[0002] When producing aluminum alloy door and window profiles, a profile extrusion die is needed. Commonly used extrusion dies are often composed of only one template. There is no buffer between the forming template and the aluminum ingot, resulting in a large difference in the flow rate of the metal in each part of the cross section, which will cause the extruded profile to deform. Moreover, the same die can only be used to extrude one type of aluminum alloy door and window profile. Therefore, traditional profile extrusion dies have low production efficiency and high production costs, and it is difficult to meet production needs.

[0003] According to the authorization announcement number CN213033278U, a variable-section aluminum profile extrusion die is provided, including an upper die and a lower die that cooperate with each other, the upper die has a guide hole and a protrusion, and the lower die has a forming hole and a groove, the forming hole is arranged inside the groove, and the forming hole has at least two different shapes, the upper die and the lower die are clamped by positioning pins and fasteners. When in use, only one of the templates needs to be rotated a certain angle, and then the two templates are clamped together, so that two or more different types of profile products can be produced using a set of molds, thereby improving the mold utilization rate and production efficiency: However, this extrusion mold is a separate structure. When different types of profile products need to be manufactured, the upper die and the lower die need to be repeatedly separated and then rotated and covered, which is more troublesome to operate. For this reason, we provide a variable-section aluminum profile extrusion die. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Example 1

[0024] In one embodiment, Figure 1-Figure 4 As shown, an aluminum profile extrusion die with a variable cross-section includes an upper die 1 and a lower die 2 that cooperate with each other, the upper die 1 is formed with two symmetrically distributed flow guide holes 3, the lower die 2 is formed with a plurality of circumferentially equidistantly distributed forming holes 4 and grooves 5, and the forming holes 4 are located inside the grooves 5 in a one-to-one correspondence; a matching component is provided between the upper die 1 and the lower die 2, and the matching component is used to allow the two to perform limited rotation, so as to achieve the effect of cross-section transformation without separating the upper die 1 and the lower die 2, and only needing to directly rotate;

[0025] The matching component includes an annular groove 6, which is opened at the top of the lower mold 2, and a movable groove 7 is opened on the outer wall of the lower mold 2 connected to the side of the annular groove 6. A slider 8 is fixedly connected to the bottom end of the upper mold 1, and a connecting rod 9 is fixedly connected to the side wall of the slider 8. The slider 8 and the connecting rod 9 are slidably connected to the inner sides of the annular groove 6 and the movable groove 7 respectively. One end of the connecting rod 9 passes through the movable groove 7 to the outer side of the lower mold 2 and is fixedly connected to an outer sliding ring 10. Through the limited rotation of the slider 8, the connecting rod 9 and the outer sliding ring 10 along the annular groove 6 and the movable groove 7, a stable limited rotation between the upper mold 1 and the lower mold 2 can be achieved, and the height of the outer sliding ring 10 is greater than the opening height of the movable groove 7 to protect the inner side of the groove body. The outer wall of the outer sliding ring 10 is fixedly connected with a rotating block 11 that is easy to pull;

[0026] A convex ring 12 is formed on the outer wall of the bottom end of the lower mold 2, and a locking assembly is arranged on the top of the convex ring 12. The locking assembly is used to limit and fix the rotating block 11, so as to indirectly fix and lock the upper mold 1 and the lower mold 2. The locking assembly includes a receiving groove 13, which is circumferentially equidistantly arranged on the outer edge of the top end of the convex ring 12, and a torsion spring 14 is fixedly connected to the inner side of the receiving groove 13. A rotating magnetic block 15 is fixedly connected to the top end of the torsion spring 14. The torsion spring 14 is used to ensure that the rotating magnetic block 15 is in a horizontal state. The rotating magnetic block 15 is fixedly connected to the outer side of the rotating block 11, wherein the rotating magnetic block 15 is a U-shaped structure, which can well fix and limit the rotating block 11 in the horizontal direction, and the inner edge of the rotating magnetic block 15 close to the lower mold 2 is set to a rounded edge structure, and this rounded structure is to facilitate the rotating magnetic block 15 to be flipped along the arc surface to be connected with the rotating block 11;

[0027] The two forming holes 4 located at opposite corners are of the same pattern model. The rotating block 11 is located on the axis formed by the two guide holes 3. The opening position of each accommodating groove 13 is correspondingly distributed on the axis formed by each group of forming holes 4 with the same pattern. The corresponding distribution of the positions of the forming holes 4, the rotating block 11 and the accommodating groove 13 is to ensure that when the rotating magnetic block 15 in the accommodating groove 13 limits the rotating block 11, a group of forming holes 4 located at opposite corners and of the same model can just overlap with the guide hole 3 to achieve the effect of changing the mold model. Example 2

[0028] The outer wall of the outer slip ring 10 is located on both sides of the rotating block 11 and is embedded with symmetrically distributed fixed magnets 16. The two fixed magnets 16 are attracted to the vertical rods on both sides of the rotating magnet 15. The fixed magnets 16 and the rotating magnets 15 are attracted to each other by magnetic force, which increases the limiting locking effect of the rotating magnets 15 on the rotating block 11, thereby ensuring the stability of the locking between the upper mold 1 and the lower mold 2.

[0029] Working principle: When using this device for mold manufacturing, first flip the rotating magnetic block 15 clamped on the outer side of the rotating block 11 downward, and the rotating magnetic block 15 is disengaged from the fixed magnetic blocks 16 on both sides of the rotating block 11, and under the action of the torsion spring 14, the rotating magnetic block 15 will remain in a horizontal state to release its limit on the rotating block 11, and then the rotating block 11 can be pulled to rotate the outer slip ring 10, and the connecting rod 9 and the slider 8 fixed on the inner side of the outer slip ring 10 rotate synchronously with the upper mold 1, and when the forming hole 4 corresponding to the model mold to be made is exposed to the guide hole 3, flip the corresponding rotating magnetic block 15 upward so that it is accurately clamped on the outer side of the rotating block 11 along the arc surface, and the rotating magnetic block 15 is attracted with the fixed magnetic blocks 16 on both sides of the rotating block 11, so as to achieve stable limit locking of the rotating block 11 and the upper mold 1 and the lower mold 2. This structure is simple and convenient to operate, and effectively simplifies the cumbersome operation of repeatedly separating the upper mold and the lower mold and then rotating and covering them, thereby improving the production efficiency of the mold.

[0030] The above-mentioned embodiment discloses an aluminum profile extrusion die with a variable cross-section, wherein a matching component is arranged between the upper die 1 and the lower die 2, and the slider 8, the connecting rod 9, and the outer sliding ring 10 are utilized to rotate along the ring groove 6 and the movable groove 7. The effect of making molds of different types can be achieved by directly rotating, thereby simplifying the operation method; at the same time, a convex ring 12 and a locking component arranged on the convex ring 12 are formed at the bottom end of the lower die 2, and the rotation adjustment and fixed locking of the upper die 1 and the lower die 2 can be achieved by a simple operation of flipping the rotating magnetic block 15 to make it fixedly engaged or disengaged with the rotating block 11, thereby improving the stability of mold manufacturing.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
