い。However, the above-mentioned prior art has the following problems. (1) When the molding surface support layer has no adhesiveness, a mold pressing jig 8 for pressing the mold from the outside is required to fix the molding surface layer 2 and the molding surface support layer 4 as shown in FIG. Therefore, the clamp 7 has poor compatibility with other types. (2) When the molding surface support layer 4 has no adhesiveness, as shown in FIG. 3, the clamping between the molding surface layer 2 and the molding surface support layer 4 is repeated even if the molding surface support layer 4 is pressed by a jig or the like. Gap 9
May occur, the mold matching position may be displaced, and a gap may be formed due to wear. (3) Even when a material having an adhesive property such as cement is used as the molding surface support layer 4, the adhesive strength is not so strong, and it tends to be nonuniform depending on the location, and easily peeled off by air blow. (4) When a material having poor planar accuracy is used for the molding surface support layer 4, sealing with the molding surface is difficult and air leakage may occur. (5) In the case of a mold having a complicated shape, it becomes difficult for the molding surface support layer to conform to the shape, a gap or the like is easily generated between the mold and the mold, and stress is concentrated due to clamping and pressure during molding.
The mold may be damaged by long-term use. (6) Since the molding surface support layer is in direct contact with the molding surface,
If a material with poor water resistance is used, it cannot withstand long-term use.

Even when fixed to, it is compatible with other types and is easy to handle. Further, since the organic adhesive layer prevents the molding surface layer and the molding surface supporting layer from being displaced from each other, the mold alignment position is not displaced and the mold is not damaged due to the abrasion of both. This organic adhesive is required to have adhesive strength that can withstand the pressure of air blowing and water resistance that can withstand a long-term wet environment, but in general, organic adhesives are more adhesive than inorganic ones such as cement and mortar. It has excellent strength and water resistance, and the material can be selected from a wide range. Specific examples include epoxy-based, acrylic-based, urethane-based, polyester-based, cyanoacrylate-based, resorcinol-based and the like.

The water resistance of the molding layer support layer is improved as compared with the case of being in direct contact with the molding surface layer. Further, the organic adhesive fills the gap between the molding surface layer and the support layer by pressing the adhesive surface at the time of bonding. As a result, even if a material that does not produce a flat surface is used as the support, or even if the shape of the mold is complicated and there is a gap between it and the molding surface support layer, there is no air leakage or stress concentration and it can withstand long-term use. ..
