavity. The second filter screen 17 abuts and overlaps with the upper heat conduction plate 5 and the upper ring plate 6. A fixing block 21 is provided on the second filter screen 17. The fixing block 21 is fixed on the second filter screen 17. A positioning groove 22 is constructed on the fixing block 21. The positioning groove 22 is U-shaped. A screw 23 is hinged on the upper ring plate 6 and is inserted into the positioning groove 22. A locking nut 24 is threaded on the screw 23 and abuts and overlaps with the fixing block 21.

[0038] Referring to the above, when the second filter 17 is installed at the air outlet of the upper heat dissipation cavity, the screw 23 is vertical and located in the positioning groove 22, the locking nut 24 is tightened and abuts against the fixing block 21, and the second filter 17 cannot move. Conversely, when it is necessary to disassemble the second filter 17, the locking nut 24 is loosened to move away from the fixing block 21, so that the screw 23 rotates out of the positioning groove 22, and the second filter 17 moves away from the upper heat dissipation cavity.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
