用于金属材料的挤压模
摘要：
在一些优选实施方式中，用于金属材料的挤压模(10)包括：具有带有逆着挤压方向而面向后方的金属材料压力接收表面(22)的压力接收部(21)的模壳体(20)、设置在模壳体(20)中的阳模(30)和设置在模壳体(20)中的阴模(40)。压力接收部(21)形成为向后突出的凸出构型，并且在压力接收部(21)的外周内设有用于引入金属材料的孔道(24)。孔道入口部(24e)的平面状态开口面积(Sb)与压力接收部(21)的平面状态面积(Sa)的比率设定为0.15至0.80。所述挤压模构造成使得压在金属材料压力接收表面(22)上的金属材料经孔道(24)被引入到模壳体(20)中并且通过挤压孔(11)。
摘要（英）：

In some preferred embodiments, an extrusion die 10 for a metallic material includes a die case 20 having a pressure receiving portion 21 with a metallic material pressure receiving surface 22 faced reIn some preferred embodiments, an extrusion die 10 for a metallic material includes a die case 20 having a pressure receiving portion 21 with a metallic material pressure receiving surface 22 faced rearward against an extrusion direction, a male die 30 disposed in the die case 20, and a female die 40 disposed in the die case 20. The pressure receiving portion 21 is formed into a convex configuratiarward against an extrusion direction, a male die 30 disposed in the die case 20, and a female die 40 disposed in the die case 20. The pressure receiving portion 21 is formed into a convex configuration protruded rearward, and a porthole 24 for introducing the metallic material is provided in an outer periphery of the pressure receiving portion 21. A ratio of a flat state opening area Sb of a porton protruded rearward, and a porthole 24 for introducing the metallic material is provided in an outer periphery of the pressure receiving portion 21. A ratio of a flat state opening area Sb of a porthole inlet portion 24e to a flat state area Sa of the pressure receiving portion 21 is set to 0.15 to 0.80. The extrusion die is configured such that the metallic material pressurized against the metahole inlet portion 24e to a flat state area Sa of the pressure receiving portion 21 is set to 0.15 to 0.80. The extrusion die is configured such that the metallic material pressurized against the metallic material pressure receiving surface 22 is introduced into the die case 20 via the porthole 24 and passes through the extrusion hole 11.llic material pressure receiving surface 22 is introduced into the die case 20 via the porthole 24 and passes through the extrusion hole 11.
