Description
図7の前記焼結部品Aは、上面に半円状の凹み部1を有し、側面に突起7を有する。図3は前記上ダイ3及び前記下ダイ4の拡大図である。前記上ダイ3には上部成形孔8が形成され、前記第1下ダイ4aには下部成形孔9が形成されている。前記上部成形孔8と前記下部成形孔9は前記第1下ダイ4aの上面において段差無くつながれているか、前記上部成形孔8の方が前記下部成形孔9よりも大きい断面を持つように設定される。前記下部成形孔9の側面には前記焼結部品Aの前記突起7を形成するための段差10を有する。 The sintered part A in FIG. 7 has a semicircular recess 1 on the top surface and a protrusion 7 on the side surface. FIG. 3 is an enlarged view of the upper die 3 and the lower die 4. An upper molding hole 8 is formed in the upper die 3, and a lower molding hole 9 is formed in the first lower die 4a. The upper molding hole 8 and the lower molding hole 9 are set so as not to be stepped on the upper surface of the first lower die 4a, or the upper molding hole 8 is set to have a larger cross section than the lower molding hole 9. The On the side surface of the lower molding hole 9 , there is a step 10 for forming the projection 7 of the sintered part A.
図2は金型側方からの金型断面図である。前記上ダイ3、前記ダイプレート6の上面には、冶金用粉末を供給するフィーダーボックス15が前後摺動可能な状態で接している。前記フィーダーボックス15の前面には、粉末カキ16が設けられている。図1に示すように、前記粉末カキ16には前記溝部11の形状に沿った形状の突起部17が形成されている。前記フィーダーボックス15の前後動作に伴い、前記上部成形孔8及び前記下部成形孔9に供給された冶金用粉末のうち、不要部分の冶金用粉末を前記粉末カキ16の前記突起部17が除去する。 FIG. 2 is a sectional view of the mold from the side of the mold. A feeder box 15 for supplying metallurgical powder is in contact with the upper surfaces of the upper die 3 and the die plate 6 in a state where it can slide back and forth. A powder oyster 16 is provided on the front surface of the feeder box 15. As shown in FIG. 1, wherein the powder oyster 1 6 protrusions 17 conforming to the configuration of the groove 11 is formed. As the feeder box 15 moves back and forth, the protrusion 17 of the powder oyster 16 removes unnecessary metallurgy powder from the metallurgy powder supplied to the upper molding hole 8 and the lower molding hole 9. .
