常に高価であり、製造コストが高くなる。[Prior art and its problems] Shoes are generally manufactured using a last called a wooden last, but when making so-called custom-made shoes, skilled workers use their experience and expertise to determine the foot dimensions. Based on the measurements, a standard open mold prepared in advance is corrected, and the corrected last is used to manufacture a specified shoe. However, this method has the disadvantage that it is difficult to make shoes that fit the foot perfectly, and that productivity is low and costs are high. There are also devices that can automatically measure foot dimensions, but these devices are very expensive and require high manufacturing costs.

First, as shown in FIG. 1a, a thin cover 2.3 is tightly attached to the surface of the mold pattern 1 to cover it. The model pattern 1 is, for example, an actual foot, and the cover 2.3 is, for example, a sock or the like that closely fits the foot shape. When applied to the foot, two types of covers are prepared, and the cover 2 covering the inside should preferably have the function of protecting the foot from the resin without causing the resin to come into contact with the foot. In addition, the cover 3 that covers the outside has a thickness that can cover the shrinkage of the resin when it is filled into the manufactured formwork, and it also has a thickness that can be used to harden the resin (for example, ultraviolet irradiation, light irradiation, heating, etc.). ) is suitable, having the function of protecting and tightening the skin.

A curable resin 4' is applied or impregnated onto the surface of the mold pattern. Examples of the curable resin include ultraviolet curable resins, photocurable resins, thermosetting resins, etc. Among these, ultraviolet curable resins are particularly suitable because they can be cured in a short time at room temperature. For this ultraviolet curable resin, for example, an epoxy resin prepolymer is reacted with acrylic acid or methacrylic acid,
Examples include a water-soluble compound in which a vinyl double bond is introduced into the molecule, or a water-soluble compound in which a phosphoric acid group is further introduced by reacting an epoxy resin prepolymer with acrylic acid or methacrylic acid. Furthermore, other conventionally known ultraviolet curing resins can be used. A resin having such a composition is cured in a short time by ultraviolet irradiation in the air. Conventionally known resins can be used as the photocurable resin, thermosetting resin, and the like. Methods for coating with these resins include a method of applying by spraying, a method of immersing the mold pattern in a resin solution, and the like. When applying the spray method, the resin can be coated uniformly,
Further, it becomes possible to perform the first spraying step and the subsequent resin curing step continuously in the same equipment.
つぎに被覆された硬化性樹脂を従来公知の手段を用いて
紫外線硬化、光硬化又は熱硬化する。Next, the coated curable resin is cured by ultraviolet rays, light, or heat using conventionally known means.
ついで第２図に示すように、硬化した樹脂型枠４から型
原形１を取出す。取出し方法は特に限定されないが、例
えば型原形を内側のカバー２とともに取出す方法、ある
いはカバー２又は３に切断用糸を取付けておいてこれを
引いて樹脂を切断し、型原形１を取出す方法などがあげ
られる。Next, as shown in FIG. 2, the original mold 1 is taken out from the cured resin mold 4. The removal method is not particularly limited, but for example, a method of taking out the mold pattern together with the inner cover 2, or a method of attaching a cutting thread to the cover 2 or 3 and pulling it to cut the resin and removing the mold pattern 1. can be given.
このようにして得られた型枠５は、型原形の形状に正確
に対応しており、ここに樹脂を充填することにより、足
型を製造することができる。この樹脂としては、加工収
縮率が小さく、低融点のものがよい。例えば、エチレン
ビニルアセテート樹脂は圧縮成型収縮率が０．００７乃
至０．０１２０ｍ／Ｃ１と小さく、酢酸ビニル量が３３
％で軟化点が４０℃と低く、好適である。またこの樹脂
に更にガラスを入れることにより圧縮生成収縮率を下げ
ることができる。The mold 5 thus obtained corresponds precisely to the shape of the original mold, and by filling it with resin, a foot mold can be manufactured. As this resin, one having a small processing shrinkage rate and a low melting point is preferable. For example, ethylene vinyl acetate resin has a small compression molding shrinkage rate of 0.007 to 0.0120 m/C1, and the amount of vinyl acetate is 33
%, the softening point is as low as 40°C, which is suitable. Further, by adding glass to this resin, the compression shrinkage rate can be lowered.
充填した樹脂が硬化した後、これを足型に成型し、所定
形状に切削加工して例えば第３図に示すごとき足型６が
製造される。なお型枠の表面が平滑になるように処理さ
れている場合（例えばスプレー法で硬化樹脂を塗付した
場合）は、型枠を特に取外す必要がない。After the filled resin has hardened, it is molded into a foot last and cut into a predetermined shape to produce a foot last 6 as shown in FIG. 3, for example. Note that if the surface of the formwork has been treated to be smooth (for example, when a cured resin is applied by a spray method), there is no particular need to remove the formwork.

の悪影響を受けるのを防止することができる。According to this embodiment, compared to conventional methods, it can be manufactured by so-called spot matching, and there are extremely few errors.
It is also possible to reproduce the fine details of the foot shape. This makes it possible to manufacture shoes that perfectly fit the customer's feet. Moreover, the method of making the mold is extremely simple, does not require any skilled technique, and can be handled as part of the customer service work at a shoe store. Furthermore, no expensive equipment is required, and manufacturing costs can be significantly reduced. In addition, this method is simple in its operation, and each step can be performed in succession, so the formwork can be manufactured in a short time. Furthermore, since the resin is applied and impregnated after covering the mold pattern with the cover, even if the mold pattern is a foot, it is possible to prevent the resin from coming into direct contact with the foot or being adversely affected by ultraviolet rays or the like.
なお上記実施例では、足型について説明したが、本発明
はこれに限らず樹脂にて製造可能な型枠であればどのよ
うなものにも適用できる。In the above embodiments, a foot mold was described, but the present invention is not limited to this, and can be applied to any mold that can be made of resin.
