摘要： PROBLEM TO BE SOLVED: To provide a solidification analysis method for an alloy molten metal in consideration of an supercooled state.
SOLUTION: The solidification analysis method for the alloy molten metal includes a solidification analysis process comprising: a solidification property defining step where supercooling solidification properties showing the correlation between the solid phase ratio or eutectic solidification temperature and the cooling velocity of an alloy molten metal are defined; and a solidification analysis step where, based on the supercooling solidification properties, a solidification process through which the alloy molten metal is solidified in a packed element as a cavity element packed with the alloy molten metal is calculated with the lapse of time. By performing simulation in consideration of such supercooled state, solidification analysis with higher precision can be relatively easily performed on various alloy molten metals.

摘要： PROBLEM TO BE SOLVED: To enable smooth discharge of a gas from a cavity by controlling the melt flow in the cavity, and to obtain good quality castings with less entrainment of gas regardless of shape or size. SOLUTION: The die-casting method comprises pressure-filling a cavity 2 with a molten metal while eliminating the back pressure of the cavity 2 in a die 1 from an exhaust passage 22 and a gas venting runner 21 by opening a pressure reducer 26. Further, the valve devices 27A and 27B are installed in a main runner 21A open to a first area A including a portion apt to accumulate a gas in the cavity 2 and in another main runner 21B open to a second area B adjacent to the first area A, respectively. In the initial stage of injection into the cavity 2, the opening of one valve device 27A is made larger than that of the other device 27B so that the melt flows into the first area A preferentially. After the melt is filled in the area A, the openings of the valve devices 27A and 27B are switched reversely to change the melt flow to the area B, thus running out the gas to the main runner 21B side.

摘要： PROBLEM TO BE SOLVED: To make a filter attain its maximum cleaning capacity and prevent the filter from being damaged. SOLUTION: The filter 22 composed of metal meshes is loaded beforehand in the low-speed advance range 1 of a plunger tip 14 inside an injection sleeve 11. Molten metal M poured from a ladle 13 into the injection sleeve 12 through a molten metal supply port 11 flows toward a mold 16 through the filter 22. During the flow the filter 22 catches foreign substances mixed in the molten metal M such as oxides. As the filter 22 moves according to the advance of the plunger tip 14, the pressure of the molten metal M does not have a great influence on the filter 22 so that the filter 22 is prevented from being damaged. Further, the filter 22 is finally stowed into a biscuit forming section 21 of the mold 16 and can be separated together with biscuit castings from the mold 16 whereby the filter 22 does not obstruct the next casting cycle.
