The utility model provides an intelligent mold machining system. The system comprises a master control device and a plurality of intelligent processing devices, the master control device can receive an input mold 3D drawing file, color coating operation on a to-be-processed part of a mold in the mold 3D drawing file is executed according to user input information, and the mold 3D drawing file subjected to the color coating operation is issued to the corresponding intelligent processing device. A receiver of the intelligent processing equipment receives the mold 3D image file which is subjectedto the coloring operation and is issued by the master control equipment; and the processing controller determines the color corresponding to the processing mode of the processing controller accordingto the mould 3D drawing file subjected to the coloring operation, positions the to-be-processed part of the mould mounted on the processing controller by utilizing the determined color, and further processes the positioned to-be-processed part of the mould by utilizing the processing table. Here, the processing modes of the to-be-processed parts of the mold are different, and the colors of the to-be-processed parts are also different. According to the embodiment of the utility model, the problems of missing machining, repeated machining and abnormal mold machining can be effectively avoided.
