<p><P>PROBLEM TO BE SOLVED: To provide an extrusion die device which can extrude a product with a uniform thickness, and a method for producing an extruded component. <P>SOLUTION: The extrusion die device is obtained in such a manner that a die hole is formed by the protrusion section of a male die and the hole section of a female die. The protrusion section of the male die includes a plurality of support sections separately arranged in a line, and a head section and a neck section formed at each support section. The gap among the support section, head section and the hole section of the female die constitutes the die hole. The gap formed between the adjoining support sections is made into a stock introduction path with a side ellipse shape. The gap between the head sections connected to the support parts adjoining in a line is made into a stock passage with an equal width. Further, the boundary section between the stock introduction path and the stock passage is made into a corner-rounded stock communication path. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
