Description

本实用新型涉及一种制造塑料颗粒的挤压机造粒模板。
目前,塑料挤压机的造粒模板类型较多,除了几何尺寸不同外,它们的结构设计也截然不同。日本制钢所生产的造粒模板,其热介质通道为一个环形空腔,物料出口面上,喷焊有一层1.5~2.0毫米厚的合金层,构成造粒带的耐磨面。出料孔道为管道形,通过外壁与模体上、下面焊接在一起。这种造粒模板的造粒带耐磨面是采用喷焊方法形成的一个整体面,当切刀划痕后,就需要通过研磨来修复。但是,由于喷焊工艺限制,使形成的耐磨面不能太厚,所以这种耐磨面,一般只能研磨1~2次便不可再修复。另外,造粒板的出料孔是一些小管焊接在模体上,其孔道背面容易漏汽,而且不可修复,造成模板使用寿命较短。
本实用新型的目的是,改变造粒带耐磨面的结构和出料孔的构形及加工工艺,提高造粒带耐磨面的硬度和造粒带、出料孔的可修复性,达到延长塑料造粒模板的使用寿命。
本实用新型构成的要点是,物料孔道采用园柱形不锈钢棒,先在两端予钻一个定位、定向孔后,一端与物料孔道管板焊接在一起,另一端与模体背面焊接在一起,然后再钻通钢棒,其通道可钻成25°~35°锥形角孔;造粒带为一复合组合式,选用4.5~6.0毫米厚的不锈钢环形板作为造粒带盖板,盖板上的透孔内装配有带孔的硬质合金环和不带孔的硬质合金柱,组成造粒带耐磨面,再用定位的方法与物料孔道管板上的出料孔对正后钎焊为一体。
下面结合附图详细叙述本实用新型一个实施例。
图1是本实用新型的俯视图;
图2是图1中A-A的剖面图;
图3是图2中A的放大图。
图1、图2中描述的塑料挤压机造粒模板,在模体(12)的外园盘处有一个凸台面(19),均布有12个,且位于同一园周上,用于与切粒机连接的紧固孔(1)。靠环形造粒带盖板(7)的内、外处分别有一个环形面(16)、(17),在环形面(16)、(17),且位于同一园周上,分别均布有16个、6个,供与挤压机紧固的螺栓孔(3)、(5),并且每两个螺栓孔(3)或(5)间,都有一个供紧固盖板的螺孔(2);在模板正面对称切面处有2个,用于拆卸模板的顶丝孔(18)。
在模板模面上的环形面(16)、(17)间,有一个环形凸台为造粒带盖板(7),选用厚度为6毫米的不锈钢板,在其面上有五排交错排列的,其中中间三排,孔径为∮6的透孔,其内装配有∮6×6的带孔钨钴合金环(9),最外一排和最内一排,孔径是∮4的透孔,其内装配有∮4×6的不带孔的钨钴合金柱(10)。造粒带盖板(7)在与物料孔道柱(4)对正后,与物料孔道管板(11)焊接为一体,构成造粒模板的造粒带。
造粒带下面为一环形空腔气室(8),与气室(8)相沟通,位于模体(12)两侧壁面上有一对相对称的热介质进出气道孔(6);物料孔道(4),选用∮8的不锈钢棒,在予钻定位、定向孔后,穿过气室(8)与模体(12)背面和物料孔道管板(11)焊接为一体,再钻通物料孔道柱(4)。其物料孔道柱柱(4)内孔为30°锥形角孔。
模板(12)背面与挤压机接触处为一平面,在背面出料口内、外侧有一个用于定位和密封的内环形止口(13),外环形止口(14),外园盘凸台面内边缘处有一个环形定位止口(15),使模板与挤压机保持一定的位置。
本实用新型与已有技术相比,其优点是造粒带改变为复合组合式,不仅能提高了造粒带的耐磨性,而且具有可修复性,使造粒模板的使用寿命大大地延长。已有技术的造粒板,一般在使用3~6个月,便出现切刀划痕,就需要研磨一次,而且由于硬度层比较薄,当研磨1~2次后,便不可再修复。整个模板使用寿命为1~2年。本实用新型的造粒板,一般情况下使用一年后研磨一次,可研磨3~5次,模板使用寿命为3~5年。另外出料孔道与模体的组装工艺改进,使其焊接后牢固可靠,不易泄漏。而且一旦发生泄漏还可以进行修复。
