Description

  TECHNICAL FIELD The present invention relates to an article for forming a concealing body, a molded article using the same, and a molding method, and more specifically, an article for forming a concealing body suitable for producing a molded article having a good surface appearance and an excellent appearance using the same. And a molding method thereof.

  Generally, when the molded product has holes or when the molded product has two or more gates, the molded material is separated during the process of supplying the molten molded material to the cavity in the molding die. Since a flow that flows and then merges occurs, a weld line is formed at the merged portion. This weld line occurs because the tip of the melted molding material flowing in the cavity increases in viscosity as the temperature decreases, and the tips do not fuse and integrate well when coalescing after splitting. . The occurrence of such a weld line has been the main cause of impairing the design of the product appearance.

  Therefore, in order not to impair the design even if appearance defects due to the weld line occur, from Patent Document 1 described later, injection molding is performed in advance on the mold surface where the weld line occurs in the injection mold. After mounting the thermoplastic film or sheet to be welded with the resin to be used so as to cover the surface of the mold, the molten resin is injected and injected into the mold to weld the film or sheet to the injected resin. A method for eliminating the weld line and the molded product is known.

  The technology of Patent Document 1 prevents the occurrence of the weld line itself by the pre-mounted thermoplastic film or sheet acting as a heat insulating layer and reaching the junction without the molten resin tip being cooled, Examples of the constituent material of the plastic film or sheet include transparent or opaque plastics. Further, transparent plastics are preferable in terms of improving appearance quality in addition to improving weld strength. Further, from Patent Document 2 described later, a weld with a fine unevenness formed on the printed surface by printing non-aqueous printing ink on the surface of the molded product after injection molding by a screen printing method or the like. A method for making the line invisible from the front side of the molded product is known.

  However, in the technique of Patent Document 1 in which injection molding is performed in the presence of a thermoplastic film or sheet, the thermoplastic film or sheet serves as a heat insulating layer between the cavity and the molten resin. Cooling cannot be completely suppressed, and if the heat insulation effect at the flow front cannot be sufficiently obtained, there is a problem that a weld line is generated, causing a poor appearance, and what is a weld line such as a flow mark? There is a problem that it is not effective for poor appearance caused by another cause.

Note that the plastics described in lines 3 to 40 in the third column of Patent Document 1 are plastic films or sheets that are mounted so as to cover the mold surface, even if they are opaque. Since it is extremely thin and has poor light shielding properties, it is practically impossible to hide the weld line. On the other hand, in the technique of Patent Document 2 that covers the weld line with the colored ink, a printing process for printing an ink layer on the surface of the molded product after injection molding is performed, and thus another process is required in addition to the molding process. Further, depending on the type of solvent contained in the non-aqueous ink, the molding material may be eroded and deteriorated. Therefore, there is a problem that the non-aqueous ink that can be used depending on the molding material is limited and the application range is limited.
Japanese Patent Publication No. 4-52766 (Claim 1, lines 12 to 16 in the third column, lines 32 to 40 in the third column) JP 58-42438 A (Claim 1)

The molding method of the present invention includes the step of installing the concealing body forming film 1 of FIGS. 4 and 5 corresponding to the first step, the mold closing step of FIG. 6, and the molding material supply of FIG. 7 corresponding to the second step. 8, the mold opening process of FIG. 8 corresponding to the third process, and the trapezoidal molding in which the carrier film layer 2 is peeled off from the masking body 3 and the surface is masked by the masking body 3 although illustration is omitted. It consists of a fourth step for obtaining the product 4, and these steps are sequentially repeated to continuously form the trapezoidal molded product 4 shown in FIG. 2 and FIG. These steps will be described in order.

  4 and FIG. 5, in the installation process of the concealing body forming film 1, the concealing body forming film 1 is the base of the cavity surface 511 of the first mold part 51 and the cavity surface 521 of the second mold part 52. On the cavity surface 511 side corresponding to the surface to be the design surface of the shaped molded product 4, the carrier film layer 2 is installed and fixed in the first mold part 51 so that the outer surface of the carrier film layer 2 is in contact with the cavity surface 511. .

  At that time, the positioning of the carrier film layer 2 is accurately performed by a photoelectric sensor or the like, and the relative positioning of the masking body forming film 1 and the cavity surface 511 is performed. This positioning may be performed by making a hole in the carrier film layer 2 in advance and fitting this hole with a pin (not shown) provided in advance in the first mold part 51. In the trapezoidal molded article 4, the concealer forming film 1 is inserted and fixed only on the cavity surface 511 side of the first mold portion 51 corresponding to the surface 45 (see FIG. 3). When the design surface of the shaped molded product 4 is the back surface 44, the concealment body forming film 1 is inserted and fixed to the cavity surface 521 side of the second mold portion 52 corresponding thereto. Alternatively, if both surfaces 44 and 45 of the trapezoidal molded product 4 are designed surfaces, the concealer-forming film 1 is formed on the cavity surface 511 side of the first mold part 51 and the second mold part 52. It arrange | positions at the cavity surface 521 side, respectively. In the example of FIGS. 4 and 5, only the surface of the molded product on the cavity surface 511 side is a design surface. Therefore, the concealer-forming film 1 is inserted and fixed only in the first mold portion 51, and the trapezoidal molded product 4. Even if a weld line or a flow mark is generated on the back surface 44, the appearance is not impaired. Therefore, the hidden film 1 is not installed on the cavity surface 521 on the second mold portion 52 side.

  Next, after the carrier film layer 2 is positioned, the carrier film layer 2 is in contact with the cavity surface 511 corresponding to the design surface of the trapezoidal molded product 4, so The carrier film layer 2 is brought into close contact with the cavity surface 511, for example, by vacuum suction or by pressing the cover-forming film 1 against the cavity surface 511 by a method such as air pressurization. FIG. 5 shows a state in which the masking body forming film 1 is in close contact with the cavity surface 511.

  In the mold closing process of FIG. 6, the mold is closed until the first mold part 51 and the second mold part 52 abut each other. A cavity 53 is formed between the cavity surfaces 511 and 521 by closing the mold. In the molding material supply step of FIG. 7, a material to be molded, for example, a melt of an organic polymer, is supplied into the cavity 53 from the resin supply hole 522 provided in the second mold portion 52 and filled in the cavity 53. A shaped molded product body 41 is formed. The trapezoidal molded product body 41 is in contact with the bonding layer 31 of the cover-forming film 1, and when the bonding layer 31 is composed of a heat-sensitive adhesive, the molten organic polymer for molding is formed. It integrates with the trapezoidal molded product body 41 by the heat of the material. Next, in the mold opening process shown in FIG. 8, the first mold part 51 and the second mold part 52 are opened to take out the molded product, and then the carrier film layer 2 is peeled and removed. A trapezoidal molded product 4 having a concealing layer 42 formed by transferring the concealing body 3 of the concealing body forming film 1 to the main body 41 is obtained.

  In the trapezoidal molded product 4 obtained by the molding method described above, even if an appearance defect such as a weld line or a flow mark occurs in the trapezoidal molded product main body 41, light is irregularly reflected by the concealing layer 42 containing a light scattering component. Therefore, those appearance defects generated in the trapezoidal molded product main body 41 cannot be confirmed from the side where the concealing layer 42 is coated, and the trapezoidal molded product 4 becomes a molded product with excellent design.

  There are no particular restrictions on the material to be molded that constitutes the trapezoidal molded product body 41. For example, polymethacrylic acid resins such as polymethyl methacrylate, polyolefin resins such as polyethylene, polypropylene, and polybutene, and polyvinyl chloride resins. , Aliphatic polyamide resins such as nylon 6 and nylon 66, aromatic polyamide resins such as polyphthalamide, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polyoxymethylene resins, polyether ether ketone resins, Crystalline resins such as fluororesins, polystyrene resins, polysulfone resins, polyethersulfone resins, polyphenylene ether resins, polyarylate resins, polyamideimide resins, polyetherimide resins, acryloni Lil - styrene resin, acrylonitrile - styrene - amorphous resin such as butadiene resin, and an organic polymer material such as a liquid crystal polymer such as aromatic polyester resin and aromatic polyester amide resin. Moreover, the mixture which mix | blended the fillers, such as glass fiber, with the alloy of these organic polymers, or these organic polymers may be sufficient.

  The material to be molded may be an aluminum alloy, a magnesium alloy, other metal materials, various inorganic materials, or the like. In the case where the metal material or various inorganic materials are powders, ceramic powder injection molding, metal powder injection molding, cemented carbide injection molding, and the like can be cited as examples of this type of powder molding method. In these powder moldings, a binder is mixed to impart plasticity to the molding material. As binders, polyvinyl alcohol, polyvinyl bratil, polyethylene glycol, methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxypropyl cellulose, thermoplastic resins such as polyethylene, polypropylene, polystyrene, polyoxymethylene, waxes such as paraffin wax and carnauba wax, etc. Is mentioned.

Examples thereof include steel materials such as S50C, S55C, SCM3, and SCM4, iron alloys such as pure iron and stainless steel, non-ferrous metals such as aluminum and copper, alloys thereof, and inorganic materials such as ceramics.

Embodiment 2. FIG.
FIG. 9 is a cross-sectional view of a concealing body forming film 1 as another example of the concealing body-forming article for explaining the second embodiment of the concealing body-forming article of the present invention. The concealing body forming film 1 of the second embodiment is different from that of the first embodiment in that the bonding layer 31 in the first embodiment is omitted and the concealing body layer 32 is the same as that in the first embodiment. The other components are the same except that they include a light scattering component and have a bonding function such as welding or adhesion to the trapezoidal molded product body 41 (see FIGS. 2 and 3). In addition, the concealment body forming film 1 of the second embodiment includes the light scattering component in the bonding layer 31 of the first embodiment so that both functions of the concealing main body layer and the bonding layer are combined. The concealing main body layer 32 may be omitted. In any case, in the concealing body forming film 1 according to the second embodiment, the concealing body formation is achieved because the concealing function with the trapezoidal molded product body 41 and the concealing function with respect to the weld line and flow mark are achieved by the concealing body layer 32 The structure of the film 1 is simplified, and the production cost can be reduced.

Further, the molded product of the present invention may have various shapes other than the trapezoidal molded product 4. Furthermore, in Embodiment 1 and Embodiment 2, the film for forming a masking body was used as an example of the article for masking body formation of the present invention. Depending on the condition of the defect, a specially shaped object other than a film may be appropriate as the concealer-forming article. Such special shapes are used after being formed into a necessary shape. However, in general, a film form has a wide range of use.

  The concealment main body layer 32 in the first and second embodiments prevents the appearance defect portion of the molded body from being visible based on the light scattering effect of the light scattering component contained therein. As a concealing body layer instead of the scattering component, for example, a concealing function based on light impermeability using a material composed of a light impervious material obtained by mixing a large amount of pigment or inorganic powder in the organic polymer material described above. It may have. In addition to the method using the above-described pigment or inorganic powder, an organic polymer film having a low light transmittance may be formed in a suitable thickness to be a thick layer that is substantially light opaque.

  According to the present invention, a molded product having a good appearance can be produced efficiently and inexpensively without requiring a special molding machine or apparatus or a post-processing step after molding. There is a high possibility of being frequently used in the production of various molded products.
