    • PURPOSE:To prevent the thermal decomposition of powder as well as the ignition and explosion of floating powder by staying the powder on the upside of a cooled temperature-regulating heat medium circulation section without direct contact with the upside of a heated mandrel. CONSTITUTION:A heat insulation section 12a is provided in the upper part of a mandrel 15, a heat insulation section 12a is provided on the inner surface of the mandrel 15, and the heat insulation sections 12a and 12b are integrally made up. A temperature-regulating heat medium circulation section 14a is provided on the upper surface of the mandrel 15, and a heat medium circulation section 14b is provided between the through portion of the mandrel 15 and the periphery of a powder feed tube 2, and they are integrally connected with each other. Spaces 9a and 9b are formed between the heat insulation sections 12a and 12b and the heat medium circulation sections 14a and 14b in such a way as to more enhance the heat insulation effect. Since the powder 7 is insulated from the heat of the mandrel 15 and a die 1, the thermal decomposition of the powder can be prevented, and also since the powder 7 is stayed on the upside 18 of the heat medium circulation section 14a, the formation of floating powder can be suppressed.
    • 目的:为了防止粉末的热分解以及浮动粉末的点火和爆炸,将粉末停留在冷却的温度调节热介质循环段的上侧,而不与加热心轴的上侧直接接触。 构成:在心轴15的上部设有绝热部12a,在心轴15的内表面设置绝热部12a,隔热部12a,12b整体地构成。 在心轴15的上表面设置有温度调节用热介质循环部14a,在心轴15的贯通部与粉末供给管2的周边之间设置有热介质循环部14b, 彼此一体地连接。 在隔热部12a,12b与热介质循环部14a,14b之间形成有空隙9a,9b,从而能够进一步提高隔热效果。 由于粉末7与心轴15和模具1的热绝缘,因此可以防止粉末的热分解,并且由于粉末7停留在热介质循环部分14a的上侧18上,所以形成 的浮粉可以抑制。
