[0025] 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.

[0026] As mentioned in the background art, in the prior art, it is difficult to properly insulate the preheated aluminum bar during extrusion, resulting in excessive cooling of the portion of the aluminum bar that has not yet entered the extrusion die, which reduces fluidity and increases the difficulty of extrusion. The present utility model provides an extrusion die for a square tubular aluminum profile. Example

[0027] Reference Figures 1 to 2 A square tubular aluminum profile extrusion die comprises a base 1 on which a hydraulic extrusion assembly 2, a square tube extrusion die assembly 3 and a hot air blower 8 are arranged;

[0028] A fixed pipe 4 is provided on the right side of the hydraulic extrusion assembly 2, and a connecting pipe 5 is provided on the left end of the square tube extrusion die assembly 3;

[0029] The opposite sides of the fixed pipe 4 and the connecting pipe 5 are in contact with the semicircular insulation board 6;

[0030] A bidirectional electric guide rail 7 is provided on the base 1, and the two sides of the bidirectional electric guide rail 7 are respectively connected to the two semicircular insulation plates 6. The left end of the aluminum rod is connected to the hydraulic extrusion assembly 2. The telescopic end of the hydraulic extrusion assembly 2 extends from the fixed tube 4 to push the aluminum rod to move, so that it passes through the connecting tube 5 and enters the square tube extrusion die assembly 3 to extrude a square tubular aluminum profile. After the aluminum rod is placed, the bidirectional electric guide rail 7 drives the two semicircular insulation plates 6 to move between the opposite sides of the fixed tube 4 and the connecting tube 5 until the two stop when they contact each other.

[0031] The hot air blower 8 is connected to the telescopic hose 9, the telescopic hose 9 is connected to the connection box 10, the connection box 10 is evenly connected with the air supply pipe 11, and the air supply pipe 11 is connected to the bottom semicircular insulation board 6;

[0032] The top semicircular insulation board 6 is evenly connected with an exhaust pipe 12, and valves are provided on the air supply pipe 11 and the exhaust pipe 12. The hot air blower 8 sends hot air into the connection box 10 through the telescopic hose 9, so that the air supply pipe 11 sends hot air between the two semicircular insulation boards 6, so that the original cold air is heated, and the exhaust pipe 12 is used to discharge excess air;

[0033] Even if the valve is closed, the air supply pipe 11 and the exhaust pipe 12 will still lose temperature due to the lack of insulation material covering the semicircular insulation plate 6. Therefore, arc-shaped insulation rods 13 are fitted and connected to the inner walls of the semicircular insulation plates 6 on both sides, and the arc-shaped insulation rods 13 are connected to the moving component; the top arc-shaped insulation rod 13 is located directly below the exhaust pipe 12, and the bottom arc-shaped insulation rod 13 is located directly above the air supply pipe 11.

[0034] The moving component includes an arc-shaped tooth plate 14 connected to both ends of the arc-shaped insulation rod 13. The arc-shaped tooth plate 14 is slidably mounted on the guide plate 15. The guide plate 15 is connected to the semicircular insulation plate 6. The arc-shaped tooth plate 14 is meshed with a gear 18. The gear 18 is set on the rotating shaft 17, and the right end of the rotating shaft 17 is connected to the semicircular insulation plate 6 through a bearing. In order to make the rotating shaft 17 rotate, a motor 16 is provided on the semicircular insulation plate 6, and the output shaft of the motor 16 is connected to the rotating shaft 17. The motor 16 is controlled and powered by existing technology, so that the rotating shaft 17 rotates, which can rotate the gear 18, and then the arc-shaped tooth plate 14 moves on the guide plate 15, which can move the arc-shaped insulation rod 13 without affecting the air inlet and outlet. After the heating is completed, it can also block the air supply pipe 11 and the exhaust pipe 12 to achieve insulation there.

[0035] An arc-shaped sliding groove matching the guide plate 15 is provided in the arc-shaped tooth plate 14 so that the arc-shaped tooth plate 14 can slide along the circumference.

[0036] The two motors 16 are both located outside the connecting pipe 5 , which does not affect the movement of the motors 16 following the semicircular insulation plate 6 .

[0037] The left end of the rotating shaft 17 is connected to the semicircular insulation plate 6 through a bearing to improve the stability during rotation. Example

[0038] Reference Figure 1 The air inlet of the hot air blower 8 is provided with a filter to avoid sending in hot air with dust and impurities.

[0039] The rest of the structure is the same as that of Example 1.

[0040] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
