Description

  The present invention relates to a method for producing a table coral replica, which can be produced in a mold and can produce a table coral replica that is very similar to a real table coral.

  Conventionally, smallpox has been present in dredging, but in recent years, trapping of smallpox has been prohibited from the viewpoint of environmental protection. However, in aquariums, zoos, etc., many marine animals and fish are currently on display. In this case, the demand for the table coral replication is nationwide.

  In addition, as a prior art, Patent Document 1 is authorized as a method for constructing a coral reef or a coral reef mixed with a natural coral or a replica coral. There are no patents on how to manufacture.

  Further, in Patent Document 2, there is a coral reef landscaping method, but in particular, it is a technique relating to a method for improving the underwater environment by restoring the coral reef. By the way, table coral is particularly in high demand in aquariums and the like, but it is extremely difficult to mold this table coral with a mold, not a natural product, industrially.

  The main reason for the difficulty in manufacturing is that the table coral structure prevents it from coming out of the mold. Specifically, a large number of protrusions are clustered radially on the upper surface side of the table coral, and these cannot be removed with a general mold.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. There is a table coral prototype 90 as a replica kite that is manufactured close to a natural kite. As mentioned above, in reality, catching of smallpox is prohibited, so a replica kite that seems to be close to smallpox is the prototype. Next, the manufacturing method of the table coral replica 99 and the configuration of each stage based on the table coral prototype 90 will be described.

First stage (see Fig. 1)
The table coral prototype 90 is placed on the simple pedestal 1 in parallel with the back side as the upper side, and a mixed solution of the back side silicon resin 2 is filled to a predetermined thickness on the upper side, and cured to some extent. It is also called so-called biocuring. Since only the back side silicon resin 2 is not cured, it becomes an oily mixed liquid in order to mix an appropriate curing agent.

  When the mixed liquid of the back side silicon resin 2 has a predetermined thickness, hemispherical pedestal recesses 11 are formed at a plurality of (mainly) locations on the periphery of the simplified pedestal 1, Protrusions 21 are formed around the back side silicon resin 2. Further, a peripheral wall member 15 is provided around the simple pedestal 1 so as to surround the simple pedestal 1.

Second stage (see Figure 2)
When the mixed liquid of the back-side silicon resin 2 is in a biocured state, a plurality of block-shaped solid silicon pieces 22 are also embedded in the periphery of the inner position of the peripheral wall member 15. In that state, it is filled with an aqueous solution of gypsum 3 made of calcium sulfate and appropriately dried and cured. The gypsum 3 is fluidized by mixing water, and its upper surface is flattened. This dries and cures in about 1 to several hours. When cured, the strength increases. The back side silicon resin 2 and the plaster 3 constitute a back side type F [see FIG. 3 (A)].

Third stage 1 and 2 (see FIGS. 3 and 4)
The back surface side mold F made of the back surface side silicon resin 2 and the gypsum 3 is placed on the simple pedestal 1 while being turned upside down with the table coral prototype 9 attached (see FIG. 3B). Therefore, this time, the thin plate pieces 70 facing the longitudinal direction of the projecting portions 90a are straddled between the many projecting portions 90a, 90a on the upper surface, and a large number of these are set. The presence of the thin plate piece 70 is useful for demolding (see FIG. 7C).

Fourth stage (Fig. 5)
Under such a condition, the liquid mixture of the surface-side silicon resin 4 is filled to a predetermined thickness from above the numerous protrusions 90a, 90a,. A plurality of block-like solid silicon pieces 41 (four to six) are arranged in an embedded manner around the inner position of the peripheral wall member 15 in the raw dry state.

Stage 5 (Figure 6)
In that state, it is filled with an aqueous solution of gypsum 5 and cured as appropriate. The gypsum 3 is fluidized by mixing water, and the upper surface thereof is flattened. This cures in about 1 to several hours. When cured, the strength increases. A surface side mold R is constituted by the surface side silicon resin 4 and the plaster 5. In particular, the back side silicon resin 2 and the front side silicon resin 4 are both semi-dried and attached with a gauze (not shown) for reinforcement. The gauze is embedded in silicon resin.

Stage 6 (Figure 7)
The front surface side mold R and the back surface side mold F are dried and hardened while being fitted to the table coral prototype 9. Then, the gypsum 5 is removed with the gypsum 5 in the surface-side mold R being cured to some extent [see FIG. 7B]. Next, as shown in FIG. 7C, the surface side silicon resin 4 is lifted from the end, and is removed from the numerous projecting portions 90a, 90a,.

  Such removal is possible by the soft silicon surface resin 4 and the thin plate piece 70 straddling the protruding portions 90a and 90a. That is, when the thin plate pieces 70, 70 in the state of FIG. 3 (B) are cured after filling with the surface side silicon resin 4, the resins are separated from each other within a narrow range as in the state of FIG. 4 (D). It is to become.

7th stage (FIGS. 8 and 9)
Similarly, from the back surface side mold R, the back surface side silicon resin 2 is also lifted from the end and removed from the table coral prototype 90. In this way, the rear surface side mold R and the front surface side mold F are arranged as shown in FIGS.

  At this time, the convex portion 21 of the back surface side mold R and the concave portion 41 of the front surface side mold R are configured to coincide with each other. Thereby, the positioning when the back surface side mold R and the front surface mold F are joined can be ensured. The back side silicon resin 2 and the gypsum 3 of the back side mold R are positioned by the solid silicon piece 22 and the recess 32. The surface side silicon resin 4 and the gypsum 5 of the surface side mold R are positioned by the solid silicon piece 42 and the recess 52 [see FIGS. 8A and 8B]. this

8th stage (Fig. 10)
A liquid mixture of surface soft urethane 6A is applied to the surface of the surface-side silicon resin 4 of the surface-side mold F so that it can be formed into a large number of protrusions 90a, 90a,. At this time, it is important that the gypsum 5 is reinforced. Since only the surface soft urethane 6A is not cured, it becomes an oily mixed liquid in order to mix an appropriate curing agent.

Stage 9 (Figure 11)
And the liquid mixture of back surface soft urethane 6B is apply | coated also to the surface of the back surface side silicon resin 2 of the back surface side type | mold R so that the back surface side of the said table coral original pattern 9 can be formed. Similarly, the gypsum 3 is also reinforced.

Stage 10 (Figure 12)
Apply to vacuum device 8. Specifically, in the vacuum operation, the surface side mold F having the surface soft urethane 6A (the surface side silicon resin 4 and the gypsum 5 are set in the vacuum device 8 (see FIG. 12). As shown in (B) to (D), the bubble k gradually increases in accordance with the vacuum force and can be released to the outside. As shown in FIG. 2, the bubbles k in the surface soft urethane 6A can be eliminated.

  In this way, the bubble k is removed and the outer shape is orderly. Furthermore, the back surface side mold F (the back surface side silicon resin 2 and the gypsum 3) having the back surface soft urethane 6B is also set in the vacuum device 8. And the bubble k in the back surface soft urethane 6B is also extracted. Further, the vacuum apparatus 8 often performs a deaeration process simultaneously on the front surface side mold F having the surface soft urethane 6A and the back surface side mold F having the back surface soft urethane 6B.

11th stage (Fig. 13)
In such a state, the front surface side mold F having the surface soft urethane 6A and the back surface side mold R having the back surface soft urethane 6B are overlapped (see FIGS. 13A and 13B). At this time, the convex portion 21 and the concave portion 41 should be matched. As a result, there is no mold misalignment and an accurate mold can be obtained. Finally, a mixed solution of internal soft urethane 6C is filled (see FIGS. 13C and 13D). Thus, the front surface soft urethane 6A, the back surface soft urethane 6B, and the internal soft urethane 6C are processed so as to be integrated without gaps. Natural drying is performed in this state.

Stage 12 (Figure 14)
After natural drying, the back surface side mold R is removed, and an internal table coral replica 99 is obtained. At this time, many thin plate pieces (not shown, but the same thickness as the thin plate piece 70 of FIG. 4) are formed between the protruding portions 90a, 90a,. The table coral replica 99 is manufactured by such a manufacturing method. In addition, coloring or the like is performed as necessary.

  In the above description, the table coral replica 99 is manufactured in the first to twelfth stages. First, the back surface side mold F is created, and then the front surface side mold R is manufactured. There is also another manufacturing method. This another manufacturing method is a manufacturing method in which the front surface side mold R is first created and then the back surface side mold F is manufactured. Further, when the projection 90a of the table coral prototype 90 is not deeply uneven, it may be manufactured without using the vacuum device 8. In addition, after the table coral replica 99 is manufactured, the thin plate piece is not peeled off and may be commercialized.

  Further, in the above description, when the surface side silicon resin 4 and the gypsum 5 of the surface side mold R are joined to each other, the solid silicon piece 42 and the concave portion 52 are matched and the mutual positioning is performed. Therefore, it can be manufactured as an accurate mold. In addition, a solid silicon piece 22 and a concave portion 22 are also provided for joining the back side silicon resin 2 and the gypsum 3 of the back side mold F.
