Description
Technical Field
[0001] This invention relates to the field of die casting technology, and more specifically, to an aluminum alloy pot body die casting machine. Background Technology
[0002] Aluminum alloy pot body die casting machine is a device used to rapidly fill a mold cavity with molten aluminum alloy under high pressure and form an aluminum alloy pot body blank. It belongs to the basic process equipment for blank forming in the manufacturing of aluminum alloy cookware. This die casting machine mainly realizes the filling and solidification of molten metal through mold cooling and shaping, and finally obtains an aluminum alloy pot body casting with a shape and size close to the finished product, providing pot body blanks for subsequent machining and surface treatment.
[0003] In the die-casting process, molten aluminum is scooped from the holding furnace using a ladle and then fed into the die-casting machine's pressure chamber. After being removed from the furnace, the molten aluminum alloy surface is exposed to air, causing rapid oxidation and the formation of an oxide scale. This oxide scale is scooped into the ladle along with the molten aluminum and carried into the pressure chamber during subsequent feeding. During the die-casting filling stage, the oxide scale enters the mold cavity with the molten aluminum, ultimately remaining inside or on the surface of the casting, forming inclusions. These defects result in surface quality flaws such as black spots and bumps on the casting's appearance, while also reducing the internal density of the casting and weakening the finished product's mechanical properties and service life. Summary of the Invention
[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide an aluminum alloy pot body die casting machine to solve the problem that during the aluminum alloy pot body die casting process, the oxide scale on the liquid surface is carried into the mold cavity, resulting in slag inclusion defects in the pot body casting, which affects the appearance quality and internal density of the product.

[0009] Furthermore, a first spring is fixedly connected to the bottom end of the first connecting post, and the bottom end of the first spring is fixedly connected to the inner bottom end of the blocking post.
[0010] Furthermore, it also includes a demolding auxiliary mechanism, which is disposed inside the upper mold. The demolding auxiliary mechanism includes multiple ventilation chambers opened inside the upper mold, and each of the multiple ventilation chambers is provided with a mold supplement block. Multiple ventilation slots are opened inside the ventilation chambers. A movable rod is fixedly connected to the surface of the mold supplement block. A support cylinder is fixedly connected to the inside of the ventilation chamber. The movable rod is slidably inserted into the inside of the support cylinder. A pull rope is fixedly connected to the surface of the movable rod. A third spring is fixedly connected to one end of the movable rod located inside the support cylinder.
[0011] Furthermore, the ventilation cavity is rotatably connected to a bent support wheel.
[0012] Furthermore, the top of the upper mold is provided with a plurality of ventilation holes that are respectively connected to the plurality of ventilation chambers.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) This scheme pours molten aluminum liquid into the inclined side of the injection hopper and controls the flow thickness. With the help of the diversion plate, the aluminum liquid containing oxide scale in the upper part is separated from the pure aluminum liquid in the lower part. The aluminum liquid flows into the injection cylinder through the lower part of the injection pipe to participate in die casting, while the aluminum liquid with a higher degree of oxidation is discharged from the discharge pipe. This effectively reduces the oxide scale content entering the mold cavity and improves the quality of the die-cast product.
[0016] (2) This scheme uses the cooperation between the first spring and the support shaft in the limiting groove to store energy during the downward movement of the pressure block. When the support shaft comes out of the groove, it releases energy instantly, impacting the molten aluminum liquid. During the pressure filling process, it effectively removes air bubbles, reduces internal cavity defects in the casting, and further improves the quality of the die-cast product.
[0017] (3) This solution uses the rotating screw to drive the upper support block to squeeze the support block, so that the rotating ring rotates and pulls the movable rod and the mold supplement block to move, connecting the ventilation cavity with the outside, allowing air to enter and eliminate the negative pressure between the aluminum alloy pot body and the upper mold, making it easier for the casting to be demolded smoothly, and preventing difficulties in removing the casting or damage to the casting caused by the adsorption force.
[0018] (4) After demolding, the screw is rotated in the opposite direction to release the pressure on the support block. The elastic force of the third spring is used to push the movable rod to extend, so that the mold supplement block can automatically return to the assembly state with the upper mold. It can be put into the next die casting operation without manual reset, thus improving the efficiency of continuous production. Attached Figure Description

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see Figures 1-5An aluminum alloy pot body die-casting machine includes a die-casting table 1 and an injection mechanism. The injection mechanism is disposed on the upper surface of the die-casting table 1. The injection mechanism includes a lower mold 201 fixedly connected to the upper surface of the die-casting table 1. A hydraulic cylinder 203 is fixedly connected to the upper surface of the die-casting table 1. An upper mold 202 adapted to the lower mold 201 is fixedly connected to the top of the hydraulic cylinder 203. An injection channel 205 is provided through the middle of the upper mold 202. An injection cylinder 204 communicating with the injection channel 205 is fixedly connected to the upper surface of the upper mold 202. An injection pipe 206 is connected to the side of the injection cylinder 204. An injection hopper 207 is connected to the top of the injection pipe 206. A partition plate 209 is fixedly connected inside the injection pipe 206. A diverter plate 208 is fixedly connected to the top of the partition plate 209. The diverter plate 208 is fixedly connected to the inner wall of the injection hopper 207.
[0023] The partition plate 209 divides the injection pipe 206 into upper and lower spaces. The lower end of the injection pipe 206 is provided with a discharge pipe 210 that communicates with the upper space of the injection pipe 206. The upper end of the injection cylinder 204 is fixedly connected to a support plate 217. The upper surface of the support plate 217 is fixedly connected to a hydraulic rod 212. The top end of the hydraulic rod 212 is fixedly connected to a cross-shaped frame 224. The lower surface of each arm of the cross-shaped frame 224 is fixedly connected to a first connecting post 213. A blocking post 215 is slidably sleeved on the surface of the first connecting post 213. The injection cylinder 204 is provided with a pressure block 211. The edge of the pressure block 211 is made of flexible graphite to increase the sealing effect. The pressure block 211 and the injection cylinder 204 form a piston assembly. The bottom end of the blocking post 215 is fixedly connected to the upper surface of the pressure block 211.
[0024] The upper end of the injection cylinder 204 is fixedly connected to a second connecting post 218. A support plate 223 is fixedly connected to the surface of the second connecting post 218. A second spring 222 is fixedly connected to the side of the support plate 223 away from the second connecting post 218. A plurality of limiting grooves 216 are formed on the surface of the blocking post 215. A connecting frame 220 is fixedly connected to the end of the second spring 222 near the blocking post 215. A support shaft 219 adapted to the limiting grooves 216 is rotatably connected to the surface of the connecting frame 220. A plurality of first guide rods 221 are fixedly connected to the surface of the connecting frame 220. The plurality of first guide rods 221 are inserted into the interior of the support plate 223. A first spring 214 is fixedly connected to the bottom end of the first connecting post 213. The bottom end of the first spring 214 is fixedly connected to the bottom end of the interior of the blocking post 215.
[0025] By adopting the above technical solution, during die casting, the hydraulic cylinder 203 drives the upper mold 202 downward, causing the upper mold 202 to close with the lower mold 201. Then, molten aluminum is poured into the inclined side of the injection hopper 207. During the pouring process, the thickness of the molten aluminum should be maintained slightly higher than the height of the partition plate 209 and the bottom of the injection pipe 206. This allows the diverter plate 208 to separate the oxidized portion of the molten aluminum as it flows into the injection pipe 206, reducing the oxide scale content in the lower part of the injection pipe 206 and thus minimizing the impact of oxide scale on the quality of the subsequent die-cast product. The molten aluminum in the lower part of the injection pipe 206 then flows into the injection cylinder 204, while the molten aluminum with a higher degree of oxidation in the upper part of the injection pipe 206 can be discharged through the discharge pipe 210.
[0026] After the molten aluminum flows into the injection pipe 206, it continues to flow through the injection channel 205 to the space between the upper mold 202 and the lower mold 201. Then, the hydraulic rod 212 pulls down the cross-shaped frame 224 and the first connecting column 213, thereby driving the pressure block 211 to move downward and apply pressure to the molten aluminum, so that some of the molten aluminum that did not flow normally into the space between the upper mold 202 and the lower mold 201 flows into the space between the upper mold 202 and the lower mold 201.
[0027] During the downward movement of the pressure block 211, the second spring 222 pushes the support shaft 219 into the restrictive groove 216, thus increasing the resistance to the downward movement of the pressure block 211 and simultaneously compressing the first spring 214. As the blocking post 215 continues to move downward, the support shaft 219 is gradually pushed outward along the inclined side of the restrictive groove 216, and the second spring 222 is further compressed. At the instant the support shaft 219 completely disengages from the restrictive groove 216, the elastic potential energy stored in the first spring 214 is suddenly released, applying a downward impact force to the pressure block 211, causing the pressure block 211 to impact the molten aluminum. Since the surface of the blocking post 215 has multiple restrictive grooves 216 along the axial direction, as the blocking post 215 continues to descend, the support shaft 219 sequentially enters and disengages from each restrictive groove 216, resulting in multiple continuous impacts. This reduces air bubbles in the molten aluminum during the pressurization process, thereby reducing cavities generated during die casting and further improving the quality of the subsequent die-cast products.
[0028] like Figures 6-8As shown, it also includes a demolding auxiliary mechanism, which is disposed inside the upper mold 202. The demolding auxiliary mechanism includes multiple ventilation chambers 309 formed inside the upper mold 202. Each of the multiple ventilation chambers 309 is provided with a mold supplement block 301. Multiple ventilation slots 304 are formed inside the ventilation chambers 309. A movable rod 303 is fixedly connected to the surface of the mold supplement block 301. A support cylinder 307 is fixedly connected to the inside of the ventilation chamber 309. The movable rod 303 is slidably inserted into the inside of the support cylinder 307. A pull rope 306 is fixedly connected to the surface of the movable rod 303. A third spring 315 is fixedly connected to one end of the support cylinder 307. A bending support wheel 305 is rotatably connected inside the ventilation cavity 309. The top of the upper mold 202 is provided with a plurality of ventilation holes 308 that are respectively connected to the plurality of ventilation cavities 309. The pull rope 306 is inserted through the ventilation holes 308. A plurality of guide frames 310 are fixedly connected to the top of the upper mold 202. A rotating ring 302 is provided between the plurality of guide frames 310. The plurality of guide frames 310 are slidably connected to the surface of the rotating ring 302. The top of the pull rope 306 is fixedly connected to the lower surface of the rotating ring 302.
[0029] The rotating ring 302 has a support block 311 fixedly connected to its surface. The top of the upper mold 202 is rotatably connected to a screw 314. The screw 314 has an upper support block 312 threadedly fitted onto its surface. A second guide rod 313 is inserted into the upper support block 312. The bottom end of the second guide rod 313 is fixedly connected to the top of the upper mold 202. The support block 311 has a right-angled triangle cross-section, and the upper support block 312 has a right-angled trapezoid cross-section. The upper support block 312 is in contact with the inclined surface of the support block 311.
[0030] By adopting the above technical solution, after the die casting is completed and the aluminum alloy pot body is cooled and solidified, the upper support block 312 is moved upward by rotating the screw 314. The upper support block 312 can squeeze the support block 311, causing the support block 311 to drive the rotating ring 302 to rotate, thereby pulling the pull rope 306 and pulling the movable rod 303 and the mold supplement block 301 to move obliquely upward. At this time, the third spring 315 is in a compressed state. During the process of the mold supplement block 301 moving obliquely upward, under normal conditions, the outer surface of the mold supplement block 301 is flush with the cavity surface of the upper mold 202, and its side completely seals the inlet of the venting groove 304, so that the venting cavity 309 is isolated from the outside atmosphere. When the pull rope 306 pulls the movable rod 303, moving the mold replenishment block 301 to the middle of the venting groove 304, the side of the mold replenishment block 301 no longer blocks the entrance of the venting groove 304, exposing the venting groove 304. This allows the venting chamber 309 to communicate with the outside atmosphere of the upper mold 202 through the venting groove 304. Air enters the venting chamber 309 through the venting groove 304, and then enters the gap between the aluminum alloy pot body and the upper mold 202, eliminating the negative pressure between them. This facilitates the demolding of the casting and prevents the aluminum alloy pot body from adhering to the upper mold 202, making it difficult to remove, or causing damage to the aluminum alloy pot body if forcibly removed. After the aluminum alloy pot body is removed, the screw 314 is rotated in the opposite direction to stop pressing the support block 311. The third spring 315 pushes the movable rod 303 to extend from the support cylinder 307, allowing the mold replenishment block 301 to reassemble with the upper mold 202, thus enabling the next die-casting operation.
[0031] Instructions for use: First, the hydraulic cylinder 203 drives the upper mold 202 to move downwards, closing with the lower mold 201; Next, pour the molten aluminum liquid into the inclined side of the hopper 207, keeping the thickness of the molten aluminum liquid slightly higher than the height of the partition plate 209 and the bottom of the injection tube 206; When the molten aluminum flows into the injection pipe 206, the diversion plate 208 separates the upper oxidized part, allowing the molten aluminum with a lower degree of oxidation to flow into the lower part of the space of the injection pipe 206, while the molten aluminum with a higher degree of oxidation is discharged through the discharge pipe 210. Next, the molten aluminum in the lower part of the injection tube 206 passes through the injection channel 205 and flows between the upper mold 202 and the lower mold 201; Hydraulic rod 212 pulls down cross-shaped frame 224 and first connecting column 213, causing pressure block 211 to move downward, applying pressure to molten aluminum liquid, so that molten aluminum liquid that has not flowed normally can enter between molds; Next, as the pressure block 211 moves downward, the second spring 222 pushes the support shaft 219 to engage in the limiting groove 216, increasing the downward resistance and compressing the first spring 214. When the pressure continues to be applied to disengage the support shaft 219 from the limiting groove 216, the pressure of the first spring 214 is released instantaneously, applying a downward impact force to the pressure block 211, causing the pressure block 211 to impact the molten aluminum liquid and reduce bubbles. After the die casting is completed and the aluminum alloy pot body cools and solidifies, the screw 314 is rotated to drive the upper support block 312 to move upward, squeezing the support block 311, causing the support block 311 to drive the rotating ring 302 to rotate and pull the pull rope 306, pulling the movable rod 303 and the mold supplement block 301 to move obliquely upward, and the third spring 315 is in a compressed state. When the mold supplement block 301 moves to the middle of the ventilation groove 304, the ventilation groove 304 connects the ventilation chamber 309 with the outside of the upper mold 202, and air enters to eliminate the negative pressure between the aluminum alloy pot body and the upper mold 202. After removing the aluminum alloy pot body, the screw 314 is rotated in the opposite direction to stop pressing the support block 311. The third spring 315 pushes the movable rod 303 to extend out of the support cylinder 307, so that the mold supplement block 301 is reassembled with the upper mold 202 in preparation for the next die casting.
