DEVICE AND METHOD FOR CASTING HIGH MELTING POINT METAL

摘要

PURPOSE: A device and a method for casting high melting point metal are provided to maximize a driving force for injection of molten metal by controlling the pressure of a double chamber. CONSTITUTION: A device for casting high melting point metal comprises a first chamber(12), a second chamber(16), an opening and closing part(40), a vacuum part, a pressurizing part, and a rotating part(70). The first chamber is equipped with a crucible(14) for melting metal. The second chamber is connected to the side of the first chamber and equipped with a mold inside. The opening and closing part keeps airtight between the first chamber and the second chamber and selectively opens a molten metal channel. The vacuum part is connected to the first chamber and the second chamber and forms a vacuum inside the first and second chambers. The pressurizing part is connected to the first chamber and pressurizes the first chamber. The rotating part rotates the first chamber so that the second chamber is located under the first chamber and molten metal in the crucible drops into the mold(30) of the second chamber.
