Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mold suitable for molding foods, ornaments, souvenirs and the like having a two-dimensional uneven pattern on its surface, and more particularly to a method for producing a mold having a two-dimensional uneven surface. It is.

[0002]

2. Description of the Related Art In the field of food processing, chocolate and baking dough are molded into a fixed size and shape by a mold. In the synthetic resin molding field, synthetic resin is injected into a mold and molded into a fixed size and shape. It is well known.

[0003] Among these molds, an open mold is capable of filling a material without particularly applying pressure, and is suitable for producing a large number of molded articles of a certain size and shape by demolding after curing. In addition, a mold in which unevenness for forming an uneven pattern on the surface of a molded product is formed on the inner surface is often used.

The above molds are usually made of metal to withstand multiple uses over a long period of time, and both professional and domestic molds are manufactured and provided by professionals. Therefore, in a mold in which irregularities for providing a pattern are formed on the inner surface, a molded product having the same irregular pattern is always produced.

[0005]

However, foods, decorations, souvenirs, etc. having irregular patterns suitable for these are used for hobbies or commemorations of celebrations and events in individuals and groups using molds. In some cases, the use of expensive metal molds for temporary use by professionals places a significant economic burden on the general public.
In addition, making a mold by forming a textured pattern on a metal requires considerably limited equipment and a high degree of expertise, and is not suitable for use for a temporary or a small number of molded articles. . Furthermore, it is also difficult to respond to various demands for expressing people, animals and plants, landscapes, paintings, patterns, figures, characters, and combinations of these with uneven patterns.

[0006] The present invention has been made in view of such circumstances, and uses a readily available raw material and equipment that can be operated by ordinary people without requiring a high level of specialized skills, to provide a temporary solution. Another object of the present invention is to provide a molding die that can easily produce a small number of molded products having various uneven patterns.

[0007]

In order to solve the above-mentioned problems, the present invention provides (1) a method in which image data of a document having an uneven surface is input to a computer by an image scanner, while a substrate having a desired size and shape is provided. (2) setting the board on the engraving machine, making a two-dimensional engraving on the surface of the board according to the operation instructions output by the computer based on the image data, and (3) engraving the model. (4) Separating the model from the molding material, leaving the surface opposite to the surface on which it is rubbed, and (4) separating the model from the molding material to form an open top surface with irregularities corresponding to two-dimensional engraving on the bottom surface. And forming each of the molds having the above-mentioned points, which includes the steps (1) to (4).

Gypsum is a very common raw material for arts and crafts, and can be easily cut and excavated using a blade. However, when a mixture with water is put into a mold and cured to form a substrate of a desired size and shape, the water content decreases in a short time and the material becomes brittle, so that chipping easily occurs, and fine engraving is performed. I am worried that I cannot do it. Therefore, a relatively coarse engraving may be used, but a fine engraving is desirably applied within a period of time immediately after curing, when the moisture content is large.

[0009] However, in the actual work, the time between the substrate manufacturing and the engraving work varies widely, so that either or both of synthetic resin powder, glass fiber and asbestos short fiber are mixed into gypsum as a reinforcing material. It is preferable to use the one obtained. These reinforcements reduce the brittleness of the gypsum and allow fine engraving even after a long period of time after curing. In addition, what mixed the synthetic resin powder can use the commercial item known as resin gypsum.

Next, in the present invention, as a manuscript for creating a pattern to be revealed by unevenness, any one expressed on a plane such as a photograph, a picture, a pattern, a figure, a character, etc. can be applied. The image data selected according to the purpose and application is AD-converted by an image scanner and input to a computer, generally a personal computer.

At this time, the original may be input as it is. However, in the case of a photograph, the original is copied by a copying machine, and in the case of an original which needs to be enlarged, reduced or corrected, the original of a desired size is copied by the copying machine. The user is required to make a copy or to make necessary corrections such as additions and deletions to the copy before inputting. still,
A document can be displayed on a display device based on image data input to a computer, and correction and editing can be performed on the screen.

The engraving machine is a commercial product for arts and crafts in which a blade or a substrate is moved in a two-dimensional direction to perform engraving, and the movement of the blade or the substrate is computer-controlled.

The substrate is set in such an engraving machine, and engraving is performed on the surface of the substrate in accordance with an operation instruction output from a computer based on the input image data. At this time, blade control data for adjusting the engraving depth according to the area is input to the computer so that the depth of cutting and excavation by the blade varies depending on the location, and based on the image data and the blade control data. By following the operation instructions output by the computer, it is possible to form a two-dimensional sculpture having various and complicated three-dimensional effects on the surface of the substrate.

When the required engraving is performed, the engraved substrate is removed from the engraving machine, and if necessary, the model is obtained by manual correction. This model can be used as it is, but depending on the type of molding material, oil-based paint,
In some cases, an anti-adhesion layer is provided by applying a synthetic resin paint or the like.

The molding material has fluidity but has the property of hardening over time, and has no danger such as high temperature and harmfulness and can be safely handled by ordinary people. Preferably, a synthetic resin such as a silicone resin or a urethane resin is suitable. In particular, silicone resin is chemically inert and has excellent heat stability and mold release properties, and is one of the most suitable raw materials for a molding die for ordinary people, whose main object is the present invention.

Then, the model is placed in a shallow container having a flat bottom with the sculptured surface facing upward, and a molding material of a molding material in a flowing state is poured into the container to wrap the model. When the molding material is hardened and removed from the container, the surface of the model that was in contact with the container bottom is exposed on the surface of the molding material, so by extracting and separating this model, it can be used for two-dimensional engraving of the model As a result, a mold having cavities formed on the bottom surface and having an open top surface is formed.

The above-mentioned space may be left as it is, but it does not hinder the application of the release material depending on the type of the molded product to be injected into the space.

The desired material is filled into the cavity of the molding die formed as described above by pouring or pouring without pressurizing, and if necessary, crushed and then released from the mold to form a model. This is to obtain a molded article of the same shape.

As described above, the model and the molding die are made of gypsum,
It is possible to use easily available raw materials such as a synthetic resin, and it can be produced without requiring a high level of specialized skills. Further, copiers, image scanners, personal computers, and engraving machines are all devices that are widely spread or easily available and can be operated without requiring special technical skills.

It is possible to make a molded product from a wide variety of raw materials such as food, soap, synthetic resin, metal, etc. using the above-mentioned molding die. It is preferable from the viewpoint of safety to apply the present invention to food, soap or synthetic resin as a raw material that can be handled by the above method. Further, in this temperature range, there is no fear that the molding die is deformed, softened or melted even when the molding die is made of a synthetic resin.
