[0026] 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.

[0027] As mentioned in the background art, in order to solve the problem that it is inconvenient to keep the preheated aluminum rod warm in the prior art, the present invention provides an aluminum profile extrusion die. Example

[0028] Reference Figures 1 to 3 , an aluminum profile extrusion die, comprising a base 1, on which a hydraulic pushing component 2 and an extrusion die component 3 are provided;

[0029] A connecting pipe 4 is provided on the right side of the hydraulic pushing assembly 2, and a fixing pipe 5 is provided on the left side of the extrusion die assembly 3;

[0030] Two semicircular insulation plates 6 of the same structure are attached to opposite sides of the connecting pipe 4 and the fixing pipe 5, and the opposite sides of the two insulation plates 6 are in contact with each other;

[0031] A bidirectional electric guide rail 7 is provided on the base 1. The two sides of the output end of the bidirectional electric guide rail 7 are respectively connected to the two insulation plates 6, so that the two insulation plates 6 can move toward the side away from each other or toward the opposite side, thereby connecting the left end of the aluminum rod to the hydraulic pushing assembly 2, and then closing the two insulation plates 6, so that the aluminum rod can be moved to the right through the fixed pipe 5 and enter the extrusion die assembly 3 for extrusion. During the process of the aluminum rod moving to the right and being extruded, it is located between the two insulation plates 6, which can keep the aluminum rod warm.

[0032] It was found through use that since the aluminum rod does not fit the insulation board 6, after the aluminum rod is placed, the air between the two insulation boards 6 is cold air, which also cools the aluminum rod;

[0033] Therefore, a hot air blower 8 is provided on the base 1, and the air supply port of the hot air blower 8 is connected to an air supply pipe 10, and the air supply pipe 10 is connected to a telescopic hose 11, and the telescopic hose 11 is connected to a connecting box 12, and ventilation pipes 13 are evenly connected to the insulation plates 6 on both sides of the top and bottom; the bottom ventilation pipes 13 are connected to the connecting box 12; valves are provided on the ventilation pipes 13, and an air inlet net 9 is provided on the air inlet of the hot air blower 8. The valves on the upper and lower ventilation pipes 13 are opened, and then the hot air blower 8 is operated to draw air from the outside that is filtered through the air inlet net 9 for heating. After heating, the hot air is sent between the two insulation plates 6 through the air supply pipe 10, the telescopic hose 11 and the connecting box 12 through the bottom ventilation pipe 13, so that the cold air between the two insulation plates 6 is heated to prevent the cold air between the two insulation plates 6 from cooling the aluminum rod. After the heating is completed, the hot air blower 8 and the valves on the upper and lower ventilation pipes 13 are closed.

[0034] As the air intake net 9 is used, the surface of the air intake net 9 will be covered with dust. Therefore, a mounting rod 14 is provided on the hot air blower 8. The mounting rod 14 is connected to a rotating shaft 15 through a bearing. A brush 18 is installed on the rotating shaft 15. A gear 16 is provided on the rotating shaft 15, and the gear 16 is located on the front side of the brush 18. The gear 16 is meshed with a gear rod 17 connected to the connecting box 12. The rear end of the brush 18 is in contact with the air intake net 9. When the insulation board 6 is raised or lowered, the connecting box 12 moves accordingly, so that the gear rod 17 drives the gear 16 to rotate, and the rotating shaft 15 drives the brush 18 to clean the dust on the surface of the air intake net 9. Example

[0035] Reference Figures 2 to 3 The brush 18 passes through the rotating shaft 15 transversely, and a bolt 19 connected to the brush 18 is provided on the rotating shaft 15, so that the brush 18 is easy to replace after being worn.

[0036] The rest of the structure is the same as that of Example 1.

[0037] 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.
