    • A die for extruding honeycomb structural bodies includes a plurality of ceramic batch exhaust grooves and a plurality of ceramic batch supply apertures. Tubes are fitted in at least some of the ceramic batch supply apertures to improve or make constant the surface roughness and dimensions of inner surfaces of ceramic batch supply apertures through which the ceramic batch passes, thereby producing perfect ceramic honeycomb stuctural bodies. The adjustment of flow of ceramic batch is so simplified that any other controlling plate which would be required in the prior art is not needed for controlling the flow. When the supply apertures have been worn off, the tubes are exchanged by new ones to restore the required inner surfaces easily.
    • 用于挤压蜂窝结构体的模具包括多个陶瓷批料排出槽和多个陶瓷批料供给孔。 在至少一些陶瓷批料供给孔中安装管,以改善或使陶瓷批料供给孔的内表面的表面粗糙度和尺寸恒定,通过陶瓷批料供给孔通过,从而产生完美的陶瓷蜂窝状结构体。 陶瓷批料的流动调整如此简化,使得现有技术中所需的其它控制板不需要用于控制流动。 当供应孔已经磨损时,管被更换,以便容易地恢复所需的内表面。

    • Disclosed herein is a die for extruding honeycomb structural body, which comprises a die base body made of an alloy steel and a plate of a wear resistant alloy which is joined to the front face side of the die base body. In the wear resistant alloy plate are formed forming slits having a sectional profile conforming to that of a honeycomb structural body to be shaped and having a given depth from the front face of the die toward the rear face thereof, and a plurality of openings are formed independently of each other in the die base body from the rear face of the die toward the front face thereof to communicate with the forming slits. The wear resistant alloy plate may be joined to the die base body through an alloy steel plate having the same as or thinner than the thickness of the wear resistant alloy plate. A method of manufacturing such a honeycomb structural body-extruding die is also disclosed.
    • 本发明公开了一种挤压蜂窝结构体的模具,其包括由合金钢制成的模具基体和与模具基体的正面接合的耐磨合金板。 在耐磨合金板中形成形成狭缝的狭缝,其截面形状与待成型的蜂窝结构体的截面形状相同,并且具有从模具的前面朝向其背面的给定深度,并且形成多个开口 在模具基体中从模具的后表面朝向其前表面彼此独立地与形成狭缝连通。 耐磨合金板可以通过与耐磨合金板的厚度相同或更薄的合金钢板与模具基体接合。 还公开了一种制造这种蜂窝结构体挤压模的方法。
