Description

[Technical field]

[0001] The present invention relates to shaped objects and methods for making shaped objects. [Background technology]

[0002] Traditionally, the facial features of a figurine (eyes, eyelashes, etc.) are very important in determining the value of the figurine as well as influencing the figurine's expression. For example, Patent Document 1 describes a method for manufacturing doll eyes, in which an elastic silicone resin or other contacting body is pressed against a coating film that imitates the iris of an eyeball by printing, and the attached coating film is transferred to a spherical surface that imitates the eyeball. In this way, the pattern of the iris formed by printing can be formed on the surface of the eyeball by transferring the coating film, making it possible to express the iris with high precision. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-24382 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when trying to represent the eyes by printing, there is a risk that they will be misaligned with respect to the eyeball surface. In products such as the face of a figurine, where even the slightest misalignment of the facial representation member creates a sense of incongruity, misaligned eyeballs can diminish the value of the product.

[0005] In the case of plastic model figures that require the user to carry out some of the assembly, the eyes and face of the figure have traditionally been expressed with stickers. However, the process of applying the stickers by the user takes time, and the stickers can sometimes be misaligned. It also requires skill to apply the stickers in a way that does not look strange to the user, making it difficult to create a satisfactory finished product.

[0006] The present invention provides an object that can easily create a representation of an eye with high accuracy. [Means for solving the problem]

[0007] According to one aspect of the present invention, for example, there is provided an object in which an eye part is assembled to a facial part to form a face, the eye part comprising an eye base part and an eye expression part which covers at least a portion of the eye base part and is molded integrally with the eye base part, and the facial part is formed with a hole through which a portion of the eye part is exposed when the eye part is assembled. Effect of the Invention

[0008] According to the present invention, it is possible to provide a figure that can easily form an expression of an eye with high accuracy. [Brief description of the drawings]

[Diagram 3] (A) is a perspective view of the primary molded part, (B) is a secondary molded part, and (C) is a tertiary molded part of the eye part. [Figure 4] (A) is a perspective view of the front of the facial part, and (B) is a perspective view of the back. [Diagram 5] (A) is a perspective view of the primary molded part, (B) is a secondary molded part, and (C) is a tertiary molded part of the facial expression parts. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an exemplary embodiment of the present invention will be described with reference to the drawings. In each drawing, the same reference numerals indicate the same elements. In each drawing, the up, down, left and right directions relative to the paper surface will be used in the description in the text as the up, down, left and right directions of the device in this embodiment. In the embodiment described below, the present invention will be exemplified by resin materials of different colors as molding materials, but is not limited to this, and can be applied to molding materials of different materials (thermoplastic resins such as polystyrene, polyethylene, ABS, thermosetting resins, metals, etc.), resins of different transparencies, etc.

[0011] Fig. 1 shows a figurine A according to an embodiment of the present invention. The figurine A described below is exemplified as a figurine resembling a human face, but is not limited thereto, and may be any figurine that has eyes, such as animals, insects, dinosaurs, fish, or other living creatures, or characters that have parts equivalent to eyes.

[0012] The face of figure A is formed by assembling eye parts 10 to facial parts 20. Fig. 1(A) shows the front side of figure A, and Fig. 1(B) shows the back side of figure A. In this embodiment, the back side of figure A is covered by a hair part (not shown) and is not exposed to the outside after the figure is completed. Fig. 2 shows an exploded perspective view of eye part 10 and facial part 20. Eye part 10 is assembled from the back side of facial part 20, and a part of eye part 10 constituting eye 10a is exposed from a hole 20a formed in facial part 20.

[0013] <Eye parts 10> In this embodiment, the eye part 10 is formed by insert molding and multi-color molding using four colors of resin. The eye part 10 includes an eye basic part 11 and a plurality of eye expression parts 12, 13, and 14 that are integrally molded by covering at least a part of the eye basic part 11. Figure 3 shows molded products at each stage in the molding process until the eye part 10 is formed.

[0014] Fig. 3(A) shows an eye basic part 11 as a primary molded part E1. Fig. 3(B) shows a secondary molded part E2 in which the eye basic part 11 and a first eye representing part 12 made of one different resin material are molded into an integrated part by insert molding using the eye basic part 11 (insert molding with the eye basic part 11 as an insert part). Fig. 3(C) shows a tertiary molded part E3 in which the secondary molded part E2 is simultaneously multi-color molded using a second eye representing part 13 and a third eye representing part 14 made of two different resin materials. In this embodiment, the tertiary molded part E3 is the final molded part of the eye part 10.

[0015] In each figure, three perspective views of each molded product are shown in different directions, with the top one being a perspective view of the molded product seen from approximately the front, the middle one being a perspective view seen from diagonally above, and the bottom one being a perspective view seen from below. Note that the front refers to the front of the face of figure A, the top refers to the top of figure A (e.g., the head), and the bottom refers to the bottom of figure A (e.g., the chin part of the face).

[0016] 3(A) shows a primary molded product E1 including an eye basic part 11 of the eye part 10. In this embodiment, the eye basic part 11 is molded from a white resin material and constitutes the white part of the figure's eye 10a. The part that will be exposed to the surface in the final molded product is indicated as a first exposed part 11a.

[0017] 3(B) shows a secondary molded product E2 in which the eye basic part 11 and the first eye representation part 12 made of a type of resin material different from that of the eye basic part 11 are molded into one integral part. The resin material for molding the first eye representation part 12 can be, for example, a black resin material, and represents the pupil of the eye 10a, etc.

[0018] When molding the secondary molded product E2 shown in Fig. 3(B), after molding the primary molded product E1, the primary molded product E1 is transferred to a mold different from the mold in which the primary molded product E1 was molded or to another part of the same mold, and the primary molded product E1 is molded so that the first eye expression part 12 is covered with the black resin material. Therefore, the secondary molded product E2, which is an integral molded product of the primary molded product E1 and the first eye expression part 12, is formed by insert molding (insert molding with the primary molded product E1 as an insert part) using the primary molded product E1 (eye base part 11). The part exposed to the surface in the final molded product is indicated as the second exposed part 12a.

[0019] 3(C) shows a tertiary molded product E3 (final molded product) formed by integrally molding the secondary molded product E2 with a second eye representation part 13 and a third eye representation part 14 made of two different types of resin from the eye base part 11. The resin material for molding the second eye representation part 13 can be, for example, a gray resin material, which represents the shadow of the white of the eye caused by the eyelid of the figure. The resin material for molding the third eye representation part 14 can be, for example, a purple resin material, which represents the iris of the eye 10a of the figure.

[0020] When molding the tertiary molded product E3 shown in FIG. 3(C), after molding the secondary molded product E2, the secondary molded product E2 is transferred to a mold different from the mold in which the secondary molded product E2 was molded or to another part of the same mold, and the secondary molded product E2 is molded so that the second eye expression part 13 is covered with the above-mentioned gray resin material and the third eye expression part 14 is covered with the above-mentioned purple resin material. When molding the second eye expression part 13 and the third eye expression part 14, if the resins of the parts do not mix due to the arrangement of the parts, etc., each resin material can be simultaneously injection molded using a multi-color molding technique. Therefore, the tertiary molded product E3, which is an integral molded product of the secondary molded product E2, the second eye expression part 13, and the third eye expression part 14, is formed by insert molding and multi-color molding using the secondary molded product E2. The parts exposed to the surface in the final molded product are indicated by the third exposed part 13a and the fourth exposed part 14a.

[0021] As described above, the eye 10a of the eye part 10 is formed by repeating insert molding using multiple types of resin. Therefore, it is possible to easily form the expression of the eye, which has conventionally been provided by printing or stickers, with high accuracy. Furthermore, even in the case where the user is required to carry out part of the assembly, as in the case of a plastic model, the process of applying stickers by the user to express the eye can be eliminated, and a satisfactory finished product can be created in a form that does not feel unnatural to the user, even without high skills such as applying stickers or painting.

[0022] <Facial Parts 20> FIG. 4 shows a perspective view of the facial part 20. FIG. 4(A) shows the front side of the facial part 20, and FIG. 4(B) shows the back side of the facial part 20. The facial part 20 includes an expression part 21 and a skin part 25 that covers at least a part of the expression part 21 and is molded integrally with the expression part 21. The facial part 20 is also formed with a hole 20a that exposes a part of the eye part 10 (eye 10a). A part of the expression part 21 is exposed from the skin part 25 to represent at least either eyelashes or eyebrows, and may also represent the shadow of an eyelid. The skin part 25 is molded, for example, from a flesh-colored resin material, and forms the skin part of the figure's face.

[0023] In this embodiment, the facial expression part 21 is arranged at least on a part of the periphery of the hole 20a, and includes an eyelash part 22a representing eyelashes, an eyebrow part 23a arranged away from the eyelash part, and an eyelid part 24a representing the shadow of the eyelid between the eyelash part 22a and the eyebrow part 23a. The eyelash part 22a, the eyebrow part 23a, and the eyelid part 24a are molded from different resin materials.

[0024] As shown in Fig. 5, the facial expression part 21 is formed by insert molding using three-color resin materials. The facial expression part 21 includes a primary facial expression part 22, and a secondary facial expression part 23 and a tertiary facial expression part 24 which are molded integrally with the primary facial expression part 22 by covering at least a part of the primary facial expression part 22. Fig. 5 shows the molded product at each stage in the molding process until the facial expression part 21 is formed.

[0025] Fig. 5(A) shows the primary facial expression part 22 as the primary molded product F1. Fig. 5(B) shows a secondary molded product F2 in which the primary facial expression part 22 and the secondary facial expression part 23 made of one different resin material are molded into an integrated product by insert molding using the primary facial expression part 22 (insert molding with the primary facial expression part 22 as an insert part). Fig. 5(C) shows a tertiary molded product F3 in which the secondary molded product F2 and the tertiary facial expression part 24 made of one different resin material are molded into an integrated product by insert molding using the secondary molded product F2 (insert molding with the secondary molded product F2 as an insert part). In this embodiment, the tertiary molded product F3 is the final molded product of the facial expression part 21.

[0026] In each figure, two perspective views of each molded product are shown in different directions, one above the other, with the upper one being a perspective view of the molded product seen from approximately the front (front side) and the lower one being a perspective view of the molded product seen from the back. The front view refers to the front of the face of the shaped object A.

[0027] 5(A) shows a primary molded product F1 including a primary facial expression part 22 of the facial expression part 21. In this embodiment, the primary facial expression part 22 is molded from a black resin material and includes a portion representing eyelashes arranged around the periphery of the figure's eye 10a. The portion exposed to the surface of the skin part 25 in the final molded product is indicated as eyelash portion 22a.

[0028] The eyelash portion 22a is formed by rising from the bottom surface of the primary facial expression part 22, and the part exposed to the surface may be formed as a thin linear part or an angular part formed with a very small R. Such eyelash portion 22a may be broken or chipped and damaged in the mold when the primary molded product F1 is removed from the mold or when it is embedded in the next mold during insert molding. In order to prevent such damage, the joint between the eyelash portion 22 and the bottom surface of the primary facial expression part 22 may be reinforced by forming a padded part or providing a tapered surface from the bottom surface of the primary facial expression part 22 to the eyelash portion 22.

[0029] The primary facial expression part 22 also has holes 22b, 22c and a cutout 22d. The holes 22b, 22c and the cutout 22d are provided to increase the contact area with the die on the core side and pull the primary molded product F1 toward the core side so that the primary molded product F1 is not taken to the die on the opposite side to the core side (the side with the ejector pin) when the die is opened after injection molding. The holes 22b, 22c and the cutout 22d are filled with the secondary facial expression part 23 and the tertiary facial expression part 24, which will be described later.

[0030] 5(B) shows a secondary molded product F2, which is an integral molded product of the primary molded product F1 and the secondary facial expression part 23 made of a type of resin material different from the primary facial expression part 22. The resin material for molding the secondary facial expression part 23 can be, for example, a brown resin material, which represents the eyebrows of the figure.

[0031] When forming the secondary molded product F2 shown in Fig. 5(B), after forming the primary molded product F1 (pre-stage molding), the primary molded product F1 is transferred to a mold different from the mold in which the primary molded product F1 was formed or to another part of the same mold, and the secondary facial expression part 23 is molded so as to cover the primary molded product F1 with the brown resin material. Therefore, the secondary molded product F2, which is an integrated molded product of the primary molded product F1 and the secondary facial expression part 23, is formed by insert molding using the primary molded product F1 (insert molding with the primary molded product F1 as an insert part). The part exposed to the surface of the skin part 25 in the final molded product is indicated as the eyebrow part 23a.

[0032] The eyebrow portion 23a may have a padded portion or a tapered surface formed at its base, similar to the eyelash portion 22a. A part 23b of the secondary facial expression part is embedded in the hole 22b of the primary facial expression part 22.

[0033] 5(C) shows a tertiary molded product F3 (final molded product) which is an integral molded product of the secondary molded product F2 and the tertiary facial expression part 24 made of one type of resin material different from the secondary facial expression part 23. The resin material for molding the tertiary facial expression part 24 can be, for example, a light brown resin material, which expresses the shadow of the skin formed by the eyelids of the figure.

[0034] When forming the tertiary molded product F3 shown in Fig. 5(C), after forming the secondary molded product F2, the secondary molded product F2 is transferred to a mold different from the mold in which the secondary molded product F2 was formed or to another part of the same mold, and the secondary molded product F2 is molded so that the tertiary facial expression part 24 is covered with the light brown resin material. Therefore, the tertiary molded product F3, in which the secondary molded product F2 and the tertiary facial expression part 24 are molded as an integrated molded product, is formed by insert molding using the secondary molded product F2 (insert molding with the secondary molded product F2 as an insert part). In this way, the facial expression part 21 is formed. The part exposed to the surface from the skin part 25 in the final molded product is indicated as the eyelid part 24a.

[0035] The eyelid portion 24a may have a padded portion or a tapered surface formed at its base, similar to the eyelash portion 22a. A part 24c of the tertiary facial expression part is embedded in the hole 22c and the notch 22d of the primary facial expression part 22.

[0036] Furthermore, by insert molding (insert molding with the tertiary molded product F3 as an insert part) using the facial expression part 21 (tertiary molded product F3), the facial expression part 20 is formed by molding, for example, the skin part 25 with a flesh-colored resin material so as to cover the facial expression part 21. As described above, the facial expression part 20 is formed by repeatedly using the primary molded product F1 of the facial expression part 21 (with the primary molded product F1 as an insert part) to perform insert molding using multiple types of resins, so that the facial expression part 21 and the skin part 25 are molded as an integrated molded product.

[0037] The eye part 10 and the facial part 20 may be molded to have different glosses. For example, the eye part 10 may be molded from a highly transparent resin material such as polystyrene resin, and the facial part 20 may be molded from a resin that is made by compounding rubber or the like with polystyrene resin to reduce gloss and provide the texture of skin.

[0038] As described above, in this embodiment, it is possible to easily express the eyes with high accuracy. Furthermore, even in products such as the face of a figurine, where even the slightest misalignment of the facial expression members creates a sense of incongruity, the positions of the facial expression members can be accurately positioned. Therefore, in the case of a plastic model figurine, it is possible to produce a finished product that is satisfactory to the user in a manner that does not create a sense of incongruity.
