风扇塑料模具设计

摘  要
    PRO/E软件是美国PTC公司最新一代的机械设计，制造和系统管理软件，根据最新发布的消息，PRO/E软件用途广泛，它还包含了纠正正确和错误的功能，利用它可以进行几乎所有的生产设计和生产装配，包括NC制作过程，产品装配，产品设计，铸件设计，模具设计，组织分析，关于生产数据有限资金的管理分析，运用分析好的方向来定型等等。现在市场意识到许多大学，许多职业都涉及到基础软件，包括设计，机器维护，数据管理，电器设计，汽车，玩具行业对空间CAD/CAM的需要。在我们国家有许多大学和工厂得到广泛的运用，同时，局部地方在空间集成上运用此软件作为它的研究。
    使用PRO/E软件进行设计和其他软件一起使用会更快，利用此软件可以直接将三维，二维单元的草图进行相互转换，它有联合产品数据来管理零件功能和设计中的其他部分，用模型做工具设计，生产加工时可以随时进行数据修改，可以自动的反映在其他相关的每一个出现错误的时刻，PRO/E2001软件设计主要应用在空间部分，模具部分，NC操控部分，在这些方面有具体的实例，利用大量图表把每一部分的加工过程详细描述。

关键词：工业模具设计，三维实体外观，二维实体切面，建立基础切割文件，自动编程

Abstract:  The Pro/ ENGINEER is the United States PTC company new generation CAD/ CAE/ CAM that release it is often mighty that software, it is a software for gathering, right and wrong of its function, and make use of it can proceed spare parts the design, product assemble, few NC process, gold piece design, cast piece design, organization analysis, the analysis of limited dollar manage with product database, application analysis, direction shape better design etc..From now of the market come seeing the foundation software for many university for main profession for involving including the industry the design, machine, defending truely, making with data managing, electric circuit design, car, space CAD/ CAM for toy waiting, it at our country graduate school with factory inside getting the extensive application, at the same time, locally too in droves choosing using that software be used asing its research of its.
Usage the Pro/ ENGINEER proceeds development design, more want with other software quickly several times.Make use of that software can directly proceeds three units, two units sketch of convert mutually.It have the united product database to manage the function, and design in the spare parts, molding tool design, process themanufacturing to wait the any and bad stanza inside logarithms according to of modification, can all automatically reflect the other related and each the bad stanza, from but guarantee design with make to wait the unifying of each bad stanza data. Main portraiting of this design the Pro/ ENGINEER2001 design in the spare parts, molding tool design, NC operation method that process, and the solid example(Leaf round the molding tool process) make use ofed the large quantity's diagram slice the right each step to proceeds the detailed portraited.
Key words:  Industry molding tool design； Three units shape； Two units section；Establish the basis； Knife document； Automatic plait program
