摘要： PROBLEM TO BE SOLVED: To prevent scattering of molten metal and thus improve product quality.SOLUTION: A casting apparatus includes: a mold for forming a cavity with an opening on the lower side; a pressurization chamber that is disposed on the lower side of the mold to store molten metal and forms a closed space above the molten metal; a cylindrical stoke that has an upper end opening communicated with the opening of the cavity and a lower end opening immersed in the molten metal within the pressurization chamber; pressurization means for supplying gas to the closed space of the pressurization chamber to pressurize inside of the pressurization chamber; decompression means for discharging the gas from the cavity to decompress inside of the cavity; and a control device. When molten metal is filled in the cavity from the pressurization chamber, the control device allows the pressurization means to pressurize inside of the pressurization chamber until the molten metal reaches the opening of the cavity, and after the molten metal reaches the opening of the cavity, the control device allows the decompression means to decompress inside of the cavity while pressurization of inside of the pressurization chamber is continued.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a titanium compressor impeller of high precision where extensively fitted excess thickness is extensively removed as removal margins in a production process, thus dimensional accuracy upon working is increased, and, as the simplification or obviation in the correcting operation of a rotary balance is attained, and product yield is improved.
SOLUTION: The outer circumferential face of a front casting boss section 21 in a titanium casting is fixed by a chuck of a lathe. A plurality of receiving plates 4 projecting from the lathe side are located between respective casting blades 27, 28, and further, the tips thereof are pressed against the nose face 31 of a disk-shaped large diameter part formed at the second half part of a casting core section. With the nose face 31 of the large diameter part in the casting core section 23 and the outer circumferential face of the front casting boss section as standard faces, the titanium casting is held by the chuck and the receiving plates, so as to be rotated. The edge faces and outer circumferential face of a rear casting boss section 24, the back face and outer circumferential face of the casting core section, and the trailing edges of a casting full blade and a casting splitter blade are machined, thus the parts equivalent to the excess thickness of these regions are removed from the titanium casting.

摘要： PURPOSE:To produce a thin-walled and defect-free Mg alloy product having an intricate shape by vacuum casting by introducing nonoxidative gas into a holding furnace for a molten Mg alloy, closing hermetically the furnace, evacuating the cavity of a casting mold and filling the molten alloy therein. CONSTITUTION:A mold holding means 17 which holds a sand mold 11 is lowered to immerse the mold aperture 15 into the molten Mg alloy in the furnace 1. When the inside of a product cavity 14 is evacuated by sucking the air in the mains 17 through an evacuating port 18, the molten alloy 2 is filled through the sprue 15 into the cavity 14. The means 17 is moved upward upon ending of solidification to close hermetically the aperture 4 of a furnace cover 3. When the molten Mg alloy 2 in the furnace 1 decreases on repetition of the casting, nonoxidative gas is introduced therein through an introducing port 10 to exert an adequate pressure on the metal 2 thereby rising the surface thereof and maintaining the specified bath surface. The product of the Mg alloy having no deterioration in corrosion and gaseous defects tis thus produced by vacuum casting.
摘要翻译：目的：通过将非氧化气体引入熔融Mg合金的保温炉中，通过真空铸造生产具有复杂形状的薄壁且无缺陷的Mg合金产品，密封气化炉，抽空铸模的腔体和填充其中的熔融合金。构成：保持砂模11的模具保持装置17降低，将模具孔15浸入炉1中的熔融Mg合金中。当通过吸入主电源17中的空气来抽出产品腔14的内部时，通过排气口18，熔融合金2通过浇道15填充到空腔14中。装置17在凝固结束时向上移动，以密封地密封炉盖3的孔4。当熔融的Mg合金2在炉1在铸件重复时减少，非氧化气体通过引入口10引入其中，以对金属2施加足够的压力，从而使其表面升高并保持规定的浴表面。因此，通过真空铸造而产生的腐蚀和气体缺陷没有劣化的Mg合金的产物。
