Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a method of manufacturing a mold imitating a part of the human body shape used in manufacturing shoes, gloves, wigs, hats, medical corsets, etc.

0002

[Prior Art] Conventionally, when shoes are made to order to fit an individual's foot, the manufacturing method is based on the shape of the landing surface of the foot, the maximum foot width, and the cross-section of the instep height. The most suitable one was selected from among them, a portion of the wooden pattern was modified and supplemented, and then leather was stretched over it and sewn. Therefore, at the stage of determining foot size, not only do shoemakers have different skills, but also the areas of the foot that can be measured are limited, making it difficult to obtain detailed and accurate information, and it is difficult to obtain shoes that fit exactly as desired. It was difficult to obtain. In addition, due to the rush of mechanized mass production in recent years, the number of engineers and shoemakers who can measure feet has decreased, making it difficult to meet demand in remote areas.

On the other hand, in the case of mass production through mechanization, the shoe size is determined by the length of the sole and the circumference of the instep, and shoes with several types of instep circumferences are manufactured for a given sole length. Not too much. Therefore, even if shoes were selected based on the length of the sole, there were often no shoes that matched the shoes in terms of instep height, foot width, etc. Also, strictly speaking, the shape of the left and right feet is different,
It is nearly impossible to manufacture shoes that suit each individual. Furthermore, size and design are two different things, and there are distribution limitations in preparing all sizes for various designs, so it is important to find shoes that are designed and sized according to each individual's preference. That was difficult.

Shoes are an extremely useful tool for humans who stand on two legs, and if shoes do not fit the feet, they will not only suffer physical pain, but also cause deformation of the foot skeleton and spine. In addition, he may become mentally unstable,
It sometimes caused problems in daily life.

[0005] Conventionally, when molding a part of the human body shape, stone bones and the like have been used in general, not only in wig manufacturing, etc., and the molding process is very time-consuming.

[0006]

[Problems to be Solved by the Invention] An object of the present invention is to provide engineers with the necessary shapes of human body parts in order to manufacture shoes, gloves, wigs, hats, medical corsets, etc. that are sized to fit each individual. The object of the present invention is to provide a method that allows molding to be easily, accurately, and in a short time without the need for.

[0007]

[Means for Solving the Problems] The gist of the present invention that solves the above problems is as follows: 1) A heat-shrinkable resin film is temporarily attached to a part of the human body, and the resin film is heated and shrunk. , the resin film is kept in close contact with the human body and cured while maintaining its shape, and then the resin film is peeled off from the human body to obtain a mold. 2) Method for making a mold of a part of the human body A heat-shrinkable resin molded body molded to gently encapsulate a part of the human body is attached to the part of the human body, and the resin molded body is heated and shrunk, so that the resin molded body is in close contact with the human body. A method for making a mold of a part of the human body by curing it while maintaining its shape, and then removing the molded resin from the part of the human body. 3) Injecting fluid resin into the mold and hardening it. 4) A method for making an impression of a shape of a part of a human body according to claim 1 or 2, in which a solid male mold imitating a part of the human body is obtained. 5) Method for making a mold of a shape of a part of a human body according to any one of claims 1 to 3, wherein the part of the human body to be molded is a head.

[0008]

[Operation] The method for making a mold of a part of the human body according to the present invention uses a heat-shrinkable resin film, and if the resin film is applied to a part of the human body and heated, the resin film will be It contracts and fits closely to the contours of the human body. Therefore, while maintaining that state, it is naturally cooled and hardened.
Once removed from the human body, it becomes a female mold that accurately resembles a portion of the human body. A male mold can be obtained by injecting fluidized resin into the female mold and curing it, and since the thickness of the female mold can be ignored, it can be used as it is as a male mold imitating a part of the human body. It can also be used for measuring.

[0009]

[Example] An example will be explained based on the drawings. First Embodiment (See FIGS. 1 to 3) FIG. 1 shows an example of a case where a foot impression is taken by the method of making an impression of a part of a human body according to the present invention. First, as shown in (a), a heat-shrinkable vinyl chloride resin film with a thickness of about 0.1 mm is made into a cylindrical shape, and the tip 3 is welded using a high-frequency sewing machine to make a long bag 1. A notch 7 is made along the longitudinal direction from the rear end 4 on the side to form a tabi-like shape. Next, as shown in (b), the foot part 2 is inserted into the long bag 1, and the rear end 4 of the long bag 1, which corresponds to the "kohaze" of the tabi, is temporarily fastened 5 using a stapler or the like. Using a hair dryer or the like, heat the long bag 1 from the tip 3 to the rear end 4 at a temperature of 100°C to 13°C.
By applying hot air at around 0℃ and heating it, it is possible to make 1 bag of the same length.
If it is softened and contracted, it will come into close contact with the foot 2 as shown in (c). If it is naturally cooled to room temperature in that state, the same length bag 1 will have a leg part 2.
It hardens while in close contact with the foot part 2, and becomes the female mold 6 of the foot part 2 (d
). The female mold 6 is flexible and can be easily removed by removing the temporary fixing 5 as shown in FIG. 2 or by cutting the notch 7 in the direction of further extension as shown in FIG. 3. At this time, if you wear socks or the like, you can take your feet off more easily and protect your feet from heat. Thereafter, by filling the female mold 6 with a casting resin 8 that can be treated at low temperatures and curing it, a solid male mold 9 imitating the foot can be manufactured as shown in FIG. 3(e).

Second Embodiment (See FIG. 4) In this embodiment, a vinyl chloride resin molded body, which has been previously formed into a shoe shape, is used to take a foot impression. FIG. 4 shows an example of the molded body 16. As in this embodiment, if a three-dimensional molded body is used which is shaped to a certain extent so that the foot can be gently covered, there is no need for temporary fixing, and the molding can be completed more easily and in a shorter time. Of course, when taking off the foot, it is sufficient to cut open between A and B in the figure.

[0011] If the mold-making method according to the present invention is applied to the mold-making of a foot, the mold can be taken anywhere, in a short time, and without the need for an engineer. The manufactured foot last is lightweight and highly flexible, making it easy to handle and very convenient for transportation and storage. In addition, since a very thin resin film is used, the female mold itself represents the shape of a part of the human body just like the male mold, so a craftsman with excellent processing technology can create the female mold without having to manufacture a solid male mold. It is also possible to send shoes by mail and request shoe manufacturing, which allows for rationalization of production through division of labor. When using the last obtained by the method of the present invention as a wooden last for shoe manufacturing, a solid male mold is molded using a hard resin,
All you have to do is correct it to a shape that takes into account trends and use it. Similarly, it is also easy to manufacture hand models as glove molds, ornaments, etc.

Third Embodiment (See FIGS. 5 and 6) This embodiment describes a method for manufacturing head molds for wigs and hats using the same materials as explained in the first embodiment. This is an example. FIG. 5 is a side view showing a state in which the vinyl chloride resin film is applied to the human head 10, and FIG. 6 is a front view thereof. As shown, the head 1 except for the face 11 and ears 12
The vinyl chloride resin film is formed into the shape of a bag 15 so that the vinyl chloride resin film can be applied to the entire surface of the bag 15, and the part corresponding to the face 11 is cut out and the part corresponding to the ears 12 is cut out. The human head 10 is covered with the bag 15 and temporarily secured at the chin part 14 using a clip 13. The use of the clip makes it easy to attach and detach, and is also very convenient when removing the female mold that has been closely molded onto the head. The molding process is the same as that of the first embodiment, and the bag 15-shaped vinyl chloride resin film is heated and shrunk to be brought into close contact with the head 10, and while this state is maintained, it is cooled and hardened. Note that the face 11 and the like may be covered with a mask if necessary.

[0013] Furthermore, when manufacturing medical casts, corsets, etc. using the mold-making method according to the present invention, resin films may be laminated or the film thickness may be taken into consideration as necessary. Furthermore, the mold-making method according to the present invention can be applied as a substitute for a bandage in places where it is difficult to fix with a bandage, such as an ankle. In that case, a material with cuts or holes, such as expander metal, may be shrunk and used to hold gauze or the like.

In the above-described embodiments, vinyl chloride resin films were used, but of course, any suitable film can be selected from among those that can be heat-processed, and the thickness thereof may also be set appropriately. Further, when applying resin to the foot portion, etc., the foot portion may be sandwiched between two resin films instead of being formed into a bag shape. As for the heating method, a heating wire can also be used instead of a hair dryer. Further, as a temporary fixing, it is sufficient to simply hold it by hand. Furthermore, when molding a male mold, any curable resin, foamable resin, or two-component mixed resin such as epoxy resin may be used as long as it can be poured into the female mold.

[0015]

Effects of the Invention: The method for making a mold of a part of the human body according to the present invention uses a heat-shrinkable resin film, so it adheres to the human body as a surface rather than a point or line, and can be used to form curved surfaces on soft skin. can be accurately modeled. Moreover, the entire manufacturing process takes about 30 seconds, and no other equipment or engineers are required, and molds can be easily and inexpensively taken anywhere. Furthermore, since a resin film is used, due to its highly flexible nature, there is little damage or deformation, and it is lightweight, easy to handle, and extremely convenient for transportation and storage. Moreover, since the thickness of the obtained female mold is negligible, the female mold itself represents the shape of a part of the human body just like the male mold, and the female mold can be used to express the shape of a part of the human body. can be measured. Of course, more accurate measurements can be made by making corrections according to the thickness of the resin film.
