A zinc-based alloy for casting molds which has excellent castability and can obtain sound castings with almost no casting defects, and is therefore suitable for casting molds used in plastic injection molding or press working, and the same. Regarding molds made by casting. [Prior Art] Conventionally, AQ4.1% by weight, Cu3. O weight%. Mg0
.. A zinc alloy ZAS (trade name) containing 0.5% by weight is widely used. This alloy can be cast at a temperature of 410 to 450°C, has good pattern reproducibility and casting surface, and does not require any special molten metal treatment, making it extremely easy to cast. In addition, 22 to 27 kgf/a can be produced by sand casting.
A tensile strength of m is obtained. However, in recent years, with the trend toward high-mix, low-volume production, studies are being conducted to upgrade zinc molds for low-volume production, that is, to improve their strength. For this reason, as a zinc-based alloy related to this, for example, Japanese Patent Publication No. 51-5342 discloses AQ2 to 12% by weight, Cu1
~10% by weight, Mg0.01~0.5%, Be0.
02 to 0.15% by weight, TiO. 01-1.5% by weight
A wear-resistant zinc-based alloy containing 0.01 to 3.0 weight percent of Ag and the balance being zinc is disclosed. moreover,
JP-A-63-38548 discloses Afil ~10% by weight, Cul ~15% by weight, and Mg0.01-0.5% by weight.
,Y.O. A zinc-based alloy containing 0.2 to 1.0 weight percent and the balance Zn, or JP-A-63-65043 contains 5 to 15 weight percent of Cu, 0.2 weight percent or less of Mg, and 0.05 to 3 lanthanide. A zinc-based alloy is disclosed that contains Zn in weight percent and AQ in an amount that satisfies a specific formula, with the balance being Zn. [Problems to be solved by the invention] However, in the invention described in Japanese Patent Publication No. 51-5342, trace addition elements such as Be, Ti, and Ag are easily oxidized in the molten metal, and dross entrainment occurs, making casting difficult. There was a risk that defects would occur and the manufacturing yield of plastic molded products would decrease. Furthermore, since the invention described in JP-A No. 63-38548 and the invention described in JP-A No. 63-65043 each contain Y and lanthanide, these elements are oxidized, resulting in casting problems such as dross entrainment. Defects were likely to occur, and there were problems similar to those mentioned above.

c一以内であることが必要である。In view of the above circumstances, the present invention aims to provide a zinc-based alloy for molds that has high mechanical strength, excellent castability, and almost no casting defects, and a mold made by casting the same. Purpose. [Means for Solving the Problems] In order to achieve the above-mentioned problems, the present inventors, in the course of intensive research, carried out the machining process described in Japanese Patent Application No. 1-5983 filed by the present applicant. Mold, i.e. 6-12% by weight
Focusing on the zinc-based alloy, which consists of Afl-5.5 to 12% by weight Cu-Mg-Zn and requires machining due to its poor castability, various studies were conducted by changing the range of this alloy. Surprisingly, it has been found that within a certain limited range of strength of 82 and Cu, castability is extremely good and almost no casting defects are observed. The present invention was made based on such findings, and includes AQ of 6.5 to 7.5% by weight, Cu of 5.6 to 6.5% by weight, MgO. 01 to 0.20%, the remainder consists of Zn apart from unavoidable impurities, the Ragonne flow length at 430°C is 230mm or more, the solidification temperature range is 13°C or more,
And there is one defect of 50μ or more within 3mm of the surface of the casting.
Zinc-based alloy for molds made by casting and molds made by casting the same. One end of a glass tube with an outer diameter of 6+amφ and an inner diameter of 4mφ is inserted into this molten metal, and a negative pressure of 240 mmHg is applied from the other end.At this time, a long length of metal flows into the glass tube and solidifies. In the present invention, in order to ensure good castability, the Ragonne flow length at 430°C is required to be at least 230 mm.If the Ragonne flow length is less than 230 mm, the flowability of the metal will deteriorate. This makes it difficult for hot water to reach every corner of molds of various shapes.In addition, in order to obtain good castability, it is necessary that the solidification temperature range width is 13℃ or more.The solidification temperature range width is 13℃ or more. If it is narrower than ℃, casting defects are likely to occur inside the casting.The reason for this is not clear, but it is thought to be because the difference in cooling temperature between the surface of the casting and the inside becomes smaller, making it difficult for air bubbles to escape. Furthermore, in the present invention, in order to obtain a sound cast product, one defect of 50 μl or more is present within 3 mm of the surface of the cast product per 100.
c must be within one.
ここで、改めて本発明の或分組成範囲の限定理由を説明

5.6重量%に達しないと凝固温度幅が狭くなり、鋳造
欠陥が多くなる。AQ: When it exceeds 7.5%, the solidification temperature range becomes narrower.
There will be more casting defects. On the other hand, if the content does not reach 6.5% by weight, fluidity decreases, resulting in poor flow of the molten metal and more casting defects. Cu: When the content exceeds 5.6%, the fluidity decreases, the flow of the metal becomes poor, and casting defects increase. Furthermore, it becomes difficult to perform texturing, which is used for some plastic shapes. Texturing here refers to the process of etching a fine uneven pattern on the surface of a mold in order to add a pattern to the surface of a plastic product. Conversely, if the Cu content does not reach 5.6% by weight, the solidification temperature range becomes narrow and casting defects increase.

型上部をバーナーで加熱′するトップヒートを行った。The method for casting such an alloy of the present invention may be the same as that for ZAS alloy, and in order to avoid segregation of aluminum during solidification, it is preferable to use a top heat method in which the top part is heated and the bottom part is cooled. [Function] As described above, since the present invention is made of AQ-Cu-Mg-Zn and no other additive elements are added, there is no possibility of casting defects caused by the generation of dross and its entrainment. Furthermore, since the Ragonne flow length is greater than a predetermined length and the solidification temperature range width is greater than a predetermined value, it has excellent castability and mechanical strength of 36 kg/+im'' or more.
Examples of the present invention will be described below. Example A zinc-based alloy having the composition shown in Table 1 was prepared by melting it in a graphite crucible. Next, these alloys were melted again and cast into test molds at a casting temperature of 430°C, and during solidification, top heating was performed by heating the upper part of the mold with a burner.
