原因となる。(Prior art) When molds used in conventional die casting methods, molten metal forging methods, etc. are used to mold high-temperature molten metal, that is, molten metal with a melting point of about 900 to 1,600°C, the fatigue of the mold is significant and generally It becomes unusable after 10,000 steps, resulting in poor economical practicality and a rise in product costs.

っている。In addition, in the case of high-temperature molten metals, the amount of gas generated during solidification is larger than that of metals with low melting points, but conventional molds have holes or grooves that communicate with the atmosphere to form gas vent passages. After the molten metal flows into the pipe and a coagulated film is formed, effective degassing is not performed, which in turn causes the formation of cavities and gas cavities.
