Description of the Related Art Conventionally, as a method for producing a wig base, a synthetic resin solution prepared by dissolving a synthetic resin or a thermoplastic resin in an organic solvent or the like is applied to a male mold and then dried to evaporate the organic solvent or the like. There is known a so-called casting method in which the steps of coating and drying are repeated to form a wig base having a desired thickness.

要求される。In the casting method in which the above synthetic resin solution is applied to the male-head type, air is easily entrained during the application or drying of the synthetic resin solution, and air bubbles are easily generated in the wig base. This causes a decrease in the strength of the wig base after molding, and there is a problem that the appearance is impaired by the inclusion of air bubbles. Furthermore, when using a male-head type, there are irregularities and slopes on the surface,
The applied synthetic resin solution was likely to be accumulated in the concave portions to increase the film thickness, and the synthetic resin solution was likely to flow down in the convex portions and the inclined portions to decrease the film thickness. And in the above casting method, in order to obtain a desired film thickness by one-time coating, it is possible to increase the concentration of the resin component of the synthetic resin solution or increase the coating amount per one time.
It is difficult to cause air bubbles to be mixed in the wig base or to cause variations in film thickness.In actual manufacturing of the wig base, lower the resin concentration of the synthetic resin solution, and apply and dry until the desired film thickness is achieved. However, there is a problem in that it takes a long time for the work. Further, in the case of the manufacturing method in which the synthetic resin solution is applied, the viscosity of the synthetic resin solution is likely to cause a difference in the film thickness of the wig base, and therefore the viscosity of the synthetic resin solution needs to be adjusted and skill is required.

題もあった。On the other hand, in the blow molding method and the vacuum molding method, a female mold is generally used as a molding mold, whereas a male mold is generally used as a molding mold in general production of a wig base. Furthermore, since the male and female mold has irregularities and inclinations, which must be reproduced faithfully and have a uniform film thickness, conventional blow molding and vacuum molding methods cannot be used as they are for the production of wig bases. Have difficulty. Moreover, when the wig base is worn, the molded product itself needs to have a predetermined elasticity, for example, it is formed from a sheet-like material having a thickness of about 1 mm or less.
As shown in FIG. 12, when a sheet-like material S having a fixed periphery is heated by a heating device K, the sheet-like material S is bent by its own weight, and compressed air is sent to expand the sheet-shaped material S before it is preformed, and The bent sheet S has a problem that uneven heating occurs because the gap between the bent sheet S and the heating device K is partially different.

ート21をかつらベースとして加工してもよい。Next, the manufacturing method by the molding apparatus 1 using the sheet material 10 will be described. First, as shown in FIG. 2, the molding die is placed on the lift table 9 which is elevated to the position of the upper opening 3 by the air cylinder 12. Place 20 and air cylinder 12
Is operated to lower the molding die 20 as shown in FIG. Next, on the pedestal 4 of the molding apparatus 1, the sheet material 10 is arranged with the sheet 21 on the upper side, and when the sheet material 10 is heated, in order to prevent the excessive portion outside the sheet 21 from being softened by heating, A holding frame portion 5A having an opening having the same shape as the upper opening 3
The sheet material 10 is sandwiched and fixed by covering the sheet clamp 5 provided with, and the heater 8 is moved to an upper position of the sheet material 10 and heated. When the sheet material 10 is heated and begins to soften, as it is, the sheet material 10 is bent as shown in FIG. 12 of the prior art. However, in order to suppress the bending, when the sheet material 10 is heated, the compressor is compressed. The compressed air is gradually sent to the internal space 11 by operating 19 to hold the softened sheet material 10 by the air pressure in the internal space 11 so as not to shift from the position of the upper opening 3 as shown in FIG. After the sheet material 10 is heated and softened, the heating heater 8 is moved onto the auxiliary table 6, and as shown in FIG. 5, pre-forming for inflating the sheet material 10 by sending higher pressure compressed air to the internal space 11. I do. As for the extent to which the compressed air is supplied to inflate the sheet material 10, it is preferable that the bulge height H of the sheet material 10 is equal to or higher than the height of the molding die 20, as shown in FIG. Also, in the heating process and the inflating process,
Compressed air is not only at room temperature
50 ~ 80 ° C to prevent 10 from cooling and hardening
Compressed air that has been heated to some extent may be sent. Next, the air cylinder 12 is operated to raise the elevating table 9 so that the molding die 20 is pushed up and inserted into the bulged sheet material 10, and the vacuum pump 16 sucks the space between the sheet material 10 and the molding die 20. The air is evacuated to bring the sheet material 10 into close contact with the mold 20. When the molding die 20 is pushed up, the air in the internal space 11 is compressed as the lift 9 rises, and the sheet material 10 is inflated uniformly, and the air serves as a cushion, and when the molding die 20 is pushed up, the sheet material 10 is pushed up. The mold 20 is inserted into the bulged inside of the sheet material 10 without partially contacting the sheet material 10. The air between the sheet material 10 and the molding die 20 is sucked through the gap between the upper surface of the elevating table 9 and the lower surface of the molding die 20. For example, if the molding die 20 is a gypsum mold formed by pouring gypsum,
At the time of this molding, the plaster shrinks to naturally form irregularities (not shown) on the lower surface, so that air can be sucked through the gaps due to the irregularities. Then, the sheet material 10 is brought into close contact with the molding die 20 by evacuation and cooled to about room temperature, and then the sheet material 10
After releasing 10 and peeling off the sheets 21 and 22, or cooling to about room temperature, the sheet is kept in close contact with the forming die 20.
The sheet 21 may be peeled from the sheet 22. Further, in the case of further matting the surface of the upper surface of the sheet material 10, after adding a matting agent to a synthetic resin solution prepared by dissolving a synthetic resin or a thermoplastic resin in an appropriate organic solvent, after applying to the surface. ,
After drying to evaporate the organic solvent, the sheet material 10 is finally released from the molding die 20, the sheets 21 and 22 are separated from each other, and the sheet 21 is cut into a base shape of a wig and other wigs such as flocked hair are cut. Perform the manufacturing process. In order to further improve the strength of the wig base, as shown in FIGS. 8 and 9,
After molding a mesh net 24 made of synthetic resin, for example, a nylon net, it is stopped along the sheet 21 before release, and a synthetic resin solution in which a synthetic resin or a thermoplastic resin is appropriately dissolved in an organic solvent is applied and dried. Then, the organic solvent is dried to form a synthetic resin film 25 on the sheet 21, and finally the sheet material 10 is released from the molding die 20, and the sheets 21 and 22 are further separated.
The sheets 21 are separated from each other, and the sheet 21 is cut into a base shape of a wig, and another wig manufacturing process such as flocking is performed. As the resin of the synthetic resin solution applied in these cases, thermoplastic polyurethane is preferable, and as the organic solvent, DMF (dimethylformald) and MEK (methyl ethyl ketone) are preferable. Of course, the above-described matting process or the process of adhering the mesh net 24 is not performed, and after molding, from the molding die 20 to the sheet material.
It is also possible to release 10 and release the sheets 21 and 22 from each other, and process the sheet 21 as a wig base.
