Description

[Detailed explanation of the idea] The present invention relates to a wig mold making device.

Conventionally, when making a wig, a mold is made to obtain a base for flocking by inserting a vinyl or polyethylene sheet onto the head, pulling it downward, and then applying adhesive cotton or paper tape to the entire surface of the sheet and taking the mold. However, with this method, the inner surface of the mold becomes uneven, and the vinyl, polyethylene sheet, and adhesive tape shrink, making it impossible to obtain an accurate mold that matches the shape of the head.

In view of the above, the inventor of the present invention has conducted various studies and found that 1. For example, materials such as trans-type polyimrene have the property of softening and molding at low temperatures, that is, at temperatures that do not cause burns to the human body, and becoming hard when cooled to room temperature. I learned that it is possible to make molds using plastic thin sheets of synthetic resin.

However, since the material is a thin plate, mold-making operations such as heating and pressure-welding to the model require skill.To solve this problem, further research has revealed that the material can be stretched and held in a frame, making molding extremely easy. We have devised a wig molding device that can perform wig molding work.

The following describes an embodiment of the apparatus of the present invention shown in the drawings. Reference numeral 1 denotes a molding frame, for example, a wooden frame 2a.

Hinge 3 a t3 on one side edge of each 2b
b, which are connected to each other so that they can be opened and closed.

Then, one wooden frame 2a is attached to the four peripheries on the inner surface of both.
A large number of nail holes 4, 4... of the required depth are bored at intervals, and the other wooden frame 2b has needle tips 5, 5... corresponding to the nail holes 4, 4...・Protrudes and has a hinge of 3at.
The needle tips 5, 5, . . . are inserted into the nail holes 4, 4, .

Reference numeral 6 denotes a molding material, which is a transformer polyisoprene having a thickness of about 2 to 311 mm. This material is approximately the size of the molding frame 1, and the nail holes 4, 4, . . . Through-holes 7, 7, . . . are bored through which the corresponding needle tips 5° 5, . . . are fitted and stretched.

In the above embodiment, to form one head prototype, for example, a mold for making a partial wig scalp from the head, the molding frame 1 is folded into the state shown in FIG. 1, and the molding material 6 is placed between the wooden frames 2a and 2b. While the molding material is being held, place the surface of the molding material on top of the heater to heat it, and hold the molding frame 1 in both hands to the extent that it does not heat up even when it touches the scalp, and place the 6th surface of the molding material at the zenith of the head. Apply force downward little by little until the molding frame 1 has lowered to the level of the ear, stop applying the lower pressure, hang a band over the material, wait until the molding material 6 cools down, and then remove the mold. Finish taking.

The mold made in this way is a nearly round shape that closely matches the shape of the original head.

As shown in FIG. 3, the material 6 may have a bulge 8 formed in advance in a state that is almost similar to the original at the part where it contacts the original. If this is done, the pressing force will be less and the work will be easier. It can be easily done.

Additionally, a silicone mold release agent may be sprayed on the material surface as a mold release agent.

As mentioned above, the present invention is designed to improve the opening/closing ability of thin thermoplastic synthetic resin sheets, such as trans-type polyisoprene, which softens at low temperatures, can be molded, and hardens when cooled to room temperature.
The needle tip protruding from one frame surface is inserted into the frame and held.
By closing both frames, the needle tip can be inserted into the nail hole drilled in the other frame surface and expanded and held.
Subsequent mold making, i.e. heating of the mold material, suppression of the original shape,
Since the removal work can be performed smoothly, it is suitable for mold making, especially as a wig mold making device.
