A method for manufacturing a sample product and a method for manufacturing a mold according to an embodiment of the present invention will be described below.
A method for producing a sample product is a method in which the wax is formed into a mold made of wax having an irregular shape that matches the surface shape of a sample product such as a real product (specifically, for example, doll-yaki) or a food product equivalent to the real product. A resin having a lower melting point is poured, the resin is cured, and after curing, the cured resin is released from the mold, and the cured resin is released from the mold.
The sample product is made to resemble the shape of the actual product. For example, in the case of food, it is a food sample that is a model of a dish displayed at a restaurant or in a store.

First, a manufacturing method of a mold for manufacturing a mold 10 (see FIG. 5) formed of wax (for example, melting point 132 ° C.) will be described with reference to FIGS.
FIG. 1 shows an actual product 1 (or a sample product such as food equivalent to the actual product) that is an object of manufacturing the sample product manufacturing method of the present invention. Real 1 [or sample products such as food equivalent to the real product (sample products are resins whose melting point is higher than that of wax, for example, silicon, ABS resin, polypropylene, polystyrene, polyethylene terephthalate, polyphenylene ether, polycarbonate, polyacetal, polybutylene. It is formed of terephthalate, polyphenylene sulfide, polyether ether ketone, liquid crystal polymer, fluororesin, etc.)] is, for example, doll ware.
The actual sample 1 [or sample product such as food equivalent to the actual product] is not limited to doll ware, but may be food such as castella, sponge cake, pancake, baked confectionery, etc. But it ’s okay.

First, as shown in FIG. 2, the wax 2 is put in the container 3, and the container 3 is heated to bring the wax 2 into a molten state. Further, as shown in FIG. 3, the wax 2 is applied over the entire surface of the actual object 1 [or a sample product such as food equivalent to the actual object] by the application means 4 (brush, brush, etc.).
This is particularly effective when the surface of the actual object 1 (or a sample product such as food equivalent to the actual object) is uneven, and by applying the wax 2 with the application means 4 (brush, brush, etc.), This is because the wax 2 is filled in the irregularities on the surface of the actual object 1 (or a sample product such as food equivalent to the actual object), so that a defect portion does not occur.

Next, as shown in FIG. 4, the molten wax 2 is poured into the mold 5 on which the actual object 1 (or a sample product such as food equivalent to the actual object) is placed (wax casting process).
When pouring the wax 2, it is desirable that bubbles in the poured wax 2 are defoamed using a vacuum defoaming machine (not shown).
After this wax casting step, the wax 2 is cured (wax curing step). The wax 2 is cured by natural cooling or the like. Desirably, forced cooling is performed by a refrigerator or the like.
After the wax curing step, the cured wax is released from the mold 5 (wax removal step). By this wax removing process, the mold 10 (see FIG. 5) can be manufactured by removing the cured wax from the mold 5. In addition, 10a shown in FIG. 5 is a space.

Next, a sample product manufacturing method for manufacturing the sample product 7 (see FIG. 9) using the mold 10 shown in FIG. 5 will be described with reference to FIGS.
The mold 10 described above is formed of wax having an uneven shape that matches the surface shape of the actual product (or a sample product such as food equivalent to the actual product).
As shown in FIG. 6, the mold 10 has a resin 20 having a melting point lower than that of the wax 2 (the resin 20 is a resin having a melting point lower than the melting point 132 ° C. of the wax, for example, silicon, ABS resin, polypropylene, polystyrene, polyethylene, for example. Terephthalate, polyphenylene ether, polycarbonate, polyacetal, polybutylene terephthalate, polyphenylene sulfide, polyetheretherketone, liquid crystal polymer, fluororesin, etc.) are allowed to flow (flowing step).
When the resin 20 is poured, it is desirable that bubbles in the poured resin 20 are removed using a vacuum defoaming machine (not shown). If the resin 20 is a foamed resin, the lid 7 ′ shown in FIGS. 6 and 7 is used to press in the arrow direction shown in FIG. 7 so that the lid 7 ′ does not move.

Next, after the resin curing step, the cured resin is separated from the mold 10 (detachment step). The resin 20 is cured by natural cooling or the like. Desirably, the resin 20 is forcibly cooled by a refrigerator or the like so that the resin 20 is hardly melted by the heat of curing.
Through this separation step, the cured resin 20 is separated from the mold 10 to produce the sample product 7 (see FIG. 8).
The sample part 7 can be manufactured by cutting away the unnecessary portion 8 of FIG.

    According to the sample product manufacturing method described above, the mold 6 having an uneven shape that matches the surface shape of the actual product (or a sample product such as food equivalent to the actual product) is a wax, and the resin 10 that flows through the mold 6 is a wax. In order to produce the sample product 7 by forming each with a material having a low melting point, when separating the cured resin 10 from the mold 6, separation between the cured resin 10 and the mold 6 formed of the wax 2 is good. The sample 6 can be manufactured for a long period of time with little damage to the mold 6, and the wax mold 6 is an inexpensive material and can be reused if melted even if the mold 6 breaks.
