[0002] The combined sand box fixing device for sand casting is a device used in sand casting to reinforce and install the assembled sand box.

[0003] Based on the above, the inventors have discovered that there are currently many combined sand box fixing devices for sand casting on the market. However, in general, these devices are installed by workers directly engaging the upper and lower sand molds through grooves and protrusions. After assembly, the sand box connection is easily loosened and detached when subjected to external force, thus affecting the normal use of the device. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a combined sand box fixing device for sand casting, aiming to achieve a more practical purpose.

The outer wall of the stud is threaded through the inner wall of the insert plate until one end of the stud is threaded onto the inner wall of the lower sand mold. Thus, the lower and upper sand molds are securely installed, preventing loosening due to impact at the connection.

[0012] 2. In this solution, the connecting plate drives the rotating shaft to rotate on the inner wall of the concave block, so that one side of the connecting plate abuts against the outer wall of the lower sand mold. The sliding plate slides on the outer wall of the column until the outer wall of the sliding plate is installed on one side of the connecting plate.
