Description
技术领域
一个方面大致涉及(且不限于)一种喷嘴定位绝缘体,一种具有喷嘴定位绝缘体的模制工具,和/或一种具有包括喷嘴定位绝缘体的模制工具系统的模制系统。
背景技术
第一种人造塑料是由Alexander PARKES于1851年在英国发明。他在1862年伦敦国际展览中将其公开展示,将其称作Parkesine材料。源自纤维素的Parkesine可以被加热、模制,且在冷却时保持其形状。然而,其制造昂贵、容易龟裂,并且高度易燃。1868年,美国发明家John Wesley HYATT开发了一种他命名为赛璐珞(Celluloid)的塑料材料,改进了PARKES的概念,使其可被加工成成品形式。HYATT在1872年取得第一种注塑模制机的专利权。其像较大的皮下注射器针头般工作,使用柱塞将塑料通过加热圆筒而注入模具中。在1940年代,因为第二次世界大战对廉价、大批量生产的产品创造了巨大需求,产业规模迅速扩大。1946年,美国发明家James Watson HENDRY制造了第一种螺杆式注塑机。这种机器也允许在注射之前混合材料,使得可在注射之前将有色或再生塑料添加到原始材料并彻底混合。在1970年代,HENDRY继续开发了第一种气体辅助注塑模制工艺。注塑模制机由料斗、注射压头或螺杆式柱塞和加热单元组成。其也被称为压力机,其保持组件在其中成型的模具。压力机由吨位额定,其表示机器可以施加的夹紧力的量。这个力在注射过程期间使模具保持闭合。吨位可从小于五吨至6000吨而变化,其中更高的数字使用在相对较少的制造作业中。总夹紧力的量由正在被模制的零件的投影面积所决定。对于每平方英寸的投影面积,这个投影面积乘以从二到八吨的夹紧力。作为经验法则,大多数产品可使用每平方英寸四吨或五吨。如果塑料材料非常生硬,那么可能需要更多注射压力来填充模具,因此需要更多夹紧吨位来使模具保持闭合。所需的力也可以由所使用的材料和零件的大小来决定,更大的零件需要更高夹紧力。用注塑模制,将颗粒状塑料通过重力从料斗送到加热筒中。随着颗粒通过螺杆式柱塞而缓慢向前移动,塑料被迫进入加热腔室中,并在此熔化。随着柱塞前进,熔化的塑料被迫通过抵靠模具而安放的喷嘴,允许其通过浇口和流道系统而进入模制腔。模具保持冷却,因此几乎只要模具被填充,塑料就会固化。模具总成或冲模是用于描述用于在模制中生产塑料零件的工具的术语。在生产数千个零件的大批量生产中使用模具总成。通常从硬化钢等等构造模具。在模制系统中使用热流道系统,其连同模具总成用于制造塑料制品。通常,热流道系统和模具总成被看作可从模制系统分开出售和供应的工具。
美国专利第6,890,473号公开一种用于注塑模制装置的热流道喷嘴的轴环,所述轴环包括具有从其第一端向内延伸的第一凸缘的大致圆筒形本体。提供第一凸缘以邻接喷嘴的喷嘴头和喷嘴本体的至少一部分。对准凸缘从大致圆筒形本体的内壁突出,并从第一凸缘分隔开。对准凸缘接触喷嘴本体以在注塑模制装置的组装期间限制轴环相对于喷嘴倾翻。

根据另一方面,提供一种具有喷嘴定位绝缘体(300)的模制工具系统(100)。
根据又另一方面,提供一种具有包括喷嘴定位绝缘体(300)的模制工具系统(100)的模制系统(200)。
在回顾非限制性实施方案的下文详细描述与附图后,非限制性实施方案的其它方面和特征现在对于所属领域技术人员将变得显而易见。
附图说明
将通过与附图结合时参考非限制性实施方案的下文详细描述而更完全地了解非限制性实施方案,其中:
图1描绘喷嘴定位绝缘体(300)、模制工具系统(100)和模制系统(200)的示意表示;和
图2A和图2B描绘喷嘴定位绝缘体(300)的其它示意表示。
图不一定按比例绘制,且可以通过虚线、图形表示和局部视图来图示。在某些例子中,可以省略对于理解实施方案不是必需的细节(和/或使其它细节难以理解的细节)。
具体实施方式
图1描绘喷嘴定位绝缘体(300)、模制工具系统(100)和模制系统(200)的示意表示(明确而言,截面图)。模制工具系统(100)可具有喷嘴定位绝缘体(300)。模制系统(200)可具有模制工具系统(100)。应了解,喷嘴定位绝缘体(300)、模制工具系统(100)和模制系统(200)可分开出售或由单个供应商提供。模制系统(200)例如包括压板总成(没有描绘,但是已知),其具有静止压板和可移动压板。模制工具系统由模制系统的压板总成支撑。喷嘴定位绝缘体(300)、模制工具系统(100)和模制系统(200)的每个可包括(但不限于)所属领域技术人员已知的组件,且将不在本文中描述这些已知组件;这些已知组件至少部分在以下参考书中描述(例如):(i)由OSSWALD/TURNG/GRAMANN著作的"Injection Molding Handbook″(ISBN:3-446-21669-2);(ii)由ROSATO AND ROSATO著作的"Injection Molding Handbook″(ISBN:0-412-99381-3),(iii)由JOHANNABER著作的"Injection Molding Systems"第三版(ISBN3-446-17733-7)和/或(iv)由BEAUMONT著作的"Runner and Gating Design Handbook″(ISBN1-446-22672-9)。应了解,出于本文件的目的,短语“包括(且不限于)”等效于词语“包括”。词语“包括”是连贯性短语或连贯词,其将专利权利要求的前序部分与定义本发明本身实际为何物的权利要求中阐述的特定元件相联系。过渡性短语用作权利要求的限制,其指示如果所指控的设备(等等)含有比专利的权利要求中更多或更少的元件,那么类似设备、方法或组合物是否侵犯专利。词语“包括”被看作开放式连贯,其是连贯的最宽泛形式,因为其没有将前序部分限制为权利要求中所确定的任何元件。
图2A和图2B描绘喷嘴定位绝缘体(300)的其它示意表示。喷嘴定位绝缘体(300)包括(且不限于):本体总成(302),其包括(且不限于)面向弹簧的表面(304)。面向弹簧的表面(304)包括(且不限于):(i)弹簧接触部分(306),和(ii)插入弹簧接触部分(306)之间的弹簧非接触部分(308)。如果是模制工具系统(100)具有喷嘴定位绝缘体(300)的情况,那么模制工具系统(100)可包括(且不限于):(i)模制喷嘴总成(102);和(ii)弹簧总成(112)。喷嘴定位绝缘体(300)的本体总成(302)可界定中央通道(309),其被构造来容纳模制喷嘴总成(102)。面向弹簧的表面(304)的弹簧接触部分(306)接触弹簧总成(112)。面向弹簧的表面(304)的弹簧非接触部分(308)可从弹簧总成(112)分离开,使得在弹簧总成(112)与弹簧非接触部分(308)之间没有接触或接触减少。弹簧非接触部分(308)减少(和/或消除至少部分)与弹簧总成(112)的表面接触,使得减少从模制喷嘴总成(102)通过喷嘴定位绝缘体(300)和弹簧总成(112)的热损失。模制喷嘴总成(102)可包括喷嘴外壳(106)和附接到喷嘴外壳(106)的加热器(104)。喷嘴定位绝缘体(300)可由钛制成,其在弹簧总成(112)可接触的外部平坦表面上具有凸起表面。弹簧接触部分(306)可称为定位在喷嘴定位绝缘体(300)的外部平坦表面上的凸起表面。弹簧非接触部分(308)插入弹簧接触部分(306)之间,使得弹簧接触部分(306)建立与弹簧总成(112)减小的表面接触面积,因此减少从模制喷嘴总成(102)通过喷嘴定位绝缘体(300)和弹簧总成(112)到歧管板(110)的热损失。模制工具系统(100)也可以包括已知组件,诸如但不限于:模具浇口(116)和杆(114)。喷嘴定位绝缘体(300)的优点在于在使用中减少从模制喷嘴总成(102)通过喷嘴定位绝缘体(300)和弹簧总成(112)到歧管板(110)的热传递。
