具有分区段式加热器的热流道喷嘴
摘要：
一种耦联于热流道喷嘴的喷嘴加热器组件包括由彼此相隔一间隙的至少两个支承区段构成的加热器支承件。紧固于各支承区段的加热器元件被构造成限制两个区段之间的间隙。在其它应用中，将被耦联于热流道的喷嘴加热器组件还可包括加热器支承件，其由单件形成并且构造为包括至少两个轴向间隙的中空螺旋管。加热器元件被紧固于螺旋管，其中螺旋管可被压缩或拉伸，以改变螺旋管和加热器耦联于热流道喷嘴时所产生的夹持力。本实用新型的热流道喷嘴的热分布被改进，并且喷嘴加热器容易制造和拆装。
摘要（英）：

The utility model discloses a hot runner nozzle. A nozzle heating assembly coupled to the hot runner nozzle comprises a heater supporting part consisting of two or more supporting sections, wherein the every two supporting sections are spaced by a gap; a heater element fastened to the every two supporting sections is constructed as the gap for limiting the two sections; in other application, the nozzle heating assembly coupled to the hot runner nozzle also can comprise the heater supporting part which is formed by a single part and constructed as a hollow spiral pipe with two or more axial gaps; the heater element is fastened to the spiral pipe, the spiral pipe can be compressed or stretched to change a clamping force generated when the spiral pipe and a heater are coupled to the hot runner nozzle. According to the hot runner nozzle, the heat distribution is improved; moreover, the nozzle heater is easy to manufacture and dismount.
