内容简介：

Pro / ENGINEER software in the plastic mold design,manufacture of application As Chinas automobile, motorcycle, household appliances, such as the rapid industrial development, industrial products in the shape to meet performance requirements, while becoming increasingly complex, and the manufacture of these products can not be separated from mold, which requires the manufacturing sector with the fastest die The speed, lowest cost and highest quality production to die. To achieve the above requirements, only enterprises Die The application of advanced management tools and CAD / CAM integrated manufacturing technology, to the fierce competition in the market in an invincible position. Pro / ENGINEER software Integrated Manufacturing Technology Die CAD / CAE / CAM system integration is key to the establishment of a single graphics database, the CAD, CAE, CAM, between the various units of automatic data transmission and conversion, CAM, CAE stage completely absorbed CAD phase of the 3D graphics and reduce Modeling the middle of the time and error; die on the use of computer performance, die structure, precision machining, metal molds in liquid in the flow of work and die in the process of distribution of temperature, etc. has repeatedly revised and optimized, problems will be found in official production Ago, greatly reducing system Die, Die improve processing accuracy. Pro / ENGINEER software using object-oriented database and the parameters of the unity of the modeling technology, with conceptual design, basic design and detailed design features for the integrated manufacturing molds provided an excellent platform. Pro / ENGINEER parallel projects in the application of technology in the mold Die-oriented type of production orders, a single production, manufacturing complex, calling for shorter delivery times. If the use of CAD, CAM cell technology manufacturing molds, precision manufacturing of low, long cycle, in order to solve these problems, we will be concurrent engineering technology to mold the manufacturing process. The so-called parallel project is a design engineer in product design three-dimensional parts to consider mold forming process, the factors affecting die life, and proof-reading, inspection, found the design process in advance of the error. Established products in the initial three-dimensional model, the design, manufacture and support of many sectors of the engineers at the same time die structure design, engineering Xiangtu design, mold-assisted analysis of CNC machine tools and processing the programming instructions, and each one of the engineers The changes made products can be automatically reflected in the other engineers there, greatly reducing design and NC programming time.In the actual production process, the application of Pro / ENGINEER software, structural design of the original mold mold cavity, the core of two-dimensional design ready mold cavity, the core design three-dimensional modeling programming instructions NC NC Serial processing technology by different routes to the design engineers at the same time, preparations of the parallel line, not only improve the accuracy of the die manufacturing, but also shorten the design and NC programming time by more than 40 percent. Parallel to the implementation of key projects to realize three-dimensional graphics data sharing parts, so that everyone engineers use graphical data is absolutely the same, and each engineer automatically reflect the changes made to other engineers there, the only guarantee of data And reliability. Pro / ENGINEER software with a single database, the parameters of the physical characteristics of modeling technology to achieve concurrent engineering technology to provide a reliable guarantee.Pro/ENGINEER软件在塑料模具设计、制造中的应用随着我国汽车、摩托车、家电等工业的迅速发展，工业产品的外形在满足性能要求的同时，变得越来越复杂，而这些产品的制造离不开模具，这就要求模具制造行业以最快的速度、最低的成本、最高的质量生产出模具。为了达到上述要求，模具企业只有 运用先进的管理手段和 CAD/CAM 集成制造技术，才能在激烈的市场竞争中立于不败之地。Pro/ENGINEER软件的集成制造技术模具CAD/CAE/CAM系统的集成关键是建立单一的图形数据库、在CAD、CAE、CAM，各单元之间实现数据的自动传递与转换，使CAM、CAE阶段完全吸收CAD阶段的三维图形，减少中间建模的时间和误差；借助计算机对模具性能、模具结构、加工精度、金属液体在模具中的流动情况及模具工作过程中的温度分布情况等进行反复修改和优化，将问题发现于正式生产前，大大缩短制模具时间，提高模具加工精度。Pro/ENGINEER 软件采用面向对象的统一数据库和参数化造型技术，具备概念设计、基础设计和详细设计的功能，为模具的集成制造提供了优良的平台。Pro/ENGINEER的并行工程技术在模具中应用模具是面向定单式的生产方式，属于单性生产，制造过程复杂，要求交货时间短。如果利用CAD、CAM单元技术制造模具，制造精度低、周期长，为了解决上述难题，我们将并行工程技术引入到模具制造过程中。所谓并行工程是设计工程师在进行产品三维零件设计时就考虑模具的成型工艺、影响模具寿命的因素，并进行校对、检查，预先发现设计过程的错误。在初步确立产品的三维模型后，设计、制造及辅助分析部门的多位工程师同时进行模具结构设计、工程详图设计、模具性能辅助分析及数控机床加工指令的编程，而且每一个工程师对产品所做的修改可自动反映到其他工程师那里，大大缩短设计、数控编程的时间。在实际生产过程中，应用Pro/ENGINEER软件，将原来模具结构设计模具
