注塑机模板加工论文

需要帮忙吗？在读研究生指导你写作

呵呵你做的这个论文，我毕业的时候我也做过你看看是不是这份，需要我给你发过去。塑料工业是当今世界上增长最快的工业门类之一，而注塑模具是其中发展较快的种类，因此，研究注塑模具对了解塑料产品的生产过程和提高产品质量有很大意义。本论文介绍了注射成型的基本原理，特别是单分型面注射模具的结构与工作原理，对注塑产品提出了基本的设计原则，详细介绍了冷流道注射模具浇注系统、温度调节系统和顶出系统的设计过程，并对模具强度要求做了说明。设计成型零部件以及设计合理的推出机构。对设计进行验证主要是对注射机的相关重要参数进行验证，包括模具闭合厚度、模具安装尺寸、模具开模行程、注射机的锁模力等。在校验合格后，进行成型零件加工工艺过程的制定，既要保证塑件的质量，又要兼顾经济性。最后则是模具的装配环节，包括制定装配步骤、明确注意事项等。通过本设计，可以对注塑模具有一个初步的认识，注意到设计中的某些细节问题，了解模具结构及工作原理；通过对AutoCAD的学习，可以建立较简单零件的零件库，从而有效的提高工作效率。关键词：生产工艺 注射模 成型零件 装配 塑料模具 分型面AbstractPlastic industry is grows now one of quickest industry classes in the world, 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 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; Introduced in detail the cold flow channel injection evil spirit mold pours the system, the temperature control system and goes against the system the design process, and has given the explanation to the mold intensity request. Design shaped parts，reasonable drawing mechanism and so on．The design should be certification．Primarily related to the injection machine of important parameters for the certification including die close thickness sizes，the name distance，injection machine of the die draw force and so on．After Qualified in check，the molding parts machining process design must ensure that the quality of Supervision taking into account the economy．Final assembly is part of the mold，which including the design of assembly steps，clear proceeding required attention．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; Through to the PROGRAM study, may establish the simple components the components storehouse, thus effective enhancement working word: Manufacture process Injection mold Shaped parts The plastic mold Divides the profile1 绪 论 我国塑料模具工业的发展现状及特点�我国塑料模工业从起步到现在，历经半个多世纪，有了很大发展，模具水平有了较大提高。在大型模具方面已能生产48英寸大屏幕彩电塑壳注射模具、 大容量洗衣机全套塑料模具以及汽车保险杠和整体仪表板等塑料模具，精密塑料模具方面，已能生产照相机塑料件模具、多型腔小模数齿轮模具及塑封模具。如天津津荣天和机电有限公司和烟台北极星Ⅰ.K模具有限公司制造多腔VCD和DVD齿轮模具，所生产的这类齿轮塑件的尺寸精度、同轴度、跳动等要求都达到了国外同类产品的水平，而且还采用最新的齿轮设计软件，纠正了由于成型收缩造成齿形误差，达到了标准渐开线齿形要求。还能生产厚度仅为的一模两腔的航空杯模具和难度较高的塑料门窗挤出模等等。注塑模型腔制造精度可达～，表面粗糙度μm，模具质量、寿命明显提高了，非淬火钢模寿命可达10～30万次，淬火钢模达50～1000万次，交货期较以前缩短，但和国外相比仍有较大差距。成型工艺方面，多材质塑料成型模、高效多色注射模、镶件互换结构和抽芯脱模机构的创新方面也取得较大进展。气体辅助注射成型技术的使用更趋成熟，如青岛海信模具有限公司、天津通信广播公司模具厂等厂家成功地在29～34英寸电视机外壳以及一些厚壁零件的模具上运用气辅技术，一些厂家还使用了C-MOLD气辅软件，取得较好的效果。如上海新普雷斯等公司就能为用户提供气辅成型设备及技术。热流道模具开始推广，有的厂采用率达20%以上，一般采用内热式或外热式热流道装置，少数单位采用具有世界先进水平的高难度针阀式热流道模具。但总体上热流道的采用率达不到10%，与国外的50%～80%相比，差距较大。
