It continuously produces metal castings by continuously pouring molten metal into a mold in the continuous casting machine.

[0003] In the prior art, molten metal, also known as casting liquid, is transported through a pipeline to a mold transported above a conveying rail for casting processing. A solenoid valve is installed on the pipeline to control the conveying state of the casting liquid. However, residual casting liquid still appears on the inner wall of the pipeline below the solenoid valve, so that during the intermittent conveying of the mold, the casting liquid on the inner wall of the pipeline will directly drip onto the conveying rail. Long-term dripping will damage the conveying rail and increase the difficulty of cleaning the continuous casting device.

[0004] In summary, the utility model provides a continuous casting device for casting to solve the above problems. Utility Model Content

[0007] Furthermore, the quantity controlled discharge assembly includes four electric lifting rods, which are all fixedly connected to the bottom of the connecting plate, a transmission plate is fixedly connected between the output ends of the four electric lifting rods, a feed pipe passes through the top and bottom of the transmission plate, an air pump is fixedly connected to one side of the bottom of the transmission plate, the bottom end of the feed pipe is connected to a buffer tube, and a protective cover is provided on the outer tube surface of the buffer tube and directly above a groove.

[0008] Furthermore, the bottom of the protective cover is matched with the groove on the top of the casting mold, and the buffer tube is fixedly connected to the protective cover.

[0009] Furthermore, the air outlet end of the air pump is connected to an air outlet pipe, and one end of the air outlet pipe extends to the top of one side of the buffer tube.

[0010] Furthermore, the air inlet end of the air pump is connected to an air inlet pipe, and a second one-way valve is installed on the air outlet pipe.

[0011] Furthermore, the bottom end of the buffer tube is connected to a first one-way valve, and the groove is in a circular ring shape.

[0012] Furthermore, the feed pipe is fixedly connected to the transmission plate, and the air outlet pipe is communicated with the buffer pipe.

[0013] Beneficial effects of the utility model:
