[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a heat pipe forming device, including a base 1, the base 1 is connected to a mounting plate 3 through a four-column gantry frame 2, a high-tonnage pressure electric cylinder 7 is installed on the upper end of the mounting plate 3, and four sets of upper mold guide positioning sleeves 4 are provided on the lower end face of the mounting plate 3. A positioning slide rod 5 is inserted in the upper mold guide positioning sleeve 4, and the lower end of the positioning slide rod 5 is connected to the upper forming mold 6. The lower end of the high-tonnage pressure electric cylinder 7 is connected to the upper end face of the upper forming mold 6 through a telescopic arm. A transverse slide rail 12 is provided through the left and right sides of the base 1. A first multi-cavity forming lower mold 14 and a second multi-cavity forming lower mold 21 are respectively provided on the left and right sides of the transverse slide rail 12, and heat pipes 22 are placed on the first multi-cavity forming lower mold 14 and the second multi-cavity forming lower mold 21.

[0019] Furthermore, the upper forming mold 6 forms a lifting structure with the telescopic arm of the large-tonnage pressure electric cylinder 7 and the mounting plate 3.

[0020] In one embodiment, when the power supply of the large-tonnage pressure cylinder 7 is turned on, the large-tonnage pressure cylinder 7 is activated, and the telescopic arm is driven to descend by the large-tonnage pressure cylinder 7, thereby pressing down the upper forming mold 6 connected to the lower end of the telescopic arm. During the pressing process, the upper forming mold 6 is limited by the positioning slide rod 5 by four sets of upper mold guide positioning sleeves 4, thereby ensuring the downward trajectory of the upper forming mold 6.

[0021] The lower ends of the first multi-cavity molding lower mold 14 and the second multi-cavity molding lower mold 21 are both provided with transverse slides 13. The outer end of the transverse slide 13 is provided with a connecting plate 15, and the other end of the connecting plate 15 is provided with a pneumatic arm connector 16. A pneumatic arm 17 is connected inside the pneumatic arm connector 16. The other end of the pneumatic arm 17 on the left side is connected to the first transverse cylinder 18, and the other end of the pneumatic arm 17 on the right side is connected to the second transverse cylinder 20. The first transverse cylinder 18 and the second transverse cylinder 20 are both fixedly connected to the base 1 through the cylinder mounting seat 19.

[0022] Furthermore, multiple sets of recessed molding grooves are formed on the upper surfaces of both the first multi-cavity molding lower mold 14 and the second multi-cavity molding lower mold 21.

[0023] Furthermore, the first multi-cavity molding lower mold 14 and the second multi-cavity molding lower mold 21 respectively form a transverse moving structure on the transverse slide rail 12 through the first transverse cylinder 18 and the second transverse cylinder 20.

[0024] In one embodiment, when the heat pipe 22 needs to be pressed and formed, the blank to be pressed is placed on the first multi-cavity forming lower mold 14, and then the first transverse cylinder 18 drives the pneumatic arm 17 to move forward. The pneumatic arm 17 drives the first multi-cavity forming lower mold 14 to move towards the lower end of the forming upper mold 6 through the action of the pneumatic arm connector 16 and the connecting plate 15. Then, the forming upper mold 6 is pressed down by the high-tonnage pressure electric cylinder 7 to realize the pressing and forming operation of the heat pipe 22. During the pressing process of the first multi-cavity forming lower mold 14, the second multi-cavity forming lower mold 21 is fed. After the first multi-cavity forming lower mold 14 is pressed and formed and the material is unloaded, the second multi-cavity forming lower mold 21 can be switched to perform continuous pressing operation, thereby improving the production efficiency of the equipment.

[0025] The base 1 has a longitudinal slide rail 8 at the vertical front end of the transverse slide rail 12, and a longitudinal slide block 9 is installed on the longitudinal slide rail 8. A longitudinal cylinder 10 is installed on the longitudinal slide block 9, and the pneumatic arm 17 of the longitudinal cylinder 10 is connected to the top plate 11.

[0026] Furthermore, under the action of the longitudinal cylinder 10, the top plate 11 forms a front-to-back pushing structure with the longitudinal slide block 9 via the pneumatic arm 17.

[0027] In one embodiment, after the multi-cavity molding lower mold completes the pressing, the longitudinal cylinder 10 can be activated. The longitudinal cylinder 10 drives the pneumatic arm 17 to push the top plate 11 out, thereby ejecting the pressed heat pipe 22 from the multi-cavity molding lower mold and completing the pressing of the heat pipe 22. It should be noted that the longitudinal slide 9 on the longitudinal slide rail 8 is positioned by screws. After the position of the longitudinal slide 9 is fixed, the longitudinal cylinder 10 installed on the longitudinal slide 9 can drive the top plate 11 to perform the ejection operation. In addition, the stroke of the large-tonnage pressure electric cylinder 7, the first transverse cylinder 18, the second transverse cylinder 20 and the longitudinal cylinder 10 in this solution are parameters that have been set through experiments using existing technology. The technical content of the test process and parameters can be implemented by those skilled in the art and does not need to be described in detail here.

[0028] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
