Description of invention (10 15 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, this print is related to the metal casting method ', especially about a method of pound heating that continuously heats the pound liquid during the casting process. The method of making metal pounds, especially the precision casting of thin shell components, "When the molten metal mash is injected from the mouth, and flows into the tool through the casting path," the metal surface fluid and the wall of Yao wheel and The part where the mold is in contact with the wall is prone to early cooling, especially in the mold, because the space in the mold is very narrow (because it is a thin shell component casting), the metal that is cooled earlier may block the place, causing The most unwilling problem in the casting process is the casting defect. Even if the casting defect does not occur, the crystal structure of the early cooling metal casting solution will change. Therefore, the material structure of the cast components often has residual stress or Lattice defects occur. The conventional solution is to preheat the mold to reduce the problem of early cooling of the molten metal. However, after preheating, The mold will still decrease its temperature with the passage of time, and the temperature after its preheating cannot reach the temperature close to the metal ~ liquid (generally the temperature of the metal halide is at least 8000 or more). Therefore, this The method cannot completely avoid the phenomenon of early cooling of the casting solution during the casting process. The main purpose of the present invention is to provide a casting method for continuously heating the casting solution during the casting process. Continue to heat the casting channel and the casting solution in the mold to keep it at a certain temperature to avoid early cooling of the casting solution. In order to achieve the aforementioned object of the invention, the present invention provides a casting that continuously heats the casting solution during the casting process. The method is to inject the metal casting liquid through the mouth, make it flow through the casting path, and finally reach the mold process, using induction ------------ 2 · loading · (Please read the back (Notes fill out this page)
