    • An apparatus for retaining a heater on an injection molding nozzle comprises a retaining body configured to fit around the injection molding nozzle. The retaining body has two flanges extending inward. One is configured to be received in a groove in the injection molding nozzle; the other is configured to be received in a groove in the heater. An axial slot allows the retaining body to elastically spread outward. The retaining body also has at least one aperture that receives a thermocouple. The aperture is preferably an elongated hole having an axis parallel to a longitudinal axis of the retaining body. Preferably the heater is a thick-film heater and the thermocouple is installed adjacent one on the resistive elements of the thick-film heater. When the resistive elements produce different heat levels, the thermocouple is preferably installed adjacent the resistive element that produces the greatest heat.
    • 用于将加热器保持在注射成型喷嘴上的装置包括构造成围绕注射成型喷嘴安装的保持体。 保持体具有向内延伸的两个凸缘。 一个被配置为容纳在注射成型喷嘴中的凹槽中; 另一个被配置为被接收在加热器中的凹槽中。 轴向槽允许保持体向外弹性扩展。 保持体还具有至少一个接收热电偶的孔。 该孔优选为具有平行于保持体的纵向轴线的轴的细长孔。 优选地,加热器是厚膜加热器,并且热电偶被安装在厚膜加热器的电阻元件上。 当电阻元件产生不同的热量时,热电偶优选地安装在产生最大热量的电阻元件附近。

    • The invention relates to a nozzle (10) for an injection moulding tool, comprising a nozzle body (12), which may be mounted on a tool or distributor and in which at least one flow channel (22) for a material melt is arranged, which discharges at the end of, or in a nozzle tip (26). The nozzle body (12) comprises at least one essentially flat side surface (14, 15), which carries or accepts, in a plane contact and/or arrangement, a heating and/or cooling device (28, 28'), for the material melt, in order to be able to arrange the moulding cavities extremely closely in two independent spatial directions. In a particular embodiment, the nozzles (10) are arranged parallel and tightly packed together in a nozzle row (R), whereby two side surfaces (S), of the nozzle row (R), which face each other, are provided with heating or cooling devices (28, 28'), which may be collectively connected, by means of a common external connector (34), to a heating or cooling circuit.
    • 一种用于注射模制工具喷嘴(10)有一个工具或其中在或在喷嘴尖端(26),流路(22)的端部向外开口被设计用于熔融材料,至少歧管安装喷嘴主体(12)。 为了在两个独立的空间方向上,以实现非常接近谐振腔间距,所述喷嘴主体(12)至少一个基本上平坦的侧表面(14,15),其(在平坦的连接和/或布置中,加热和/或冷却设备28,28 “)携带的熔融材料,或者接收。 在一个具体的实施方案中,喷嘴列内的喷嘴(10)(R)平行地布置相互靠近,其中,设置喷嘴列(R)的加热和/或冷却设备(28,28“)两个相对侧表面(S), 通过共同的外部连接器(34)的基团可以连接到一个加热或冷却回路。
