因人们日常生活所用的制品和各种机械零件,在成型中多数是通过模具来制成品,所以模具制造业已成为一个大行业。
在高分子材料加工领域中,用于塑料制品成形的模具,称为塑料成形模具,简称塑料模.塑料模优化设计,是当代高分子材料加工领域中的重大课题。
塑料制品已在工业、农业、国防和日常生活等方面获得广泛应用。
为了生产这些塑料制品必须设计相应的塑料模具。
在塑料材料、制品设计及加工工艺确定以后,塑料模具设计对制品质量与产量,就决定性的影响。
首先,模腔形状、流道尺寸、表面粗糙度、分型面、进浇与排气位置选择、脱模方式以及定型方法的确定等,均对制品(或型材)尺寸精度形状精度以及塑件的物理性能、内应力大小、表观质量与内在质量等,起着十分重要的影响。
其次,在塑件加工过程中,塑料模结构的合理性,对操作的难易程度,具有重要的影响。
再次,塑料模对塑件成本也有相当大的影响,除简易模外,一般来说制模费用是十分昂贵的,大型塑料模更是如此。
现代塑料制品生产中,合理的加工工艺、高效的设备和先进的模具,被誉为塑料制品成型技术的“三大支柱”。
尤其是加工工艺要求、塑件使用要求、塑件外观要求,起着无可替代的作用。
高效全自动化设备,也只有装上能自动化生产的模具,才能发挥其应有的效能。
此外,塑件生产与更新均以模具制造和更新为前提。
塑料摸是塑料制品生产的基础之深刻含意,正日益为人们理解和掌握。
当塑料制品及其成形设备被确定后,塑件质量的优劣及生产效率的高低,模具因素约占80%。
由此可知,推动模具技术的进步应是不容缓的策略。
尤其大型塑料模的设计与制造水平,标志一个国家工业化的发展程度。
1.2 我国塑料模现状在模具方面,我国模具总量虽已位居世界第三,但设计制造水平总体上比德、美、日、法、意等发达国家落后许多,模具商品化和标准化程度比国际水平低许多。
摘要本课题主要是智能玩具枪膛塑件的注射模具设计,该模具材料为具有良好的综合性能的ABS。
通过对塑件进行工艺的分析和比较,以及浇口位置方案的比较,最终设计出一副注射模。
该设计从产品结构工艺性、具体模具结构出发,对模具的浇注系统、模具成型部分的结构、顶出系统、冷却系统、注射机的选择及有关参数的校核、抽芯机构都有详细的设计,同时并简单的编制了模具的部分零件的数控加工程序。
根据题目的要求,其主要任务是智能玩具枪膛塑件注射模具的设计,也就是设计一副模具来生产塑件产品,以实现自动化提高产量。
针对塑件的具体结构,该模具是潜伏式浇口瓣合模注射模具。
整个设计过程表明模具能够达到此塑件所要求的加工工艺。

检测仪手柄平移式双色注塑模具设计张小清【期刊名称】《工程塑料应用》【年(卷),期】2018(046)003【摘要】Aiming at the needs of a double color injection for the detector handle,the parallel moving hot runner double color injection mould was designed. The layout of mould cavity was composed of two cores and three cavities,that is,the combination of two parallel cores and two adjacent cavities in three parallel cavities was realized through the movement of the two parallel cores, the purpose of double color injection moulding was achieved by constantly changing the cavity for injection moulding. To meet the injection moulding requirements of the mould,the vertical injection moulding barrel was installed in the traditional single barrel hor-izontal injection moulding machine, a new injection moulding machine was obtained with two mutually perpendicular barrels. The injection moulding machine has the low transformation cost and the monochrome and double color injection moulding function. It has strong innovation and practical application value. Compared to the traditional rotating double color injection moulding method, this dual color moulding method saves the cost of the design and manufacture for a pair of moulds. The mould structure is novel,the innovation is strong,the engineering application value is high.%针对某检测仪手柄双色注塑的需要,设计了一种动模平行移动式热流道双色注塑模具,模具型腔布局采用两型芯与三型腔相配合的布局方式,即通过两个并列式型芯的移动实现与三个并列式型腔中的相邻两个进行组合,不断变换型腔进行注塑达到双色注塑的目的;为配合模具的注塑需要,在传统的单炮筒卧式注塑机结构基础上加装了立式注塑炮筒,改造成两个炮筒相互垂直的新型注塑机,注塑机的改造成本较低,具备单色、双色注塑功能,有较强的创新性和实际应用价值;相比于传统的旋转式双色注塑成型方法,该双色成型方法节省了一副模具的设计制造成本,模具结构新颖,创新性强,工程应用价值高.【总页数】6页(P76-81)【作者】张小清【作者单位】广东省技师学院,广东惠州 516100【正文语种】中文【中图分类】TG386.3【相关文献】1.动模平移式多材质顺序注塑模具设计 [J], 张惠敏;杨德;韩雷雷2.机械接触式薄壁键帽注塑件双色注塑模具设计 [J], 梅益;杨幸雨;曲玥明3.玩具手柄双色注塑模具设计 [J], 陆建军;徐伟4.汽车挡风玻璃装饰条对射式双色注塑模具设计 [J], 刘鑫; 郭恒亚; 黄明5.扫描仪双色手柄注塑模具设计 [J], 张春彬; 范红杰; 邹积洋因版权原因,仅展示原文概要,查看原文内容请购买。
