It was necessary to apply it manually by hand several times per hour, and this burned down the working environment. Further, graphite powder is inevitably attached to the glass product surface, which is a cause of deteriorating the quality.

As disclosed in Japanese Patent No. 6020, there is also a method in which a sprayed film of tungsten or a vapor-deposited film such as TiN is formed on the surface of a base material such as cast iron. It covers the metal layer,
Not only does the cost of the mold rise due to the addition of production equipment and production processes, and reformation due to surface damage, but the mold releasability is not yet complete, and maintenance-free lubricating mold release agents have not yet been achieved.

No. 34 discloses a high-temperature material having excellent high-temperature oxidation resistance. However, although this alloy exhibits excellent oxidation resistance in a high-temperature oxidizing atmosphere, it forms an oxide film when it is used as a glass mold that is in contact with high-temperature glass exceeding 1000 ° C. and is subjected to thermal shock during molding. Since the alumina film is partially peeled off, maintenance-free release agent cannot be achieved.

One of the features of the mold alloy 1020 is that an alumina film is formed in advance by heat treatment before use, and a mold release agent is not required from the beginning of molding. However, in this heat treatment, a small amount of Cu oxide is generated in the alumina film formed in advance due to the composition of the alloy, so that the releasability from glass is good without applying a conventional lubricant. In addition, the generated oxide of Cu deteriorates the wettability with glass, and wrinkle defects and streak defects are easily generated in the product, so that the conventional lubricating release agent cannot be completely eliminated.

一方、８０％超になると成型時の金型定常温度(４００
℃前後)における高温硬さが低下し金型の寿命を損な
う。Next, the reasons for limiting the composition of the alloy of the present invention will be described. The content of Cu was set to 10 to 80% because
If the heat conductivity is less than 10%, the heat conductivity is lower than that of the current cast iron material. To ensure the same productivity as that of the current cast iron material, the cooling fins must be installed as a measure against overheating of the mold even if the cooling air is supplied to the maximum. Installation, etc., and the cost rises.
On the other hand, if it exceeds 80%, the mold steady temperature during molding (400
(Approx. ° C.) lowers the high-temperature hardness and shortens the life of the mold.

超では脆いβ相の出現により金型全体の耐熱疲労強度が
劣化する。Al is an important element for forming an oxidation-resistant film for improving mold release of glass products. The reason why the content of Al is set to 4 to 11% is that if the content is less than 4%, the effect of forming an alumina film which is an oxidation resistant film is small, and the content of Al is 11%.
If it is excessive, the appearance of a brittle β phase deteriorates the thermal fatigue strength of the entire mold.

６％である。[0018] Cr is indispensable for the formation and stabilization of the alumina film, and when cracks occur in the alumina film,
Oxidation resistance can be maintained temporarily by the chromium oxide generated during this time. The required amount is 20% in the iron-chromium alloy, and 3 to 1 depending on the range of the iron component.

の耐熱疲労強度が低下するので好ましくない。Rare earth elements such as Y, Ce and La are used to form and stabilize the alumina film. In particular, as shown in Table 2 of Examples described later, the alumina film is improved in the peeling resistance, and the glass by the film is used. To suppress the binding reaction and achieve maintenance-free release agent. For this purpose, 0.02% or more is required. However, if it exceeds 2%, the thermal fatigue strength of the entire mold at a high temperature decreases, which is not preferable.
