[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 4 A hot extrusion die for an aluminum rod includes a base 1, a lifting plate 2 is provided above the base 1, a buffer component 14 is fixedly connected to the upper surface of the base 1, and the lifting plate 2 is slidably connected to the outer surface of the buffer component 14. The buffer component 14 can provide a buffering capacity for the lifting plate 2, and provide a buffer when the lower die 3 and the upper die 4 are combined, thereby improving the uniformity of force during extrusion and increasing the use effect of the device.

[0025] A lower mold 3 is provided on the upper surface of the base 1, and an upper mold 4 is provided on the bottom surface of the lifting plate 2. Two positioning blocks 5 are fixedly connected to the upper surface of the base 1, and each positioning block 5 is slidably connected to a first limit block 6 inside. The side surfaces of the two first limit blocks 6 that are close to each other extend to the inside of the lower mold 3, and the side surfaces of the two first limit blocks 6 that are away from each other are fixedly connected to two transmission rods 7. The ends of the two groups of transmission rods 7 that are away from each other pass through the positioning block 5 and extend to the outside of the positioning block 5. The ends of the two groups of transmission rods 7 that are away from each other are commonly fixedly connected to a first baffle 17, and the sides of the two first baffles 17 that are away from each other are fixedly connected to a first handle 18. Through the cooperation of the first baffle 17 and the first handle 18, an effective force point can be provided for the transmission rod 7, thereby increasing the convenience when pulling the transmission rod 7 and increasing the convenience of the device.

[0026] An auxiliary spring 8 is provided on the outer surface of each group of transmission rods 7. The ends of the two groups of auxiliary springs 8 that are close to each other are fixedly connected to the side of the first limit block 6 that is away from each other. The ends of the two groups of auxiliary springs 8 that are away from each other are fixedly connected to the inner wall of the positioning block 5. The auxiliary spring 8 can rely on its own rebound force to enable the transmission rod 7 to achieve reset ability, thereby improving the convenience of the transmission rod 7 in limiting the lower mold 3, and also increasing the stability during the limiting process.

[0027] Two support blocks 9 are fixedly connected to the bottom surface of the lifting plate 2, and a second limit block 11 is slidably connected to the inside of each support block 9. Four auxiliary holes 19 are opened in the interior of the lower mold 3, and a guide block 20 is fixedly connected to the bottom surface of the upper mold 4. Through the cooperation of the auxiliary holes 19 and the guide blocks 20, the upper mold 4 can provide guiding ability when extruding the lower mold 3, avoiding the possibility of mold deviation during extrusion, and increasing the use effect of the device.

[0028] The inner bottom wall of each auxiliary hole 19 is fixedly connected with an auxiliary rod 21, and the outer surface of each auxiliary rod 21 is sleeved with a buffer spring 22. The bottom end of each buffer spring 22 is fixedly connected to the inner bottom wall of the auxiliary hole 19. Relying on the cooperation of the auxiliary rod 21 and the buffer spring 22, the buffering capacity of the upper mold 4 when extruding the lower mold 3 can be further improved, and the uniformity of force during extrusion is increased.

[0029] The ends of the two second limit blocks 11 that are close to each other extend to the interior of the upper mold 4, and the sides of the two second limit blocks 11 that are away from each other are fixedly connected to two moving rods 12. The ends of the two groups of moving rods 12 that are away from each other pass through the support block 9 and extend to the outside of the support block 9. The ends of the two groups of moving rods 12 that are away from each other are commonly fixedly connected to a second baffle 23, and the sides of the two second baffles 23 that are away from each other are fixedly connected to a second handle 24. Through the cooperation of the second baffle 23 and the second handle 24, an effective force point can be provided for the moving rod 12, which increases the convenience when pulling the moving rod 12 and increases the convenience of the device.

[0030] The outer surface of each group of moving rods 12 is provided with a return spring 13, and the ends of the two return springs 13 that are close to each other are fixedly connected to the side of the second limit block 11 that is away from each other, and the ends of the two return springs 13 that are away from each other are fixedly connected to the inner wall of the support block 9. The return spring 13 can rely on its own rebound force to enable the moving rod 12 to achieve the reset ability, thereby improving the convenience of the moving rod 12 in limiting the upper mold 4, and also increasing the stability during the limiting process.

[0031] The working principle of the utility model is: when in use, first connect the lifting plate 2 to the external hydraulic device. When the aluminum rod needs to be extruded, the upper mold 4 is driven down by the external hydraulic device. The buffer assembly 14 can buffer the descending speed of the upper mold 4, and insert the guide block 20 into the auxiliary hole 19. The overlap of the two sides is used to avoid the possibility of movement of the lower mold 3 during extrusion. At the same time, the auxiliary rod 21 and the buffer spring 22 can further improve the buffering capacity during the extrusion process. When the appropriate pressure is reached, the upper mold 4 can be reset by the external hydraulic equipment. When the lower mold 3 needs to be disassembled and assembled, pull the first handle 18, and then the first baffle 17 drives the transmission rod 7 and the first limit block 6 to move into the positioning block 5, so that the auxiliary spring 8 contracts and moves out of the lower mold 3 at the same time. At this time, the lower mold 3 is not affected by the first limit block 6, thereby sliding the lower mold 3 out of the base 1. When it needs to be installed, reset the lower mold 3, release the first handle 18, and use the rebound force of the auxiliary spring 8 to push the first limit block 6 to insert it into the lower mold 3 again. When it is necessary to disassemble and assemble the upper mold 4, pull the second handle 24, and then make the second baffle 23 drive the moving rod 12 and the second limit block 11 to move into the support block 9 and move out of the upper mold 4, so that the upper mold 4 is not interfered with by the second limit block 11, thereby quickly sliding the upper mold 4 out of the two support blocks 9. When it needs to be installed, reset the upper mold 4 and release the second handle 24. Rely on the rebound force of the reset spring 13 to push the second limit block 11 to insert it into the upper mold 4, so that the mold can be conveniently disassembled and assembled, which effectively increases the practicality of the aluminum bar hot extrusion mold.
