The positioning clamping mechanism for mold processing can drive the insertion rod to move horizontally by setting a screw, a screw sleeve and a connecting rod, which is convenient for limiting or disassembling the mounting block. By setting a mounting groove, the mounting block can be preliminarily positioned. By setting the mounting box and the clamp body as a detachable structure, it is convenient to maintain the clamp body later, which solves the problem that the existing positioning clamping mechanism is inconvenient to repair during use.
