[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1, with reference to Figure 1-4 A device for fixing a sand box for steel castings comprises a lower sand box 1 and an upper sand box 2. An L-shaped connecting rod 3 is clamped at the bottom corner of the lower sand box 1. A sleeve 4 is welded to the upper end of the L-shaped connecting rod 3. A clamping rod 6 is slidably inserted on the sleeve 4. A length adjustment structure is provided between the clamping rod 6 and the sleeve 4. The length adjustment structure comprises an adjusting pin 5 inserted at the top of the sleeve 4. Height adjustment holes 7 are opened at equal distances on the clamping rod 6. The adjusting pin 5 is plugged into the height adjustment hole 7.

[0023] A clamping block 8 is provided on the top side of the clamping rod 6, and the clamping block 8 is integrally formed with the clamping rod 6. A semicircular lifting ring 9 is provided on the top of the clamping rod 6, and the semicircular lifting ring 9 is integrally formed with the clamping rod 6;

[0024] The lower end surface of the clamping block 8 abuts against the corner of the upper end surface of the upper flask 2;

[0025] A socket 12 is provided on the top side of the card block 8, and an anti-slip assembly is connected to the socket 12. The anti-slip assembly includes a first plug-in block 10 and a second plug-in block 13 respectively plugged into the two sockets 12. A steel wire rope 11 is connected to one side of the first plug-in block 10, and a fixing structure is provided on the second plug-in block 13.

[0026] The fixing structure includes a through hole 14 formed on the second plug block 13 , through which the steel wire rope 11 passes. A locking bolt 15 is screwed onto the top of the second plug block 13 , and the bottom end of the locking bolt 15 abuts against the steel wire rope 11 .

[0027] Working principle: Clamp the L-shaped connecting rod 3 at the bottom corner of the lower sand box 1, insert the clamping rod 6 into the sleeve 4 and adjust the height of the clamping rod 6 up and down, then insert the adjusting pin 5 into the sleeve 4 and into the height adjustment hole 7 of the clamping rod 6, so that the clamping rod 6 is fixed, and then the clamping block 8 is clamped at the upper end corner of the upper sand box 2. If there is a gap between the clamping block 8 and the upper sand box 2, square steel can be cut into wedges to plug the gap between the clamping block 8 and the upper sand box 2, so that the clamping rod 6 is stable, and the lower sand box 1 and the upper sand box are fixed.
