Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a body member, a head member, and a head member made of synthetic resin.
The present invention relates to a method of manufacturing doll members such as leg members.

(Prior art and its problems) In general, doll body members, head members, arm members, leg members, and other members are made of soft synthetic resin such as soft vinyl chloride in a single layer by slush molding, rotation molding, etc. Molded. however,
Doll members made using conventional manufacturing methods have the following drawbacks.

For example, the arm member is integrally formed from the arm near the shoulder to the fingertip, but the shape of the fingertip is more complex than the arm, so in normal molding,
As shown in FIG. 3, the inside of the fingertip portion 10a is filled with synthetic resin. Therefore, even if appropriate flexibility is obtained in the arm portion 10b, the fingertip portion 10a
becomes hard. On the other hand, the fingertip portion 10
In order to make the flesh of arm 10b flexible, a softer synthetic resin may be used or the flesh may be made thinner, but the flesh of arm 10b may become extremely soft or thin. Because of this, the inside can be seen through, and it is too soft, causing problems with shape retention.When filling the inside with core material for reinforcement, the uneven parts of the core material push up the soft meat and come out. The appearance becomes rugged and the product quality is impaired.

(Object of the invention) The present invention was made in view of the above circumstances, and
In particular, the object of the present invention is to propose a method for manufacturing a synthetic resin doll member that is as flexible as human skin, has a good feel, and is resistant to unnatural deformation.

(Means for achieving the object) In order to achieve the above object, the method for manufacturing a synthetic resin doll member according to the present invention is characterized by comprising the following steps.

(b) Putting soft vinyl chloride into the molding concave surface of the molding die and layering an outer skin layer inside the molding concave surface by rotating the molding mold; (b) Placing soft vinyl chloride together with the soft vinyl chloride in the molding die (c) forming an inner skin layer inside the outer skin layer by mixing a foaming agent and rotating the mold while foaming the foaming agent; Removal from the mold and filling the inside with core material (functions and effects of the invention) According to the above configuration, the doll member includes an outer skin layer that feels smooth like human skin and an inner skin layer that is low-density and flexible. can be obtained.

Since the outer skin layer made of vinyl chloride is layered and then the inner skin layer made of foamed resin is layered, each layer forms a distinct layer. Therefore, the foamed, unnatural-looking inner skin layer is not exposed on the smooth outer skin layer like human skin, and the yield of the product is high.

In addition, the core material is filled within the endothelial layer and is independent of the endothelial layer, so when a doll member is pressed from the outside, the external pressure is applied only to the part that is directly pressed against the core material. , the resistance is relatively small and a natural deformation state can be obtained. On the other hand,
When the core material and the inner skin layer/outer skin layer are integrated, external pressure from the outside spreads to the core material through the integrated portion, so the core material has a large resistance to deformation and is relatively difficult to deform. Therefore, according to the present invention, it is possible to obtain a doll member that is entirely flexible and highly realistic, close to human skin.

(Example) Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral A denotes an arm member of a doll according to the present invention, and this arm member A has an inner skin layer 2 made of a foamed synthetic resin material inside an outer skin layer 1 made of a soft synthetic resin such as soft vinyl chloride resin. The arm member main body 3 has a double structure and is filled with a core material 4 such as cotton or urethane resin material.

The arm member main body 3 can be molded by the steps shown in FIGS. 2a to 2d.

First, soft vinyl chloride is placed as a molding material into the molding concave surface 5a of the molding die 5 as shown in FIGS. The mold 5 is rotated and the molding material is adhered to the inside of the molding concave surface to form a thin outer skin layer 1.

Next, by further mixing a foaming material together with soft vinyl chloride into the mold 5 in which the outer skin layer 1 has been layered and rotating it while foaming, as shown in FIG. Furthermore, an endothelial layer 2 is formed. Thereafter, the arm member main body 3 can be molded by pulling this molded product 3 out of the mold 5 as shown in FIG. 4(d).

Furthermore, the arm member A shown in FIG. 1 can be obtained by filling the arm member main body 3 with a core material 4 such as cotton or urethane resin material.

Note that the doll member having the above-mentioned structure is not necessarily limited to the rotation molding method, and may be formed by other molding methods such as the slush molding method.

According to the above-described manufacturing method, it is possible to obtain a doll member including an outer skin layer 1 that has a smooth feel like human skin and an inner skin layer 2 that is low in density and flexible.

Since the inner skin layer made of foamed resin is formed after the outer skin layer 1 made of vinyl chloride is formed, each layer forms a distinct layer. Therefore, the foamed, unnatural-looking inner skin layer 2 is not exposed on the smooth outer skin layer 1 like human skin, and the yield of the product is high. On the other hand, there are similar manufacturing methods, such as those shown in Japanese Patent Application Laid-Open No. 49-83538 and Japanese Utility Model Application No. 54-96391, but these techniques are based on synthetic resin materials and foam materials. This product is obtained by placing a mixture of the above ingredients into a mold and using centrifugal force and temperature control to prevent the surface from foaming.It is technically extremely difficult to completely prevent the surface from foaming. be.

In addition, since the core material 4 is filled in the inner skin layer 2 and exists independently from the inner skin layer 2, when the doll member is pushed from the outside, the external pressure is not directly applied to the core material 4. Since the pressure is applied only to the pressed part, the resistance is relatively small and a natural deformation state can be obtained. On the other hand, if the core material 4 and the inner skin layer 2 and the outer skin layer 1 are integrated, external pressure from the outside will spread to the core material through the integrated part, so the core material will have a large resistance to deformation, so it will be relatively deformed. It's hard to do. Therefore, according to the present invention, it is possible to obtain a doll member that is entirely flexible and highly realistic, close to human skin.

Note that the method for manufacturing doll members is not limited to the manufacture of doll arm members, and may also be applied to doll arm members, leg members, arm members, etc., of dolls, for example.
