Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an aluminum profile extrusion die convenient for material taking, including an upper die 1 and a lower die 4 that are stacked and spliced with each other. A die core 23 is provided at the center of one side of the upper die 1. A forming die cavity 13 for accommodating the die core is provided in the middle of the lower die 4. The die core 23 is placed in the forming die cavity 13 and there is a flow gap between the two. And a plurality of shunt channels 11 penetrating both sides of the upper die 1 are provided around the die core 23.

[0028] As Figure 1 and Figure 2 shown, the present utility model further includes a seat body for installing the upper die 1 and the lower die 4. The seat body includes a base 18. The base 18 can be installed on an extruder through bolts. Two limit supports 17 are symmetrically installed at the top of the base 18. The upper die 1 and the lower die 4 are arranged between the two limit supports 17, that is, after the upper die 1 and the lower die 4 are butted, they are fixed in the two limit supports 17.

[0029] As Figure 3 shown, one end of the lower die 4 away from the upper die 1 extends outside the limit support 17, and a rectangular shear cut 14 is opened at the center of the side surface of the lower die 4 outside the limit support 17. The rectangular shear cut 14 is a through hole and is perpendicular to the axis of the lower die 4. The height of the rectangular shear cut 14 is greater than the height of the forming die cavity 13;

[0030] A shear plate 7 is movably arranged within the rectangular shear opening 14. One end of the shear plate 7 extends outside the lower die 4, and a telescopic mechanism 20 capable of driving the shear plate 7 to expand and contract within the rectangular shear opening 14 is provided on the base 18. In the initial state, the end of the shear plate 7 away from the telescopic mechanism 20 is located on one side of the forming die cavity 13. When the telescopic mechanism 20 extends, the shear plate 7 passes through the forming die cavity 13 and cuts off the aluminum profile.

[0031] In the middle of the side of the upper die 1 away from the lower die 4, a feed inlet 12 is provided. The shunt channel 11 is located within the feed inlet 12. A positioning boss 24 is provided on the side of the upper die 1 away from the feed inlet 12, and the shunt channel 11 penetrates through the positioning boss 24;

[0032] In the middle of the side of the lower die 4 away from the shear plate, a welding chamber 6 is provided. The forming die cavity 13 is located within the welding chamber 6. A positioning groove 2 corresponding to the positioning boss 24 is provided at the edge of the welding chamber 6, and the positioning boss 24 is placed within the positioning groove 2. The function of the welding chamber 6 is to gather the metal flowing out from the shunt holes and re-weld them together to form an integral blank centered on the die core. Due to the continuous aggregation of the metal, the static pressure continuously increases until extrusion molding;

[0033] Specifically, the side of the shear plate 7 close to the forming die cavity 13 is in a knife-edge shape. As Figure 4 shown, the end face of the die core 23 is tangent to the shear plate 7. Because in actual application, the extruder extrudes the aluminum material towards the inside of the shunt channel 11, allowing the aluminum material to enter the shunt channel 11 and then enter the welding chamber 6. The aluminum material in the welding chamber 6 is extruded and formed after passing through the gap formed between the die core and the forming die cavity 13;

[0034] When an extrusion of a profile is completed, the telescopic mechanism 20 extends to drive the shear plate 7 through the rectangular shear opening 14, so that the shear plate 7 cuts off the profile within the forming die cavity 13, facilitating the removal of the profile from the lower die 4.

[0035] Further, as Figure 1 shown, the telescopic mechanism 20 includes a mounting frame 21 installed at one end of the base 18. A hydraulic cylinder perpendicular to the axis of the lower die 4 is installed at the top of the mounting frame 21. The telescopic shaft of the hydraulic cylinder is connected to the end of the shear plate 7 away from the lower die 4. A first strip-shaped seat 8 is provided at the end of the shear plate 7 away from the lower die 4, and the end of the telescopic shaft of the hydraulic cylinder is connected to a second strip-shaped seat 19. The second strip-shaped seat 19 and the first strip-shaped seat 8 are fastened by bolts. When it is necessary to replace the shear plate 7, the hydraulic cylinder is retracted to the shortest, the shear plate is pulled out from the rectangular shear opening 14, and then the second strip-shaped seat 19 and the first strip-shaped seat 8 are disassembled to replace.

[0036] Further, as Figure 1 and Figure 2As shown in the figure, mounting surfaces 10 perpendicular to the base 18 are provided on both sides of the upper die 1 and the lower die 4, and there is a clearance fit between the mounting surface 10 and the shear plate 7;

[0037] Screw holes 9 are provided on the mounting surface 10, mounting holes 15 corresponding to the screw holes are provided on the limit support 17, fastening bolts are provided in the mounting holes 15, and strip-shaped retaining seats 16 in contact with the side surface of the upper die 1 are provided on the side walls of both ends of the two limit supports 17 close to the upper die 1, so that the upper die and the lower die can be stably fixed on the limit support 17 without shaking.

[0038] Furthermore, at least one positioning block 22 is provided on the surface of the positioning boss 24, positioning holes 5 corresponding to the positioning blocks 22 are provided on the inner surface of the positioning groove 2, and the positioning blocks 22 are placed in the positioning holes 5. Through the cooperation of the positioning blocks 22 and the positioning holes 5, the connection between the molds can be made more stable, and a plurality of fastening holes 3 are provided at the edges of the upper die 1 and the lower die 4, and the fastening holes 3 on both sides are connected by bolts to connect the upper die and the lower die into a whole.

[0039] When the utility model is in use, the base 18 is installed on the extruder, the feed inlet 12 is facing the push rod of the extruder, and under the push of the push rod, the aluminum material first enters the feed inlet 12, and then the aluminum material enters the welding chamber 6 through each shunt channel 11. With continuous extrusion, the aluminum material in the welding chamber 6 finally extrudes from the lower die 4. When the extruded profile reaches the preset length, the telescopic mechanism 20 is controlled to drive the shear plate 7 to shear the profile located in the lower die 4, which is convenient for taking out the profile;

[0040] It should be emphasized that there is still residual aluminum material inside the welding chamber, which does not need to be worried about. When the next aluminum material is extruded, the residual aluminum material will be mixed with the next aluminum material and then extruded again, and so on.
