が形成され、形状を損する欠点があった。By the way, as shown in FIG. 1, before the start of molding, air is present between the thin plate 2 to be molded and the concave surface 1a, and as the molding progresses, the air inside passes through the small hole IC and flows into the exhaust port 1.
d, but in the portion of the thin plate 2 facing the pore 1C, as shown in FIG.
This has the disadvantage of causing a loss of shape.
この考案は上記の欠点を改善することを目的とするもの
である。This invention aims to improve the above-mentioned drawbacks.
以下、この考案の一実施例を第４図、第５図により説明
する。An embodiment of this invention will be described below with reference to FIGS. 4 and 5.
図において、第１図〜第３図と同一符号は同一または相
当部分を示し、８は焼結合金等で形成された多孔性金属
体で、多孔性金属体８としては０．０１ｍｍ〜０．１ｍ
ｍの多数の空胴が形成され、通気性のあるものが用いら
れる。In the figure, the same reference numerals as in FIGS. 1 to 3 indicate the same or corresponding parts, and 8 is a porous metal body made of a sintered alloy or the like, and the porous metal body 8 has a diameter of 0.01 mm to 0.0 mm. 1m
A large number of cavities of m are formed and a breathable material is used.
また、多孔性金属体８の側部は成形型１内の空気を排出
する排気口１ｄに連通している。Further, the side portion of the porous metal body 8 communicates with an exhaust port 1d for discharging the air inside the mold 1.
以上のように構成され、成形開始とともに被成形薄板２
には、図示されない加圧装置により液圧が加えられ、被
成形薄板２は成形型１の凹面部１ａに押圧され、第５図
に示される形状に欠陥のない成形品７が得られる。With the above structure, when forming starts, the thin plate 2 to be formed
In this step, hydraulic pressure is applied by a pressure device (not shown), and the thin plate 2 to be formed is pressed against the concave surface 1a of the mold 1, thereby obtaining a molded product 7 having no defects in shape as shown in FIG.
また、成形開始とともに成形型１内の空気は圧縮され、
その結果内部の空気圧が高まるため、圧縮された空気は
多孔性金属体８内の空胴を通り、排出口１ｄから外部に
排出される。Moreover, the air in the mold 1 is compressed as molding starts,
As a result, the internal air pressure increases, and the compressed air passes through the cavity within the porous metal body 8 and is discharged to the outside from the discharge port 1d.
上記実施例においては、液圧を使用したものを示したが
、被成形薄板の加圧手段はこれに限るものではなく、気
圧あるいは押型による場合にも同様に実施することがで
