摘要： PURPOSE:To prevent trouble from occurring such as adhesion of a thermally crosslinkable high-molecular material into a tubular heater due to thermal crosslinking of the material, by stopping the supply of an electric current to a tubular heater when the material can not be injected normally into a mold after the material has been passed from an injection cylinder into the tubular heater. CONSTITUTION:When a thermally crosslinkable high-molecular material is melted in an injection cylinder 12 and the melted amount thereof reaches a prescribed amount, then immediately after the melted material is passed through a tubular heater 20 to be heated its crosslinking temperature, it is injected into the cavity 26 of a mold 22 to produce a thermally crosslinked molded item. In this case, after a command for starting the injection is issued, if a prescribed period has passed and the pressure in the injection cylinder 12 does not attain its prescribed pressure or if the prescribed period has passed and the temperature of the tubular heater 20 becomes a prescribed temperature or over, the electric power supply to the tubular heater is stopped.
摘要翻译：目的：为了防止由于材料的热交联而引起的热交联性高分子材料粘附到管状加热器中的麻烦，通过在材料不能正常注入时停止向管式加热器供应电流在材料从注射筒通过到管式加热器之后，进入模具。构成：当可热交联的高分子材料在注射筒12中熔化并且其熔融量达到规定量时，则在熔融材料通过管状加热器20之后立即将其交联温度加热，注入进入模具22的空腔26中以产生热交联的模制件。在这种情况下，在发出开始注射命令之后，如果经过了规定的时间并且注射缸12中的压力未达到其规定的压力，或者如果规定的时间过去，并且管状加热器20的温度变为规定的温度以上，停止对管式加热器的电力供给。

摘要： PURPOSE:To obtain a nozzle device for injection molding machine, which is capable of regulating the mixing and dispersing conditions of materials by changing the cross section of a flow path for the materials, by using a system in which the aperture between the conical projection of a cylinder and the conical recession of the cylinder head is regulated by the axially directed movement of the cylinder head. CONSTITUTION:The female screw 21 of a cylinder head 19 is screwed onto the male screw 13 of a cylinder 12, and slackening and loosening between the female screw 21 and the male screw 13 are prevented by a lock nut 22. A flow path 23 for materials is formed between the conical projection 15 of the cylinder 12 and the conical recession 18 of the cylinder head 19. The lock nut 22 is loosened, and the cylinder head 19 is turned and moved in the axial direction, to regulate the aperture delta in the flow path 23 for materials.
