Sign fork to slice a blunt bore mold design

 【Abstract】Blunt press a molding tool to apply in the physically industrial production extensive.At traditional of industry production in, the worker produces of the labor strength is big, labor have great capacity, seriously influence production the exaltation of efficiency.Along with nowadays technological development,The use of molding tool has already more and more caused the value of people, but is in great quantities applied to industrial production in the industrial production in.Is blunt to press the auto of molding tool to send to anticipate a technique to also throw in actual production, hurtle to press a molding tool can consumedly of exaltation labor production efficiency, ease worker's burden, have an important technique progress meaning and economic value.This text opposition fork sliced a head to hurtle to press technical classification, characteristics and development direction to be Chien to slightly outline;Discuss blunt press the formation principle of spare parts and basic molding tool of structure and sport process and it design principle, to blunt pressed a molding tool to carry on to design, this text introduction of molding tool solid example the structure is in brief practical, use convenience credibility, have a certain reference function to large numbers of quantity productions that is similar to a work piece.
