【正文】 facturing and Automation Author: Liu shuntao Tutor: Du xibo Abstract: plastic industry is in the world grows now one of quickest industry classes,but casts the mold is development quick type,therefore,the research casts the mold to understand the plastic product the production process and improves the product quality to have the very big significance. This design introduced the injection takes shape the basic principle,specially single is divided the profile to inject the mold the structure and the principle of work,to cast the product to propose the basic principle of design。 Finally introduced now in the world the most popular three dimensional CAD/CAM system standard software PRO/Engineer’s EMX module,and led the wrap to the guide pillar to carry on the parameterization design. Through this design,may to cast the mold to have a preliminary understanding， notes in the design certain detail question, understands the mold structure and the principle of work。 the parameterization。 divides the profile 河南理工大學(xué)畢業(yè)設(shè)計(jì)（論文） 3 前 言 ......................................................................................................... 1 1 模具簡介 .................................................................................................. 2 模具工業(yè)在國民經(jīng)濟(jì)中的地位 .......................................................... 2 各種模具的分類和占有量 ................................................................. 3 我國模具工業(yè)的現(xiàn)狀 ........................................................................ 4 世界五大塑料生產(chǎn)國的產(chǎn)能狀況 ....................................................... 5 我國模具技術(shù)的現(xiàn)狀及發(fā)展趨勢 ....................................................... 7 2 注射?？尚行苑治?
