Description

Technical Field

[0001] This invention belongs to the field of mold assembly technology, specifically relating to a high-precision aluminum profile extrusion mold for new energy power batteries. Background Technology

[0002] Currently, most new energy vehicles on the market use power batteries as their power source. In the entire power battery module production process, to meet the design requirements of high strength and low weight, the casings and brackets of the power battery module are typically made of aluminum alloy. The brackets for the power battery are usually formed by extruding aluminum alloy rods using an extrusion die. To meet the high precision requirements of the power battery brackets, the related extrusion dies are often made of high-density steel such as tungsten carbide. Therefore, a high-precision aluminum profile extrusion die for a new energy power battery, with the same volume, is heavier than other types of extrusion dies. Furthermore, the extrusion die is usually designed as a cylinder; therefore, during storage, it is often placed on a die rack whose main body is made of two angle steel rods (as shown in the instruction manual). Figure 1 As shown in the figure, it is particularly difficult to move the extrusion die along the angle steel on the die placement rack for use or placement. Therefore, in order to address the above problem, we propose a high-precision aluminum profile extrusion die for new energy power batteries. Summary of the Invention

[0003] To overcome the problems existing in related technologies, this invention discloses a high-precision aluminum profile extrusion die for new energy power batteries.

[0004] To achieve the above objectives, one technical solution adopted by the present invention is:

[0005] A high-precision aluminum profile extrusion die for new energy power batteries includes a first die and a second die. The first die has two opposing first assembly slots on its circumferential surface, and each of the two first assembly slots is provided with a support mechanism.

[0006] The support mechanism includes a rotating arm rotatably disposed in the first assembly slot, and the rotating arm is provided with a support member that can rotate relative to the rotating arm;

[0007] When both of the rotating arms rotate to abut against the top wall of the corresponding first mounting slot, the two support members will extend out of the corresponding first mounting slot;

[0008] The two support members can be rotated into the corresponding first assembly slots along with the corresponding rotating arms.

[0009] Furthermore, the support mechanism also includes a round rod disposed on the side of the rotating arm near the first mold assembly surface, and a first round hole is provided on the wall of the first assembly groove near the first mold assembly surface, and the round rod is assembled with the first round hole.

[0010] Furthermore, the round rod is a threaded rod, the first round hole is a threaded hole, the round rod is threadedly connected to the first round hole, and the first round hole penetrates the mating surface of the first mold;

[0011] The second mold has two second circular holes on its mating surface that match the two circular rods. Both second circular holes are threaded holes. When the second mold is assembled with the first mold, the two second circular holes will respectively mate with the two first circular holes, and the internal threads of the second circular holes will be continuous with the internal threads of the corresponding first circular holes.

[0012] In the same support mechanism, when the rotating arm rotates out of the first assembly slot, the round rod will move axially toward the mating surface of the first mold. When the rotating arm abuts against the top wall of the first assembly slot, the round rod will extend out of the first round hole.

[0013] Furthermore, the support mechanism also includes an elastic element disposed on the side of the rotating arm away from the round rod for pushing the rotating arm toward the first mold mating surface.

[0014] Furthermore, the connection between the round rod and the rotating arm is a detachable connection.

[0015] Furthermore, a third circular hole is provided on the side of the rotating arm for the insertion of the circular rod. The third circular hole is a threaded hole. A fourth circular hole is provided on the side of the rotating arm away from the third circular hole. A fifth circular hole is provided at the end of the circular rod that is inserted into the third circular hole. The fifth circular hole is a threaded hole. A fastening bolt that is threaded into the fifth circular hole is inserted into the third circular hole.

[0016] Furthermore, the first mold has two second mounting grooves at the end away from the mating surface. The two second mounting grooves are respectively connected to the two first assembly grooves, and the two second mounting grooves correspond to the positions of the two fastening bolts.

[0017] Furthermore, both of the second mounting slots are threaded with sealing blocks, and the ends of the two elastic elements away from the first mold mating surface extend into the corresponding second mounting slots and abut against the corresponding sealing blocks.

[0018] Furthermore, the support member is a limiting wheel with a limiting annular groove on its circumferential surface.

[0019] Furthermore, the first mold has a plurality of bolt assembly holes at one end away from the mating surface, and two of the bolt assembly holes are respectively connected to two first assembly slots, and the bolts assembled in the bolt assembly holes can extend into the first assembly slots.

[0020] When the rotating arm rotates into the corresponding first assembly slot, the bolt extending into the first assembly slot can prevent the rotating arm from rotating out of the first assembly slot.

[0021] This invention discloses a high-precision aluminum profile extrusion die for new energy power batteries. When the two rotating arms of the first die of the extrusion die rotate out, the support members on the rotating arms can abut against the angle steel on the die placement frame, so that the entire extrusion die can be moved by rolling on the angle steel through the two support members. This reduces the difficulty of picking up or placing the extrusion die and improves work efficiency to a certain extent. Attached Figure Description

Detailed Implementation

[0035] The invention will now be further described with reference to the accompanying drawings.

[0036] Reference Figure 2-10 As shown in the figure, a high-precision aluminum profile extrusion die for new energy power batteries in this embodiment includes a first die 1 and a second die 2. The first die 1 has two opposing first assembly slots 11 on its circumference, and a support mechanism 3 is provided in each of the two first assembly slots 11. The first assembly slots 11 can be directly machined by a CNC machine tool, or they can be initially formed in the casting of the first die 1 and then precision machined by a CNC machine tool.

[0037] In this embodiment, the support mechanism 3 includes a rotating arm 31 rotatably disposed in the first assembly groove 11. The rotating arm 31 is provided with a support member 32 that can rotate relative to the rotating arm 31. In this embodiment, the support member 32 is a limiting wheel 321 with a limiting ring groove 322 on the side.

[0038] By rotating the rotating arms 31 to the first mold 1, when the extrusion module is placed on the mold placement rack 4, both rotating arms 31 can rotate to abut against the top wall of the corresponding first assembly slot 11, so that the two limiting wheels 321 extend out of the corresponding first assembly slot 11. Thus, the two limiting wheels 321 abut against the two angle steels 41 of the mold placement rack 4. Under the weight of the first mold 1 and the support of the angle steels 41, the rotating arms 31 on both sides will remain in the rotated-out state. At this time, the operator can support the first mold 1, allowing it to contact the mold placement rack 4 only through the two limiting wheels 321. This allows the operator to easily push the first mold 1 along the angle steels 41.

[0039] It is worth mentioning that, in practical applications, the first mold 1 and the second mold 2 are precisely assembled. Therefore, corresponding alignment grooves and alignment protrusions are set on their respective mating surfaces to prevent the first mold 1 and the second mold 2 from moving laterally after assembly. Based on this, when the first mold 1 is supported and only contacts the mold placement frame 4 through two limiting wheels 321, the mating surface of the first mold 1 can be tilted upwards. In this way, the second mold 2 can remain assembled with the first mold 1, and thus the second mold 2 can move together with the first mold 1. Compared with dragging the extrusion mold directly in contact with the angle steel 41, this saves physical effort and reduces the difficulty of moving the extrusion mold on the mold placement frame 4. In addition, this movement can also greatly improve the movement efficiency. During the movement, the limiting ring groove 322 can be engaged with the tip of the top of the angle steel 41, thus preventing the first mold 1 from shifting left or right during the movement along the angle steel 41.

[0040] In this embodiment, a specific configuration is made for the rotational connection between the support member 32 and the rotating arm 31. Specifically, the end of the rotating arm 31 has a sleeve shaft 315, and the end of the sleeve shaft 315 has a bolt hole 316. The limiting wheel 321 is sleeved on the outside of the sleeve shaft 315 through the central shaft hole. An internal hex bolt 318 is tightened in the bolt hole 316. The bolt part of the internal hex bolt 318 is fitted with a circular baffle 317 for limiting the limiting wheel 321 from disengaging from the sleeve shaft 315.

[0041] When storing the extrusion mold, after the extrusion mold is moved to the target position, the first mold 1 and the second mold 2 can be tilted to the side of the second mold 2 so that the second mold 2 abuts against the two angle steels 41. In this way, the extrusion mold can be placed on the mold placement rack 4 for storage.

[0042] In this embodiment, in order to enable the rotating arm 31 to be rotatably disposed in the first assembly groove 11, the support mechanism 3 is also provided with a round rod 33 disposed on the side of the rotating arm 31 near the joint surface of the first mold 1. In addition, a first round hole 111 is provided on one wall of the first assembly groove 11 near the joint surface of the first mold 1. The round rod 33 is inserted into the first round hole 111 and can rotate within the first round hole 111. In this way, the rotating arm 31 is rotatably disposed in the first assembly groove 11.

[0043] To ensure a tight connection between the first mold 1 and the second mold 2 during movement or storage, this embodiment incorporates the following design: Specifically, the round rod 33 is a threaded rod, and the first round hole 111 is a threaded hole. The round rod 33 is threadedly connected to the first round hole 111, which penetrates the mating surface of the first mold 1. Furthermore, the mating surface of the second mold 2 has two second round holes 21 that match the two round rods 33; both second round holes 21 are threaded holes. When the second mold 2 and the first mold 1 are assembled, the two second round holes 21 will respectively mate with the two first round holes 111, and the internal threads of the second round holes 21 will be continuous with the internal threads of the corresponding first round holes 111. Additionally, in the same support mechanism 3, when the rotating arm 31 rotates out of the first assembly slot 11, the round rod 33 will move axially towards the mating surface of the first mold 1. When the rotating arm 31 abuts against the top wall of the first assembly slot 11, the round rod 33 will extend out of the first round hole 111.

[0044] Based on the above settings, after the second mold 2 and the first mold 1 are assembled, when the rotating arm 31 is rotated out of the first assembly slot 11, since the round rod 33 is threadedly connected to the first round hole 111, the round rod 33 will move axially toward the assembly surface of the first mold 1 and rotate in the positive axial direction. When the round rod 33 extends out of the first round hole 111, since the second round hole 21 has been assembled with the first round hole 111 and the internal threads of the two are continuous, the round rod 33 extending out of the first round hole 111 will be screwed into the second round hole 21. In other words, the round rod 33 will be threadedly connected to the second round hole 21. Furthermore, since the support member 32 will always remain in the rotated-out state under the gravity of the first mold 1 and the second mold 2 and the support of the angle steel 41, when the extrusion mold is supported on the mold placement frame 4 by the support member 32, the round rod 33 will not exit the second round hole 21. In this way, the second mold 2 will be tightly connected to the first mold 1 by the two round rods 33. Thus, when the extrusion mold is moved on the mold placement frame 4, the first mold 1 and the second mold 2 do not need to be supported separately. This can further reduce the difficulty of moving the entire extrusion mold on the mold placement frame 4 and improve production efficiency to a certain extent.

[0045] It is worth mentioning that, since the first mold 1 and the second mold 2 are kept tightly joined together by the support mechanism 3 during storage, dust and other objects are prevented from falling onto the joint surfaces of the first mold 1 and the second mold 2. This protects the first mold 1 and the second mold 2, ensuring the processing accuracy of the extrusion dies and extending their service life. Furthermore, storing the first mold 1 and the second mold 2 tightly together prevents one of the dies from being lost or mixed with other extrusion dies, avoiding unnecessary problems.

[0046] When the first mold 1 is installed with the extrusion machinery and is ready to extrude the aluminum alloy bar, the two support members 32 can be rotated into the corresponding first assembly slot 11 along with the corresponding rotating arm 31, so as to avoid the support mechanism 3 interfering with the installation between the first mold 1 and the extrusion machinery.

[0047] It should be emphasized that when the rotating arm 31 rotates into the first assembly slot 11, since the round rod 33 is threadedly connected to the first round hole 111, the round rod 33 will move axially to the side opposite to the splicing surface of the first mold 1, and at the same time rotate axially in the opposite direction. The round rod 33 will then automatically exit the second round hole 21, so that the first mold 1 and the second mold 2 can be separated from each other.

[0048] In this embodiment, the first mold 1 has four bolt mounting holes 13 at its end away from the mating surface. These bolt mounting holes 13 are used to mount bolts for installation with the extrusion machinery. Two of the four bolt mounting holes 13 are respectively connected to two first mounting slots 11. After the first mold 1 is mounted on the extrusion machinery with bolts, the bolts mounted in the bolt mounting holes 13 can extend into the first mounting slots 11. Thus, when the rotating arm 31 rotates into the corresponding first mounting slot 11, if the rotating arm 31 wants to rotate out of the first mounting slot 11, it will abut against the bolts extending into the first mounting slot 11. This restricts the rotating arm 31 from rotating out of the first mounting slot 11, thereby preventing the rotating arm 31 from rotating out of the first mounting slot 11 after the first mold 1 is installed with the extrusion machinery, thus improving safety.

[0049] In addition, in this embodiment, the support mechanism 3 also includes an elastic element 34 disposed on the side of the rotating arm 31 away from the round rod 33 for pushing the rotating arm 31 toward the splicing surface of the first mold 1. In this embodiment, the elastic element 34 is a helical spring.

[0050] Under its own elastic force, the elastic element 34 pushes the rotating arm 31 towards the mating surface of the first mold 1. If the first mold 1 is installed with the extrusion machinery, this elastic force will force the rotating arm 31 to rotate until it abuts against the bolt. This prevents the rotating arm 31 from wobbling freely within the first mold 1, ensuring the stability of the first mold 1 with the extrusion machinery. After the first mold 1 is removed from the extrusion machinery, the corresponding bolt will exit the first mounting slot 11. Thus, the restriction on the outward rotation of the rotating arm 31 will be lifted, and the rotating arm 31 will automatically rotate out of the first mounting slot 11 under the elastic force of the elastic element 34. It is worth mentioning that the first mold 1 can be disassembled while the second mold 2 is still mated with the first mold 1. In this way, when the rotating arm 31 automatically rotates out, the round rod 33 will automatically screw into the corresponding second round hole 21. This eliminates the need for operators to manually rotate the rotating arm 31 out, reducing the number of steps required for convenient use.

[0051] To facilitate the assembly and disassembly of the round rod 33 and the rotating arm 31 from the first mold 1, in this embodiment, the connection between the round rod 33 and the rotating arm 31 is a detachable connection. Specifically, the rotating arm 31 has a third round hole 311 for inserting the round rod 33 on its side. The third round hole 311 is a threaded hole. The rotating arm 31 has a fourth round hole 312 on the side away from the third round hole 311. The end of the round rod 33 that is inserted into the third round hole 311 has a fifth round hole 313. The fifth round hole 313 is a threaded hole. A fastening bolt 314 threaded into the fifth round hole 313 is inserted into the third round hole 311.

[0052] Thus, when installing the round rod 33 and the rotating arm 31 to the first mold 1, the rotating arm 31 can be inserted into the first mounting slot 11 first, and the third round hole 311 can be aligned with the first round hole 111. Then, the round rod 33 can be screwed in from the end of the first round hole 111 away from the first mounting slot 11. After the round rod 33 passes through the first round hole 111 and is screwed into the third round hole 311, the fifth round hole 313 will be aligned with the fourth round hole 312. At this time, the fastening bolt 314 can be inserted from the fourth round hole 312 and then tightened with the fifth round hole 313. In this way, the round rod 33 is fixed to the rotating arm 31, and the installation of both to the first mold 1 is also completed. The operation of removing the round rod 33 and the rotating arm 31 from the first mold 1 is the same as the above operation, and will not be described again here.

[0053] To facilitate the tightening of the fastening bolts 314 during the assembly and disassembly of the round rod 33 and the rotating arm 31 in the first mold 1, this embodiment also includes the following configuration: Specifically, two second mounting grooves 12 are provided at the end of the first mold 1 away from the mating surface. These two second mounting grooves 12 are respectively connected to two first assembly grooves 11, and each of the two second mounting grooves 12 corresponds to a position of one of the two fastening bolts 314. During the assembly and disassembly process, a socket wrench can be inserted from the second mounting groove 12 into the first assembly groove 11 to tighten the fastening bolts 314, thereby facilitating the assembly and disassembly of the round rod 33 and the rotating arm 31 on the first mold 1.

[0054] Furthermore, to facilitate the assembly and disassembly of the elastic element 34, this embodiment incorporates the following design: Specifically, both second mounting slots 12 are threadedly connected to sealing blocks 121. The ends of both elastic elements 34 furthest from the mating surface of the first mold 1 extend into their respective second mounting slots 12 and abut against the corresponding sealing blocks 121. When installing the elastic element 34, the sealing blocks 121 are unscrewed from the second mounting slots 12, and then the elastic element 34 is inserted into the second mounting slots 12. After entering the second mounting slots 12, the elastic element 34 abuts against the rotating arm 31. Finally, the sealing blocks 121 are screwed back into the second mounting slots 12, thus completing the installation of the elastic element 34. The removal of the elastic element 34 is similar to the installation operation and will not be described further here.

[0055] In summary, the present invention discloses a high-precision aluminum profile extrusion die for new energy power batteries. When the two rotating arms 31 of the first die of the extrusion die rotate out, the support members 32 on the rotating arms 31 can abut against the angle steel 41 on the die placement frame 4, so that the entire extrusion die can be rolled on the angle steel 41 by the two support members 3. This reduces the difficulty of picking up or placing the extrusion die and improves work efficiency to a certain extent.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
