DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded article with a drawn pattern and a method for producing the molded article.

[0002]

[Prior Art] Arimatsu is located in the southeast of Nagoya,
Since the Edo period, it has prospered as one of the post towns on the Tokaido.
This town is famous for its squeezed products, along with the streets preserved since the Edo period. In particular, about the latter, hundreds of Arimatsu squeezing techniques are reported.

[0003] In general, the "squeezing" is performed by using a dye in a state in which, for example, a cloth such as cotton is picked with a thread or a cloth is wrapped around a bar to form wrinkles and liquid is partially prevented from entering. Manufactured by dyeing.
Since the squeezed products produced in this way are all handmade, there is a slight difference between the creators, and it can be said that this is one of the unique works of art.

[0004]

However, since this drawn product is a fabric, it has been used and stored for many years,
Deformation and discoloration are inevitable. The inventor has over the years
It has been invented so that the "aperture" can be preserved forever, preserved in future generations, and made widely available. As a device for this, for example, there is a device in which a part of a drawn product is cut, put into a picture frame, and covered with a transparent glass plate. However, although this has a tie-dye pattern, it is impossible to leave an uneven iris pattern which can be said to be a part of the life of the iris. Moreover, it is merely an ornamental thing put in a picture frame, and it cannot be said that it is industrially usable. As a next device, there is a device in which a part of a drawn product is cut and fixed to a flat plate, and aluminum powder is deposited on the surface thereof, for example. Although this one has the possibility of eternity while leaving the uneven aperture pattern of the aperture,
High cost and hardly suitable for mass production.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a molded article having a drawn pattern on its surface and a method of manufacturing the molded article. The purpose of the present invention is to provide the diaphragm with eternity and to provide an industrially usable one.

[0006]

In order to solve the above-mentioned problems, a molded product according to the invention of claim 1 is formed from a solid material with a concave-convex pattern of a drawn product as a prototype, and formed on a surface thereof. Is characterized by having a concave-convex pattern. In the present invention, the "squeezed product" is made by processing cotton cloth, silk, wool, polyester, nylon, or the like by a known squeezing method. The “solid material” is not a cloth such as cotton but a solidified material such as a metal, a glass material, and a synthetic resin. However, it may have elasticity like rubber, for example. The “aperture pattern” includes not only a shape used as a surface material of an ordinary squeeze product but also an uneven pattern on a side usually used as a lining.

According to a second aspect of the present invention, there is provided a method for manufacturing a molded product with a drawn pattern, wherein the drawn product is fixed to a surface of a fixing member.
The method is characterized in that a mold is created by molding an uneven drawing pattern of the drawn product with a granular material, and a liquid material to be solidified is poured into the mold and solidified. In the present invention, the "fixing member" may have a curved surface in addition to a plate having a flat surface.

[0008]

According to the first aspect of the present invention, the surface of the molded article is provided with an uneven drawing pattern, and is formed of a solid material. Longer life than products. The molded article itself can be used, for example, as an ornament. Furthermore, if it is formed of a material having strength such as glass or metal, it can be used as a building material. According to the second aspect of the present invention, it is possible to manufacture a molded article having an uneven drawing pattern on the surface.

[0009]

Next, one embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 shows one of the methods for producing a drawn product from a cotton cloth or the like. The wrinkle pattern was formed on the cotton cloth 2 while the cotton cloth 2 was wound around the rod 1. This cotton cloth 2
Is immersed in the dye while wrinkled,
A squeezed product having a conventionally known tie-dye pattern and an uneven squeezed pattern is formed.

2 and 3, a part of the drawn product 3 produced in this manner is cut and a wooden flat plate 4 (corresponding to the "fixing member" in the present invention). 1 shows a state in which it is fixed to the surface. Drawing product 3
Is cut into a substantially rectangular shape, and its four sides are fixed by nails 5 at appropriate intervals. At this time, the uneven pattern 3A applied to the drawn product 3 is fixed while being maintained. In this way, the flat plate 4 having the drawn product 3 fixed on the surface is used as a prototype,
A and 6B are formed.

Next, the manufacturing steps of the molds 6A and 6B will be described with reference to FIGS. In FIG. 4, the flat plate member 4 on which the drawn product 3 is fixed is placed inside the lower casting frame 7, and the casting sand 8 (water glass or the like is mixed for solidification from above). This corresponds to the “granular material” in the present invention.) The casting flask 7 is formed in a square shape from wood, and a predetermined amount of casting sand 8 is put in the inside thereof. The plate member 4 is slightly immersed in the casting sand 8, and the casting sand 8 is sprinkled from above using a sieve.

After sprinkling a predetermined amount of molding sand 8, the molding sand 8
The molds 6A and 6B are formed by injecting carbon dioxide into the inside of the glass to harden the water glass. The molds 6A, 6A
In B, a runner 9 is formed in advance.
See). Thus, a pair of upper and lower molds 6A and 6B are formed. Heretofore, a technique of forming a mold using casting sand has been used as a mold for manufacturing mechanical parts such as automobiles and industrial products, for example. Manufacturing as a drawback means that neither the creator of the drawn product nor the maker of the mold formation can recall one another.

Next, in a state where the upper and lower molds 6A and 6B are combined, molten aluminum 11 (corresponding to "liquid material" in the present invention) is poured from the runner 9 into the space 10 in the mold (FIG. 1). 6). The molten aluminum 11 is solidified and taken out of the molds 6A and 6B, thereby forming a molded article 13 having an irregular drawing pattern 12 on the surface.
Is created. The molded article 13 may be used as it is, for example, as an ornament, or a mold for mass production may be molded using the molded article 13 as a prototype.

As described above, according to the present embodiment, the drawn product 3 provided with the drawn pattern 3A is fixed to the surface of the flat plate material 4,
Molds 6A and 6B are formed by molding the surface of the flat plate material 4 with molding sand 8, and molten aluminum 11 is poured into a space 10 inside the molds 6A and 6B and solidified to form an irregular drawing. The patterned molded product 13 is manufactured. The surface of the molded article 13 has a drawn pattern 1
And aluminum 11 which is a solid material.
, The service life is longer than that of the conventional drawn product 3 which is a cotton product. Further, the molded article 13 itself can be used, for example, as an ornament.

Furthermore, if it is formed of a material having strength such as glass or metal, it can be used as a building material.
