Abstract
一种注入成型用整体浇口和腔嵌入件，此嵌入件具有由此通过而延伸、用以安放加热喷嘴和形成腔的一部分的浇口。浇口和腔嵌入件具有一条通过其而延伸的冷却流体通道。浇口和腔嵌入件具有一个内部分、一个外部分和一个浇口部分。与冷却流体接触的内、外部分由诸如不锈钢的抗腐蚀材料制成。与冷却流体不接触的浇口部分由诸如H13工具钢或碳化钨的更耐磨和更抗热冲击的材料制成。
Description
本发明一般说来涉及注入成型装置，更具体说来，涉及由三件整体连接在一起的部件构成的整体浇口和腔嵌入件。
一些具有浇口和腔嵌入件的注入成型装置已广为人知，浇口和腔嵌入件具有冷却流体流动通道，它们构成腔的一部分，而浇口则通过腔延伸以将熔料从加热注嘴输送至腔中。例如，1986年11月11日授予Bright等人的美国专利4622001公开了一种由螺栓连接在一起的两件单独部件制成的浇口和腔嵌入件。近来，1995年8月22日授予Gellert的美国专利5443381公开了一种由内、外部件或部分构成的整体浇口和腔嵌入件，这两个部分与一条延伸通过其间的冷却流体流动通道整体地连接在一起。外部件由诸如H13或不锈钢的合适钢材制成，而内部件则由导热更好和抗腐蚀的铍—镍合金制成。
虽然前述结构对许多应用来说是令人满意的，但在某些条件下模制某些材料时，发现在浇口区域有过度磨损。
因此，本发明的一个目的是通过提出整体可被冷却的浇口和腔嵌入件以便至少部分克服现有技术的缺陷，这些浇口和腔嵌入件具有与冷却流体接触、由抗腐蚀材料制成的内、外部分和一个由更为抗磨损的材料制成的浇口部分，浇口通过它而延伸。
为此目的，根据其一个方面，本发明提出了一种安装在模具中加热注嘴和腔之间的注入成型用整体浇口和腔嵌入件。浇口和腔嵌入件具有一个凹陷以安放注嘴的后内表面，和一个形成腔的后表面的一部分的前表面。浇口从后表面沿中心通过浇口和腔嵌入件延伸至前表面以便将熔料从注嘴输送至腔中。冷却流体流动通道通过浇口和腔嵌入件从冷却流体入口延伸至冷却流体出口。浇口和腔嵌入件具有整体连接在一起的一个内部分、一个外部分和一个浇口部分。内部分装配在外部分中以便在它们之间形成冷却流体流动通道。浇口部分装配在内、外部分中的至少一个部分中，并具有通过其而延伸的浇口。内、外部分由抗腐蚀材料制成，而浇口部分则由较制成内、外部分的材料更为耐磨损和导热更好的材料制成。
本发明的其它目的和优点将通过下述参照附图的说明变得更为清晰。

图5是浇口和腔嵌入件的内部分的等量图，它展示围绕此处的冷却流体流动的方式；以及
图6是本发明另一实施例提出的一种浇口和腔嵌入件的截面图。
首先参看图1，它是多腔注入成型系统或装置的一部分的截面图，展示了本发明的一个实施例提出的整体浇口和腔嵌入件10。若干细长的加热注嘴12安装在模具14中，并用螺栓20将它们的后端16紧固至钢质熔料分配总管18上。虽然根据不同应用，模具件14可具有很多的板，但此处为说明方便起见，只展示了由螺栓26固定在一起的一块总管板22和一块压紧板24，以及一块腔支承板28和一块腔板30。
每一浇口和腔嵌入件10包括一个形成注嘴井的凹陷的后内表面32、一个在此实施例中形成腔38的部分后表面36的前表面34，以及一个浇口40，此浇口40从注嘴井32沿中心由此通过延伸至前表面34，用以将熔料从注嘴12输送至腔38。浇口和腔嵌入件10装配在一个通过腔支承板28而延伸的开口42、以及一个通过腔板30而延伸的对准的开口44中，并以其后端46紧倚总管板22。一条双螺旋冷却流体通道48通过浇口和腔嵌入件10而延伸，并通过冷却流体入口和出口导管50、52连接至诸如水的合适冷却流体源(未示出)。定位销钉54从浇口和腔嵌入件10伸出进入腔支承板28，以确保冷却流体通道48适当地与入口和出口导管50、52对准。
熔料通道56在熔料分配总管18中分支，并通过每一加热注嘴12中的中心熔料孔58延伸至通向腔38的浇口40。熔料分配总管18具有一个由定位环62围绕的圆柱形入口部分60，并由一件组合式电加热元件64进行加热。熔料分配总管18通过一个中心总管定位器66和若干压力盘68安装在总管板22与压紧板24之间，压力盘68在加热总管18与围绕着的模具14之间形成一个隔热空气空间70，模具14通过泵送一种诸如水的冷却流体通过冷却导管72而被冷却。
每一注嘴12具有一个围绕中心熔料孔58而延伸的组合式电加热元件74。在此实施例中，每一加热注嘴12还具有一个带有向前指向尖端78的尖端嵌入件76，它由一个螺纹夹持套管80固定在位。夹持套管80紧倚和定位浇口和腔嵌入件10，以使尖端嵌入件76的尖端78精确地对准通向腔38的浇口40。加热注嘴12还在其后端16附近有一个法兰部分82，它装配在总管板22中的圆形底座84中。这将使加热注嘴12定位，并具有一个隔热空气空间86，该隔热空气空间86在加热注嘴12的外表面88与浇口和腔嵌入件10的后内表面32之间延伸。
参看图2-5以详细说明此实施例提出的浇口和腔嵌入件10及其制作方法。如图2所示，浇口和腔嵌入件10由三个部件或三个部分，即一个中空内部分90、一个中空外部分92和一个浇口部分94构成。内部分90具有脊状外表面96，它装配在外部分92中以便在它们之间形成冷却流体通道48。如图5中箭头所示，冷却流体通道48通过一条双螺旋从一个与冷却流体入口导管50对准的入口98向前延伸，围绕内部分90的前端110，然后通过双螺旋返回至与冷却流体出口导管52对准的出口102。沿脊状外表面96施加了一条镍合金焊膏的焊道104，然后将内部分90插入至外部分92中。在浇口部分94上也施加了一条镍合金焊膏104的焊道105，然后将其插入至位于内、外部分90、92的前端110、112的相邻的开口106、108中。与流过双螺旋型通道48的冷却水接触的内、外部分90、92由诸如不锈钢的一种或多种抗腐蚀材料制成，而浇口40通过其中而延伸的浇口部分94则由更耐磨和抗热冲击及导热性更好的材料，诸如H13工具钢或碳化钨制成。
组装的内、外部分90、92及浇口部分94在真空炉中逐渐加热至镍合金熔点以上的约1925°F的温度。在炉子加热时，它被抽至较高的真空以基本除去所有氧气，然后用诸如氩或氮的惰性气体进行部分再充气。当达到镍合金的熔点时，它熔化，并由于毛细作用而在浇口部分94及内、外部分90、92之间流动，从而将这三部分整体焊接在一起，以形成图3所示的整体浇口和腔嵌入件10。采用在真空炉中将它们焊接在一起的方法使它们之间形成金相结合，从而使浇口和腔嵌入件10的强度达到最高，并防止冷却水渗漏。将浇口和腔嵌入件10从真空炉中取出后，将它机械加工至如图4所示的功能尺寸和外形。
在使用中，首先将注入成型装置或系统按图1所示加以组装。虽然为说明方便起见只展示了一个单个腔38，但显然，根据不同应用，通常熔料分配总管18可有延伸至多个腔38的多条熔料通道分支。对总管18和注嘴12中的加热元件64、74通电以便将它们加热至预定的运行温度。水或其它合适的冷却流体以预定温度被输送至双螺旋冷却流体通道48和冷却导管72以冷却浇口和腔嵌入件10及模具12。如图可见，流过螺旋通道48的冷却水只接触由抗腐蚀材料制成的浇口和腔嵌入件10的内、外部分90、92，而不接触由更耐磨和抗热冲击材料制成的浇口部分94。然后以预定周期按照常规方法将热的加压熔料从模制机(未示出)通过中心入口114注入熔料通道56。熔料通过加热注嘴12中的熔料孔58流动进入腔38。当腔38被充满时，注入压力瞬间升至峰值，然后释放。在一个短暂的冷却期后，模具14打开进行出坯。出坯后，模具14闭合，重新施加注入压力以重新填充腔38。此循环以一定的频率不断重复，而频率决定于腔38的尺寸及模制材料的类型。
现在参看图6以说明本发明的另一实施例。在此实施例中，浇口和腔嵌入件10不是细长的，而冷却流体通道48则如与此同时提交的名为“注入成型用可被冷却的浇口和腔嵌入件”的申请No.2,228,458本申请人的加大拿专利申请中所描述的那样既向前和后又向内和外延伸，而不像上述实施例中的沿螺旋线延伸。但是它具有由抗腐蚀材料制成的内、外部分90、92及由更耐磨和抗热冲击材料制成的浇口部分94，并由上述相同方法制成以及同样的使用。
虽然注入成型用三部件浇口和腔嵌入件的说明是根据本发明的最佳实施例进行的，但显然，在不偏离本技术领域的一般技术人员所理解和由下述权利要求限定的范围的情况下，本发明还可能有多种其它修改方案。
