Description

Technical Field

[0001] The invention belongs to the technical field of low-pressure casting, and in particular relates to a low-pressure casting device for an aluminum alloy pipeline. Background Art

[0002] Aluminum alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature resistance, low temperature resistance and corrosion resistance are unmatched by other seamless steel pipes. The inner surface is smooth and the self-oxidation layer is corrosion-resistant; the compressed air pressure loss is small and energy-saving.

[0003] A search of CN117086288B discloses a low-pressure casting device for aluminum alloy pipes and a method of using the same. The shearing machine for steel structure processing combines and splices the casting mold and performs rotation adjustment through the overall structure of the equipment, and can quickly demold the aluminum alloy pipe. A single casting can form multiple aluminum alloy pipes, and the casting efficiency is high.

[0004] When the low-pressure casting device for aluminum alloy pipes is in use, low-pressure casting of the aluminum alloy pipes is achieved through structures such as a pressurized material guiding mechanism, a pressurized box, a cylinder, and a guide rod. However, in actual use, after the casting of the aluminum alloy pipe is completed, the device directly demoulds the pipe after rotating it. The surface of the aluminum alloy pipe is relatively rough after casting, and it cannot be polished during demoulding, which requires subsequent polishing, reducing the working efficiency of the low-pressure casting device.

[0043] Embodiment 3:

[0044] A flow guide mechanism 5 is provided on one side of the bottom plate 1;

[0045] The flow guiding mechanism 5 includes a belt 2 501, a rotating rod 4 502, a half gear 503, a gear 504, and a rotating rod 505. The rotating rod 1 303 is connected to the rotating rod 4 502 through the belt 2 501. The outer wall of the rotating rod 4 502 is connected to the inner wall of the half gear 503. The half gear 503 is meshed with the gear 504. The inner wall of the gear 504 is connected to the outer wall of the rotating rod 505.

Both ends of the rotating rod 505 are connected to the inner side of the fixed plate 4 508 for rotation.

[0046] In this embodiment, there are four guide rollers 507, which are symmetrically distributed on the inner side of the fixing plate 508. The fixing plate 508 is U-shaped, so that the aluminum alloy pipe can be better guided and transported. In addition, the half gear 503 can make the transmission roller 506 move indirectly, so that the aluminum alloy pipe can be moved indirectly and slowly, which is more convenient for the operator to collect and process later.

[0047] Furthermore, the top of the base plate 1 is fixedly connected to the bottom of the support plate 2, one end of the fixed plate 301 is interconnected with one side of the base plate 1, the bottom of the placement plate 311 is fixedly connected to the top of the fixed plate 301, the bottom of the connecting plate 2 317 and the fixed plate 2 322 are fixedly connected to the top of the fixed plate 1 301, and one side of the support plate 2 is interconnected with one end of the motor 2 409.

[0048] The implementation principle of the low-pressure casting device for an aluminum alloy pipe in the present embodiment is as follows: when it is necessary to cast the aluminum alloy pipe, the operator injects the molten metal into the mold 406 through the injection assembly 401 for casting. When the casting is completed, the aluminum alloy pipe will move along the guide tube 319. At this time, the motor 302 is started to drive the rotating rod 303 to rotate, and the grinding roller 305 is driven to rotate by the rotation of the rotating rod 303. The aluminum alloy pipe is guided and moved through the guide tube 319 and moves from the grinding roller 305. The aluminum alloy pipe can be polished by the rotation of the grinding roller 305. As the rotating rod 303 rotates, the cam 306 is driven to rotate, and the rotation of the cam 306 can squeeze the extrusion plate 307 to move, and the movement of the extrusion plate 307 drives the piston rod 308 to move, and the movement of the piston rod 308 can drive the piston plate 309 to slide on the inner wall of the piston box 310. 09 The sliding movement can squeeze the air inside the piston box 310, so that the air can be transported to the air outlet hood 313 through the air guide pipe 312, and the air can be blown onto the grinding roller 305 through the air outlet hood 313, so that the debris generated when the aluminum alloy pipe is ground can be blown away, and the debris can be effectively prevented from remaining on the grinding roller 305, so that the grinding work can be better performed. As the rotating rod 1 303 rotates, the rotating rod 2 321 can be driven to rotate through the belt 1 320 transmission, and the rotating sleeve 323 can be driven to rotate through the rotating rod 2 321. The knocking plate 324 is driven to rotate through the rotating sleeve 323. The knocking plate 324 can knock the mold 406 after it rotates through the rotation of the knocking plate 324, so that the mold 406 can be vibrated, and the aluminum alloy pipe therein can be better demoulded, thereby improving work efficiency. The bearing capacity of the fixed plate 1 301 can be increased by installing the reinforcing rod 325, so that the work can be better performed.

[0049] When it is necessary to cast an aluminum alloy pipe, the operator clamps one end of the mold 406 with one end of the clamping pipe 405 to make them connected. At this time, the molten metal is injected into the mold 406 through the injection assembly 401. When the casting is completed, the movable cover installed at one end of the mold 406 is removed, and the rotating rod 3 408 is driven to rotate by starting the motor 2 409, and the fixed plate 3 407 is driven to rotate by the rotating rod 3 408. The mold 406 can be driven to rotate and swing by the rotation of the fixed plate 3 407. At this time, as the rotating rod 3 408 rotates, the rotating disk 410 can be driven to rotate. The movable rotating rod 411 rotates, and the movable block 412 can be driven to move by the rotation of the rotating rod 411, and the rotating rod 411 can move in the movable block 412, and the installation plate 403 can be driven to move by the movement of the movable block 412, and the telescopic rod 402 and the spring 404 can be squeezed by the movement of the installation plate 403, so that the clamping tube 405 can be separated from the mold 406, and the mold 406 can rotate and swing normally. When the demoulding is completed, the above steps are repeated to clamp the clamping tube 405 with one end of the mold 406, so that the demoulding work can be better performed, further improving the work efficiency and being more convenient to use;

[0050] When it is necessary to cast the aluminum alloy pipe, the operator casts the aluminum alloy pipe through the discharging mechanism 4. After the casting is completed, the aluminum alloy pipe is polished by the polishing mechanism 3. After the polishing is completed, the aluminum alloy pipe will move to the transmission roller 506 and the guide roller 507. At this time, as the rotating rod 1 303 rotates, the rotating rod 4 502 can be driven to rotate through the belt 2 501. The rotating rod 4 502 rotates and the half gear 503 rotates. The rotation of the half gear 503 can indirectly drive the gear 504 to rotate. The rotation of the gear 504 drives the rotating Rod five 505 rotates, and the driving roller 506 is driven to rotate by rotating rod five 505. The rotation of the driving roller 506 can drive the aluminum alloy pipe to move. As the aluminum alloy pipe moves, the guide roller 507 can be driven to rotate, so that the aluminum alloy pipe can be better guided and moved, and can be better collected. Since the half gear 503 can indirectly rotate the gear 504, and then the driving roller 506 can be indirectly rotated, the aluminum alloy pipe can be indirectly moved slowly, which makes it more convenient for operators to carry out subsequent collection and processing, thereby improving the convenience of the device.
