An annular frame 6 is slidably connected between the plurality of slide grooves 7. The slide grooves 7 can limit the moving distance of the annular frame 6 so that it can move stably.

A support frame 10 is sleeved on the outer side of the connecting shaft, and an arc block 11 is fixed to the top of the support frame 10 by bolts. The power assembly causes the annular frame 6 to slide inward along the slide groove 7 on the fixed pipe 8, thereby rotating the first connecting rod 9 and the second connecting rod 12. At this time, the connection between the first connecting rod 9 and the second connecting rod 12 moves upward, so that the arc block 11 on the support frame 10 moves upward and contacts the inner wall of the cast pipe, thereby enabling the arc block 11 to support the cast pipe;

[0028] The cooling assembly 5 includes an annular water channel, an inlet pipe and an outlet pipe. The inlet pipe and the outlet pipe are connected to an external water source and power, so that external cooling water enters the annular water channel through the inlet pipe, then enters the outlet pipe through the annular water channel, and finally flows back to the external water source, and repeatedly circulates to cool the cast pipe.

[0029] In the present utility model, it should be noted that the power assembly includes an electric telescopic rod 13, which is fixed to the top of the slide 3 by bolts, and the extended end of the electric telescopic rod 13 passes through the slide 3 and is fixed with a slider 14 by bolts, and the slider 14 is fixed to the annular frame 6, and the slider 14 slides inside the fixed tube 8;

[0030] The support assembly includes a fixing frame 4, which is fixed to the bottom of the cooling assembly 5 by bolts. A positioning groove 21 is provided on the upper surface of the fixing frame 4. A positioning plate 20 is inserted into the positioning groove 21. An arc plate 17 is fixed to the top of the positioning plate 20 by bolts.

A plurality of rolling grooves 16 are provided on the top of the arc plate 17, and balls 15 are provided in the rolling grooves 16. The balls 15 assist the staff to smoothly move the cast pipe out of the arc plate 17. The cooling assembly 5 is located inside the slide 3, and the fixed pipe 8 is located inside the space surrounded by a plurality of second connecting rods 12 and the first connecting rod 9.

[0032] Working principle: When the cast pipe needs to be separated from the mold, firstly, one end of the base frame 1 on which the slide 3 is installed is docked with the external mold, so that the fixed tube 8 and its external components enter the interior of the cast tube, and then the electric telescopic rod 13 is started. The electric telescopic rod 13 contracts to cause the slider 14 to drive the annular frame 6 to slide inward along the fixed tube 8, thereby rotating the first connecting rod 9 and the second connecting rod 12. At this time, the connection between the first connecting rod 9 and the second connecting rod 12 moves upward, so that the arc block 11 on the support frame 10 moves upward and contacts the inner wall of the cast tube, and then the arc block 11 supports the cast tube, and the cooling assembly 5 cools the cast tube. Then, the slide 3 is pushed by an external machine or manually to move it outward along the guide rod 2, so that the supported cast tube gradually moves out of the mold until it is completely separated from the mold.
