Technical Field
[0001] This invention relates to the field of die casting technology, specifically to a die casting device for an anti-bubbling aluminum alloy bracket. Background Technology
[0002] Aluminum alloy brackets, with their advantages of being lightweight, durable, and rust-free, are widely used in daily life. The semi-solid molding and pressing process used in the production of aluminum alloy brackets can greatly improve production efficiency, resulting in brackets with high qualification rates, stable performance, and good consistency. Currently, aluminum alloy brackets are produced using die-casting equipment.
[0003] Chinese patent CN215356119U provides an aluminum alloy bracket die-casting molding device, including a frame, an upper mold, a lower mold, and a driving component. The lower mold is fixed on the frame, and the upper mold is located directly above the lower mold. The driving component moves the upper mold closer to the lower mold. The upper mold includes a base plate, a fixing component, and several forming plates. Each forming plate has a forming cavity, and each forming cavity increases in size according to the stacking order. The several forming plates are mounted on the upper mold by the fixing component. The upper mold and the lower mold have the same structure.
[0004] The aforementioned patent enables the rapid die casting of different aluminum alloy brackets by installing a molding plate. However, porosity can occur during the die casting process without adequate preventative measures. Porosity in the casting can lead to bubbling during subsequent processing, which is not only unsightly but also affects the quality of the casting. Therefore, it is necessary to reduce the generation of porosity in the casting during the die casting process. Summary of the Invention

Detailed Implementation
[0043] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0044] See Figures 1 to 6 As shown, an anti-bubbling aluminum alloy bracket die-casting molding device includes an upper base 2 and a lower base 1. A hydraulic cylinder 22 is installed at the upper end of the upper base 2, and an upper mold 21 is installed inside the upper base 2. A lower mold 11 is installed inside the lower base 1, and a feed inlet 111 is provided on the side of the lower mold 11. The device also includes several feeding components 3, each feeding component 3 including a pusher pipe 31 and a movable seat 32. The pusher pipe 31 is located at the upper end of the movable seat 32. 1. It can be placed in the feed inlet 111. The movable seat 32 is provided with a pusher cylinder 321. The output end of the pusher cylinder 321 is provided with a pusher plate 3211. The pusher plate 3211 is provided in the feed pipe 311. The lower end of the movable seat 32 is provided with a moving component 33. The moving component 33 can drive the movable seat 32 to move towards the lower base 1. The lower end of the moving component 33 is also provided with a roller 34 and a guide rail 36. The roller 34 is rolled on the guide rail 36.
[0045] One reason for porosity during die casting is that when the molten metal solidifies, the volume shrinks or the solidified area does not receive replenishment of molten metal, thus creating porosity. Therefore, it is necessary to replenish the molten metal at this point to ensure effective solidification. The feed inlet 111 may be different for different molds.
[0046] In general, the upper mold 21 and lower mold 11 can be replaced. After the upper mold 21 and lower mold 11 are installed, the feeding components 3 are moved. According to the feeding port 111 on the lower mold 11, the same number of feeding components 3 are selected. The position of the feeding components 3 is adjusted by the rolling of the roller 34 on the guide rail 36. When it moves to the appropriate position, the moving component 33 is driven. The moving component 33 pushes the moving seat 32 to move. The push tube 31 on the moving seat 32 moves towards the side of the feeding port 111 until the push tube 31 moves towards the side of the feeding port 111. Entering the interior of the lower mold 11, the upper end of the pusher tube 31 is provided with a feed tube 311. After the pusher tube 31 is installed, the hydraulic cylinder 22 moves the upper mold 21 to abut against the lower mold 11, and discharges the material from the feed tube 311. The pusher cylinder 321 pushes the molten metal into the mold through the pusher plate 3211. If the model is large or complex and some places need to be replenished with liquid, a feed port 111 is also set here. Liquid is replenished by adding molten metal into the pusher tube 31 to reduce the generation of air holes. After the die casting is completed, the hydraulic cylinder 22 returns to its original position, the product is removed, and the die casting is completed.
[0047] The roller 34 is provided with a groove 341, and the roller 34 is set on the guide rail 36 through the groove 341. When the pusher cylinder 321 moves, the lateral force on the feeding component 3 is limited by the roller 34 and the guide rail 36, and the feeding component 3 remains stable. One end of the guide rail 36 is provided with an inlet and outlet for the feeding component 3.
[0048] By setting multiple feeding components 3, with rollers 34 and moving components 33 at the lower end of each feeding component 3, when facing a lower mold 11 with multiple feed ports 111, the multiple feeding components 3 are moved by the rollers 34, and the multiple push tubes 31 and feed ports 111 are connected by the moving components 33. This ensures that liquid can be replenished during die casting, reduces the generation of air holes, and allows for quick setting of the feeding end when facing different lower molds 11 by moving the feeding components 3, thus improving production efficiency.
[0049] See Figures 4 to 6 As shown, the moving component 33 includes a drive motor 331 and a threaded rod 332;
[0050] The lower end of the movable seat 32 is provided with a movable block 322, the movable block 322 is provided with a threaded hole, and a support seat 35 is also provided between the movable component 33 and the roller 34.
[0051] The drive motor 331 is mounted on the upper end of the support base 35, and the output end of the drive motor 331 is provided with a first bevel gear 3311;
[0052] The threaded rod 332 is disposed in the threaded hole, and a second bevel gear 3321 is disposed on the threaded rod 332, and the second bevel gear 3321 and the first bevel gear 3311 are meshed together.
[0053] The lower end of the movable block 322 is provided with a limit block 3221, and the support base 35 is provided with a limit groove 352 that cooperates with the limit block 3221. The limit groove 352 does not penetrate the support base 35.
[0054] When the movable seat 32 needs to be moved, the drive motor 331 is activated, and the drive motor 331 starts to rotate. The rotation of the drive motor 331 drives the first bevel gear 3311 to rotate, which causes the second bevel gear 3321 and the threaded rod 332 to rotate. The rotation of the threaded rod 332 drives the movable block 322 to move. Since the lower end of the movable block 322 is equipped with a limit block 3221, the movable block 322 can only move in a straight line. As a result, the movable seat 32 starts to move away from or closer to the lower mold 11. The limit groove 352 is not connected to prevent the movable seat 32 from falling out of the support seat 35.
[0055] See Figure 4 , Figure 5 and Figure 7As shown, two movable plates 323 are mirror-arranged at the lower end of the movable seat 32 along the direction of movement of the movable seat 32. The support seat 35 is provided with a movable groove 351 that cooperates with the movable plates 323. A ball bearing 3511 is provided in the movable groove 351. A first handwheel 333 is provided at the end of the threaded rod 332 away from the movable block 322. A locking rod 3331 is provided on the first handwheel 333.
[0056] When the drive motor 331 is damaged, or when the moving seat 32 needs to be fine-tuned, the first handwheel 333 is rotated. The rotation of the first handwheel 333 drives the threaded rod 332 to rotate, thereby causing the moving seat 32 to move. After the movement is completed, the first handwheel 333 is fixed by rotating the locking rod 3331 to prevent the first handwheel 333 from continuing to rotate, thus ensuring the stability of the push tube 31 installation.
[0057] The movable plate 323 is set in the movable groove 351, and the movable groove 351 is provided with a ball bearing 3511. When the movable seat 32 moves, the movable plate 323 moves in the movable groove 351. The ball bearing 3511 reduces the moving friction of the movable plate 323, so the movement of the movable seat 32 is more effortless, and the rotation of the first handwheel 333 is also easier.
[0058] See Figure 3 , Figure 4 and Figure 8 As shown, guide plates 113 are provided on both vertical sides of the outer end of the feed port 111. A guide slope 1131 is provided on the side of the guide plate 113 away from the lower mold 11. A reinforcing rod 1132 is provided on the side of the guide slope 1131 facing the lower mold 11. A guide groove 1133 is provided on the guide plate 113. A limit plate 312 is provided on the outer side of the push tube 31 facing the front half of the lower mold 11. The limit plate 312 can move within the guide groove 1133.
[0059] When the pusher tube 31 moves toward the feed inlet 111, it first contacts the guide slope 1131 of the guide plate 113. Under the guidance of the guide slope 1131, the pusher tube moves steadily toward the feed inlet 111. The feeding assembly 3 is finely adjusted under the thrust of the guide slope 1131. When the pusher tube 31 moves, the limiting plate 312 also moves in the guide groove 1133. When the limiting plate 312 abuts against the outer side of the lower mold 11, the pusher tube 31 stops moving. The pusher plate 3211 completes the installation at the feed inlet 111. The reinforcing rod 1132 ensures that the guide slope 1131 will not be easily damaged, thus ensuring the stability of the installation.
[0060] By setting a guide plate 113, which has a guide slope 1131 for guiding the push tube 31, the push tube 31 on the feeding assembly 3 can stably enter the feed port 111, and the limiting plate 312 ensures that the push tube 31 can be stably set at the feed port 111, and will not enter the lower mold 11 too deeply or too shallowly.
[0061] See Figure 4 and Figure 9 As shown, the device also includes a locking assembly 37, which includes a rotating rod 372, a telescopic rod 373, a locking block 374, and a second handwheel 371.
[0062] The rotating rod 372 is located in the middle section of the support base 35, and two worm gears 3721 are sleeved on the rotating rod 372;
[0063] The telescopic rod 373 is configured as two, and each of the telescopic rods 373 is fitted with a worm gear 3731 at its upper end. The worm gear 3731 is meshed with the two worms 3721. The telescopic rod 373 passes through the lower half of the support base 35.
[0064] The locking block 374 is located at the end of the telescopic rod 373 away from the worm gear 3731, and an anti-slip disc 3741 is provided at the end of the locking block 374 away from the telescopic rod 373.
[0065] The second handwheel 371 is located at one end of the rotating rod 372.
[0066] A limiting box 3732 is also provided on the outer side of the worm gear 3731. A groove is provided on the side of the telescopic rod 373, and a protrusion that matches the groove is provided on the support base 35. After the push tube 31 is installed, the second handwheel 371 is rotated. The rotation of the second handwheel 371 drives the worm gear 3721 to rotate, which in turn drives the worm gear 3731 to rotate. Since the limiting box 3732 is provided on the outer side of the worm gear 3731, the worm gear 3731 can only rotate. The worm gear 3731 has a threaded mounting hole 1121, and the telescopic rod 373 also has a threaded mounting hole. This allows the worm gear 3731 and the telescopic rod 373 to rotate relative to each other. Under the constraint of the groove and the protrusion, the telescopic rod 373 begins to move downward until the anti-slip disc 3741 contacts the ground. Under the pressure and the action of the anti-slip disc 3741, the roller 34 will no longer slide along the guide rail 36, making the feeding assembly 3 more stable and ensuring that the work can be carried out effectively.
[0067] See Figure 3As shown, the lower mold 11 has several mounting plates 112 on its outer side, and several mounting holes 1121 on the mounting plates 112. Bolts are installed in the mounting holes 1121. The mounting plates 112 also have lifting holes 1122. The lower base 1 has a clearance groove 12 at one end facing the mounting plate 112. The clearance groove 12 is located at the lower end of the lifting hole 1122.
[0068] The lower mold 11 is fixedly connected to the lower base 1 by bolts. When the lower mold 11 needs to be installed, the lower mold 11 is first placed in the lower base 1, and then the bolts are installed through the mounting holes 1121, so that the lower mold 11 is installed on the lower base 1, which is simple and quick.
[0069] When disassembly is required, the bolts in the mounting hole 1121 are removed, thereby eliminating the fixing of the lower mold 11 and the lower base 1. Then, the lower mold 11 can be directly lifted for replacement through the clearance groove 12. When the weight of the lower mold 11 is heavy, a rope is installed in the lifting hole 1122, and then it is lifted mechanically for replacement, which is simple and quick.
[0070] The upper mold 21 is provided with the same mounting plate 112 as the lower mold 11, and the upper base 2 is provided with the same clearance groove 12 as the lower base 1. The installation of the upper mold 21 is similar to that of the lower mold 11.
[0071] See Figure 10 As shown, the upper base 2 is provided with several limiting rods 23 at one end facing the lower base 1, and the lower base 1 is provided with several limiting holes 13. The limiting rods 23 can move within the limiting rods 23. The bottom end of the limiting hole 13 is provided with a buffer spring 131, which can abut against the limiting rods 23.
[0072] When the hydraulic cylinder 22 drives the upper base 2 to move toward the lower base 1, the upper base 2 can move stably under the action of the limiting rod 23 and the limiting hole 13, without rotation or deviation. Thus, the upper mold 21 can stably abut against the lower mold 11. Before the upper mold 21 and the lower mold 11 abut, the limiting rod 23 and the buffer spring 131 contact first, thereby reducing the impact of the upper mold 21 on the lower mold 11, protecting the mold, and increasing the service life of the device.
[0073] See Figure 1 and Figure 11 As shown, the device also includes a vacuum assembly 4, which includes a first outlet pipe 41, a filter box 42, and a second outlet pipe 43.
[0074] The first vent pipe 41 is located at the upper end of the upper base 2, and the first vent pipe 41 is connected to the upper mold 21.
[0075] The filter box 42 is located at the end of the first air outlet pipe 41 that is away from the upper mold 21;
[0076] One end of the second air outlet pipe 43 is connected to the filter box 42, and the end of the second air outlet pipe 43 away from the filter box 42 is connected to a vacuum pump.
[0077] Another reason for porosity is that there is too much gas in the mold, which cannot be discharged during die casting, thus causing porosity in the die casting. So when the material is about to be fed, the upper mold 21 and the lower mold 11 are already in contact. The vacuum pump is started and the vacuum pump starts to extract air through the first air outlet pipe 41 and the second air outlet pipe 43. The gas in the mold is extracted, so that there will be no gas in the mold during die casting, which will cause porosity.
[0078] Due to continuous use, impurities or mold release agents in the mold may affect the vacuum pump. Therefore, a filter box 42 is provided to filter out the impurities and protect the vacuum pump. Since the filter box 42 is located at the upper end of the upper base 2, the second air outlet pipe 43 is made into a flexible hose so as not to affect the movement of the upper base 2.
[0079] See Figure 11 and Figure 12 As shown, the upper end of the filter box 42 is provided with several through holes 422, and a pull plate 421 is provided in the through holes 422. A filter plate 423 is provided in the middle of the pull plate 421. A sealing gasket 4212 is provided at one end of the pull plate 421 near the through holes 422. A handle 4211 is provided at the outer end of the pull plate 421. A fixing rod 424 is also provided at the upper end of the filter box 422. A rotating plate 425 is rotatably provided on the fixing rod 424. The lower end of the rotating plate 425 and the upper end of the pull plate 421 can abut against each other.
[0080] After the filter box 42 has been used for a period of time, the filter plate 423 needs to be replaced. Rotate the rotating plate 425 so that the pull plate 421 can be pulled out directly through the handle 4211. The middle of the pull plate 421 is the filter plate 423. If there are too many impurities on the filter plate 423, the filter plate 423 needs to be replaced. After the replacement is completed, the pull plate 421 is placed in the filter box 42 through the through hole 422. Rotate the rotating plate 425 again. The rotating plate 425 restricts the pull plate 421 to prevent it from falling off.
[0081] The sealing gasket 4212 ensures the airtightness of the filter box 42, thereby ensuring the suction efficiency of the vacuum pump. The fixing rod 424 can restrict the up and down movement of the rotating plate 425, ensuring that the rotating plate 425 restricts the pull plate 421.
[0082] See Figure 13As shown, the device also includes a heating component 5, which is disposed at the lower end of the lower base 1. The heating component 5 includes multiple heating units and can heat the lower mold 11.
[0083] Different cooling times of molten metal in different areas can also lead to porosity. Therefore, the mold is usually preheated by setting multiple heating components 5 to ensure preheating of the mold. In the die casting process, by controlling each heating unit, the heating time of some areas that cool faster is longer than that of areas that cool slower, so that the cooling time of each area is consistent and will not cause porosity due to some areas cooling too fast.
