[0043] In this embodiment, the rotating drive member c414 drives the rotating disk 415 to rotate until the two hot water pipes 416 correspond to the positions of the first pipe 410 and the second pipe 411 respectively, and the first water pump 419 injects the hot water in the hot water tank 418 into the cooling tank 2153 to appropriately preheat the centrifugal casting mold 215. The volume of the centrifugal casting mold 215 expands due to heat, which increases the gap between the centrifugal casting mold 215 and the breathing tube, thereby preventing the breathing tube from sticking to the inner wall of the centrifugal casting mold 215.

[0044] The water route is: hot water tank 418 → hot water pipe 416 → first pipe 410 → first hose 412 → water inlet pipe 407 → water inlet hole 2141 → water inlet groove 2143 → first annular groove 2151 → cooling groove 2153 → second annular groove 2152 → drainage groove 2144 → drainage hole 2142 → drainage pipe 408 → second hose 413 → second pipe 411 → hot water pipe 416 → hot water tank 418.

[0045] In this embodiment, the air compressor 400 introduces high-pressure gas into the air inlet 2145 through the air pipe 423 and the air jet pipe 422, and then ejects the gas through the air jet hole 2155, blowing the breathing tube in the centrifugal casting mold 215 into the collection box 106, thus completing the unloading of the breathing tube; The direction of the gas path is: air compressor 400 → air pipe 423 → injection pipe 422 → air inlet hole 2145 → air inlet groove 2146 → third annular groove 2154 → injection hole 2155.

[0046] Embodiment 3: This embodiment provides a casting method for a breathing tube production casting device, comprising the following steps: Step 1: Casting process: The rotating driving member b225 drives the gear f229 to rotate, and the gear e228 and the rotating sleeve 104 rotate, driving the centrifugal casting mold 215 of the centrifugal casting assembly 21 to rotate around the axis of the rotating sleeve 104 until the centrifugal casting mold 215 is driven to move to the bottom of the casting mechanism 3. At this time, the sliding rod 234 slides to Figure 5 At point a of the inner arc segment 10311; The rotating driving member a224 drives the gear d227 to rotate, driving the gear c226 and the rotating sleeve 221 to rotate synchronously, driving the gear a222 to rotate, driving the gear b223 and the rotating rod 217 to rotate, and driving the centrifugal casting mold 215 to rotate around its axis through the chain 219 and the sprocket a216 and the sprocket b218; the pouring mechanism 3 pours the molten metal into the rotating centrifugal casting mold 215, and the rotating centrifugal casting mold 215 performs centrifugal casting on the breathing tube; Step 2, flipping process: the rotating driving member b225 drives the gear f229 to rotate, driving the centrifugal casting mold 215 of the centrifugal casting assembly 21 to rotate around the axis of the rotating sleeve 104, and the sliding rod 234 slides from the inner arc segment 10311 to the outer arc segment 10312, driving the connecting rod 213 to slide outward along the connecting sleeve 211, at this time, the gear b223 is away from the gear a222 (the two are not meshed), and the gear g232 moves to correspond to the position of the rack segment 231; The centrifugal casting mold 215 continues to rotate around the axis of the rotating sleeve 104, and the gear g232 meshes with the rack segment 231, driving the connecting rod 213 and the rotating sleeve 221 to rotate 180 degrees, driving the centrifugal casting mold 215 to flip 180 degrees, and the centrifugal casting mold 215 is located at the cooling mechanism 4. At this time, the sliding rod 234 slides to Figure 5 At point b of the outer arc segment 10312; It should be noted that: Figure 1 As shown, there are four centrifugal casting molds 215 in this embodiment. When one of the centrifugal casting molds 215 is located at the cooling mechanism 4 (cooling station), the other centrifugal casting mold 215 corresponding thereto is located at the pouring mechanism 3 (pouring station). That is to say, one centrifugal casting mold 215 is undergoing the pouring process while the other centrifugal casting mold 215 that has been cast is undergoing cooling and unloading. The two processes can be carried out simultaneously without interfering with each other, thereby saving time and improving production efficiency.

[0047] Step 3, cooling process: the linear driving member a405 drives the lifting block 404 to move downward, drives the water inlet pipe 407 to insert into the water inlet hole 2141, the drain pipe 408 to insert into the drain hole 2142, the jet pipe 422 to insert into the air inlet hole 2145, and the second water pump 421 injects the cold water in the cold water tank 420 into the cooling tank 2153 to cool the centrifugal casting mold 215 and the breathing tube in the centrifugal casting mold 215; The water path is: cold water tank 420 → cold water pipe 417 → first pipe 410 → first hose 412 → water inlet pipe 407 → water inlet hole 2141 → water inlet groove 2143 → first annular groove 2151 → cooling groove 2153 → second annular groove 2152 → drainage groove 2144 → drainage hole 2142 → drainage pipe 408 → second hose 413 → second pipe 411 → cold water pipe 417 → cold water tank 420.

[0048] Step 4, preheating process: the rotating driving member c414 drives the rotating disk 415 to rotate until the two hot water pipes 416 correspond to the positions of the first pipe 410 and the second pipe 411 respectively, and the first water pump 419 injects the hot water in the hot water tank 418 into the cooling tank 2153 to appropriately preheat the centrifugal casting mold 215. The volume of the centrifugal casting mold 215 expands due to heat, which increases the gap between the centrifugal casting mold 215 and the breathing tube, thereby preventing the breathing tube from sticking to the inner wall of the centrifugal casting mold 215.

[0049] The water path is: hot water tank 418 → hot water pipe 416 → first pipe 410 → first hose 412 → water inlet pipe 407 → water inlet hole 2141 → water inlet groove 2143 → first annular groove 2151 → cooling groove 2153 → second annular groove 2152 → drainage groove 2144 → drainage hole 2142 → drainage pipe 408 → second hose 413 → second pipe 411 → hot water pipe 416 → hot water tank 418; Step 5, unloading process: the air compressor 400 introduces high-pressure gas into the air inlet 2145 through the air pipe 423 and the air jet pipe 422, and then ejects the gas through the air jet hole 2155, blowing the breathing tube in the centrifugal casting mold 215 into the collection box 106, thus completing the unloading of the breathing tube; The direction of the gas path is: air compressor 400 → air pipe 423 → injection pipe 422 → air inlet hole 2145 → air inlet groove 2146 → third annular groove 2154 → injection hole 2155.
