[0029] The present application starts the driving mechanism 6 to drive the transmission mechanism 2 and the rotating sleeve 5 to rotate synchronously, so as to drive each mold 3 to move one by one to the bottom of the casting pipe 501 away from the end of the rotating sleeve 5. At the same time, the metal liquid in the storage tank 4 will flow into the mold 3 under the action of gravity. At the same time, after the casting pipe 501 rotates to a certain angle away from the end of the rotating sleeve 5, the metal liquid will no longer flow down from this casting pipe 501, thereby preventing the metal liquid from flowing from the gap of the mold 3 to the ground, thereby improving the utilization rate of the metal liquid; realizing the assembly line casting production of metal castings and improving production efficiency.

[0030] Reference Figure 2 : The transmission mechanism 2 includes: a transmission gear 201 and a transmission chain 202. The transmission gears 201 are rotatably provided at the opposite ends of the conveying frame 1. The transmission gear 201 is in the shape of an "I", and the transmission chains 202 are respectively engaged and sleeved on the opposite sides. The opposite ends of the mold 3 are respectively horizontally rotatably provided on the transmission chain 202.

[0031] In the present application, the driving mechanism 6 is started to drive the rotating chain to rotate around the transmission gear 201 , thereby moving the molds 3 one by one to below the casting pipe 501 .

[0032] Reference Figure 2 : The driving mechanism 6 includes: a rotating roller 601, a driving gear 602 and an intermittent driving component 603. The rotating roller 601 is horizontally rotatably arranged on the conveying frame 1, and its roller body is coaxially provided with a driving gear 602 that meshes with the transmission chain 202. One end of the rotating roller 601 is coaxially arranged on the rotating sleeve 5. The intermittent driving component 603 is arranged on the conveying frame 1 and can drive the rotating roller 601 to rotate.

[0033] The present application starts the intermittent drive assembly 603 to drive the rotating roller 601 to rotate, thereby driving the rotating roller 601 to rotate, and then driving the rotating sleeve 5 to rotate synchronously. At the same time, the transmission chain 202 is driven to rotate synchronously through the driving gear 602 to ensure that the casting pipe 501 moves synchronously with the mold 3 to prevent the metal liquid from flowing to the ground.

[0034] Reference Figure 3-Figure 5 : The rotating roller 601 is coaxially provided with a spline shaft 60101 near one end of the rotating sleeve 5, and the rotating sleeve 5 is provided with a spline groove 502 adapted to the spline shaft 60101.

[0035] This application uses this design to ensure that the rotating roller 601 rotates synchronously with the rotating sleeve 5.

[0036] Reference Figure 3: The intermittent drive component 603 includes: a drive motor 60301, a drive wheel 60302 and a transmission wheel 60303. The transmission wheel 60303 is coaxially arranged at one end of the rotating roller 601 away from the rotating sleeve 5. The drive motor 60301 is arranged on the conveying frame 1, and its output shaft is coaxially arranged with a drive wheel 60302 that meshes with the transmission wheel 60303.

[0037] In this application, the driving motor 60301 is started to drive the driving wheel 60302 to rotate, thereby driving the transmission wheel 60303 to rotate, thereby realizing the rotation of the rotating roller 601.

[0038] Reference Figure 4 : The transmission wheel 60303 is coaxially and spaced apart with a plurality of driving grooves 6030301 and a limiting groove 6030302 engaged with the driving wheel 60302. The driving wheel 60302 is provided with a driving rod 6030201 adapted to the driving groove 6030301 and an avoidance groove 6030202 for avoiding the transmission wheel 60303.

[0039] This design of the present application is a "groove wheel mechanism", also known as a "Geneva mechanism", which realizes the intermittent rotation of the rotating roller 601 to ensure that the casting pipe 501 stays above each mold 3 for a period of time, thereby completing the casting and ensuring product quality.

[0040] Reference Figure 2 The storage tank 4 is tilted and arranged on one side of the conveying frame 1, and a feeding port 402 is opened on the top thereof.

[0041] The user of the present application can add molten metal into the storage tank 4 through the feeding port 402, and the molten metal flows into the rotating sleeve 5 under the action of gravity. At the same time, the storage tank 4 is tilted to accelerate the outflow speed of the molten metal.

[0042] When the device provided by the present invention is in use, the driving mechanism 6 is started to drive the transmission mechanism 2 and the rotating sleeve 5 to rotate synchronously, so as to drive each mold 3 to move one by one to the bottom of the casting pipe 501 away from the end of the rotating sleeve 5.
