[0051] The working principle and use process of the present invention are as follows: when it is necessary to cast a cement rod, the lower mold shell 14 is placed on the surfaces of the two positioning seats 13, and then the two positioning blocks 16 are symmetrically placed inside the lower mold shell 14, and the two ends of two tension springs 117 of different diameters are respectively inserted into the two spiral grooves 116. The tension springs 117 are provided so that after the casting is completed, the tension springs 117 can strengthen the vertical stress of the cement rod to prevent the cement rod from splitting during use, and then the two positioning blocks 16 are brought close to each other, and a plurality of supporting steel bars 18 are respectively inserted into the limiting holes 17, and then one of the positioning blocks 16 is rotated to make the supporting steel bars 18 move laterally inside the limiting holes 17. Due to the shape of the limiting holes 17, the supporting steel bars 18 will be slowly squeezed, so that the positioning blocks 16 The friction between the support steel bar 18 and the support steel bar 18 increases. When the support steel bar 18 moves laterally inside the limiting hole 17, the support steel bar 18 will squeeze the limiting tooth 115, and the limiting tooth 115 will rotate through the rotating shaft A until the support steel bar 18 can no longer move. The limiting tooth 115 will clamp the support steel bar 18 to prevent the support steel bar 18 from moving. Then, the positioning block 16 that clamps the support steel bar 18 is moved inside the lower mold shell 14 to make the two positioning blocks 16 move away from each other. The two tension springs 117 will also be stretched until they move to a suitable position, and then another positioning block 16 will position several support steel bars 18, so that workers can install the support steel bars 18 more quickly, strengthen the stress of the poured cement rod, and prevent it from breaking during use. The upper mold shell 15 covers the upper surface of the lower mold shell 14, and the lower mold shell 14 and the upper mold shell 15 are connected to each other by a screw to wrap the positioning block 16, and then the limiting rod 19 passes through the interior of the two positioning blocks 16, so that the limiting plate 113 is wrapped on the surface of the lower mold shell 14 and the upper mold shell 15 to achieve sealing of the lower mold shell 14 and the upper mold shell 15. When it is necessary to pour cement, the cement pipe is inserted into the interior of the lower mold shell 14 through the feed hole A111 and the feed hole B114, and then the cement is poured into the interior of the lower mold shell 14 through the cement pipe. When the cement pouring is completed, the cement pipe is pulled out from the inside of the feed hole A111, and then force is applied to the handle 112 to rotate it, so that the feed hole B114 and the feed hole A111 are misaligned with each other to achieve the lower mold shell 14 and the upper mold The sealing of the shell 15 and the limit rod 19 can make the poured cement rod appear hollow, so that when the supporting force remains unchanged, it not only reduces the weight but also reduces the material used, which is more practical. Then, the support rod 31 is rotated so that the four extrusion plates 32 can fit on the surface of the upper mold shell 15, and then the retaining plate 34 is put on the surface of the two support columns 35 to position the lower mold shell 14 and the upper mold shell 15 to prevent movement. Then, the motor 21 is connected to an external power supply and then started. The positioning rod 22 will rotate inside the positioning groove A, and the synchronous wheel B will drive the synchronous wheel C to rotate through the first synchronous belt 23, thereby driving one of the limit rods 24 to rotate. The limit rod 24 then drives several limit rods 24 to rotate through several synchronous wheels A and several second synchronous belts 26.The rubber rollers 25 drive the lower mold shell 14 and the upper mold shell 15 to rotate, which not only reduces the bubbles inside the cement, but also makes the cement molding more regular and round, and also facilitates demoulding. When the lower mold shell 14 and the upper mold shell 15 rotate, the positioning roller 33 will be driven to rotate inside the positioning groove B, so that the lower mold shell 14 and the upper mold shell 15 rotate more smoothly. After the centrifugation is completed, the lower mold shell 14 and the upper mold shell 15 are sent to a special drying area, so that the cement rod is formed faster, and the casting of the cement rod is realized.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
