  Hereinafter, the present invention will be specifically described with reference to an illustrated embodiment. FIG. 1 is a diagram for explaining a manufacturing process of a toy component material, and FIG. 2 is a perspective view of the toy component material manufactured in the manufacturing process of FIG.

  In FIG. 1, in the present embodiment, an example of a manufacturing process of a component material of a rotor blade for a helicopter toy is shown. First, as shown in FIG. 1 (a), as a foamed plastic material, for example, a glass fiber-containing adhesive tape is applied to one surface of a foamed polystyrene plate 11 having a thickness of about 2 mm and a predetermined size. 12 is pasted. This glass fiber-containing pressure-sensitive adhesive tape 12 was formed by sticking glass fibers to one surface of a polyester film together with a pressure-sensitive adhesive made of rubber, synthetic resin, synthetic rubber, or the like, and having a width of about 10 to 50 mm. Generally, it is used for packing heavy objects, binding parts, and the like. As the glass fiber-containing pressure-sensitive adhesive tape 12 used as the component material of the present embodiment, a tape having an arbitrary width can be used corresponding to the component to be manufactured. I was able to get it.

  Next, as shown in FIG.1 (b), the foamed polystyrene board 13 of the same thickness and area is stuck on the surface of the glass fiber containing adhesive tape 12 stuck on the foamed polystyrene board 11 with an adhesive agent. As this adhesive, any adhesive capable of adhering foamed polystyrene and polyester can be used. For example, an adhesive mainly composed of styrene butadiene rubber or acrylic rubber was able to obtain good results. That is, a material having a three-layer structure in which the glass fiber-containing adhesive tape 12 is interposed between the foamed polystyrene plates 11 and 13 is formed by the steps of FIGS.

  Next, as shown in FIG. 1C, the shape corresponding to the part to be molded is engraved. For example, a pair of metal molds 14 and 15 made of aluminum are used to form a three-layer structure material. After compression molding from both sides, the molds 14 and 15 are heated to about 120 ° C. and compression molded for about 5 seconds. Thus, the foamed polystyrene plates 11 and 13 are compressed and molded into a shape engraved in the molds 14 and 15 with the glass fiber-containing adhesive tape 12 sandwiched between the foamed polystyrene plates 11 and 13 from both sides. Subsequently, the molds 14 and 15 are cooled to about 30 ° C. in a compressed state, and the cooled state is maintained for about 30 seconds. By cooling the molds 14 and 15 in a compressed state, the molded shape can be maintained. In the present embodiment, the thickness of the foamed polystyrene plates 11 and 13 is, for example, compression-molded to about 1 mm, and the entire thickness is molded to about 2 mm as a component material.

  Next, as shown in FIG. 1 (d), unnecessary peripheral parts other than the part parts compression-molded by the process of FIG. 1 (c) are removed. As removal of such unnecessary peripheral portions, for example, a part can be punched out by a punching die. As a result, a thin-walled component material is formed by interposing the glass fiber-containing adhesive tape 12 between the foamed polystyrene plates 11 and 13 that have been compression-molded into the required component shape.

  Next, as shown in FIG. 1 (e), after the step of FIG. 1 (d), the surface of the compression-molded polystyrene plates 11 and 13 is glossed with a predetermined color, for example, as a plastic film. The toy component material 10 is manufactured by pasting the thin polyester films 16 and 17 having an adhesive mainly composed of styrene butadiene rubber or acrylic rubber. The polyester films 16 and 17 can not only provide a colored and glossy surface treatment, but can further improve the strength.

  FIG. 2 shows a rotor blade for a helicopter toy as a toy component material 10 manufactured by the above manufacturing process, and a glass fiber-containing adhesive tape 12 is interposed between the foamed polystyrene plates 11 and 13. It is compression-molded and has a structure in which polyester films 16 and 17 are attached to the surface.

  In the manufacturing method of the toy component material 10 having the above-described configuration, both surfaces of a material having a three-layer structure in which a glass fiber-attached adhesive tape 12 in which glass fibers are attached to the surface of a polyester film are interposed between foamed polystyrene plates 11 and 13. Then, after the molds 14 and 15 are compression-molded, the molds 14 and 15 are heated and then cooled in a compressed state to maintain the state, and unnecessary peripheral portions other than the compression-molded parts are removed. Then, thin polyester films 16 and 17 which are colored and glossy are pasted on the surface of the parts from which unnecessary portions are removed. The double-sided foamed polystyrene plates 11 and 13 having a three-layer structure with the glass fiber-containing adhesive tape 12 interposed between them can be easily compression-molded by the heated molds 14 and 15, and are compressed after the heat-compression molding. By maintaining the state and cooling the molds 14 and 15, it is possible to perform molding while maintaining the shape of the part. Moreover, since the glass fiber-attached adhesive tape 12 has glass fibers attached to one surface of the polyester film, it can eliminate the disadvantage of being easily damaged by the impact of the foamed polystyrene plates 11 and 13 and coloring the surface. By sticking the thin polyester films 16 and 17 having gloss, not only the surface treatment of the part surface is facilitated but also the strength can be improved. Further, in the toy component material 10 having the above-described configuration, a glass fiber-containing adhesive tape 12 in which a glass fiber is attached to the surface of a polyester film is interposed between the foamed polystyrene plates 11 and 13 and is compression-molded. Since it has a structure in which the polyester films 16 and 17 are attached to the surfaces of the foamed polystyrene plates 11 and 13, the strength of the foamed polystyrene plates 11 and 13 can be increased by the glass fiber-attached adhesive tape 12, and the polyester attached to the surface. The films 16 and 17 not only can further improve the strength, but also enable the colored glossy surface treatment required for the component material.

  FIG. 3 is a diagram for explaining a manufacturing process of a toy component material according to another embodiment of the present invention. 1 corresponding to those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the embodiment of FIG. 3, an example of the manufacturing process of the component material of the rotor blade for a helicopter toy similar to the above embodiment is shown. In this embodiment, as shown in FIG. 3 (a), one surface of the foamed polystyrene plate 11 is pasted with a thin polyester film 16 having a predetermined color and gloss, and the other surface is used. A glass fiber-containing adhesive tape 12 is affixed to the substrate. Next, as shown in FIG. 3 (b), a foamed polystyrene plate 13 in which a similar thin polyester film 17 having the same thickness and area is attached to the surface of the glass fiber-containing adhesive tape 12. That is, a material having a three-layer structure in which the glass fiber-containing adhesive tape 12 is interposed between the gun polystyrene plates 11 and 13 having the polyester films 16 and 17 attached to the surfaces, respectively, is formed. Next, as shown in FIG. 3 (c), a pair of molds 14 and 15 are used, and after the compression molding is performed from both sides of the material of the three-layer structure manufactured in the above process, the molds 14 and 15 are approximately After heating to about 120 ° C., the molds 14 and 15 are cooled to about 30 ° C. in a compressed state. Next, as shown in FIG. 3D, unnecessary peripheral parts other than the part parts compression-molded by the process of FIG. 3C are removed. Thus, the same toy component material 10 as in the above embodiment is manufactured.

  In the manufacturing method according to another embodiment having the above-described configuration, a three-layer structure in which a glass fiber-attached adhesive tape 12 is interposed by using gun polystyrene plates 11 and 13 in which polyester films 16 and 17 are previously attached to one surface is used. By forming the material and compression molding with the dies 14 and 15, the step of FIG. 1 (e) can be omitted. The toy component material 10 manufactured by this manufacturing method can eliminate the drawbacks of being easily damaged by impact and the like as described above, and the surface of the component is made of thin polyester films 16 and 17 which are colored and glossy on the surface. In addition to facilitating the surface treatment, the strength can be further improved.

  In each of the above embodiments, the rotor blade for a helicopter toy has been described as an example, but as other toy parts, not only can it be applied to a fuselage, wing, propeller, etc. constituting a flying toy, but also a hovercraft toy fuselage, ship It can be used for toy parts such as toy hulls and decks that require strength and light weight. Moreover, although it is set as the three-layer structure which interposed the glass fiber containing adhesive tape 12 between the foaming polystyrene plates 11 and 13, the foaming polystyrene plates 11 and 13 may be other foaming plastic plates which can be easily heated and compressed. Well, instead of the glass fiber-containing adhesive tape 12, for example, a fiber-containing adhesive tape containing carbon fibers can be used.

  It can be used for a toy component material that can be easily molded and is lightweight and difficult to break as a component material such as a flying toy, a hovercraft toy, or a ship toy.
