1、 塑料注塑模具并行设计 Assist.Prof.Dr. A. YAYLA /Prof.Dr. Pa a YAYLA 摘要 塑料制品制造业近年迅速成长。其中最受欢迎的制作过程是注塑塑料零件。注塑模具的设计对产品质量和效率的产品加工非常重要。模具公司想保持竞争优势 ,就必须缩短模具设计和制造的周期。 模具是工业的一个重要支持行业，在产品开发过程中作为一个重要产品设计师和制造商之间的联系。产品开发经历了从传统的串行开发设计制造到有组织的并行设计和制造过程中 ,被认为是在非常早期的阶段的设计。并行工程的 概念 (CE)不再是新的 ,但它仍然是适用于当今的相关环境。团队合作精神、管理参与、总体设计过程和

2、整合 IT 工具仍然是并行工程的本质。 CE 过程的应用设计的注射过程包括同时考虑塑件设计、模具设计和注塑成型机的选择、生产调度和成本中尽快设计阶段。 介绍了注射模具的基本结构设计。在该系统的基础上 ,模具设计公司分析注塑模具设计过程。该注射模设计系统包括模具设计过程及模具知识管理。最后的原则概述了塑料注射模并行工程过程并对其原理应用到设计。 关键词 :塑料注射模设计、并行工程、计算机辅助工程、成型条件、塑料注塑、流动 模拟 1、简介 注塑模具总是昂贵的 ,不幸的是没有模具就不可能生产模具制品。每一个模具制造商都有他 /她自己的方法来设计模具 ,有许多不同的设计与建造模具。当然最关键的参数之一

3、 ,要考虑到模具设计阶段是大量的计算、注射的方法 ,浇注的的方法、研究注射成型机容量和特点。模具的成本、模具的质量和制件质量是分不开的 在针对今天的计算机辅助充型模拟软件包能准确地预测任何部分充填模式环境中。这允许快速模拟实习 ,帮助找到模具的最佳位置。工程师可以在电脑上执行成型试验前完成零件设计。工程师可以预测过程系统设计和加工 窗口 ,并能获得信息累积所带来的影响 ,如部分过程变量影响性能、成本、外观等。 2、注射成型法 注塑成型是最有效的方法之一 ,将塑料最好的一面呈现。这是普遍用于制造复杂的制件 ,优点是简单、经济、准确与少浪费。塑料零件的批量生产主要采用模具。产品设计制造过程包括模具

4、的结构必须经过外观评价和结构优化。当设计师创造注射模具组件时，他们面临一个巨大的多种选择，并行工程需要一个工程师考虑制产品在发展阶段时的过程设计。一个好的产品设计为了满足市场其制造过程是不可能太贵的。CAD/CAM 整合了过程仿真、快速成形制造能减 少风险 ,进一步提高产品开发的有效性。 3、注塑模具设计重要的计算机辅助 注射模具设计任务是相当复杂的。计算机辅助工程 (CAE)分析工具提供了巨大的优势让设计工程师考虑几乎所有模具、注塑参数没有真正利用的地方。在可能性的设计、理念设计师，给工程师们机会去消除潜在的问题 ,开始真正的生产。此外 ,在虚拟环境中 ,设计师可以快速而方便地评估特定的成型

5、参数敏感性的质量和生产最终产品。所有这些分析工具使所有模具设计将在一天甚至数小时完成 ,而不需要几周或几个月来做真正的实验反复试验。 CAE 用于早期设计的部分 ,模具和注 塑模具参数、节约成本是实质功能不仅是最好的部分 ,而且还能节省和缩短开发产品推向市场的时 间间。 CONCURRENT DESIGN OF PLASTICS INJECTION MOULDS Assist.Prof.Dr. A.

6、pidly in recent years. One of the most popular processes for making plastic parts is injection moulding. The design of injection mould is critically important to product quality and efficient product processing. Mould-making companies, who wish to maintain the competitive edge, desire to shorten bot

7、h design and manufacturing leading times of the by applying a systematic mould design process. The mould industry is an important support industry during the product development process, serving as an important link between the product designer and manufacturer. Product development has changed from

8、the traditional serial process of design, followed by manufacture, to a more organized concurrent process where design and manufacture are considered at a very early stage of design. The concept of concurrent engineering (CE) is no longer new and yet it is still applicable and relevant in todays man

9、uf acturing environment. Team working spirit, management involvement, total design process and integration of IT tools are still the essence of CE. The application of The CE process to the design of an injection process involves the simultaneous consideration of plastic part design, mould design and

10、 injection moulding machine selection, production scheduling and cost as early as possible in the design stage. This paper presents the basic structure of an injection mould design. The basis of this system arises from an analysis of the injection mould design process for mould design companies. Thi

11、s injection mould design system covers both the mould design process and mould knowledge management. Finally the principle of concurrent engineering process is outlined and then its principle is applied to the design of a plastic injection mould. Keywords :Plastic injection mould design, Concurrent

Introduction Injection moulds are always expensive to make, unfortunately without a mould it can not be possible ho have a moulded product. Every mould maker has his/her own approach to desig

13、n a mould and there are many different ways of designing and building a mould. Surely one of the most critical parameters to be considered in the design stage of the mould is the number of cavities, methods of injection, types of runners, methods of gating, methods of ejection, capacity and features

14、 of the injection moulding machines. Mould cost, mould quality and cost of mould product are inseparable. In todays completive environment, computer aided mould filling simulation packages can accurately predict the fill patterns of any part. This allows for quick simulations of gate placements and

15、helps finding the optimal location. Engineers can perform moulding trials on the computer before the part design is completed. Process engineers can systematically predict a design and process window, and can obtain information about the cumulative effect of the process variables that influence part performance, cost, and appearance. 2.
