ABSTRACT
This design carried on has flushed circle hole, flushes the trough, falls the material continual mold the design. In the article has briefly outlined the ramming mold at present development condition and the tendency. Has carried on the detailed craft analysis and the craft plan determination to the product. According to general step which the ramming mold designs, calculated and has designed on this set of molds main spare part, for example: The raised mold, the concave mold, the raised mold dead plate, the backing strip, the concave mold dead plate, unloads, leads the ruler, keeps off the material to sell, to lead is selling and so on. The mold frame uses the standard mold frame, has selected the appropriate ramming equipment. In the design has carried on the essential examination computation to the work components and the press specification. In addition, this mold uses the beginning with to keep off the material to sell with the circular keeps off the material. the concave mold and falls the material concave mold to use the overall dead plate to be fixed. Fell the material raised mold internal installation to have leads is selling, had guaranteed on the work piece the hole and the contour relative position was accurate, increased the processing precision. So designs the structure may guarantee the mold work movement to be reliable and the ramming product mass production request.
Key word: Continual mold; Ramming mold; Standard mold frame; Ramming equipment; Examination; flush hole; Falls the material .
