[0028] The working principle of the utility model is as follows: the ceramic core forming mold is additionally provided with an unfolding mechanism 3 and a docking mechanism 4. Before using the ceramic core forming mold which is easy to demold, it is necessary to pre-install the ceramic core forming mold above the conveyor belt through the hanging plate 301, and it is necessary to pre-connect the first pneumatic rod 303, the second pneumatic rod 307, the first driving pneumatic rod 402 and the second driving pneumatic rod 405 to electricity and the control terminal. When using the ceramic core forming mold which is easy to demold, the docking mechanism 4 is activated, the first driving pneumatic rod 402 and the second driving pneumatic rod 405 are started, the first driving pneumatic rod 402 pushes the first push plate 403 backward, and the second driving pneumatic rod 405 pushes the second push plate 406 forward, so that the upper mold 1 and the lower mold 2 are closely fitted, and the molding material is injected into the upper mold 1 and the lower mold 2. When the molding in the upper mold 1 and the lower mold 2 is completed, the unfolding mechanism 3 and the docking mechanism 4 are activated, the first driving pneumatic rod 402 in the docking mechanism 4 moves forward, and the second driving pneumatic rod 405 moves backward, and the upper mold is no longer restricted. 1 and the lower mold 2, start the first pneumatic rod 303 and the second pneumatic rod 307 inside the unfolding mechanism 3, the first pneumatic rod 303 pulls the first connecting block 304 and the second connecting shaft frame 305 from bottom to top, and at the same time, the second pneumatic rod 307 pulls the second connecting block 308 and the fourth connecting shaft frame 309 from bottom to top, thereby driving the upper mold 1 to flip forward and driving the lower mold 2 to flip backward, so as to achieve the effect of unfolding the upper mold 1 and the lower mold 2. At this time, the molding structure in the middle of the upper mold 1 and the lower mold 2 will fall off from the upper mold 1 and the lower mold 2; in summary, the unfolding mechanism 3 adopts a pneumatic structure and a double-opening structure, drives the upper mold 1 and the lower mold 2 from both ends, and can quickly unfold or close the upper mold 1 and the lower mold 2, which not only improves the efficiency of the casting molding structure, but also allows the molding structure to fall off quickly, achieving the effect of rapid demoulding, and the docking mechanism 4 cooperates with the unfolding mechanism 3 to clamp the upper mold 1 and the lower mold 2 to ensure the stability and reliability of the molding operation of the upper mold 1 and the lower mold 2.
