[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-Figure 8 As shown: an integrated extrusion die for aluminum profiles for new energy vehicle batteries, including a support base 44, a fixing member 45 is fixedly connected to one side of the support base 44, a cooling component 2 is arranged on one side of the fixing member 45, the cooling component 2 includes an auxiliary member 21, a cooling shell 22 and a built-in bar 223, the auxiliary member 21 and the cooling shell 22 form a cooling cavity, a cooling cavity 211 is connected to a side wall of one side of the cooling cavity, the cooling cavity 211 is opened on one side of the auxiliary member 21, a T-shaped member 212 is fixedly connected to one side of the auxiliary member 21, a horizontal bar 221 is inserted through the bottom of the T-shaped member 212, and one side of the horizontal bar 221 is fixedly connected to the cooling shell 22; A connecting plate 227 is slidably connected inside the cooling shell 22, and an electric push rod 225 is fixedly connected to the top of the connecting plate 227. The top of the electric push rod 225 is fixedly connected to the cooling shell 22, and an ejection block 226 is fixedly connected to the top of the connecting plate 227. The ejection block 226 is slidably connected to the cooling shell 22, and cooling pipes 23 are arranged on both sides of the ejection block 226. One side of the cooling pipe 23 is embedded with the inner wall of the cooling shell 22, and one end of the cooling pipe 23 passes through the side wall of the cooling shell 22, and a limiting groove 228 is provided on one side of the cooling shell 22. A limiting member 222 is inserted in the limiting groove 228, and one side of the limiting member 222 is engaged with the T-shaped member 212. An internal strip 223 is fixedly connected to one side of the inner wall of the cooling shell 22, and a guide roller 224 is rotatably connected to one side of the internal strip 223. The guide roller 224 and the ejection block 226 are spaced apart.

[0023] In this example, the cooling chamber 211 can assist external air to enter the auxiliary component 21, and then enter the cooling chamber through the cooling chamber 211, thereby accelerating the air flow inside the cooling chamber and realizing air cooling of the profile. The horizontal bar 221 can guide the installation of the auxiliary component 21 and the T-shaped component 212 on the top of the cooling shell 22, and the limiter 222 can reinforce the connection between the horizontal bar 221 and the T-shaped component 212, thereby reducing the looseness of the auxiliary component 21 and the cooling shell 22 during use, and facilitating the subsequent rapid disassembly between the auxiliary component 21 and the cooling shell 22, thereby reducing the shielding of the top of the profile by the auxiliary component 21 when the profile is taken out. At the same time, the electric push rod 225 can provide power for the lifting and lowering of the connecting plate 227, and multiple ejection blocks 226 can be connected through the connecting plate 227, so as to realize the synchronous lifting and lowering of multiple ejection blocks 226. The upward movement of the ejection block 226 drives the profile to move up and separate from the cooling cavity, so as to facilitate the rapid removal of the profile from the cooling shell 22. The built-in strip 223 can support one end of the guide roller 224, so as to facilitate the stable rotation of the guide roller 224 inside the cooling shell 22, so as to guide the profile when it is pulled and moved, and reduce the friction between the profile and the inner wall of the cooling shell 22. The blocks 226 are arranged at intervals, so that the ejection block 226 can avoid interfering with the movement of the guide roller 224 when moving upward. One side of the cooling pipe 23 is embedded with the inner wall of the cooling shell 22, and the side of the cooling pipe 23 away from the inner wall of the cooling shell 22 is overlapped with the profile, which can increase the heat dissipation area of ​​the profile surface. The cooling pipe 23 is made of heat-conducting metal material. The water pump can accelerate the flow of water inside the cooling pipe 23, thereby improving the heat absorption effect of the cooling pipe 23 and achieving auxiliary cooling of the profile surface. When used in combination with the cooling chamber 211, the cooling effect on the profile can be improved, thereby achieving rapid heat dissipation on the profile surface.

[0025] In this embodiment, the fixing part 45 can be used to assist in the connection between one side of the support base 44 and the cooling shell 22, and the support base 44 can be used to support the driving motor 41 and the guide seat 43. The driving motor 41 can provide power for the rotation of the screw 4, so that the screw 4 can stably rotate on the side of the fixing part 45. The guide rod 42 can guide the movement of the guide seat 43 to improve the stability of the guide seat 43 during movement. At the same time, the guide seat 43 can be used to support and reinforce the bottom of the pneumatic finger 3 to improve the stability of the pneumatic finger 3 during use. The pneumatic finger 3 can be used to adjust the distance between the two L-shaped jaws 31, so that the L-shaped jaws 31 can be used to clamp the profile. After clamping, the guide seat 43 moves synchronously with the pneumatic finger 3 to pull the profile and move the profile inside the mold assembly 1 and the cooling assembly 2.

[0026] Embodiment 3: According to Figure 1-Figure 5 As shown, a mold assembly 1 is provided on one side of the cooling component 2, and the mold assembly 1 includes a lower mold 11, a mold body 12 and an upper mold 13.

The inner part 121 and the extension part 123 are both inserted through the lower mold 11 and the upper mold 13.

[0027] In this embodiment, the guide block 111 can be used to guide the installation of the upper mold 13 on the top of the lower mold 11, so as to assist the connection between the lower mold 11 and the upper mold 13. The guide hole 112 can assist the connection between the plug-in rod 122 and the lower mold 11 and the upper mold 13, thereby guiding the connection between the mold body 12 and the lower mold 11 and the upper mold 13, reducing the position deviation of the mold body 12 when connected, and thereby ensuring that the built-in component 121 and the extension component 123 are smoothly inserted into the molding cavity surrounded by the lower mold 11 and the mold body 12. The built-in component 121 can reinforce the bottom of the extension component 123. The molding cavity surrounded by the built-in component 121, the extension component 123 and the inner wall of the lower mold 11 and the upper mold 13 can assist the extrusion molding of the aluminum profile. At the same time, the mold body 12 can be disassembled and replaced on one side of the lower mold 11 and the upper mold 13, and the lower mold 11 and the upper mold 13 are also easy to disassemble.

[0028] The method of using the device and the working principle are as follows: first, the upper mold 13 is moved on the top of the lower mold 11, so that the side wall of the guide groove at the bottom of the upper mold 13 overlaps with the guide block 111, and then the organized lower mold 11, the upper mold 13 and the plug-in rod 122 on one side of the mold body 12 are plugged, and the built-in part 121 and the extension part 123 are plugged into the lower mold 11 and the upper mold 13 to realize the overall assembly of the mold assembly 1; the auxiliary part 21 is overlapped on the top of the cooling shell 22, and the T-shaped part 212 is inserted into the cooling shell 22. Connected to the horizontal bar 221, and then install the limiter 222 on one side of the cooling shell 22, so that one side of the limiter 222 is engaged with the side wall of the T-shaped piece 212, and one end of the limiter 222 is inserted into the limiter groove 228, so as to realize the installation of the auxiliary part 21 and the cooling shell 22, and then the lower mold 11 and the upper mold 13 are engaged with the cooling shell 22 and the auxiliary part 21 on the side away from the mold body 12, respectively, and the fixing part 45 is installed on the side of the cooling shell 22 by bolts, and the whole device can be used; When in use, the end of the cooling pipe 23 can be connected to an external water pump and a water tank to accelerate the flow of water inside the cooling pipe 23, and then the raw material of the aluminum profile is sent into the mold assembly 1 from one side of the mold body 12. The raw material can be formed into a target shape after extrusion. The formed profile enters the cooling assembly 2 and contacts the cooling pipes 23 on both sides of the inner wall of the cooling shell 22 to be cooled. A fan can be placed on one side of the cooling chamber 211. The fan accelerates the flow of air, so that the air enters the cooling chamber from the cooling chamber 211 and flows quickly inside the cooling chamber to assist the profile in cooling. The subsequent raw materials push the initial end to move until the initial end moves out of the cooling assembly 2, and the pneumatic fingers 3 are used to drive the two L-shaped clamps 31 to approach each other and clamp one end of the profile, and then the motor 41 is driven to drive the screw 4 to rotate, and the screw 4 Under the action of the thread, the guide seat 43 is driven to move along the support base 44 and the guide rod 42 to pull the profile out, so that the end of the profile is separated from the mold assembly 1 and completely enters the cooling assembly 2, and then the pneumatic fingers 3 and the guide seat 43 stop pulling the profile, remove the limit members 222 on both sides of the cooling shell 22, move the auxiliary member 21 upward, separate the T-shaped member 212 from the cross bar 221, and separate the auxiliary member 21 from the cooling shell 22. The electric push rod 225 is driven to contract by an external controller, and the connecting plate 227 drives the ejection block 226 to move upward. After the ejection block 226 contacts the bottom of the profile, it pushes the profile upward and separates it from the cooling chamber. At this time, the profile can be quickly taken out from the inside of the cooling shell 22. After being taken out, the auxiliary member 21 can be installed on the top of the cooling shell 22 for reset.
