以下に、本発明の実施の形態について、添付図面を参照しながら説明する。まず、本製造方法の基本手順について説明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings. First, the basic procedure of the manufacturing method will be described.

本製造方法は、熱硬化性樹脂を金型１０に供給して成形する樹脂成形品の製造方法である。この金型１０の意匠面２０はマット加工（しぼ加工）がなされたマット面とされている。この製造方法は、意匠面２０に所望の形状の耐熱性粘着テープ１５を貼り付けたのち、熱硬化性樹脂２５を、マット面が露出した部位２２と、マット面に貼り付けたテープ１５の外表面２３とに跨るように、金型１０内に供給する手順とされる。以下、耐熱性粘着テープ１５はテープ１５と略す。 This manufacturing method is a method for manufacturing a resin molded product in which a thermosetting resin is supplied to the mold 10 and molded. The design surface 20 of the mold 10 is a mat surface that has been subjected to mat processing (texturing). In this manufacturing method, a heat-resistant adhesive tape 15 having a desired shape is attached to the design surface 20, and then a thermosetting resin 25 is applied to the portion 22 where the mat surface is exposed and the tape 15 attached to the mat surface. The procedure is such that the mold 10 is supplied so as to straddle the surface 23. Hereinafter, the heat resistant adhesive tape 15 is abbreviated as the tape 15.

このように、本製造方法で用いる金型１０は、本製造方法の手順を実行することにより、金型１０の意匠面２０がテープ１５の貼り付けにより加工される。そして、その金型１０を用いて樹脂成形することより、成形対象である樹脂成形品３０の表面模様３１に対応した模様面２１が形成される。 As described above, in the mold 10 used in the present manufacturing method, the design surface 20 of the mold 10 is processed by attaching the tape 15 by executing the procedure of the present manufacturing method. Then, by performing resin molding using the mold 10, the pattern surface 21 corresponding to the surface pattern 31 of the resin molded product 30 which is the molding target is formed.

以下、本製造方法の詳細について説明する。なお、本製造方法は種々の形状の樹脂成形品３０に対応したものであるが、図例では、図２（ｃ）に示すように、製造対象である樹脂成形品３０が平面視正方形状の板体としたものを例示する。また、本例では意匠面２０は上型１１のキャビティ面に形成されている。 Hereinafter, the details of this manufacturing method will be described. The present manufacturing method is applicable to the resin molded products 30 having various shapes, but in the illustrated example, as shown in FIG. 2C, the resin molded product 30 to be manufactured has a square shape in plan view. A plate body is exemplified. Further, in this example, the design surface 20 is formed on the cavity surface of the upper mold 11.

樹脂成形品３０の原材料としては、フェノール樹脂やエポキシ樹脂などの熱硬化性樹脂２５が用いられる。熱硬化性樹脂２５には光輝性の顔料が含有されてもよいが、これには限られない。光輝性の顔料としては、薄片状雲母の表面に二酸化チタン層を形成させたものや、ガラスフレークに金属、金属酸化物をコートしたものなどが用いられる。 As a raw material for the resin molded product 30, a thermosetting resin 25 such as a phenol resin or an epoxy resin is used. The thermosetting resin 25 may contain a bright pigment, but is not limited thereto. As the glittering pigment, there are used those in which a titanium dioxide layer is formed on the surface of flaky mica, and those in which glass flakes are coated with a metal or a metal oxide.

本製造方法に用いる金型１０の意匠面２０は、図１（ａ）に示すように、加工前には、その意匠面２０の全体がマット面（意匠面２０）とされている。 As shown in FIG. 1A, the design surface 20 of the mold 10 used in the present manufacturing method is a matte surface (design surface 20) as a whole before processing.

なお、図１（ａ）（ｂ）に示した意匠面２０の模式平面図では、マット面がクロスハッチングで模式的に示してある。また、樹脂成形品３０の表面模様３１のうちのマット面に対応した地模様部３２についても、図２（ｃ）に示した模式的斜視図においてクロスハッチングで模式的に示してある。また、図２（ａ）（ｂ）に示した金型１０の模式的縦断面図では、マット面が連続凹凸であるように模式的に示してある。 In the schematic plan view of the design surface 20 shown in FIGS. 1A and 1B, the mat surface is schematically shown by cross hatching. Further, the ground pattern portion 32 corresponding to the matte surface of the surface pattern 31 of the resin molded product 30 is also schematically shown by cross hatching in the schematic perspective view shown in FIG. Further, in the schematic vertical sectional views of the mold 10 shown in FIGS. 2A and 2B, the mat surface is schematically shown as having continuous irregularities.

処理手順としては、まず、図１（ａ）に示した金型１０の加工前の意匠面２０に対し、所望の模様に対応してテープ１５が貼り付けられる。具体的には、成形する樹脂成形品３０の表面模様３１が図２（ｃ）に示すようなクロス模様であれば、その表面模様３１に対応した模様面２１が、図１（ｂ）のようにテープ１５を縦横に貼り付けること加工、形成される。 As the processing procedure, first, the tape 15 is attached to the unprocessed design surface 20 of the mold 10 shown in FIG. Specifically, if the surface pattern 31 of the resin molded product 30 to be molded is a cross pattern as shown in FIG. 2C, the pattern surface 21 corresponding to the surface pattern 31 is as shown in FIG. 1B. The tape 15 is processed and formed by attaching the tape 15 vertically and horizontally.

テープ１５としてはセロハンテープが好適に用いられる。セロハンテープは難膨潤性であり、溶融状態の熱硬化性樹脂２５で膨潤して粘着性が低下する可能性が低いため、樹脂成形に適している。また、セロハンテープは成形温度が１００℃程度でも変形しないため、同一模様の複数の樹脂成形品３０の繰り返し成形に利用できる。成型温度をさらに高温（例えば、１２０℃程度）にする場合、ポリイミド製のテープを用いればよい。また、粘着剤付きのアルミテープを用いてもよい。 Cellophane tape is preferably used as the tape 15. Cellophane tape is difficult to swell, and is unlikely to swell with the thermosetting resin 25 in a molten state to reduce its adhesiveness, and is therefore suitable for resin molding. Further, since the cellophane tape does not deform even at a molding temperature of about 100° C., it can be used for repeatedly molding a plurality of resin molded products 30 having the same pattern. When the molding temperature is further increased (for example, about 120° C.), a polyimide tape may be used. Alternatively, an aluminum tape with an adhesive may be used.

また、テープ１５の貼り付けにより形成される、樹脂成形品３０のテープ模様部３３（図２（ｃ）参照）を、全体的に凹凸なく平坦に形成するためには、図１（ｂ）に示すようなテープ１５貼り付けを行えばよい。つまり、テープ１５の縦横のクロス部分が突出しないように、縦横に配するテープ１５のすくなくとも一方が分断された状態に貼り付けられればよい。もちろん、厚みの薄いテープ１５を用いる場合などには、縦横に配するテープ１５が重なるように貼り付けしてもよい。 Further, in order to form the tape pattern portion 33 (see FIG. 2C) of the resin molded product 30 formed by pasting the tape 15 flat without any unevenness, in FIG. The tape 15 as shown may be attached. That is, in order to prevent the vertical and horizontal cross portions of the tape 15 from protruding, at least one of the vertical and horizontal tapes 15 may be attached in a separated state. Of course, when using a thin tape 15, the tapes 15 arranged vertically and horizontally may be attached so as to overlap each other.

図２（ａ）（ｂ）に示すように、上記のようにテープ１５による加工がなされてなる模様面２１を有した上型１１と、下型１２との間にできる空間に熱硬化性樹脂２５が注入され、熱硬化性樹脂２５が硬化して樹脂成形品３０が成形される。図２（ａ）（ｂ）に示すように、熱硬化性樹脂２５は、模様面２１におけるマット面が露出した部位２２と、模様面２１における貼り付けられたテープ１５の外表面２３とに跨るように供給される。 As shown in FIGS. 2A and 2B, a thermosetting resin is provided in a space formed between the upper mold 11 and the lower mold 12 having the pattern surface 21 processed by the tape 15 as described above. 25 is injected, the thermosetting resin 25 is cured, and the resin molded product 30 is molded. As shown in FIGS. 2A and 2B, the thermosetting resin 25 extends over the portion 22 of the pattern surface 21 where the matte surface is exposed and the outer surface 23 of the tape 15 attached on the pattern surface 21. As supplied.

このようにして、図２（ｃ）に示すような樹脂成形品３０が成形される。この樹脂成形品３０の表面には、テープ模様部３３と、そのクロス状のテープ模様部３３により分離された地模様部３２とよりなる表面模様３１が形成される。図２（ｃ）の部分拡大正面図に示すように、地模様部３２は微細な凹凸が表れ、テープ模様部３３は平坦な面として表れる。なお、図２（ｃ）の拡大正面図に示すように、テープ模様部３３は、テープ１５の厚みにより、周囲の地模様部３２よりも凹んだ状態となることもある。 In this way, the resin molded product 30 as shown in FIG. 2C is molded. A surface pattern 31 including a tape pattern portion 33 and a ground pattern portion 32 separated by the cross-shaped tape pattern portion 33 is formed on the surface of the resin molded product 30. As shown in the partially enlarged front view of FIG. 2C, the ground pattern portion 32 has fine irregularities, and the tape pattern portion 33 has a flat surface. As shown in the enlarged front view of FIG. 2C, the tape pattern portion 33 may be recessed from the surrounding ground pattern portion 32 depending on the thickness of the tape 15.

また、テープ１５の貼り付け方次第では、図３に示すように、地模様部３２およびテープ模様部３３のそれぞれが不規則形状の表面模様３１を有した樹脂成形品３０を成形することもできる。その他、テープ模様部３３を枠部分に形成としたものや、テープ模様部３３を点在模様としたものなど種々の表面模様のものも、本製造方法により成形することができる。 Further, depending on how to attach the tape 15, as shown in FIG. 3, it is also possible to mold the resin molded product 30 in which each of the ground pattern portion 32 and the tape pattern portion 33 has an irregular surface pattern 31. In addition, various surface patterns such as the tape pattern portion 33 formed in the frame portion and the tape pattern portion 33 in the dotted pattern can be formed by the present manufacturing method.

以上のように、本製造方法によれば、金型１０の意匠面２０へのテープ１５の貼り付けをするだけで、簡単に表面模様３１を有した樹脂成形品３０を成形することができる。テープ１５は簡易に貼り剥がしができるので、同じ金型１０を用いて異なる表面模様３１の樹脂成形品３０を成形することができる。つまり、外形が同じで表面模様３１が種々異なる樹脂成形品３０を製造したい場合でも、表面模様３１におうじて複数の金型１０を準備する必要がなく、そのため少量多種生産の場合にも低生産コスト化を図ることができる。もちろん、テープ１５を外したのちに、元の意匠面２０のままで樹脂成形をすることもできる。 As described above, according to the present manufacturing method, the resin molded product 30 having the surface pattern 31 can be easily formed only by attaching the tape 15 to the design surface 20 of the mold 10. Since the tape 15 can be easily peeled off, the resin mold 30 having different surface patterns 31 can be molded using the same mold 10. In other words, even when it is desired to manufacture resin molded products 30 having the same outer shape but different surface patterns 31, it is not necessary to prepare a plurality of molds 10 for the surface patterns 31, and therefore low production is possible even in the case of small-volume multi-production. Cost can be reduced. Of course, after removing the tape 15, resin molding can be performed with the original design surface 20 as it is.

さらに、テープ１５として難膨潤性のものなどの劣化、変形しにくいものを用いれば、同一模様で多数の樹脂成形品３０の成形にも利用でき、それによってもさらに低コスト化に寄与することができる。また、難膨潤性のテープ１５を用いれば樹脂成形品３０の表面模様の品質も一定する。 Furthermore, if a tape that is difficult to deteriorate or deform such as a tape 15 that is difficult to swell is used, it can be used for molding a large number of resin molded products 30 with the same pattern, which also contributes to cost reduction. it can. In addition, the quality of the surface pattern of the resin molded product 30 becomes constant by using the tape 15 which is difficult to swell.

また、光輝性の顔料が含有された熱硬化性樹脂２５を用いれば、成形された樹脂成形品３０の表面模様３１のうちのテープ模様部３３は光の反射により光沢が顕著に表出し、めりはりのある表面模様３１に仕上げることができる。また、地模様部３２の乱反射による独特の意匠を表現することもできる。 Further, when the thermosetting resin 25 containing the luster pigment is used, the tape pattern portion 33 of the surface pattern 31 of the molded resin molded product 30 shows a remarkable gloss due to the reflection of light. It is possible to finish the surface pattern 31 with a stickiness. It is also possible to express a unique design due to the irregular reflection of the ground pattern portion 32.
