摘要： PROBLEM TO BE SOLVED: To provide a casting aluminum alloy for manufacturing a casting of an aluminum alloy, which causes little irreversible dimensional change and has superior dimensional stability.
SOLUTION: The casting aluminum alloy includes Si, the balance being mainly Al, and further 0.0001 to 0.5 mass% in total of Si-solid-solution-inhibiting elements with respect to 100% of the total mass, which reduce an amount of Si dissolved in an Al-based matrix, by promoting crystallization of Si from a molten alloy, in a solidification step of cooling and solidifying the molten casting aluminum alloy, to impart the casting of the aluminum alloy the superior dimensional stability even in an as-cast condition. The addition of the Si-solid-solution-inhibiting elements reduces the amount of Si dissolved in the Al-based matrix, reduces the amount of precipitated Si which causes the irreversible dimensional change, and thereby enhances the dimensional stability of the casting of the aluminum alloy.

摘要： PROBLEM TO BE SOLVED: To provide a plunger of a die-casting machine, which reduces an amount of porosity even under a low casting pressure.
SOLUTION: The plunger consists of: an outer tip (11) fitted and inserted, movably forward and backward, in a sleeve having a cylindrical space communicating with a cavity of a metallic die; an inner tip (12), which is movable forward and backward with respect to the outer tip roughly at a central part of the sleeve; and an elastic body (21) elastically holding the outer tip. When using the plunger, the elastic body is constricted to project the inner tip to the outer tip just before the cavity is completely fully charged with molten metal, so that the molten metal in the sleeve is further pressurized.

摘要： PROBLEM TO BE SOLVED: To further reliably prevent the mixing of solidified piece at the initial stage into a cast product. SOLUTION: In a fixed die 11 provided with a sleeve 13, a runner 16 and a biscuit-forming part 17 are formed. In a movable die 12, a projecting part 20 protruded so as to be faced to a spouting hole 13b in the sleeve 13 and accommodated in the biscuit-forming part 17 when the die is clamped is arranged. In the projecting part 20, a contracted part 21 is formed in clamping between the inner circumferential surface of the spouting hole 13b in the sleeve 13. The contracted part 21 limits the movement of a metal-net filter 22 so that this filter 22 is not pushed from the sleeve 13 into a cavity 15 by molten metal poured from a sleeve 13 into the cavity 15 in casting. Thus the filter effect is kept until completing the fill-up of the molten metal. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an adhesion evaluation method for a die-cast mold release agent enabling appropriate evaluation of an adhering state of the mold release agent applied to a molding surface of a mold.SOLUTION: An adhesion evaluation method for a die-cast mold release agent includes: an irradiation step of irradiating a coated surface that is formed by spray coating of a coating fluid obtained by dissolving or dispersing the mold release agent and a fluorescent agent in water on a heated molding surface of a mold, with excitation light that corresponds to the fluorescent agent; and a measurement step of receiving fluorescence emitted from the fluorescent agent to measure fluorescence intensity. The measurement step is an intensity distribution measurement step of continuously measuring fluorescence intensity in a specific region of the coated surface to obtain intensity distribution. The adhesion evaluation method further includes an identification step of identifying an index value indexing an adhesion state of the mold release agent in the specific region on the basis of the intensity distribution. Using the index value enables appropriate evaluation of the adhesion state of the mold release agent and thus releasability during die casting even if coating unevenness of the mold release agent is large.
