[0049] A connecting frame 214 is installed on the connecting rod 213, and a centrifugal casting mold 215 is rotatably provided at one end of the connecting frame 214.

A chain 219 is provided on the outside of the sprocket a216 and the sprocket b218, and the chain 219 is engaged with the sprocket a216 and the sprocket b218.

[0050] The driving assembly 22 includes: a rotating sleeve 221, which is rotatably arranged on the outside of the rotating sleeve 104; a gear a222, which is installed on the top of the rotating sleeve 221; a gear b223, which is installed on the rotating rod 217, and the gears a222 and b223 correspond to each other; a rotating driving member a224 and a rotating driving member b225 are installed in the fixed frame 100; a gear c226 is installed on the rotating sleeve 221, and a gear d227 is installed on the output end of the rotating driving member a224, and the gears c226 and d227 are engaged with each other; a gear e228 is installed on the rotating sleeve 104, and a gear f229 is installed on the output end of the rotating driving member b225, and the gears e228 and f229 are engaged with each other.

[0051] In this embodiment, the rotating driving member b225 drives the gear f229 to rotate, drives the gear e228 and the rotating sleeve 104 to rotate, and drives 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 below the pouring 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 b225 is preferably a servo motor to enable the sliding rod 234 to slide to point a of the inner arc segment 10311 and stop at point b of the outer arc segment 10312 to achieve a positioning effect.

[0052] 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 liquid into the rotating centrifugal casting mold 215, and the rotating centrifugal casting mold 215 performs centrifugal casting on the breathing tube.

[0053] The flip unloading assembly 23 includes: a rack segment 231, which is installed under the fixed disk a103; a gear g232, which is installed on the connecting rod 213, and the gear g232 corresponds to the rack segment 231; a mounting sleeve 233, which is rotatably arranged on the outside of the connecting rod 213; a sliding rod 234, which is installed on the mounting sleeve 233, and a sliding groove 1031 is provided under the fixed disk a103, and the sliding rod 234 slides in the sliding groove 1031. A guide rod 235 is installed on the mounting sleeve 233, and a card slot 2331 is opened in the mounting sleeve 233. A convex ring 2132 is provided on the connecting rod 213, and the convex ring 2132 rotates in the card slot 2331. The guide rod 235 passes through the fixed seat 105.

[0054] The slide groove 1031 includes an inner arc segment 10311 and an outer arc segment 10312 . The outer arc segment 10312 is connected to the inner arc segment 10311 . The size of the outer arc segment 10312 is larger than that of the inner arc segment 10311 .

[0055] In this embodiment, the rotary drive member b225 drives the gear f229 to rotate, driving the centrifugal casting mold 215 of the centrifugal casting assembly 21 to rotate about the axis of the rotating sleeve 104. 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 moves away from the gear a222 (the two are not meshing), and the gear g232 moves to correspond to the position of the rack segment 231.

[0056] The centrifugal casting mold 215 continues to rotate around the axis of the rotating sleeve 104, and the gear g232 engages 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. At this time, the sliding rod 234 slides to Figure 5 At point b of the outer arc segment 10312.

[0057] It should be noted that: when the sliding rod 234 slides in the inner arc segment 10311, the gear b223 engages with the gear a222, and the movement of the gear g232 is staggered with the rack segment 231. When the sliding rod 234 slides in the outer arc segment 10312, the gear b223 moves away from the gear a222, and the two do not engage, and the movement of the gear g232 corresponds to the position of the rack segment 231.

[0058] It should also be noted that: 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 until the gear g232 is disengaged from the rack segment 231. At this time, under the action of the elastic connecting member 212, the connecting sleeve 211 is driven to rotate 180 degrees and reset to the initial state). That is to say, in the absence of external force, the elastic torque of the elastic connecting member 212 drives the connecting sleeve 211 and the connecting rod 213 to the initial state.

[0067] In this embodiment, 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 moderately preheat the centrifugal casting mold 215. The centrifugal casting mold 215 expands due to heat, and the gap between the centrifugal casting mold 215 and the breathing tube is increased to prevent the breathing tube from sticking to the inner wall of the centrifugal casting mold 215.

[0068] 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.

[0069] In this embodiment, the air compressor 400 introduces high-pressure gas into the air inlet 2145 through the air pipe 423 and the air injection pipe 422, and then ejects the gas through the air injection hole 2155, blowing the breathing tube in the centrifugal casting mold 215 into the collection box 106, completing the unloading of the breathing tube.

[0070] 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.

[0071] Embodiment 3: This embodiment provides a casting method for a breathing tube production casting device, comprising the following steps:

[0072] Step 1, pouring process: Rotate the driving member b225 to drive the gear f229 to rotate, drive the gear e228 and the rotating sleeve 104 to rotate, drive 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 pouring mechanism 3, at this time the sliding rod 234 slides to Figure 5 At point a of the inner arc segment 10311;

[0073] Rotating drive member a224 drives gear d227 to rotate, which in turn drives gear c226 and rotating sleeve 221 to rotate synchronously. This drives gear a222 to rotate, which in turn drives gear b223 and rotating rod 217 to rotate. This drives centrifugal casting mold 215 to rotate about its axis via chain 219, sprocket a216, and sprocket b218. The pouring mechanism 3 pours molten metal into the rotating centrifugal casting mold 215, which then centrifugally casts the breathing tube.

[0074] 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. 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 moves away from the gear a222 (the two are not meshing), and the gear g232 moves to correspond to the position of the rack segment 231.

[0075] The centrifugal casting mold 215 continues to rotate around the axis of the rotating sleeve 104, and the gear g232 engages 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. 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;

[0076] 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 centrifugal casting mold 215 corresponding to it on the other side is located at the pouring mechanism 3 (pouring station). That is, one centrifugal casting mold 215 is performing the pouring process while the other centrifugal casting mold 215 that has been cast is cooling and unloading. The two processes can be carried out simultaneously without interfering with each other, which saves time and improves production efficiency.

[0077] Step 3: Cooling process: The linear drive member a405 drives the lifting block 404 to move downward, driving the water inlet pipe 407 to be inserted into the water inlet hole 2141, the drain pipe 408 to be inserted into the drain hole 2142, and the air injection pipe 422 to be inserted into the air inlet hole 2145. The second water pump 421 injects cold water from the cold water tank 420 into the cooling tank 2153 to cool the centrifugal casting mold 215 and the breathing tube inside the centrifugal casting mold 215;

[0078] 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.

[0079] 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. The first water pump 419 injects the hot water in the hot water tank 418 into the cooling tank 2153 to moderately preheat the centrifugal casting mold 215. The centrifugal casting mold 215 expands due to heat, and the gap between the centrifugal casting mold 215 and the breathing tube is increased to prevent the breathing tube from sticking to the inner wall of the centrifugal casting mold 215.

[0080] 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;

[0081] 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. The high-pressure gas is then ejected through the air jet hole 2155, blowing the breathing tube in the centrifugal casting mold 215 into the collection box 106, completing the unloading of the breathing tube;

[0082] 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.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
