Abstract

PURPOSE:To obtain a core metal which is capable of varying surface patterns of products manufactured by extrusion forming process, by connecting a passage of extrusion material, which is passing through the inside of the core metal, to a mixing chamber in the core metal, and then, by providing this mixing chamber with an opening as a passage for differnet material. CONSTITUTION:The inside of a core metal 6 is provided with a hollow section to be used as a mixing chamber 9, and an inlet passage 11 which is provided on an inlet ring 8 is connected to the mixing chamber 9. On the other hand, a passage 13 for different material is provided in the neighborhood of an outlet where the inlet passage 11 meets the mixing chamber 9 by an extrusion pipe 15 from the center section 14. And, an extrusion material being fed into each inlet passage 11 is pushed toward a forming metallic mold main part 4 through each outlet passage 12 on an outlet ring 10. EFFECT:It is possible, by feeding different material intermittently through a passage 13, for example, to obtain not only a linear pattern but also an irregular- curve pattern which is intermitted like a marble pattern, etc., or which is partly obscured, and what not.
