Technical Field

[0001] The utility model relates to the technical field of hot extrusion dies, in particular to a hot extrusion die for a guide rail aluminum profile. Background Art

[0002] Guide rails are grooves or ridges made of metal or other materials. They are usually made by hot extrusion. As aluminum extrusion technology becomes increasingly sophisticated, aluminum profile extrusion is a plastic processing method that applies external force to the metal billet placed in a container to make it flow out of a specific die hole to obtain the required cross-sectional shape and size. Most hot-deformed aluminum manufacturers use positive hot deformation and extrusion methods to obtain aluminum profiles that meet the required cross-sectional shape through specific dies.

[0003] Hot extrusion dies are generally divided into upper and lower dies. Existing aluminum profile hot extrusion dies are generally fixed by pins. However, the radius of the pins and the pin holes are generally set to the same size, which makes it difficult to align the positions of the pins and the pin holes. This easily increases the installation time of the die and is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the positions of the pins and the pin holes are not well aligned, which easily increases the installation time of the mold and is time-consuming and labor-intensive, and to propose a guide rail aluminum profile hot extrusion mold.

[0010] Preferably, a hexagonal positioning block is threadedly sleeved on the second threaded rod, and one surface of the hexagonal positioning block contacts the upper surface of the first adjustment block.

[0011] Preferably, the side of the pin is provided with anti-slip grooves, and the inner wall of the pin hole is symmetrically rotated with a push rod installed through a torsion spring, and the ends of the two push rods close to each other are in contact with the anti-slip grooves on the pin, and a limit plate is symmetrically fixedly installed in the pin hole, and the limit plate is located below the push rod.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figure 1-Figure 5 A hot extrusion die for a guide rail aluminum profile comprises an upper die 1 and a lower die 2. Pin holes are symmetrically opened on the upper die 1, and pins 3 are vertically symmetrically fixedly installed on the lower die 2. The diameter of the pin holes is larger than the diameter of the pins 3. When installing the die, the setting of the pin holes and the pins 3 can facilitate the alignment of the positions of the pins 3 and the pin holes, and the insertion of the pins 3 into the pin holes.

[0025] A bracket 4 is symmetrically fixedly installed on the upper mold 1, and the two brackets 4 are respectively located above the two pin holes. A first threaded hole is opened on the bracket 4, and a first threaded rod 5 is threadedly inserted in the first threaded hole. A connecting disk 6 is rotatably installed on the lower end of the first threaded rod 5, and a plurality of trapezoidal blocks 7 are fixedly installed on the lower surface of the connecting disk 6. The inclined surfaces of the plurality of trapezoidal blocks 7 are all facing the axis of the connecting disk 6. A first adjusting block 8 is fixedly installed on the upper end of the first threaded rod 5, and a pin 3 is inserted in the pin hole. A connecting component for connecting the pin 3 is provided on the first threaded rod 5.

[0026] After the pin is inserted into the pin hole, the first threaded rod 5 can be driven to rotate by rotating the first adjusting block 8. Under the action of the bracket 4, the connecting disk 6 is driven to move into the pin hole, and then the multiple trapezoidal blocks 7 are driven to be inserted into the pin hole through the connecting disk 6 and contact with the pin 3 in the pin hole. Since the inclined surfaces of the trapezoidal blocks 7 are all facing the axis of the connecting disk 6, the pin 3 will contact the inclined surfaces of the multiple trapezoidal blocks 7. The multiple trapezoidal blocks 7 can play a positioning role for the pin 3, positioning the pin 3 at the axis of the pin hole, and then the first threaded rod 5 and the pin 3 are connected together through the connecting assembly. The operation is simple, time-saving and labor-saving, and work efficiency is effectively improved.

[0027] A second threaded hole is provided through the first adjusting block 8, the first threaded rod 5 and the connecting disk 6, and a threaded groove is provided on the top of the pin 3. The connecting assembly includes a second threaded rod 9 threadedly inserted in the second threaded hole and a second adjusting block 10 fixedly installed at one end of the second threaded rod 9. The end of the second threaded rod 9 away from the second adjusting block 10 is threadedly inserted in the threaded groove, and a hexagonal positioning block 11 is threadedly sleeved on the second threaded rod 9. One side of the hexagonal positioning block 11 contacts the upper surface of the first adjusting block 8. The first threaded rod 5 and the second threaded rod 9 are both rotatably set on the axis of the connecting disk 6.

[0028] Since the first threaded rod 5 and the second threaded rod 9 are both rotatably set on the axis of the connecting plate 6, when the pin 3 is positioned on the axis of the pin hole through multiple trapezoidal blocks 7, one end of the second threaded rod 9 is aligned with the thread groove of the pin 3. At this time, the second adjusting block 10 can be rotated to drive the second threaded rod 9 to rotate, driving one end of the second threaded rod 9 to move into the pin hole. One end of the second threaded rod 9 will be threaded into the thread groove, and the first threaded rod 5 and the pin 3 are connected together through the second threaded rod 9, thereby realizing the installation of the mold.

[0029] When one end of the second threaded rod 9 is inserted into the thread groove, the hexagonal positioning block 11 can be rotated so that one side of the hexagonal positioning block 11 contacts the upper surface of the first adjustment block 8. Under the action of the hexagonal positioning block 11, the second threaded rod 9 can be prevented from loosening.

[0030] Anti-slip grooves are provided on the side of the pin 3, and a push rod 12 is installed on the inner wall of the pin hole symmetrically through a torsion spring. The ends of the two push rods 12 that are close to each other are in contact with the anti-slip grooves provided on the pin 3. A limit plate 13 is symmetrically fixedly installed in the pin hole. The limit plate 13 is located below the push rod 12. A plurality of through holes are provided on the surface of the upper mold 1, which are respectively connected to the two pin holes. A pull rope 14 is inserted into the through hole. One end of the pull rope 14 extending into the pin hole is fixedly connected to one end of the push rod 12, and the other end of the pull rope 14 is fixedly installed with a pull ring 15.

[0031] Under the action of the torsion force of the torsion spring, the push rod 12 contacts the limit plate 13. At this time, the push rod 12 will be in a horizontal state. When the pin 3 is inserted into the pin hole, the pin 3 will drive the push rod 12 to rotate. One end of the push rod 12 will contact the anti-slip groove on the pin 3. The anti-slip groove can increase the friction between the push rod 12 and the pin 3. When the pin 3 tends to move out of the pin hole, the push rod 12 can limit the pin 3 from moving out of the pin hole. When the mold needs to be disassembled to release the restriction on the pin 3, the pull ring 15 can be pulled to drive the push rod 12 to rotate through the pull rope 14, so that one end of the push rod 12 is separated from the pin 3.

[0032] In the present invention, after the pin is inserted into the pin hole, the first threaded rod 5 can be driven to rotate by rotating the first adjusting block 8. Under the action of the bracket 4, the connecting disk 6 is driven to move into the pin hole, and then the multiple trapezoidal blocks 7 are driven to be inserted into the pin hole through the connecting disk 6 and contact with the pin 3 in the pin hole. Since the inclined surfaces of the trapezoidal blocks 7 are all facing the axis of the connecting disk 6, the pin 3 will contact the inclined surfaces of the multiple trapezoidal blocks 7. The multiple trapezoidal blocks 7 can play a positioning role for the pin 3, positioning the pin 3 at the axis of the pin hole, and then the first threaded rod 5 and the pin 3 are connected together through the connecting assembly. The operation is simple, time-saving and labor-saving, and work efficiency is effectively improved.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
