摘要： PROBLEM TO BE SOLVED: To provide an injection molding nozzle which can improve moldability despite the fact that a hard workable material with increased viscosity as a molding material such as a rubber or a heat-curable resin.
SOLUTION: In this injection molding nozzle, the molding material supplied from a screw 13 of a cylinder part 11 is temporarily stored in a heating chamber 12b of a nozzle part 12, then the molding material which is temporarily stored inside the heating chamber 12b is heated up to a melting temperature complying with the material characteristics of the molding material and this heating-up state is kept as it is until the completion of injection by an induction heating coil 15 positioned outside the nozzle part 12. Further, simultaneously with the completion of injecting the molding material temporarily stored inside the heating chamber 12b, the interior of the heating chamber 12b is cooled by a refrigerant supplied to a cooling channel 12a, and at the same time, the supply of the refrigerant is suspended during heating by the induction heating coil 15 and the current temperature of the nozzle part 12 is monitored by a temperature sensor 16.

摘要： PROBLEM TO BE SOLVED: To obtain the temperature control device for an injection molding machine constituted so as not to solidify a resin in a nozzle part provided before a cylinder part when injection molding operation is stopped.
SOLUTION: When molding operation is stopped and a heater cutting-off demand signal is outputted (a1), the supply of voltage to the heater of the cylinder part is stopped first (a2). Thereafter, the supply of power to the nozzle part is stopped after the elapse of a set predetermined time Tw (a3-a6). The nozzle part is rapidly cooled because the heat capacity thereof is smaller than that of the cylinder part but, since the supply of power to the heater of the nozzle part is stopped so as to be delayed by a predetermined time as compared with the cylinder part, the resin in the nozzle is not solidified before the resin in the cylinder part is solidified. By this constitution, the discharge passage of the gas generated in the solidifying process of the resin in the cylinder is ensured and the damage to the cylinder can be prevented.

摘要翻译：要解决的问题：为了获得注射成型机的温度控制装置，其构成为在注射成型操作停止时在设置在气缸部件之前的喷嘴部分中固化树脂。解决方案：当模制操作停止并且输出加热器切断需求信号（a1）时，首先停止向气缸部件的加热器供电电压（a2）。此后，在经过设定的预定时间Tw（a3-a6）之后停止对喷嘴部分的供电。由于其热容量小于气缸部分的喷嘴部分而被快速冷却，而是因为与气缸部分相比，停止向喷嘴部件的加热器供电以延迟预定时间在气缸部分中的树脂固化之前，喷嘴中的树脂不固化。通过这种结构，确保了在气缸中的树脂的凝固过程中产生的气体的排出通道，并且可以防止对气缸的损坏。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a heat insulating cover capable of being simply attached to or detached from the injection or extrusion device of a molding machine.
SOLUTION: The heat insulating cover 10 for the injection or extrusion device is equipped with a heat insulating layer 12 filled with a flexible heat insulating material and an outer skin layer 13 which covers the outside of the heat insulating layer 12 and comprises a sheet having heat resistance. A Velcro fastener(R) 14 having heat resistance is attached to the outer skin layer 13 in the vicinity of the end part thereof. This heat insulating cover 10 for the injection or extrusion device is wound around the outside of the heater 3 of the injection or extrusion device of the molding machine to be fixed thereto by the Velcro fastener(R) 14.
