Description

Detailed Description of the Invention <Industrial Application Field> The present invention uses a thin elastic mold to produce three-dimensional Chiyocolate products having arbitrary wall thicknesses and arbitrary shapes, more specifically bowls, baskets, and vessels. The present invention relates to a manufacturing method for manufacturing hollow-shaped or container-shaped thiokolate products such as plates and jars.

<Conventional technology> The manufacturing method of Chiyocolate using a conventional mold is as follows:
Most of the molds use hard, solid molds made of plastic materials such as polycarbonate and PVC plates, and metal materials such as stainless steel and gun metal, and some use silicone rubber, which has some elasticity, for prototyping. Chiyocolate was manufactured using solid molds.

If a single mold is used in this way, the product will be a relief-like product or a semi-solid product, and in order to make a three-dimensional product, a method using a combination mold that combines the single molds is required. However, in the combined mold method, thiokolate is poured into each single mold, cooled for an appropriate period of time, and after the thiokolate has solidified to some extent on the inner surface of the mold, the molten thiyocolate is poured out of the mold.
After that, the individual single molds are completely cooled and solidified, making it impossible to mold them into arbitrary wall thicknesses and inner shapes. In addition, in the method of setting the mating mold on a spinner and molding the die by centrifugal force, the wall thickness can be determined by calculation, but the product must be completely hollow in shape, and must have a reverse taper or It has been impossible to arbitrarily vary the wall thickness and to manufacture products with patterns on the inner surface.

Furthermore, in order to mass-produce such a single model, a mold is created from the prototype, and this mold is used to perform the molding process.
I made the necessary amount of molds.

<Problems to be solved by the present invention> In the conventional manufacturing method of Chiyocolate using a mold, it takes a long time to determine the design and obtain the mold, and a large amount of initial work is required to manufacture the mold and the mold. Yarukosuto was needed.

Furthermore, because the mold is manufactured by machining and because the mold is solid, there are significant restrictions on the shape of the product.

However, in response to the diversification of consumer needs in recent years, there is a demand for new products that meet conditions such as high-mix, low-volume production, or fewer restrictions on design, and production starts at low cost and in a short time in terms of delivery time and cost. There was a desire to provide a manufacturing method that would allow for this.

<Means for Solving the Problems> The present invention uses an elastic material having high elasticity to form a product between an inner molded wall with an open bottom surface and an outer molded wall with a filling opening in the upper part. A thin elastic mold with stretchability is formed by having a predetermined gap with a wall thickness of After cooling and solidifying, this is demolded.

<Function> The present invention uses the above-mentioned means to shorten the time and cost required for manufacturing molds for manufacturing Chiyokolate, and also to produce Chiyokolate of arbitrary shapes and patterns on the inner and outer surfaces, which were not possible with conventional technology. It became possible to manufacture products.

<Example> An example of the present invention will be described based on the drawings.
Thin elastic mold A is made of an elastic material with high elasticity, such as natural rubber latex or synthetic rubber such as silicone rubber, urethane rubber, butadiene rubber, etc., and is made into a thin plate using the same mold as the product B to be manufactured. A gap b having the thickness of product B is formed between the inner molded wall a ₁ and the outer molded wall a ₂ by thermal deformation processing of the elastic body or dipping method of liquid elastic material. The inner molded wall _a1 forms the inner surface of the product B, which has a hollow shape or a three-dimensional container shape, and is formed into an inverted container shape with an open bottom surface and a closed top surface, and the wall _a1 has unevenness. It is possible to configure any three-dimensional pattern such as a shape, wave pattern, pattern, etc., and the outer molded wall _A2 forms the outer surface of the product B, and the outer periphery of the inner molded wall _A1. The upper part thereof is located above the upper surface closed part of the molded wall a ₁ and has a filling opening 1 for filling the thiokolate material B', and an expanding piece 2 is provided on the outer peripheral edge thereof. This wall a ₂ also has an arbitrary three-dimensional pattern such as an uneven pattern, and the lower ends of both walls a ₁ and a ₂ are connected,
A gap b having the thickness of the product B is provided between the walls a ₁ and a ₂ .

A thin elastic mold A having the same inner and outer shapes as the product B to be manufactured is made from a master mold, but it has a thickness and elasticity that can hold the shape.

A mold support plate is fixed to the expansion piece 2 of this mold A to make it easier to handle.
Pour the thiokolate material B' into the gap b using a piping bag or depositor, pour it to a position above the upper surface of the inner molded wall _A1 to fill the gap B, and then store it in a refrigerator or cleaning tunnel for a predetermined period of time. The mixture is cooled in a freezer such as a freezer to completely solidify the thiokolate material B′.

After that, this solid product is demolded, that is, removed from the mold to obtain product B. This demolding method may be performed manually, mechanically, or automatically. In the case of a simple shape, from mold A to product B
However, if the shape makes it difficult to simply pull out, for example, if the filling port side, which is the bottom of product B, has a smaller diameter than other parts, or if the top end of the product is bent or curved inward. In such a case, the filling port 1 can be expanded by pulling the expansion piece 2 to take it out, or alternatively, the inner molded wall a ₁ can also be pulled downward from the open bottom part of the inner molded wall a ₁ before being taken out. It is something that can be done. Although not particularly limited in the present invention, as an example, the filling port 1 is expanded by pulling the mold support plate fixed to the expansion piece 2 from side to side, and the tyokolate suction pad X and the mold Y are opened. After adsorbing and holding the product B and the molding wall A ₁ respectively using Pour B′ and repeat this process. This thin-walled elastic molding can be repeated until fatigue failure occurs within the elastic limit.

Furthermore, the shape of the mold and the demolding process are not limited to those shown in the drawings, and although one mold is used in the illustration,
It is natural to install a large number of units in series for mass production and manufacturing of a wide variety of products.

<Effects of the Invention> The present invention uses a stretchable thin-walled elastic mold having a predetermined gap corresponding to the thickness of the product between an inner molded wall and an outer molded wall, and fills the gap from the upper filling port. By pouring the Chiyocolate material, filling it in a predetermined amount, cooling and solidifying it, and then removing it from the mold, it is possible to create arbitrary shapes with three-dimensional patterns such as unevenness on the inner or outer surface, which was impossible with conventional methods. It is possible to produce Chiyokolate products of 1,000 yen, as well as hollow three-dimensional Chiyokolate products with arbitrary wall thickness.

In addition, the manufacturing time and cost of molding molds can be shortened.
In addition, the manufacturing process for thiyocolate can be considerably shortened compared to conventional processes, and has great economic merits.

Furthermore, in the Chiyocolate industry, Chiyocolate products are generally sold in paper boxes or plastic containers, and the cost of auxiliary materials exceeds the cost of Chiyocolate materials. It also has commercial value, and it is also possible to assemble other Chiyocolate products into it, and we can expect side effects such as being able to develop product sales that meet consumer needs. becomes possible.
