Description of the invention: [Technical field of the invention] [0001] The present invention relates to a mold core, and more particularly to a mold core having a protective layer and a preparation method thereof. [0002] • [Prior Art] Molding is widely used in the molding process, especially in the manufacture of optical glass products, such as aspherical glass lenses, ball lenses, prisms, etc., which can be directly produced by Direct Press-molding technology. Optical glass products, without the need for subsequent processing steps such as grinding and polishing, can greatly improve production efficiency and yield 'and good product quality. However, the direct compression molding method requires high chemical stability, thermal shock resistance, mechanical strength, and surface smoothness of the mold core. Therefore, the development of compression molding technology actually depends on the advancement of mold core materials and mold manufacturing technology. For molded parts, there are generally the following requirements: [0003] (1) Good temperature resistance to mechanical shock strength and hardness at room temperature » # [0004] (2) Thermal shock in repeated and rapid heating and cooling The lower mold core does not cause cracks and deformation; [0005] (3) At high temperature, the molded surface of the mold does not chemically react with the optical glass, and does not adhere to the glass; [0006] (4) High temperature oxidation does not occur; [0007] (5 ) Good processing performance, easy to process into high precision and high surface finish profile 9 [0008] 094107455 (6) Low cost. Form No. 1 ^ 3 17 I 1003377417-0 1360525 [0009] [0011] [0013] 094107455 October 13, 100 nuclear replacement page traditional mold core mostly using stainless steel or heat resistant alloy as a mold The material, the mold is prone to high temperature oxidation, and under repeated thermal shock, grain growth will occur, and the surface of the mold will become rough and the glass will be bonded. In order to solve the above problems, non-metal and super-hard alloys are used for the mold core. It has been reported that carbon carbide (SiC), nitrite (si3N4), titanium carbide (TiC), tungsten carbide (WC) and tungsten carbide-ing alloy have been used to manufacture mold cores. However, the above various carbide ceramics have a very high hardness and are difficult to process into a desired shape, particularly a south precision aspherical shape. In addition to being difficult to process, superhard alloys may undergo high temperature oxidation after a period of use. Therefore, it is a new development direction to use carbide or super-hard alloy as the base of the mold, and the composite structure with other materials coated or coated on the surface has become a new development direction. Typical composite structures are disclosed in U.S. Patent Nos. 4,685,948 and 5,202,156. U.S. Patent No. 4,685,948 discloses a composite structural mold for direct compression molding of optical glass products. It uses a high-strength super-hard alloy, carbide ceramic or cermet as the base of the mold, and forms an iridium (Ir) protective layer on the molded surface of the mold, or iridium (Ir) and platinum (pt), 铢 (Re ), alloy protective layer of bismuth (Os), cobalt (Rh) or nail (Ru), or ruthenium (Ru) protective layer 'or ruthenium (Ru) and molybdenum (pt), ruthenium (Re), hungry (〇s) , alloy (Rh) alloy protective layer. U.S. Patent No. 5,202,156 discloses a method of preparing a composite structural mold for use in an optical glass product. It uses high-strength super-hard alloys, carbide ceramics or cermets as the base of the mold, and forms a diamond-like film on the molded surface of the mold core (DLC, Diamond Like C^fborO, page number No. A0101, page 4/total l7 1003377417-0 1360525 Correction of the replacement page protective layer on October 13th. [0014] The protective layer of the above-mentioned composite structure mold can prevent adhesion between the base of the mold and the formed body, and prevent the surrounding from being formed. The action of oxygen in the gas causes the performance of the matrix of the mold to deteriorate. However, when the protective layer is formed, it is necessary to first grind the matrix of the mold and then apply a protective layer. If the release is easy, the molded product is intended to be molded. The surface to be contacted should have a suitable surface roughness (about 2. 2~1. 2μπ〇. Because the roughness is too low, it is not easy to remove the film.) If the roughness is too high, it will affect the shape of the molded body. • In order to achieve the protective layer This roughness range, so the surface of the matrix of the mold must also be ground to this roughness range. However, the roughness of this grade requires the use of a larger number of abrasive tools, and the result is a mold. The surface layer of the base produces a processing metamorphic layer', which greatly reduces the strength and durability of the mold. [0015] • As shown in the first figure, the application of China No. 1 139835. 3, published on July 3, 2002 A mold core 10 is disclosed. The base 丨丨 forming surface of the mold core forms an intermediate layer 12 having a thickness of 2 to 5 μm, and the intermediate layer 12 is a platinum-silver alloy layer; the surface of the intervening layer 12 is covered with a platinum film 13, The rough surface of the platinum film 13 in contact with the formed body is larger than the surface roughness of the mold base & and the surface of the platinum film 13 has a thick chain of 〇21 2 . However, the platinum film used in the mold core is used. And the cost of the platinum alloy is too high. [0016] In view of this, it is necessary to provide a mold having a good release property and a long service life, and a preparation method thereof. 0017] The following 'will be described in several embodiments - a mold which can reduce cost and has good release property and long service life. 094107455 Form No. A0101 Page 5 / Total π Page 1003377417-0 1360525 [0018] [0019 [0020] [0025] [0025] [0025] [00 [0028] [0028] [0029] [0032] 094107455 October 13th, 100th, the child is replacing 100 and through these examples to illustrate a cost reduction, and good release properties and use A method for preparing a long-life mold core.

Compared with the prior art, the mold of the present invention replaces the precious metal film structure with a plurality of intermediate layers and a diamond-like layer structure, thereby reducing the cost. In addition, the mold core is rough due to the surface roughness of the diamond-like surface. Form No. A0101 Page 6 / Total π page ^03377417-0 1360525 100 years.

Therefore, the service life of the mold core can be prolonged. The diamond-like carbon layer 24 has a high hardness value and a low friction coefficient, and can satisfy the requirements of the mold core. The surface roughness of the outermost layer of the diamond-like layer 24 is about 2.2~1.2μπι. The mold layer having the thickest range of the outermost layer has a better performance. If the roughness is less than 0.2 μm, the step body is not easy to release the film. If the roughness is greater than 1.2 μm, the mold pressure is easily affected.

The pure graphite rod target was replaced by a titanium metal target, and the first flow rate was controlled by 3~20xl〇_3Tori•. The mold base 21 set in this step has a bias range of -50V to i50V. Through this step, a diamond-like layer 24 having a thickness in the range of 0.5 to 3 μm can be formed on the surface of the titanium nitride diffusion barrier layer 23. [0045] The controller 47 is introduced with methane gas to bring the pressure of the vacuum chamber 41 to step 600, and the mold core 2 of the diamond-like layer 24 is placed in a heating device (not shown) for heating. The surface roughness of the outermost layer of the diamond is 〇·2~1. 2μιη » In the heating device, the mold core 20 is heated to 200-300 degrees, while argon gas and nitrogen gas are introduced, and the temperature is maintained. 2〜1. 2μιη 〇[0047] [0047] [0046] [0046] [0046] [0046] [0046] [0046] 094107455 It can be understood that the mold base of the technical solution can be made of stainless steel or tantalum carbide in addition to the hard alloy such as tungsten carbide; the adhesive layer is made of chrome metal material in addition to titanium metal. In the preparation method of the mold of the present invention, in addition to the sputtering method, the adhesion layer, the diffusion barrier layer and the diamond-like layer may be deposited by chemical vapor deposition, wherein the sputtering method includes bias reactive sputtering, radio frequency flooding. Shot and total money shot ° The mold of this technical solution uses a multi-layer intermediate layer and a diamond-like layer structure to replace the precious metal film structure, thereby reducing the cost. In addition, since the surface roughness of the diamond-like outermost layer is larger than the rough surface of the surface of the mold core, the surface roughness of the diamond-like outer surface layer is kept within the range most suitable for stripping (Ο.2'" ;1;.111); and the surface roughness of the surface of the mold core is less than 〇.05μΙΠ, and no serious processing changes will occur during processing.
