    • A system for the injection molding of plastic material is described. The system has an injection device of the hot runner type for the injection of a plastic material, in a molten state, into a mold, a circular diaphragm to distribute evenly and circularly in a cavity of the mold, through a circular injection gate or port, the plastic material injected by the injection device, and control means adapted to control an operation of the molding system an including a heating inductor and heating means provided to heat and keep at a hot temperature the injection device, and a thermocouple being arranged in an area of the circular injection gate. The control means are adapted to control through the heating inductor a molding cycle of a piece. The system is particularly suitable for molding pieces which typically have a form of a solid of rotation with cylindrical outer surfaces, and is configured in an area of the circular injection port so as to avoid a formation of waste or superfluous parts which must be subsequently removed from the piece, once molded.
    • 描述了塑料材料注射成型系统。 该系统具有热流道类型的注射装置,用于将熔融状态的塑料材料注入模具中,圆形隔膜通过圆形注射门或端口均匀且圆形地分布在模具的空腔中 由喷射装置喷射的塑料材料,以及适于控制模制系统的操作的控制装置,包括加热电感器和加热装置,所述加热电感器和加热装置用于加热并保持在高温下的注射装置,热电偶被布置在 圆形注入口的面积。 控制装置适于通过加热电感器来控制一片的成型周期。 该系统特别适用于通常具有圆柱形外表面的具有旋转实体形状的模制件,并且构造在圆形注射口的区域中,以避免形成必须随后移除的废物或多余部件 从一块,一次成型。

    • A heating element for metallic plastic injection nozzles with a tubular hollow metal body (2), which surrounds the nozzle body of an injection molding device in a heat-transmitting manner. The hollow body has an outer and/or inner jacket surface with one or more grooves (3, 4), extending in a thread-like manner at least in some sections, with inserted tubular heating body structure (with a heating body or bodies) (5). The heating body structure has electric terminals (6, 7) projecting away from the hollow body (2). In addition, a thermocouple, with a sensor tip (9) is in thermal contact with the material wall (15) of the plastic injection nozzle (17) in an end area of the tube wall, is arranged in a guide groove (4). To ensure that the temperature of the material tube, which temperature is to be regulated, is homogeneous at always the same measuring point and is shielded from the direct effect of heating, the sensor tip (9) is fixed in a heat-transmitting manner in a groove-like recess (11) of a tube wall section (20), which is thermally separated from the tube wall (2′) by two front-side notches (21, 22) and which, being subject to a radial pressing force in a radially flexible manner, is in gap-free, two-dimensional thermal contact with the nozzle body (15).
    • 一种用于具有管状中空金属体(2)的金属塑料注射喷嘴的加热元件,其以热传递方式围绕注射成型装置的喷嘴体。 中空体具有外部和/或内部护套表面,其具有一个或多个凹槽(3,4),至少在一些部分中以线状方式延伸,其中插入的管状加热体结构(具有加热体或体) (5)。 加热体结构具有远离中空体(2)突出的电端子(6,7)。 此外,具有传感器尖端(9)的热电偶在管壁的端部区域与塑料注射喷嘴(17)的材料壁(15)热接触,布置在引导槽(4)中, 。 为了确保材料管的温度在哪个温度下被调节,在总是相同的测量点处是均匀的,并且不受加热的直接影响,传感器尖端(9)以热传递方式固定 管壁部分(20)的槽状凹部(11),其通过两个前侧切口(21,22)与管壁(2')热分离,并且经受径向挤压力 以径向柔性的方式与喷嘴体(15)无缝隙地二维热接触。
