[0002] The mold frame is a semi-finished product of the mold, which is composed of various steel plates and parts. It can be said to be the skeleton of the entire mold. The mold frame is the support of the mold and is an inseparable part of the mold.

[0003] For example, the Chinese authorized patent with announcement number CN217493988U (a positioning and fixing device for mold frame processing): includes a fixed platform, a positioning mechanism and a first boss, wherein the first boss is fixedly mounted on the upper surface of the fixed platform, and the positioning mechanism is arranged inside the first boss. The utility model places the mold frame on the upper surface of the first boss and the second boss, rotates the handwheel to drive the threaded rod to rotate, and the threaded rod pushes the moving block to move to the right along the slide groove. The first positioning plate on the upper surface of the moving block clamps the mold frame, so that the mold frame is fixed between the first positioning plate and the second positioning plate, thereby achieving the positioning effect of the mold frame. Then, when the corner cylinder is started, the lower pressure plate presses down the upper surface of the mold frame, so that the mold frame is completely fixed. The structure is simple, easy for operators to operate, improves the positioning effect of the fixing device, and avoids the phenomenon of position displacement of the mold frame when subjected to large processing force.

[0004] However, the existing method of fixing the mold frame through a corner cylinder and clamping has a limited clamping distance, poor applicability to mold frames of different sizes, and the corner cylinder needs to be kept in operation for a long time, which seriously wastes resources. In addition, the power needs to be turned off when moving, and if the fixation becomes loose, it needs to be re-fixed, which is time-consuming and labor-intensive. Therefore, it does not meet the existing needs. In this regard, we propose a positioning and fixing device for mold frame processing. Utility Model Content
