The lower mold part 2 includes a lower ring 201 and a second fixing frame 202. 02 and lower mold cavity 203, several second fixing frames 202 are fixedly connected to the upper part of the lower ring 201. The second fixing frames 202 are evenly arranged in a ring below the upper ring 101. The second fixing frames 202 are also configured as Y-shaped structures with three protrusions. The protrusions of the second fixing frames 202 are respectively fixedly connected to different lower mold cavities 203. The upper mold cavity 103 and the lower mold cavity 203 are spliced ​​to form a spherical mold cavity 3. The three spherical mold cavities 3 below any one of the first fixing frames 102 are spaced at the same distance from each other. The distance is set to 3-6cm. This application fixes the upper mold cavity 103 to the upper ring 101 via the first fixing frame 102, and the lower mold cavity 203 to the lower ring 201 via the second fixing frame 202. This allows operators to separate the upper mold cavity 103 and the lower mold cavity 203 by lifting the upper ring 101 and the lower ring 201 to add slurry, or to press the upper ring 101 and the lower ring 201 to close the upper mold cavity 103 and the lower mold cavity 203 to form a spherical mold cavity 3 for heating, rotation, and other processing operations. Simultaneously, both the first fixing frame 102 and the second fixing frame 202 are configured as Y-shaped structures with three protrusions, so that the three spherical mold cavities 3 connected to the first fixing frame 102 and the second fixing frame 202 form a triangular structure.
