The mold frame includes a front mold plate, a mosaic plate, a fixed plate and a rear mold plate which are arranged and installed in sequence, a clamping plate is provided between the mosaic plate and the fixed plate, and a pad is provided between the fixed plate and the rear mold plate. Among them, the mosaic plate is provided with a mosaic groove, and a detachable insert is installed inside the mosaic groove, and the insert is provided with a working hole. In the utility model, a set of universal mold frames can be used with multiple inserts to achieve the effect of multiple sets of molds, reducing the types and quantities of hardware molds required for die-cutting processing, thereby increasing the efficiency of die-cutting processing, saving the development and manufacturing costs and time of the mold, reducing the space occupied by the mold, and facilitating the transportation and storage of the mold.
