[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] Embodiment: Through the personnel in this field, all the electrical components in this case are connected to their adapted power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection between the electrical components is completed in the working sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and does not explain the electrical control. Please refer to Figure 1-3 When in use, the plug-in strip 4 is inserted into the installation groove 3, so that the first outer semicircle wall 1 and the second outer semicircle wall 2 are buckled together. When making a sand casting mold, the buckled first outer semicircle wall 1 and the second outer semicircle wall 2 are buried in the specified position, the casting sand is compacted, and the molten liquid metal is injected into the casting cavity through the pouring port. The liquid metal flows into the space formed by the two vertical connecting walls 6, and then flows into the space formed by the two V-shaped liquid storage walls 8 through the two horizontal connecting walls 7, and finally fills the space formed by the two closed connecting walls 9. Metal is supplied when the workpiece is cast to prevent shrinkage cavities and shrinkage. The thermal insulation layer 5 plays a role in thermal insulation. The V-shaped liquid storage wall 8 is equivalent to extending into the insulation layer 5. The temperature of the molten liquid metal makes the insulation layer 5 attached to both sides of the V-shaped liquid storage wall 8 have a higher temperature, and this temperature is then transferred to the vertical connecting wall 6. At the same time, the molten liquid metal in the V-shaped liquid storage wall 8 also plays a role in isolating the temperature transfer between the vertical connecting wall 6 and the first outer semi-circle wall 1 and the second outer semi-circle wall 2, extending the cooling time of the molten liquid metal in the vertical connecting wall 6, improving the insulation efficiency, and preventing the molten liquid metal from cooling too fast at the riser during the casting process, resulting in poor casting effect.

[0019] As a preference, further, an inner ring heating layer 10 is embedded inside the thermal insulation layer 5 and close to the vertical connecting wall 6, and an outer ring heating layer 11 is embedded inside the thermal insulation layer 5 and close to the closed connecting wall 9, for heating the overall temperature of the device;

[0020] As a preferred embodiment, further, a connecting cover 12 is movably mounted on the outer wall surface of the first outer semicircular wall 1 and the second outer semicircular wall 2, a filling column 13 is installed on the connecting cover 12, the filling column 13 is movably fitted to the vertical connecting wall 6, and the connecting cover 12 is threadedly connected to the first outer semicircular wall 1 and the second outer semicircular wall 2;

[0021] After the first outer semi-circle wall 1 and the second outer semi-circle wall 2 are buckled together, the filling column 13 is aligned with the vertical connecting wall 6, and the connecting cover 12 is rotated on the outer wall surfaces of the first outer semi-circle wall 1 and the second outer semi-circle wall 2 to fix the first outer semi-circle wall 1 and the second outer semi-circle wall 2 in connection. After the first outer semi-circle wall 1 and the second outer semi-circle wall 2 are buried in designated positions, the connecting cover 12 is unscrewed from the first outer semi-circle wall 1 and the second outer semi-circle wall 2. After the casting work is completed, the first outer semi-circle wall 1 and the second outer semi-circle wall 2 are removed for reuse.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
