[0003] The above-mentioned patents have the following shortcomings:

[0004] When the aluminum column is forced through the through hole of the upper mold, the solid aluminum column needs a lot of kinetic energy to pass through the through hole, which results in a large energy consumption during the extrusion molding process of the aluminum column through the mold. Utility Model Content

[0005] In view of the problems existing in the current microchannel aluminum flat tube extrusion molding die, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a microchannel aluminum flat tube extrusion molding die, which solves the problem that when the aluminum column passes through the through hole of the upper die, the solid aluminum column has to be forced through the through hole, which requires a lot of kinetic energy to pass through, resulting in high energy consumption during the extrusion molding process of the aluminum column through the die.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A microchannel aluminum flat tube extrusion molding die includes an upper die and a lower die that cooperates with the upper die to complete the extrusion molding of the aluminum flat tube. The upper die has a first through hole and an integral cutting component, which is located on the outer side of one end of the first through hole.

[0009] As a preferred embodiment of the microchannel aluminum flat tube extrusion molding die of this utility model, the upper die is provided with a second through hole, and an upper die core is inserted into the second through hole. The upper die core is fixed to the upper die by bolts.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0024] This utility model provides a microchannel aluminum flat tube extrusion molding die. Please refer to [link / reference]. Figure 1-3 The device includes an upper mold 1 and a lower mold 7 that cooperates with the upper mold 1 to complete the extrusion forming of aluminum flat tubes. The upper mold 1 has a first through hole 3 and an integral cutting component, which is a cutting ring 5. Before the aluminum column passes through the first through hole 3, the aluminum column first contacts the cutting ring 5 and is cut by the cutting ring 5. Compared with the aluminum column directly passing through the first through hole 3 on the upper mold 1, it is easier for the aluminum column to pass through the cutting ring 5, thereby reducing the power required to drive the aluminum column to move, thus saving energy. The cutting component is located on the outer side of one end of the first through hole 3.

[0025] The upper mold 1 has a second through hole 13, and an upper mold core 2 is inserted into the second through hole 13. The upper mold 1 has a second internal thread hole 15, and the upper mold core 2 has an internal thread hole that corresponds to and matches the second internal thread hole 15. The upper mold core 2 is fixed to the upper mold 1 by bolts.

[0026] The lower mold 7 has a lower mold core 9 inserted inside it. The lower mold core 9 has an aluminum flat tube passing through a through hole 12. The lower mold 7 and the lower mold core 9 are fixed together by bolts.

[0027] The lower mold 7 has an embedding notch 8 on its inner wall, and the lower mold core 9 has an integrally formed embedding block 10 on its outer wall. The embedding block 10 is embedded in the embedding notch 8, and the embedding block 10 has a first internal thread hole 11. The lower mold 7 has an internal thread hole that corresponds to and matches the first internal thread hole 11. The embedding block 10 and the lower mold 7 are fixed together by bolts.

[0028] The lower mold 7 is welded with a guide post 6, and the upper mold 1 is provided with a guide through hole 4. The guide post 6 passes through the through hole 4, and a nut is threaded onto the guide post 6. Tightening the nut will press the upper mold 1 together, thereby realizing the installation between the upper mold 1 and the lower mold 7.

[0029] In practical use, the upper mold core 2 is inserted into the second through hole 13 of the upper mold 1, and the upper mold core 2 and the upper mold 1 are fixed together with bolts; the lower mold core 9 is inserted into the lower mold 7, and the insert block 10 is inserted into the insert notch 8. The insert block 10 and the insert notch 8 are connected by an interference fit, and the insert block 10 and the lower mold 7 are fixed together with bolts; the guide post 6 is passed through the guide through hole 4, and a nut is threaded onto the guide post 6. The nut is tightened to press the upper mold 1, thus realizing the installation between the upper mold 1 and the lower mold 7; before the aluminum post passes through the first through hole 3, the aluminum post first contacts the cutting ring 5 and is cut by the cutting ring 5. After that, the aluminum post can pass through the first through hole 3 with less effort, thus saving more energy. Example 2

[0030] See attached document Figure 4-5 Unlike Embodiment 1, the cutting element is configured as a plurality of cutting blades 14. Similarly, before the aluminum column passes through the first through hole 3, the aluminum column passes through a plurality of cutting blades 14, thereby cutting out multiple holes on the aluminum column, making it easier for the aluminum column to pass through the first through hole 3.

[0031] In practical use, the upper mold core 2 is inserted into the second through hole 13 of the upper mold 1, and the upper mold core 2 and the upper mold 1 are fixed together with bolts; the lower mold core 9 is inserted into the lower mold 7, and the insert block 10 is inserted into the insert notch 8, and the insert block 10 is fixed together with the lower mold 7 with bolts; the guide post 6 is passed through the guide through hole 4, and a nut is threaded onto the guide post 6. The nut is tightened to press the upper mold 1, thus realizing the installation between the upper mold 1 and the lower mold 7; before the aluminum column passes through the first through hole 3, the aluminum column passes through several cutting blades 14, thereby cutting multiple holes on the aluminum column, making it easier for the aluminum column to pass through the first through hole 3, thus saving more energy.

[0032] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
