[Prior Art] [0002] A molded glass mold is provided in a mold to form a desired product. Since it forms a desired product under high temperature and high pressure, the material required for the mold should satisfy the following conditions: [0003] 1. Release property to avoid reaction with glass, adhesion phenomenon; [0004] 2. Sufficient hardness and mechanical strength to shape the glass and avoid surface scratches; [0005] 3. High temperature stability, To avoid decomposition in the molding gas or to react with the gas; [0006] 4. Thermal shock resistance to withstand the heat cycle of the molding process; [0007] 5. Machinability to form a specific optical surface, and Consider processing cost and time; [0008] 6. Die life, extend mold life to reduce costs. [0009] In addition, the mold for manufacturing glass is generally composed of a single material, or a combination of a substrate and a protective film, [0010] or a combination structure including a substrate, a buffer layer and a protective film; The material of the substrate is generally stainless steel, tantalum carbide and Tungsten Carbide (WC); the purpose of adding the interposer 093133755 Form No. A0101 Page 4 of 10 0993408626-0 1337175 099 November 150 is used to increase Adhesiveness or processability; while the material of the protective film is purely crystalline, although it has good release properties, it is poor in structure and easy to damage. It is easily oxidized, easily broken, has low impact strength and poor thermal conductivity. And so on, so it is more difficult to use. [0011] In addition, Japanese Patent Application No. CN147165A, published on Jan. 14, 2004, discloses a metal mold core which is mainly composed of a substrate and a protective film, wherein the substrate is tungsten carbide and is used in the substrate. The group of tungsten alloys is mainly used as a protective film by sputtering. However, because the substrate is a metal such as tungsten carbide, its thermal expansion coefficient is large, and it is easy to make the dimensional parameters of the molded glass to be deviated, which does not reach the required precision, and the material price of the mold is high. Not conducive to reducing costs. [0013] In view of the above-mentioned shortcomings of the mold-molding technology of the conventional molded glass, it is necessary to provide a mold core and a mold manufacturing method which are low in manufacturing cost, high in mold-making precision, and long in service life.

[0017] Compared with the prior art, the mold core of the molded glass of the present invention is made of a new ceramic material such as tungsten carbide, which is resistant to high temperature, is less prone to cracking, and has a thermal expansion system of almost zero. The metal substrate has the disadvantage of not requiring the required precision due to the large coefficient of thermal expansion, and the Neoceram material required for the mold has a lower price than the tungsten carbide and has good processing performance. In addition, the installation of a cheap metal core inside the substrate can save Neoceram materials and further reduce costs. [Embodiment] Referring to the first drawing, the mold core 1 of the molded glass of the present invention is composed of a substrate 1 'metal core 20 and a protective film 30. The material of the [(5)19] substrate is a new ceramic material Neoceram, which was used by Nippon Electric Glass Co. Ltd. to manufacture electronic source components and glass devices, which have been deposited by Beta Stone. The 'Neoceram material is very resistant to high temperatures' when the temperature reaches 10 0 〇t', it can produce no cracks, it has a zero thermal expansion coefficient, and the Neoceram material has good processability and is easy to process into the desired geometry. The inside of the substrate 10 includes a cavity 1〇1, the cavity can be tightly coupled with the metal core 20, and a protrusion 1〇2 is formed on the outside of the substrate 1 , and the protrusion 102 is provided with a molding cavity 1〇3. , molding cavity 1〇3 has 093133755 Form No. A0101 Page 6 / Total 10 Page 0993408626-0 1337175 [0020] [0022] [0023] 093133755 November 15th, 999 nuclear replacement page - molding surface m As a molded glass. The core 2 is a Japanese-made material or a gray iron, cast in the size and shape of the cavity 1G3, and then embedded in the cavity 103. The material of the protective medium 30 is 氡化烂(bn) 'It is bonded to the molding surface 104 of the molding cavity 103 by a vacuum ore-depositing method or a chemical vapor deposition method which is conventionally known in the art, and can withstand 250 (TC high temperature, protect the molding surface 1〇) 4 The surface is not damaged, and the service life of the mold core 1 is extended. The manufacturing method of the mold glass wedge comprises the following steps: firstly, a rectangular parallelepiped formed by a Beta quartz crystal body is deposited as a Ne〇Ceram material; a raised portion 1〇2; then, a molding cavity 1〇3 is formed at the top end of the convex portion 102, and the precision and shape of the molding cavity 1〇3 are required to meet predetermined design requirements; The center of one end of the starting portion 102 is hollowed out to form a cavity 1〇, and a metal core 20 is tightly coupled with the cavity 101; finally, a boron nitride (BN) protective film 30 is plated on the surface of the molding cavity 1〇3. Here, a vacuum sputtering method or a chemical vapor deposition method is known in the art. Through the above steps, a mold core having a low manufacturing cost, high molding precision, and long service life can be formed. The glass-making mold is made of a new ceramic material Neoceram which is resistant to high temperature and is not easily cracked, and its thermal expansion system is almost zero. Instead of metal such as tungsten carbide, it can avoid the metal substrate from having a large thermal expansion coefficient and failing to achieve the required precision. The shortcomings, and the Neoceram material required for the mold is lower than the tungsten carbide, and the processing performance is good. In addition, a cheap metal core is placed inside the substrate, which can save the new form number A0101 Page 7 / 10 pages 0993408626 -0 1337175, November 15, 099 E Correction of the replacement page ceramic material, further reducing costs.
