Technical Field

[0001] The utility model relates to an aluminum profile extrusion die, in particular to a hollow aluminum profile extrusion die. Background Art

[0002] Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by melting and extruding aluminum bars. The production process of aluminum profiles mainly includes three steps: melting, extrusion, and coloring.

[0003] Aluminum profiles require an extrusion die during production. The heated raw material is squeezed into the extrusion die to form the extruded material into different shapes. The existing extrusion die consists of an upper die and a lower die. The lower die is provided with a feed port. The lower and upper dies are fixed to a die base and connected to each other via positioning columns. The upper surface of the lower die is provided with a special-shaped bump, while the upper surface of the upper die is provided with a special-shaped hole.

[0004] The heated raw material is squeezed into the space between the special-shaped convex block and the special-shaped hole, and then the extruded raw material is shaped into a hollow special-shaped material (i.e., a special-shaped hollow aluminum profile). In order to ensure sufficient strength, the existing upper mold only has a special-shaped hole (such as Figure 12 and Figure 13 As shown in the figure, a large part of the cylindrical block is unused, which not only causes material waste in actual use, but also makes the mold heavier as a whole, which puts a heavy burden on the staff during transportation and installation. When the mold is damaged, the replacement cost is also high. Therefore, a hollow aluminum profile extrusion mold is proposed to solve the above problems. Utility Model Content

[0038] Example 1

[0039] See also Figure 1 and Figure 2 , a hollow aluminum profile extrusion die, comprising:

[0040] Lower mold 1; and

[0041] A reinforcing cylinder 2 is provided at the top of the lower mold 1;

[0042] an upper mold member 4, which is disposed inside the reinforcement tube 2 and connected to the upper surface of the reinforcement tube 2;

[0043] The middle column 3 is disposed between the reinforcing tube 2 and the upper mold 4 and extends to the interior of the upper mold 4 .

[0044] Based on the above, the lower mold 1, the reinforcing cylinder 2, the upper mold 4 and the middle column 3 cooperate with each other to form a complete extrusion mold. At this time, the reinforcing cylinder 2, the upper mold 4 and the middle column 3 constitute the upper mold. Compared with the traditional upper mold, the upper mold has a smaller overall volume and lighter weight. The mold adopts a split setting. The lower mold 1 and the reinforcing cylinder 2 can be suitable for different upper molds 4 and middle columns 3. Therefore, only different middle columns 3 and upper molds 4 need to be purchased. From the perspective of the factory, only purchasing different middle columns 3 and upper molds 4 can greatly reduce costs, and different middle columns 3 and upper molds 4 can also be used in conjunction with each other, thereby achieving the effect of full utilization.

[0045] Example 2

[0046] Based on the first embodiment, Figure 3 and Figure 11 As shown, the lower mold 1 includes a lower mold body 11, the upper surface of the lower mold body 11 is provided with a mounting groove 13 and a positioning column 15, the bottom wall of the mounting groove 13 is provided with a feed port 12, and the inner wall of the mounting groove 13 is provided with a first protrusion 14;

[0047] Based on the above, the setting of the mounting groove 13 and the positioning column 15 enables the upper mold 4 to be directly inserted into the interior of the lower mold 1. At this time, the intermediate column 3 is set between the upper mold 4 and the lower mold 1. The mold can be completed by inserting it into the mold frame. The mold is made lighter and easier to use by removing the reinforcing tube 2.

[0048] Example 3

[0049] On the basis of embodiment 1 or 2, Figure 2 、 Figure 5 、 Figure 6 as well as Figure 8 As shown, the intermediate column 3 includes a bottom plate 31, which is arranged inside the cylinder 21 and located at the top of the partition 22. The upper surface of the bottom plate 31 is provided with a communication hole 33 and a column 34;

[0050] The side of the bottom plate 31 is provided with a side groove 32, and the first protrusion 14 can be inserted into the inside of the side groove 32. The diameter of the bottom plate 31 is consistent with the inner diameter of the mounting groove 13, and the diameter of the bottom plate 31 is larger than the inner diameter of the partition 22;

[0051] The column 34 includes a first column 341 and a second column 342. The first column 341 and the second column 342 are special-shaped columns with the same cross-sectional shape. The height of the second column 342 is smaller than that of the first column 341.

[0052] The upper mold 4 includes a mounting plate 41, a side of which is provided with a positioning slot 42, and the second protrusion 23 can be snapped into the interior of the positioning slot 42. A column 43 is provided at the top of the mounting plate 41, and a cover plate 44 is provided at the top of the column 43. The upper surface of the cover plate 44 is provided with an extrusion hole 45.

[0053] The extrusion hole 45 includes a first extrusion hole 451 , the cross-sectional shape of the first extrusion hole 451 is consistent with the cross-sectional shape of the first column 341 , and the size of the first extrusion hole 451 is larger than the size of the first column 341 ;

[0054] A positioning groove 46 is provided on the lower surface of the mounting plate 41. The positioning groove 46 is in communication with the extrusion hole 45. A third protrusion 47 is provided on the inner sidewall of the positioning groove 46. The third protrusion 47 can be inserted into the inner side groove 32.

[0055] Based on the above, the first column 341 cooperates with the first extrusion hole 451 to enable the mold to extrude the first hollow aluminum profile, and the second column 342 cooperates with the first extrusion hole 452 to extrude the second hollow aluminum profile. The second hollow aluminum profile is different from the first one only in the thickness of the aluminum profile. By setting columns 3 of different heights, the gap between the column 3 and the first extrusion hole 451 is different, and the thickness of the extruded hollow aluminum profile is different, thereby achieving an adjustable thickness effect.

[0056] Example 4

[0057] Based on the third embodiment, Figure 7 and Figure 9 The column 34 includes a third column 343 , and the third column 343 and the first column 341 are special-shaped columns with different cross-sectional areas;

[0058] The extrusion hole 45 includes a second extrusion hole 452 , the cross-sectional shape of the second extrusion hole 452 is consistent with the cross-sectional shape of the third column 343 , and the size of the second extrusion hole 452 is larger than the size of the third column 343 ;

[0059] Based on the above, the third column 343 and the second extrusion hole 452 cooperate with each other, so that the hollow aluminum profile extruded by the mold has a different shape from the hollow aluminum profile extruded in Example 3, that is, the effect of extruding different special-shaped hollow aluminum profiles is achieved.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
