All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1-4 An embodiment of this utility model is provided: a sand mold structure for ordinary cast alumina products, including a base 1, corner seats 2 are provided at the corner positions at the bottom of the base 1, and a guide rod 3 is movably connected to one side inside the corner seat 2, with both ends of the guide rod 3 extending to the outside of the corner seat 2.

[0022] In use, the guide rod 3 is used to limit the movement range of the connecting seat 6;

[0023] The bottom end of the guide rod 3 is provided with a connecting seat 6, the bottom end of the connecting seat 6 is provided with a foot seat 7, and the corner positions inside the foot seat 7 are provided with positioning holes 8.

[0024] In use, the positioning hole 8 is provided to allow the foot 7 to be bolted in.

[0025] The bottom of the corner seat 2 on one side of the guide rod 3 is provided with a hexagonal nut 4. An adjusting bolt 5 is installed in the internal thread of the hexagonal nut 4. The top of the adjusting bolt 5 extends to the outside of the hexagonal nut 4, and the bottom of the adjusting bolt 5 passes through the corner seat 2 and is rotatably connected to the top of the connecting seat 6.

[0026] In use, the height of the foot 7 can be adjusted by adjusting the setting of the bolt 5 and the hexagonal nut 4;

[0027] The base 1 has a lower sand mold 9 at its top, and an upper sand mold 10 is installed above the lower sand mold 9. The upper sand mold 10 has placement grooves 12 on both sides of its bottom. The lower sand mold 9, located below the placement grooves 12, has an arc-shaped magnetic block 11 and a rectangular magnetic block 17 at its top. The tops of the arc-shaped magnetic block 11 and the rectangular magnetic block 17 are attracted to the inner wall of the placement groove 12. A sand mold is installed at the top of the lower sand mold 9 between the rectangular magnetic block 17 and the arc-shaped magnetic block 11. The sand mold core 20 has a lower sand mold 9 with equally spaced strip grooves 18 on its top. Strip blocks 19 are inserted into the inside of the strip grooves 18. The top of the strip blocks 19 extends to the outside of the strip grooves 18 and connects to the bottom of the sand mold core 20. The upper sand mold 10 has a pouring gate 21 at the center of its top. The upper sand mold 10 has a protective cylinder 13 on its top outside the pouring gate 21. A connecting strip 16 is provided on the outer wall of one side of the protective cylinder 13.

[0028] In use, the connecting strap 16 is used to connect the protective cylinder 13 and the protective cover 14.

[0029] A protective cover 14 is provided at the end of the connecting belt 16 away from the protective cylinder 13, and a sealing ring 15 is provided on the inner wall of the protective cover 14;

[0031] In this embodiment, the adjusting bolt 5 is first turned to rotate and slide inside the hexagonal nut 4, causing the adjusting bolt 5 to drive the connecting seat 6 to move up and down. This, in turn, causes the connecting seat 6 to slide the guide rod 3 inside the corner seat 2, adjusting the distance between the corner seat 2 and the foot seat 7 to adjust the overall height of the sand mold structure as needed. Then, by using bolts to pass through the positioning hole 8 and screw them into the threaded hole reserved on the mounting platform, the sand mold structure is bolted and positioned. Afterwards, by inserting the strip block 19 into the inner side of the strip groove 18, the sand mold core 20 is installed between the arc-shaped magnetic block 11 and the rectangular magnetic block 17. Finally, the placement groove 12 is aligned with the arc-shaped magnetic block 11 and the rectangular magnetic block 17. The magnetic block 17 magnetically attaches the upper sand mold 10 to the top of the lower sand mold 9, allowing for quick installation of the sand mold structure. It also facilitates the disassembly of the lower sand mold 9 and the upper sand mold 10, and the removal of the sand mold core 20. Finally, by pressing down on the protective cover 14, the sealing ring 15 is inserted into the inside of the protective cylinder 13, allowing the protective cover 14 to close on the top of the protective cylinder 13. The protective cylinder 13, together with the protective cover 14, blocks and protects the pouring port 21, effectively reducing the inflow of external dust and other contaminants into the inner side of the upper sand mold 10 through the pouring port 21, thus reducing the corrosion of the sand mold core 20 by dust and completing the use of the sand mold structure.
