The threaded tube 29 then rotates the threaded rod 210, causing the lower mold 12 to move upwards, thus compressing the clay 13 and completing the process. After the molding process is completed, the upper mold 11 and lower mold 12 are removed. Then, the third motor 34 is started, which drives the second lead screw 35 to rotate. The second lead screw 35 drives the connecting rod 36 to move.
