Molding (Molding Die), and in particular, a mold for using a high-precision molded glass lens. A more complete implementation of the high-precision glass molding was first disclosed in US Patent No. 3,833,347 to Eastman Kodak Company in 1974. In the course of about 20 years of development, the use of mold kernels can be divided into several generations according to the development of various materials and the maturation of the process. The earliest amorphous carbon, silicon carbide (SiC), and Silicon nitride (Silicon Nitride; Si3N4) hard ceramics, metals, precious metal materials, various film applications, even diamond-like films (DLC), boride ceramics, etc. The applicability of the mold core must take into account the following points: (1) release properties to avoid reaction and adhesion with glass; (2) sufficient hardness and mechanical strength to form the glass and avoid surface scratches; (3) High temperature stability to avoid decomposition and reaction in the molding atmosphere; (4) thermal shock resistance to endure thermal cycling during the molding process; (5) processability to process to form specific optical surfaces and consider processing time And cost; (6) mold core life, extending the mold core life can reduce costs. Please refer to Fig. 1 and Fig. 2. What cannot be drawn is a schematic cross-sectional view of a mold core of a conventional mold glass. Please refer to Figure 1. The mold core of the molded glass includes at least the combination structure of the substrate 10 and the protective film 12, or the combination structure of the substrate 10, the buffer layer 14 and the protective film 12, as shown in Figure 2. As shown. The materials of the substrate 10 include non-mirror steel, carbide sand, and tungsten carbide (Tungsten Carbide, WC). The purpose of increasing the structure of the interposer 14 is to increase adhesion, or to facilitate processing, or to facilitate forming.

Description of the invention (λ) If the material of the protective film 12 is amorphous carbon, such as US patent Nos. 3,833,347, 3,844,755, and 3,900,328 have good release properties, but they are difficult to use due to their poor structure, easy damage, easy oxidation, easy cracking, low impact strength, and poor thermal conductivity. Therefore, Eastman Kodak Company subsequently developed hard ceramics such as silicon carbide and silicon nitride, such as U.S. Patent Nos. 4,139,677 and 4,168,961. However, hard ceramics also have the disadvantages of difficult processing, thus reducing their applicability. In addition, sintering Additives such as aluminum oxide (A10J, A10J, boron oxide (B203), etc.) easily react with glass and reduce the mold release property. In order to improve the processing time of mold cores, there are various series of coatings Developed. One of the precious metals series To develop the most complete company of Matsushita, rather than precious metals series of ceramic material, Olympus places the company's development more perfect.

未產生剝離(Peel-Off)現象,表示其附著性良好,此外鍍膜 亦未氧化變色。而第3號至第9號樣品,皆由於剝離而造 成鍍膜損傷。其中第4號至第6號及第7號樣品之類鑽石 薄膜、碳化鈦及氮化鈦等鍍膜,因爲高溫氧化而造成鍍膜 變色與剝離。第3號樣品之碳化矽鍍膜則是由於與玻璃產 生反應而導致破壞。第8號至第9號樣品之鉑、氧化鋁等 鍍膜雖然未氧化,但也因單層薄膜之附著性不佳而導致鍍 膜剝離。 在習知技藝的發展中,就貴金屬鍍膜而言,是以鈾銥 合金(Pt-Ir)系列之貴金屬模仁爲主,應用於SF玻璃,但是 也只能限制在溫度520t~550°C使用,以確保能有上千次 的模造壽命。在後續所發展出之銥鍊合金、銥釕合金系列 貴金屬模仁,則可以適用於較高溫玻璃,但是也只能限制 在使用溫度580°C以內使用。再繼續提高使用溫度時,將 會因爲嚴重的熱腐餓(Thermal Etching)作用,導致模仁表面

Description of the invention (€) The test results are shown in Table 1. No. 1 Samples No.2, i.e., iridium-rhenium alloy, iridium-ruthenium alloy, and other hard film mold cores, have passed 20 mold test and high temperature reaction tests at a temperature of 520t. After the mold, the coating did not peel off (Peel -Off) phenomenon, which indicates that the adhesion is good, and the coating is not oxidized and discolored. The samples Nos. 3 to 9 are damaged due to peeling. Among the samples Nos. 4 to 6 and 7 Diamond-like film, titanium carbide and Plated titanium, etc., because of high temperature oxidation and discoloration caused by film peeling. Sample No. 3 of the SiC film is produced due to the reaction with the glass and cause damage. Although the coatings of platinum and alumina of samples Nos. 8 to 9 were not oxidized, the coatings were peeled due to poor adhesion of the single-layer film. In the development of conventional techniques, as far as precious metal coatings are concerned, noble metal molds of the uranium-iridium alloy (Pt-Ir) series are mainly used in SF glass, but they can only be used at temperatures of 520t ~ 550 ° C. To ensure that it can have a molding life of thousands of times. The precious metal molds of the iridium chain alloy and iridium ruthenium alloy series developed in the following can be applied to higher temperature glass, but they can only be used within 580 ° C. If you continue to increase the use temperature, the surface of the mold kernel will deteriorate rapidly and cannot be used due to the severe thermal etch effect. Therefore, the main purpose of the present invention is to provide a mold core for molding glass, and add chromium nitride (CrN), Tantalum Nitride (TaN), and others to the precious metal protective film of the iridium-rhenium alloy and iridium-ruthenium alloy series. Ceramic components such as nitride or alumina.

The design of the invention (intermediate layer) is added to increase the adhesion between the protective film and the substrate. Additives can relax the restrictions on the application of precious metal protective films such as iridium-osmium alloys and iridium-ruthenium alloy series, increase the variable range of composition ratios, and increase the service life and temperature of mold cores, in order to improve conventional molded glass The shortcomings of the model. According to the purpose of the present invention, a mold core for molding glass is provided, which includes the following structures: a substrate, and a protective film on the substrate. This protective film has a molding surface from which the molding groove is defined as a molding glass. The material of the substrate includes tungsten carbide, and the material of the protective film includes noble metal alloys such as iridium-rhenium alloy or iridium-ruthenium alloy containing chromium nitride, nitride nitride, other nitrides, or aluminum oxide. Adding ceramic components to the protective film can improve the composition limit of the precious metal protective film in application and increase the temperature of the mold kernel. An intermediate layer may also be added between the substrate and the protective film, such as nickel-containing iridium chain alloy (Ir-Re-Ni) or nickel-containing iridium-ruthenium alloy (Ir-Ru-Ni), etc. to increase the substrate Adhesion to the protective film extends the life of the mold. In the present invention, the protective film coated on the surface of the mold kernel is a precious metal alloy such as iridium-rhenium alloy or iridium nail alloy series containing ceramic materials such as chromium nitride, nitrided nitride, other nitrides, or alumina. In the application of molding, the service life of the mold core can reach 5000 times at a high temperature of 580 ° C, and the quality of the molded product can still maintain the optical quality of the roughness below 丨 〇A. Due to the large molding temperature range, optical glass can be made more selective 'for a wider range of optical designs, and it is more feasible to promote mass production technology.

Moulds used at higher temperatures and longer life than conventional techniques. In addition, due to the unique coating process of the present invention, the limitation of the content of chromium nitride, tantalum nitride, other nitrides, and other additives such as alumina can be reduced, thereby making it easier to control the process, and the stability of the finished product is high. Cost is lower.
