[0002] In the prior art, the box clamping device is used to fasten the sand box during the pouring process to prevent the molten metal from lifting the box and causing fire or deformation of the casting box;

[0003] Traditional clamping boxes usually adopt manual clamping methods, which use clamps such as screw clamping boxes, U-shaped clamping boxes and iron clamping boxes to clamp the sand box;

[0004] However, during use, the size and required clamping force of the sand box vary depending on the casting product. Traditional clamps need to be used in conjunction with the sand box. The interchangeability of clamps for various sand boxes is poor. In addition, traditional manual locking clamps are time-consuming and labor-intensive, which does not meet the needs of the production line. Traditional hydraulic locking clamps are often fixed at a certain position and cannot move with the sand box. As a result, they can only stagnate at the clamping position during the pressure holding process, wasting time and reducing production efficiency.

[0005] Therefore, how to provide a new intelligent card box device that can automatically clamp different sand boxes and move with the sand boxes to reduce the waste of holding time in assembly line operations is an urgent problem that technical personnel in this field need to solve.
