Several methods are used to force or inject the melted plastic into the mold. The most commonly used system in the larger machines is the in-line reciprocating screw, as shown in Figure 1-1 . The screw acts as a combination injection and plasticizing unit. As the plastic is fed to the rotating screw, it passes through three zones as shown: feed, compression, and metering. After the feed zone, the screw-flight depth is gradually reduced, forcing the plastic to compress. The work is converted to heat by shearing the plastic, making it a semifluid mass. In the metering zone, additional heat is applied by conduction from the barrel surface. As the chamber in front of the screw becomes filled, it forces the screw back, tripping a limit switch that activates a hydraulic cylinder that forces the screw forward and injects the fluid plastic into the closed mold. An antiflowback valve prevents plastic under pressure from escaping back into the screw flights.
The clamping force that a machin

几个方法被用于强迫或注射熔化塑料入模子。 如图1-1所显示,在更大的机器的最常用的系统是轴向交换的螺丝。 螺丝作为组合射入和成为可塑单位。当塑料哺养到转动的螺丝,它穿过三个区域如显示: 饲料,压缩和测量。 在,螺丝飞行深度逐渐减少之后饲料区域,强迫塑料压缩。工作被转换成热被剪塑料,做它半液体大量。 在测量的区域,传导申请另外的热从桶表面。当在螺丝前面的房间变得填装,它强迫螺丝,绊倒激活液压缸今后强迫螺丝并且注射流动性塑料入闭合的模子的限位开关。 antiflowback阀门防止塑料受到来自逃脱回到螺丝飞行的压力.
夹紧力量的The机器能够施加是大小指定图的一部分1-1 a)射入造型机器b)交换螺丝注射系统和用吨被测量。 概测法可以被用于确定对于一个特殊工作是必需的吨位。 它根据二吨钳位力量每平方英寸投影面积。 如果流程模式是困难的,并且零件是稀薄的,这也许必须去三或四吨

几种方法是使用武力或以注资融化成塑料模具。最常用的制度,在较大的机器,是在网上往复螺杆,如图1-1 。螺杆作为一个组合注射及塑化股。由于塑料是美联储向旋转螺丝钉,它通过三个地带所示:饲料,压缩,和计量。之后,饲料区,螺旋飞行深度是逐渐减少,迫使塑料压缩。工作转换成热量,由剪切塑胶,使这里成为半流体肿块。在测光区,额外热量是适用的传导,从每桶表面。作为商会在前面的螺丝钉成为填补,它的力量螺丝回来,跳闸极限开关,激活了一种液压缸势力螺钉和发扬注入液体塑胶进入闭模。一个antiflowback阀,防止塑料压力下,逃逸到螺丝钉的航班。
该夹紧力说,一台机器是有能力施加是部分的大小指定图1-1一)射出成型机二)往复螺杆注射系统,是衡量吨。一个基于规则的-拇指可以用来确定所需吨位为某个工作。它是基于两吨钳力每平方英寸的投影面积。如果流通格局,是难以和部分偏薄,这可能要到三,四吨。
