Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to coating a gel-like or liquid coating liquid on a running flexible strip-shaped support, or for forming a coating liquid A mold (coating mold or τ-type mold) from which the molten resin of the resin is discharged from the lip portion, and a method for producing the same. [Prior Art; 1 _] A conventional mold, for example, in the case of a coating mold, although a specific document such as a patent publication cannot be cited as an example, in a conventionally used coating mold, it is formed. A mold for a lip member made of a super-hard alloy is attached to the end side of the mold body, and a high rigidity, wear resistance and impurities are obtained by the superhard alloy of the material member. Seek to improve the shape accuracy of the tip end. [2] A resin film produced by a loosening machine using a T-die, in particular, a product used for optical (four) or the like is required to be a product having no thickness deviation or streaky defect. Therefore, as the mold flow path of the 融 a melting path, the inner wall surface must be designed to be smooth without stagnation, and in particular, the lip portion of the effusion (four) material must be formed into a sharp edge at the tip end portion thereof. And in order to design it into a technology that does not suffer from the cost of wear and tear, it must be formed by materials with high hardness or (4) high consumption, which is expected by everyone. _In the conventional technique, 'the hard wall bond is applied to the inner wall surface of the mold flow path in order to reduce the friction with the molten resin, and on the other hand, it is proposed that the wear resistance is in the form of °°°卩High super-hard alloy powder, by example h heat-solubilized @coated scheme ° but 'on the inner wall surface of the mold flow path 100118938 Form No. A0101 Page 3 / Total 45 pages 1003260714-0 201201992 Gold = τ over When you want to apply a lip-like "overcoat" to the super-hardness = the anterior hard chrome recording of the apex, the film is "cracked" and the crack occurs in the coating. This is the formed tree ==_ Therefore, after the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ There is a hindrance to the resin, and it is caught. In addition, in the case where the superhard alloy powder is coated by thermal spraying, (4) the 峨 is used as a domain _ hard powder material is melted and sprayed, so it is performed after the spray. Grinding and grinding to complete the edge of the edge, it is easy to peel off the particles of the powder material [0005] Here, the lip-shaped county is formed of a super-hard alloy, and the mold which is mounted to the mold body is proposed as a conventional solution. #Install the lip of the super-hard alloy to In the case of the mold body, not only peeling or cracking as described above is produced, but also high abrasion resistance, corrosion resistance, and strength can be obtained. [Invention] [0006] However, a lip made of a superhard alloy as described above When the mold is attached to the mold body, fine pores remain in the sintered body. When the crystal is ground, 'there are many pinholes, so there is a problem in surface roughness, which cannot be used. In addition, the lip-shaped member made of a superhard alloy is bonded to the mold body as a base material by welding or welding, so that In the joint, there is a large joint wear due to the weld defect or the weld 100118938 Form No. 1010101 Page 4 / Total 45 Page 1003260714-0 201201992 In the same manner as described above, it is not possible to use a manufacturing process such as a liquid crystal display panel that requires high precision. Further, when the molten resin is discharged from the lip portion to form a resin film, it is impossible to make a thin film. In view of the above, in place of the above-mentioned case, the lip member made of a superhard alloy is used by HIP (short for Hot Isostatic Pressing, the so-called hot equalization method). The treatment is directly diffused and bonded to the lip portion of the HIP layer on the substrate of the mold body, whereby the structure of the lip portion is densified, and the surface roughness can be completed with high precision. The strength reduction of the joint portion or the joint defect does not occur, and the edge can be made into a sharp edge with a precision to provide a mold (coating mold and τ-type mold) having a lip portion excellent in abrasion resistance and corrosion resistance. And its manufacturing method for the purpose.

On the side, the hard chrome ore coating 50 to be coated and the HIP layer 40 are cut in the same plane. In the plane view of (a) of Fig. 12, the final line of grinding is indicated by 〇, and the hard chrome plating layer 50 and 1111> layer 4 切削 are cut up to the line 6, whereby, as shown in Fig. 12 As shown in (b-1) and (b-2), the hard chrome plating layer 50 on the inner surface side of the mold materials 42 and 43 can be formed in the same plane as the 111-layer 4 形成 formed as the lip portion 36. After that, mirror grinding or mirror finishing should be required. The entire inner surface side of the mold materials 42 and 43 and the part of the hip layer 40 are undercut, and the hard road plating layer 5 is slid across the entire inner surface side of the mold materials 42 and 43 and the HIP layer 40. After that, a part of the hard chrome plating layer 5 on the inner surface side of the mold materials 42 and 43 is cut in the same plane as the HIP layer 40 formed as the lip portion 36, whereby the inner surface side of the mold material is The hard chrome plating layer or the electroless nickel plating layer 5 〇 and the HIP layer 40 formed as the lip portion 36 are all smoothly formed without causing a gap or peeling phenomenon therebetween, and undergoing It can still be used stably for a long period of time. 100118938 Form No. A0101 Page 23 of 45 1003260714-0 201201992 [0066] As described above, the HIP layer 4G finishing layer 50 of the complex layer 5 of the inner surface of the mold elements ', 42, 43 is After the lips are in the same plane, the mold materials 42 and 43 are mirror-finished (including polishing) into the required shape, θ, forming the upper mold structure (4) and the lower mold structure (4) of the coating molding. In the member 33, a coating liquid supply path and a difference are formed: (c) in Fig. 12 shows that the upper mold member 32 and the lower loose member 33 face each other to form the mold main body 34, and the mold main body 34 is formed. The mold flow path 35 is formed in the inside, and the coating die 41 is manufactured by forming the lip portions 36 and 36 on the tip end side of the mold flow path. W7] According to the method of the present invention, in order to manufacture the tau mold 31 and the coating The mold 41 is basically HIP-treated and hard with respect to the mold materials 42, 43 as shown in the embodiment of the method of manufacturing the coating die 41 described in the first to the twelfth drawings. After the chrome plating treatment, the shape processing of the entire mold material 42 and 43 is performed. The final shape of the coating die 41 is formed, but the shape processing may be performed before the HIP treatment and the plating treatment. In this case, the residual of the HIP layer 40 on the mold materials 42 and 43 and the hard chrome are calculated. After the residual state of the plating layer 50, there is a need for shape processing. [0068] As described above, before the hard chrome plating treatment, the shape processing of the material containing the HIP layer 40 portion is performed to manufacture the T-die. 'When machining or grinding is completed from the resin flow port to the tip end edge of the outflow port, hard chrome plating is performed. In this case, the residual amount of the hard chrome plating layer is considered, and plating treatment is performed. Pre-machining or grinding (refer to (b-1) and (b-2) of Fig. 11). After hard chrome plating, see (b-1) and (b-2) in Fig. 12. ) Description - 100118938 Form No. A0101 Page 24 / Total 45 Page 1003260714-0 201201992 Sample, the hard chrome plating layer 50 and the HIP layer 4 〇 are ground in the same plane, and then mirror grinding, mirror surface Grinding can be done. In addition, the shape of the second element The manifold portion or the molten resin, or the flow portion of the coating liquid, or the hard chrome plating treatment portion can be mirror-finished by polishing. [0069] According to the invention as described above The T-die or the coating die ο, because the lip portion 36 of the mold body 34 is treated by the hip, and the alloy powder having good resistance and wear resistance is bonded to the substrate of the mold body. The HIP layer 40 is formed by diffusion bonding of the HIP layer 40 at an arbitrary thickness. Therefore, the structure of the lip portion 8 is densified by the HIP treatment of the alloy powder, and the inside of the lip portion 8 is not formed like the sintered body of the cemented carbide. Residual pores, pinholes do not occur during grinding or grinding, and strength reduction or joint defects of the joint portion do not occur, and the surface roughness of the lip portion 36 is greatly improved, and the edge portion can be used as the edge portion. The lip 47 of the lip 36 is completed as a sharp edge of 1 unit. Therefore, the surface roughness of the lip portion 6 can be completed on the lip port 47 which is the edge portion of the lip portion 36 until it reaches Ry〇.1 //in'. Further, when the grinding is completed, further Refine the surface roughness. Further, assuming that the mold flow path 35 of the mold main body 34 is entirely formed by the HIP layer 40, the manufacturing cost of the mold becomes extremely high, but the molds 31, 41 according to the present invention are only the lip portion. 36 is formed by the HIP layer 40, and the inner wall surface of the mold body 34 which forms the mold flow path 35 other than the lip portion 36 is coated with an extremely inexpensive hard chrome plating layer. Therefore, it is possible to reduce the manufacturing cost of the mold. 100118938 Form nickname A0101 Page 25 of 45 1003260714-0 201201992 [0071] Since hard chrome plating is used, the friction coefficient is small and the smoothness is very good, other substances are difficult to adhere, and rust-proof plating is possible. The coating can reduce the friction between the molten resin and the coating liquid. Even when a molten resin or a coating liquid having high friction is used, the 'liquid contacting portion of the mold flow path 35' does not occur. It can be used for a long time. [0072] Further, since the lip portion 36 is formed by HIP treatment, the HIP layer 40 which is diffusion-bonded to the substrate of the mold body 34 at an arbitrary thickness is formed, so that it is superhard to be mounted. When the lip portions formed of the alloy products are compared, the joint strength with the base material is extremely large. Further, since the HIP layer 40 forming the lip portion 36 has a thickness of at least several millimeters to several tens of millimeters, it can be reused by repair grinding, and the processing can be performed a plurality of times until the HIP layer 40 disappears. Hard chrome wrap can be restored at a cheap price. [0073] In the above embodiment, the inner wall surface of the mold body 34 forming the mold flow path 35 other than the lip portion 36 is replaced by the hard chromium plating layer 5, but instead of the hard chromium plating The layer 50' may be formed by an electroless nickel plating treatment to form an inner wall surface of the mold body 34 other than the lip portion 36, and a nickel plating layer may be formed thereon. The electroless nickel plating treatment refers to the treatment of mineral coating without using electricity. Since the film thickness of the ore coating can reach the uniformity, it is only necessary to impregnate the plating solution, and is suitable for products having complicated shapes and dimensional precision. . The plating layer formed by the electroless nickel plating treatment has good adhesion to the substrate. The thickness of the plating film can be uniform, and the wear resistance is equivalent to that of the hard core bonding layer 50. Sex, and corrosion resistance is also often excellent.
