Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5As shown, a high-precision extrusion press for extruding aluminum profiles for automotive seats includes a housing 1, an upper die 101, and a lower die 102. Cooling components are fixedly connected to both sides of the housing 1. Each cooling component includes a mounting block 2. Two connecting plates 201 are bolted to one side of the mounting block 2. Multiple sliding blocks 202 are slidably connected to the inner cavities of the two connecting plates 201. A through hole 203 is provided on one side of the mounting block 2. A nozzle 204 is slidably connected to the inner cavity of the sliding block 202. A limiting plate 205 is fixedly connected to the surface of the nozzle 204. A first spring 206 is fitted onto the opposite surfaces of the sliding block 202 and the limiting plate 205. The nozzle 204 extends through the through hole 203 into the inner cavity of the mounting block 2. Multiple air inlets 207 are provided on the surface of the nozzle 204. Multiple sealing components are provided in the inner cavity of the mounting block 2. Each sealing component includes two guide pillars 3. Sealing plates 301 are slidably connected to the surfaces of the two guide pillars 3. The sealing plates 301 and the guide pillars... The opposite side of the 3 is fitted with a second spring 302. The sealing plate 301 is positioned corresponding to the through hole 203. Both connecting plates 201 are L-shaped. The sliding block 202 is I-shaped. The front and rear surfaces of the two connecting plates 201 are bolted together with a limit plate 4. A threaded hole is opened on the other side of the mounting block 2. The inner cavity of the threaded hole is threaded with an air pipe connector 5. Both sides of the housing 1 are provided with reserved holes 501. The position of the reserved holes 501 corresponds to the position of the air pipe connector 5. A cylinder 6 is fixedly connected to the top of the housing 1. One end of the telescopic rod of the cylinder 6 is bolted to the top of the upper mold 101. Buffer columns 7 are fixedly connected to the four corners of the bottom of the upper mold 101. Buffer holes 701 are opened at the four corners of the top of the lower mold 102. The position of the buffer holes 701 corresponds to the position of the buffer columns 7. The outer diameter of the nozzle 204 is equal to the inner diameter of the through hole 203. The outer diameter of the sealing plate 301 is greater than the inner diameter of the through hole 203.

[0025] Before using the device, one end of the external air source pipe should be accurately connected to the pipe connector 5 through the reserved hole 501. During the connection process, it is necessary to ensure that the pipe and the pipe connector 5 fit tightly to avoid air leakage.

[0026] Next, prepare the aluminum profile to be processed and slowly place it on top of the lower mold 102. After placement, gently press the aluminum profile to check whether it is in full contact with the lower mold 102 and whether there is any shaking or tilting.

[0027] After confirming that the aluminum profile is properly placed, cylinder 6 is started. After cylinder 6 is started, its telescopic rod will drive the upper mold 101 to move downward according to the set speed and stroke. When the aluminum profile comes into contact with the upper mold 101, it will feel a certain pressure. At this time, cylinder 6 will continue to apply pressure, so that the upper mold 101 will extrude and form the aluminum profile.

[0028] At the moment the upper mold 101 and the lower mold 102 close, the buffer pillar 7 enters the inner cavity of the buffer hole 701. The head of the buffer pillar 7 is designed with a smooth arc shape so that it can be smoothly inserted into the buffer hole 701. The inner wall of the buffer hole 701 is made of damping sheet. When the buffer pillar 7 enters, it will rub against the damping sheet, thereby effectively reducing the buffering force during mold closing. This buffering effect can reduce the impact force between molds, extend the service life of the mold, and improve the forming quality of aluminum profiles, avoiding defects on the surface of aluminum profiles due to excessive impact force.

[0029] After the stamping is completed, the telescopic rod of cylinder 6 will drive the upper mold 101 to move upward and return to the initial position. After cylinder 6 is reset, the external air source is started and the air source valve is opened.

[0030] Gas enters the inner cavity of mounting block 2 at a stable pressure through air pipe and air pipe connector 5. The gas entering the inner cavity of mounting block 2 will enter the inner cavity of nozzle 204 through air inlet 207, and spray the gas out in a cone shape, so that the gas can evenly cover the surface of the formed aluminum profile and effectively cool it.

[0031] When the position of the nozzle 204 needs to be adjusted, hold the nozzle 204 with your hand and apply a uniform pulling force so that the surface of the nozzle 204 is separated from the inner cavity of the mounting block 2 through the through hole 203. When the nozzle 204 moves, it will drive the limiting plate 205 to move. The limiting plate 205 will gradually compress the first spring 206. When the surface of the nozzle 204 is completely separated from the inner cavity of the mounting block 2, since the sealing plate 301 is no longer squeezed by one end of the nozzle 204, under the action of the second spring 302, the sealing plate 301 will move on the surface of the two guide posts 3. The sealing plate 301 will quickly seal the through hole 203 to prevent gas from leaking through the through hole 203.

[0032] At this point, pushing the sliding block 202 will cause the nozzle 204 to move along a preset track. When pushing the sliding block 202, and with one end of the nozzle 204 aligned with the through hole 203, releasing the nozzle 204 will cause it to automatically move upward under the action of the first spring 206. The first spring 206 will quickly release its elastic potential energy, pushing the nozzle 204 upward. The nozzle 204 will then press against the sealing plate 301 through the through hole 203, causing the sealing plate 301 to move upward and press against the second spring 302. This continues until the air inlet 207 on the surface of the nozzle 204 is inside the cavity of the mounting block 2, at which point the nozzle 204 returns to its normal working state.

[0033] Using the above method, when it is necessary to add or remove sealing components, first use appropriate tools to remove the two bolted limit plates 4. After disassembly, add or remove sealing components according to actual needs. If a sealing component needs to be added, ensure that the new sealing component is consistent with the original sealing component in specifications and that the installation direction is correct. After installation, reinstall the limit plates 4 and tighten the bolts with tools to ensure that the limit plates 4 are securely installed.

[0034] When it is necessary to replace the nozzle 204, first remove the sealing assembly, then slowly pull the nozzle 204 out of the inner cavity of the sliding block 202, and then insert the nozzle 204 to be replaced back into the inner cavity of the sliding block 202, ensuring that the nozzle 204 and the sliding block 202 fit tightly. Finally, reconnect it to the two connecting plates 201, and use bolts or clips to fix the connecting plates 201 in place, ensuring that the connection is firm.
