ABSTRACT:
The object is to provide an extruding die which is easy to be cleaned and which suffers no unreasonable force during the extrusion.
The extruding die for extruding a honeycomb structure comprises at least two components, a first component and a second component, which are detachable. The first component includes a plurality of supporting bars disposed parallel to each other at regular intervals each of which has hexagonal posts erected thereon at regular intervals. The second component includes a plurality of supporting bars disposed parallel to each other at regular intervals, each of which is fitted in the channels formed on the lower surfaces of the hexagonal posts of the first component, and each of which has hexagonal posts erected thereon at regular intervals and disposed parallel to each other between the hexagonal posts of the first component. The first and the second component, in the condition assembled into a unit, form cell holes like a honeycomb continuously extending from the rear surface to the front surface in the same diameter.
