Abstract

In this design introduced the transmission covers the punch holes the ramming craft analysis, the craft plan formulation, arranges the specimen map design, the always ramming strength computation and the center of pressure computation, the cutting edge size computation, the spring, the rubber computation and selects, the raised mold, the concave mold or the convex-concave mold structural design and all that die the components structural design, draws up the mold assembly drawing and the work detail drawing, the compilation design instruction booklet, fills in the ramming craft card and the work components machine-finishing technological process card, raised pays attention to, the concave mold coordinate processing. The calculation concerning craft parameter, such as: Hurtle to cut the dint and unload the calculation of anticipate the dint. The blunt bore  molding tool structure designs the medium  calculation and the design etc. concerning not standard piece.
Key words: Raised mold; Concave mold; Plan; Installation;
