きなかつた。(Prior art) Conventionally, in order to mold foamed metal into a columnar or plate shape, it was molded using a mold having a cavity corresponding to the molded product, or a large block was manufactured and then shaped into a predetermined shape. A cutting method is used. However, these methods have the disadvantage that manufacturing costs are very high. Moreover, when molding columnar or plate-shaped items, it is necessary to stir within each mold in order to uniformly disperse the foaming agent.
For example, when manufacturing small molded products such as columns with a diameter of 50 mm or less or plate-shaped objects with a thickness of 50 mm or less,
Stirring was difficult and uniform metal foam could not be produced.

複雑な形状のものは成形することができなかつ
た。 In addition, in order to foam-mold objects with complex shapes that are difficult to uniformly stir, a so-called casting method is used, in which a foaming agent is added and stirred, and then molten metal is poured into a casting mold. The molten metal after adding the blowing agent had high viscosity and poor flow, making it impossible to form objects with very complicated shapes.

As the volume increases, the pressure increases, thereby applying pressure to the second mold 2. The second mold 2 applies pressure to the foam 6 by its own weight, so that the increased volume of the foam 6 enters the second cavity 5 from the first cavity 3 . Since the upper part of the cylindrical body 4 is open, the foam 6 rises in the second cavity 5 and reaches a predetermined height, and is then cooled to form a molded product of a predetermined size into the second cavity. Formed in cavity 5. The foaming rate can be determined depending on the intended use of the molded product, but the porosity is usually 60% or more.
