After the rotating rod and stirring rod have moved out of the inside of the sand bucket, the electric telescopic rod is turned off. Then, the bolt is loosened and unscrewed from the threaded hole. The separation of the bolt and the threaded hole causes the displacement plate to lose its limit inside the long groove. At this time, the displacement plate can be moved.

The rotating rod and stirring rod are moved away from directly above the sand bucket, and the sliding displacement plate continues to slide out from the inside of the long groove. After the displacement plate slides out from the inside of the long groove, the sliding seat also slides out from the inside of the groove, thus completing the corresponding disassembly operation. Finally, the shell core machine is started. First, the core box is closed to prepare for sand filling and compaction. Then, the core sand inside the sand bucket is introduced into the core box through the connecting pipe and sand inlet channel and heated to harden the coated sand in the hot core box. Finally, the excess sand is poured out by the rotary mechanism after heating and hardening, forming the required shell core. Through the cooperation of the above structure, the rotating rod and stirring rod can be removed from the inside of the sand bucket and the shell core machine after stirring, thus avoiding affecting the subsequent shell core processing operation.
