Problems solved by technology

However, in terms of complex core structure aluminum profile extrusion dies, due to the complex core structure of the mold, it is very inconvenient to design and process the mold, the design is difficult, the processing accuracy is poor, and the uniformity of the mold supply is not good, resulting in The stability of the mold core is not good, and it is easy to deflect or even break, causing uneven wall thickness of the aluminum profile, poor surface quality, poor molding or even scrapping

Embodiment Construction

[0029] see Figure 1~Figure 6 , the present invention is an aluminum profile extrusion die with a complex core structure, which is formed by superimposing an upper die and a lower die 3 front and back, and the upper die is composed of a first-level upper die 1 and a second-stage upper die 2, forming a In the disassembled structure, eight splitter bridges 4 are evenly arranged on the feeding surface of the first-level upper die 1, and eight first splitter holes 5 are formed between the eight splitter bridges 4, and the first-stage upper die 1 A boss 6 is arranged on the discharge surface, and the center of the boss 6 is provided with a first mold core 7. The feed surface of the secondary upper die 2 is set behind the first-stage upper die, and the second-stage upper die 2 There is a center hole 9 in the center of the center hole 9, and eight second diverter holes 10 are arranged on the periphery of the center hole 9. The center hole 9 is used to match the boss of the upper mold...

Abstract

The invention relates to an aluminum profile extrusion die with a complicated die core structure. The aluminum profile extrusion die is formed by overlaying an upper die and a lower die (3) front and back, wherein the upper die comprises a first-grade upper die (1) and a second-grade upper die (2); eight first shunting holes (5) are uniformly formed in the feeding surface of the first-grade upper die (1); a boss (6) is arranged on the discharging surface of the first-grade upper die (1); a first die core (7) is arranged at the center of the boss (6); a central hole (9) is formed in the center of the feeding surface of the second-grade upper die (2); eight second shunting holes (10) are formed in the periphery of the central hole (9); the discharging surface of the second-grade upper die (2) is provided with a second die core (11) around the central hole (9); and an inner shunting hole (12) is formed between the boss (6) and the central hole (9). The aluminum profile extrusion die with the complicated die core structure is convenient to machine, high in machining accuracy, good in material supply uniformity, and good in aluminum profile formability.

Description

technical field [0001] The invention relates to an aluminum profile extrusion die with complex core structure, belonging to the technical field of aluminum profile dies. Background technique [0002] Because aluminum has good extrusion formability, and has the advantages of light specific gravity and good strength, aluminum is widely used in technical fields such as industry and decoration. However, in terms of complex core structure aluminum profile extrusion dies, due to the complex core structure of the mold, it is very inconvenient to design and process the mold, the design is difficult, the processing accuracy is poor, and the uniformity of the mold supply is not good, resulting in The stability of the mold core is not good, and it is easy to deflect or even break, causing uneven wall thickness of the aluminum profile, poor surface quality, poor molding or even scrapping. Contents of the invention [0003] The purpose of the present invention is to overcome the abov...
