[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a cement building casting mold includes a casting tube 10. The outer periphery of the casting tube 10 is provided with uniformly distributed outer extension plates 11. Each group of outer extension plates 11 is provided with inner and outer layers. Each group of outer extension plates 11 is symmetrically arranged. Two adjacent groups of outer extension plates 11 are staggered horizontally and vertically. Two left-right symmetrical support frames 13 are fixedly arranged at the upper end of the casting tube 10. The two support frames 13 are engraved with scale grooves 18 uniformly distributed up and down. Two left-right symmetrical spring telescopic rods 17 are fixedly arranged at the upper end of the casting tube 10. The upper ends of the two spring telescopic rods 17 are connected with sliding frames 14. The sliding frames 14 are slidably matched with the support frames 13. The sliding frames 14 are threadedly connected with locking members 16, which can abut against the support frames 13. The lower ends of the two sliding frames 14 are fixed with pressing plates 15, which can It is able to slide with the pouring tube 10, and each outer extension plate 11 and the outer periphery of the lower end of the pouring tube 10 are provided with abutment grooves 19 distributed up and down, the abutment groove 19 at the upper end is located on the inner side, and the abutment groove 19 at the lower end is located on the outer side, and the peripheral side wall of each abutment groove 19 is provided with a magnetic ring 21, and a sealing gasket 20 is provided on the upper side or the lower side wall of each abutment groove 19. The two adjacent outer extension plates 11 are provided with a receiving cavity 23 at the ends close to each other, and a sliding plate 12 is slidably connected between the two adjacent receiving cavities 23. Each sliding plate 12 is rotatably connected with two rolling wheels symmetrical in upper and lower directions, and the rolling wheels abut against the peripheral surface of the pouring tube 10 or the outer extension plate 11, and a groove symmetrical to the rolling wheels is provided in the receiving cavity 23, and a protrusion 22 is fixed on each lower side abutment groove 19, and the outer extension plate 11 abuts against the protrusion 22;

[0020] Through the outer extension plates 11 arranged in the inner and outer layers, during the pouring of the cement column, the pouring pipe 10 is placed at the designated position, and then the pouring pipe 10 is pulled, and the pouring pipe 10 moves upward. The outer extension plates 11 located on the outer periphery of the pouring pipe 10 remain in the original position under the action of gravity. As the pouring pipe 10 rises, the two outer extension plates 11 lose contact with the pouring pipe 10. At this time, the upper end abutment groove 19 of the outer extension plate 11 and the lower end abutment groove 19 of the pouring pipe 10 are located at the same horizontal plane. Under the magnetic attraction of the magnetic ring 21, the two outer extension plates 11 located on the outer periphery of the casting pipe 10 are brought close to each other, and the sliding plate 12 between the two outer extension plates 11 is received in the receiving cavity 23 opened by the two outer extension plates 11. The rolling wheels on the sliding plate 12 are also retracted into the receiving cavity 23 under the setting of the slots. The two outer extension plates 11 abut against each other and the outer peripheral surface of the casting pipe 10, and the upper and lower side walls are sealed by the sealing gaskets 20 arranged above and below. Similarly, in the casting pipe 10, During the rising process, the outer extension plates 11 evenly distributed on the outer circumference are fitted one by one until the pouring pipe 10 stops. After the pouring pipe 10 rises to the specified position, it continues to rise so that the two outer extension plates 11 at the lower end can abut against each other and then stop. Then, the locking piece 16 is rotated to make the sliding frame 14 lose the abutment force between the locking piece 16 and the support frame 13, and the sliding frame 14 can slide up and down. The sliding frame 14 overcomes the spring force at the spring telescopic rod 17 and pushes downward, and the sliding frame 14 and the pressing plate 15 are in contact. The height position of the sliding frame 14 is determined by the graduated groove 18 on the support frame 13. After the sliding frame 14 is lowered to the corresponding position, the sliding frame 14 is fixed on the support frame 13 by rotating the locking member 16. The upper end of the cement column is sealed by the pressing plate 15. When storing, the outer extension plate 11 is rotated so that the outer extension plate 11 expands outward under the push of the protrusion 22, so that the outer extension plate 11 is reset on the outer periphery of the casting pipe 10, and the casting pipe 10 can slide downward.

[0021] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
