【正文】 effective low, the guarantee quality and so on a series of merits, is the present age industrial production important method and the craft development modern industry development and the technical level enhancement, is decided to a great extent by the mold industry level of the mold industry has bee one of national economy foundation industries. This design topic is the gear shaft coupling note mold, take counts the mold as the master line, has pleted the mold craft analysis, the structural design, the processing method, all processes which the mold assembly and so on a series of molds design the foundation curriculum which learned my university three years has all blended together, for example CAD, the mechanism several designed, the Office software, the numerical control programming and so before studied the knowledge to perform the review, and studied for the purpose of application, sharpened own ability. Obtained Liu Yuan splendidly in this design process, Mrs. the Zhao Gang attentive direction, expresses the heartfelt gratitude in this to them.
