DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Reference is made to Figures 1-6 ​​The utility model relates to a high thermal conductivity aluminum alloy bar production mould, including lower mould 1 and upper mould 2, upper mould 2 movable setting is in the top of lower mould 1, and the bottom of upper mould 2 is fixedly arranged with the detachable pressure surface 3, and the top of pressure surface 3 is fixedly vertically arranged with threaded column 32, and the inside of upper mould 2 is correspondingly adapted to open threaded cavity 24 with threaded column 32.

[0023] Wherein, the upper mould 2 is driven by the external hydraulic rod assembly, and the production of aluminum alloy bar can be realized by the pressing between the upper mould 2 and the lower mould 1. It is worth noting that the specific structure between the lower mould 1 and the upper mould 2 and its working mode are prior art, so no more description is made.

[0024] Wherein, the bottom of upper mould 2 is upwardly provided with a plurality of upper limiting cavities 23, the top of each upper limiting cavity 23 is communicated with the ring cavity 22, and each upper limiting cavity 23 is adapted with the lower limiting cavity 31 and the limiting column 41.

[0025] Wherein, the two sides of the pressure ring 4 are fixedly provided with adjusting members 42, and the two sides of the ring cavity 22 in the upper mould 2 are adapted to open movable cavities 21 corresponding to the adjusting members 42. The vertical magnetic guide columns 25 are fixedly arranged in the movable cavities 21, and the guide cavities 43 corresponding to the magnetic guide columns 25 are adapted to open on the adjusting members 42. By the arrangement of the magnetic guide columns 25, the adjusting members 42 can be guided, so that the stability of the adjusting members 42 and the pressure ring 4 during movement can be improved.

[0026] Wherein, the inner wall of the movable cavity 21 is paved with a sealing sleeve, and the detachable magnetic member 5 is movably arranged in the movable cavity 21. The outer wall of the magnetic member 5 is also provided with a sealing sleeve synchronously, which can not only increase the friction of the magnetic member 5 in the movable cavity 21 to prevent the magnetic member 5 from falling off, but also improve the sealing property of the upper mould 2.

[0027] Wherein, the magnetic member 5 and the magnetic guide column 25 are adapted to be attracted, and the sum of the height of the magnetic member 5 and the adjusting member 42 is the same as the height of the movable cavity 21. By the arrangement of the magnetic force, the magnetic member 5 can be adsorbed on the magnetic guide column 25 to prevent the magnetic member 5 from falling off. It is worth noting that the outer side of the magnetic member 5 is provided with a buckle groove to facilitate the user to remove the magnetic member 5.

[0028] In this embodiment, the production of aluminum alloy bar can be realized by the cooperation between the lower mould 1 and the upper mould 2. The pressure surface 3 is fixedly installed on the upper mould 2, and when the pressure surface 3 is worn after long-term use, the user only needs to disassemble and replace the pressure surface 3. The whole upper mould 2 does not need to be replaced, which saves the maintenance cost.

[0029] Further, when the user needs to replace the pressing surface 3, the user only needs to take out the magnetic members 5 on both sides of the upper die 2 from the movable cavities 21. In this way, the magnetic members 5 can be removed from the pressing of the adjusting members 42, and at this time, the user can lift the pressing ring 4 upward through the adjusting members 42 on both sides, so as to drive the limiting columns 41 to move upward synchronously, so that the limiting columns 41 can be retracted into the upper limiting cavities 23. Then, the user only needs to insert the magnetic members 5 into the movable cavities 21 again and make the magnetic members 5 located at the bottom of the adjusting members 42, so as to prevent the adjusting members 42 from falling down through the magnetic members 5. Finally, the user only needs to rotate the pressing surface 3 to drive the threaded columns 32 to rotate synchronously, and rotate the threaded columns 32 out of the threaded cavities 24, so as to realize the dismounting of the pressing surface 3.

[0030] Then, the user can take out a new pressing surface 3 and rotate the threaded columns 32 on the pressing surface 3 into the threaded cavities 24 on the upper die 2. When the threaded columns 32 are completely inserted into the threaded cavities 24, the lower limiting cavities 31 and the upper limiting cavities 23 are adapted and aligned. At this time, the user can take out the magnetic members 5 in the movable cavities 21 on both sides again, so that the adjusting members 42 and the pressing ring 4 can automatically fall down through the gravity of the adjusting members 42 and the pressing ring 4, thereby driving the limiting columns 41 to fall down synchronously. In this way, the limiting columns 41 in the upper limiting cavities 23 can fall into the lower limiting cavities 31, so that the threaded columns 32 can be prevented from rotating during use through the clamping of the limiting columns 41 and the lower limiting cavities 31, thereby improving the installation stability of the pressing surface 3. Finally, the user inserts the magnetic members 5 into the movable cavities 21 and above the adjusting members 42, so as to realize the fixation of the adjusting members 42 and the pressing ring 4.

[0031] In the utility model, the production of aluminum alloy metal bars can be realized through the adaptation between the lower die 1 and the upper die 2. The pressing surface 3 can be fixedly installed at the bottom of the upper die 2 through the clamping between the threaded columns 32 and the threaded cavities 24 and the clamping between the limiting columns 41 and the lower limiting cavities 31. In this way, when the pressing surface 3 is worn, the user only needs to replace the pressing surface 3, thereby saving the maintenance cost of the upper die 2.

[0032] The above is only a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
