Description of the Related Art Conventionally, as a method for producing various metal products, there have been known methods of using molten or semi-molten metal such as pressure casting, molten metal forging, die casting, rheocasting and pressure infiltration. Various processing methods are known.

Molten metal leaks from the gap with the platen,
There is a problem that it is very difficult to maintain a high pressure inside the mold. In such a method of pressurizing molten metal or semi-molten / semi-solidified metal, the inner surface of the mold opening and the outer surface of the pressure rod perform relative sliding motion, but cannot withstand high-temperature and high-pressure molten metal. In fact, there is hardly any suitable sealing material that can seal the sliding surface.

Alternatively, there is an essential feature in that the pressure plate has a thickness larger than the gap formed by the difference between the outer diameter of the pressing plate and the inner diameter of the mold opening.

You may make it insert a pipe material (2). In any case, in the present invention, the inner diameter (D 2 ) of the opening of the mold (1), the outer diameter (D 1 ) of the pressing rod or the pressing plate (3), and the thickness (t) of the pipe material (2) are described. ) Determines the thickness reduction amount due to the deformation of the pipe material (2). That is, when the deformation of the pipe material (2), that is, the amount of reduction in the wall thickness is large, the sealing property of the molten or semi-molten / semi-solidified metal (4) inside the mold (1) surely increases. )
If the load required for the deformation of the pipe material (2) becomes large, and conversely, if the deformation of the pipe material (2), that is, the amount of reduction in the wall thickness is small, the sealing property of the molten or semi-molten / semi-solidified metal (4) inside the mold (1) becomes poor Although uncertain, the load required to deform the pipe material is reduced. The dimensions of the mold (1), the pipe material (2), and the pressure rod or the pressure plate (3) actually used are determined in consideration of such a relationship. At that time, in consideration of the mechanical load on the pressure rod or the pressure plate (3) or the mold (1), the pipe material (2) is formed by the mold (1), the pressure rod or the pressure plate (3). Although a relatively soft material is desirable as compared with, it is necessary that the material to be processed has a heat resistance so as not to be damaged during pressurization by the molten or semi-molten / semi-solid metal (4). .
