TECHNICAL FIELD

[0001] The utility model relates to aluminum alloy extrusion die technical field especially relates to a kind of aluminum alloy extrusion die convenient to disassemble. BACKGROUND

[0002] Aluminum alloy is the most widely used non-ferrous structural material in industry, which has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. The rapid development of industrial economy has increased the demand for aluminum alloy welded structural parts, making the research on the weldability of aluminum alloy more in-depth. Currently, aluminum alloy is the most commonly used alloy. When aluminum alloy is subjected to pressure forming, an extrusion die is needed.

[0003] The existing extrusion die is usually composed of an upper die, a lower die and a die sleeve. During use, the upper die and the lower die are usually placed directly in the die sleeve without being fixed between them. This makes the two dies prone to looseness or even shift during extrusion, affecting the extrusion effect and resulting in substandard product quality.

[0004] In addition, the existing extrusion die is directly placed in the die sleeve without being fixed, which makes the die prone to slide out of the die sleeve during disassembly and replacement, resulting in wear and tear or even hitting the worker. SUMMARY

[0005] To overcome the shortcomings of the prior art, the utility model provides an aluminum alloy extrusion die convenient to disassemble, which has the advantages of facilitating disassembly and replacement of the die without stopping the machine, solving the problems raised in the background art.

[0006] The utility model provides the following technical scheme: an aluminum alloy extrusion die convenient to disassemble, comprising a die sleeve, an upper die and a lower die are arranged in the die sleeve respectively, the inner side of the die sleeve is circularly arrayed and provided with two sliding grooves, the outer side of the upper die and the lower die is circularly arrayed and provided with two mounting grooves, one end of the lower die close to the upper die is circularly arrayed and fixedly installed with two rectangular blocks, the two rectangular blocks are inserted into one end of the upper die, the two rectangular blocks are both provided with a connecting mechanism for connecting the upper die and the lower die together, and the mounting groove is provided with a fixing mechanism for fixing the upper die and the lower die in the die sleeve.

[0007] By adopting the above technical solution to fix the upper and lower molds together, it is possible to avoid the two molds from becoming loose or shifting during the extrusion of aluminum alloy, which would affect the extrusion effect. During use, the two molds are fixed in the mold sleeve by the fixing mechanism, which prevents the mold from slipping out of the mold sleeve when the workers disassemble the mold, thus preventing the mold from falling to the ground and causing wear or even hitting the workers.

[0008] Preferably, the connecting mechanism is a rod, and there are two rods. Both rods pass through the outer side of the upper mold and are respectively inserted into two rectangular blocks. The top ends of the two rods can slide in two grooves respectively.

[0009] By adopting the above technical solution to fix the upper and lower dies together, it is possible to avoid loosening or displacement between the two dies during the extrusion of aluminum alloy, which would affect the extrusion effect.

[0010] Preferably, the fixing mechanism includes limiting rods that are slidably installed in the two mounting slots. Slots are evenly provided on the outer side of the mold sleeve. One end of the limiting rod is inserted into the slot. An elastic element is provided between one end of the inner wall of the mounting slot and one end of the limiting rod. The elastic element is a spring, and the two ends of the spring are fixedly connected to one end of the inner wall of the mounting slot and one end of the limiting rod, respectively.

[0011] By using the above technical solution to fix the two molds inside the mold sleeve, it is possible to prevent the molds from slipping out of the mold sleeve when the workers disassemble the molds, which would cause the molds to fall to the ground and be worn, or even hit the workers.

[0012] Preferably, the spring is made of a high-temperature resistant material.

[0013] By adopting the above technical solution, the spring can still work normally under high temperature conditions.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 A disassembleable aluminum alloy extrusion die includes a die sleeve 1, an upper die 2 and a lower die 3 respectively disposed inside the die sleeve 1. Two sliding grooves 4 are arranged in a circular array on the inner side of the die sleeve 1. Two mounting grooves 5 are arranged in a circular array on the outer sides of both the upper die 2 and the lower die 3. Two rectangular blocks 6 are fixedly installed in a circular array at one end of the lower die 3 near the upper die 2. Both rectangular blocks 6 are inserted into one end of the upper die 2. Each of the two rectangular blocks 6 is provided with a connecting mechanism for connecting the upper die 2 and the lower die 3 together. A fixing mechanism is provided in the mounting groove 5 for fixing the upper die 2 and the lower die 3 inside the die sleeve 1.

[0027] Please see Figure 3 and Figure 7The connecting mechanism is a rod 7, and there are two rods 7. Both rods 7 pass through the outside of the upper mold 2 and are inserted into the two rectangular blocks 6 respectively. The tops of the two rods 7 can slide in the two sliding grooves 4 respectively. The rods 7 can also be replaced by screws, which can make the fixing effect between the two molds better.

[0028] Please see Figure 2 , Figure 4 and Figure 6 The fixing mechanism includes a limiting rod 8 that is slidably installed in two mounting slots 5. Slots 9 are evenly provided on the outer side of the mold sleeve 1. One end of the limiting rod 8 is inserted into the slot 9. An elastic element is provided between one end of the inner wall of the mounting slot 5 and one end of the limiting rod 8.

[0029] Please see Figure 2 The elastic element is a spring 10, and the two ends of the spring 10 are fixedly connected to one end of the inner wall of the mounting groove 5 and one end of the limiting rod 8, respectively.

[0030] Please see Figure 2 Spring 10 is made of high-temperature resistant material.

[0031] Working principle: In use, first insert the two rectangular blocks 6 at one end of the lower mold 3 into the inside of one end of the upper mold 2. Then, pass the insert rod 7 through the upper mold 2 until the insert rod 7 is inserted into the inside of the rectangular block 6. Alternatively, the insert rod 7 can be replaced by a screw. In this case, a threaded hole can be provided in the rectangular block 6. Then, pass the screw through the upper mold 2 and finally screw the screw into the threaded hole provided on the rectangular block 6. This combines the upper mold 2 and the lower mold 3 together, thereby preventing the upper mold 2 and the lower mold 3 from shifting during the extrusion process.

[0032] When installing the combined mold of upper mold 2 and lower mold 3 into mold sleeve 1, the operator can press the limiting rod 8, causing the limiting rod 8 to retract into the mounting groove 5 and squeeze the spring 10. Then, push the combined mold so that it can slide within mold sleeve 1. At this time, the top of the insert rod 7 will slide within the sliding groove 4 without restricting the combined mold. When the combined mold has completely slid into mold sleeve 1, the rebound force of the spring 10 will push the limiting rod 8 outward within the mounting groove 5 until one end of the limiting rod 8 is inserted into the slot 9, thereby fixing the combined mold. This ensures that upper mold 2 and lower mold 3 are fixed within mold sleeve 1, preventing the two molds from slipping out of mold sleeve 1 when disassembling or replacing upper mold 2 or lower mold 3. The combined mold is installed in the mold groove of the hot extruder. During extrusion, there will be a baffle at the end of mold sleeve 1 near lower mold 3. The baffle will abut against one end of mold sleeve 1 and one end of lower mold 3 to prevent the limiting rod 8 from deforming during extrusion.
