[0003] However, in the current process of manufacturing calcium silicate shells, the mold is usually cylindrical, and a cylindrical inner core is fixed inside the mold; the formed calcium silicate shell is tubular. Before installing the calcium silicate shell, according to the diameter and length of the pipeline, the calcium silicate shell is cut into two or more pieces using scissors, saws or other appropriate tools, which causes the problem of cutting and manufacturing dust during the on-site construction of the calcium silicate shell.
[0004] Moreover, the diameter of the inner core inside the mold is generally customized according to the diameter of the pipeline, resulting in the need to customize inner cores with different diameters for different diameters of pipelines, and thus the entire set of molds needs to be replaced. Finally, due to the entrapment of air when the mold is filled with slurry, there are voids inside the formed calcium silicate shell, affecting its overall strength. Therefore, those skilled in the art propose a solution for the calcium silicate shell forming mold here. Summary of the Utility Model

[0030] Refer to the attached drawings of the specification Figure 2 as shown; the split mold 2 includes two semi-circular shells 21, and two partition plates 25 are fixed to the end faces of the semi-circular shells 21 close to each other, and slide bars 24 are fixed to the surfaces of the partition plates 25 away from each other; the replaceable inner core 3 includes a small-diameter inner core 31 and a large-diameter inner core 32, and sliding grooves 33 adapted to the slide bars 24 are formed on the rectangular surfaces of the small-diameter inner core 31 and the large-diameter inner core 32.
[0031] Refer to the attached drawings of the specification Figure 4 as shown; the diameter of the small-diameter inner core 31 is 1 / 2 of the diameter of the large-diameter inner core 32, and the spacing of the sliding grooves 33 on the rectangular surfaces of the small-diameter inner core 31 and the large-diameter inner core 32 is the same, for adapting to the slide bars 24 with the same fixed distance. Chambers 22 for pouring slurry are formed in the interiors of the semi-circular shells 21, and the cross-sections of the semi-circular shells 21 are all semi-circular; a plurality of lifting lugs 23 are equidistantly fixed to the edge positions of the semi-circular shells 21 close to each other, and bolts are arranged between the lifting lugs 23 to lock the two semi-circular shells 21.
[0032] Refer to the attached drawings of the specification Figure 3 as shown; three supporting feet 13 are annularly and arrayedly fixed to the bottom surface of the bottom shell 11, and the bottom side wall of the inner cavity of the bottom shell 11 and the bottom of the outer shell of the vibration motor 12 are locked and connected by screws. A support plate 14 is fixed to the bottom surface of the outer cylinder 15, and the bottom surface of the support plate 14 is connected to the vibration end face of the vibration motor 12.
