Description

本発明は、互いに異なる樹脂材料により、互いに隣接した状態で形成された第１基材及び第２基材を備え、第１基材の外表面のうち第２基材が接触していない領域に金属被膜が形成された部分めっき樹脂製品に関する。   The present invention includes a first base material and a second base material that are formed of resin materials different from each other so as to be adjacent to each other, and in a region where the second base material is not in contact with the outer surface of the first base material. The present invention relates to a partially plated resin product having a metal coating formed thereon.

この種の部分めっき樹脂製品としては、例えば、図４に示すものが知られている（例えば、特許文献１、特許文献２参照）。この部分めっき樹脂製品６０は、互いに異なる樹脂材料により、互いに隣接した状態で形成された第１基材６１及び第２基材６３を備えている。第１基材６１は、表裏方向（図４の上下方向）に交差する平面状の一般壁面６２を有している。第２基材６３は、表裏方向に交差する平面状の一般壁面６４を有している。両一般壁面６２，６４は同一平面上に形成されている。第１基材６１の外表面のうち第２基材６３が接触していない領域には金属被膜６５が形成され、第２基材６３には金属被膜６５が形成されていない。なお、金属被膜６５の端末部６７の一部は、第１基材６１からはみ出て第２基材６３上に位置するが、接触しているだけであり、同第２基材６３上に形成（付着）されていない。   As this type of partially plated resin product, for example, one shown in FIG. 4 is known (see, for example, Patent Documents 1 and 2). The partially plated resin product 60 includes a first base material 61 and a second base material 63 which are formed of different resin materials and are adjacent to each other. The first base material 61 has a planar general wall surface 62 that intersects in the front-back direction (vertical direction in FIG. 4). The second base material 63 has a planar general wall surface 64 that intersects in the front-back direction. Both general wall surfaces 62 and 64 are formed on the same plane. The metal coating 65 is formed on a region of the outer surface of the first base 61 which is not in contact with the second base 63, and the metal coating 65 is not formed on the second base 63. Although a part of the terminal portion 67 of the metal coating 65 is located on the second base material 63 so as to protrude from the first base material 61, it is only in contact therewith and is formed on the second base material 63. Not (adhered).

ここで、上記部分めっき樹脂製品６０が車両用外装品に適用される場合には、車両用内装品に適用される場合よりも、金属被膜６５が大きな膜厚で形成される。これは、車両用外装品は、車両用内装品よりも天候等の点で厳しい環境下で使用されるからである。   Here, when the above-described partially plated resin product 60 is applied to the vehicle exterior product, the metal coating 65 is formed with a larger film thickness than when it is applied to the vehicle interior product. This is because the vehicle exterior parts are used in a severer environment than the vehicle interior parts in terms of weather and the like.

一方で、電気めっき工程による金属被膜６５の形成に際し、同金属被膜６５の端末部６７には、他の部位（一般部６６）に対するよりもめっき液の中の電荷が集中しやすく、析出するめっき量が多くなる。そのため、端末部６７の膜厚が一般部６６の膜厚よりも大きくなる。こうした傾向は、部分めっき樹脂製品６０に限らずめっき樹脂製品一般に共通するものである。   On the other hand, when the metal coating 65 is formed by the electroplating process, the electric charge in the plating solution is more likely to concentrate in the terminal portion 67 of the metal coating 65 than in other portions (general portion 66), and thus the deposition plating. The amount increases. Therefore, the film thickness of the terminal portion 67 becomes larger than the film thickness of the general portion 66. This tendency is common not only to the partially-plated resin product 60 but also to the generally-plated resin product.

従って、部分めっき樹脂製品６０が、一般部６６の厚みがもともと大きな車両用外装品に適用されると、車両用内装品に適用される場合に比べ、端末部６７の膜厚と一般部６６の膜厚との差が大きく、端末部６７が一般部６６よりも表側へ膨らむ凸形状となり、見栄え（外観）が低下する。   Therefore, when the partially plated resin product 60 is applied to a vehicle exterior product in which the thickness of the general portion 66 is originally large, the film thickness of the terminal portion 67 and the general portion 66 of the general portion 66 are smaller than those in the vehicle interior product. The difference from the film thickness is large, and the terminal portion 67 has a convex shape that bulges more toward the front side than the general portion 66, and the appearance (appearance) deteriorates.

さらに、上記のように凸形状となった端末部６７の膜厚が、ある一定の値を越える（過大になる）と、その端末部６７に局部的に過剰にめっきが析出して突起６８が形成される、花咲きとも呼ばれる現象が起こり、上記見栄え（外観）を一層低下させる。   Furthermore, when the film thickness of the terminal portion 67 having the convex shape as described above exceeds (excessively) a certain value, excessive plating is locally deposited on the terminal portion 67 to form the protrusion 68. A phenomenon called "flower bloom" occurs, which further deteriorates the appearance (appearance).

また、金属被膜６５の端末部６７は、第２基材６３に対しては、上述したように接触しているだけで付着していない。そのため、端末部６７と第２基材６３との隙間から、金属被膜６５中の銅被膜を腐食させる液体が入り込んだ場合には、その銅被膜が腐食されるおそれがある。特に、上記端末部６７に指等が触れられたり、衝撃が加えられたりした場合には、端末部６７が剥がれて上記隙間が拡大する。隙間に上記液体が入り込みやすくなり、腐食が起こりやすくなる。   Further, the terminal portion 67 of the metal coating 65 is in contact with the second base material 63 as described above, but is not attached thereto. Therefore, when a liquid that corrodes the copper coating in the metal coating 65 enters from the gap between the terminal portion 67 and the second base material 63, the copper coating may be corroded. In particular, when a finger or the like touches the terminal portion 67 or an impact is applied, the terminal portion 67 is peeled off and the gap is enlarged. The above liquid easily enters the gap, and corrosion easily occurs.

本発明は、このような実情に鑑みてなされたものであって、その目的は、金属被膜における端末部の見栄えの向上を図りつつ、同端末部が剥がれるのを抑制することのできる部分めっき樹脂製品を提供することにある。   The present invention has been made in view of such circumstances, the object is to improve the appearance of the terminal portion in the metal coating, the partial plating resin capable of suppressing the peeling of the terminal portion. To provide products.

上記課題を解決する部分めっき樹脂製品は、互いに異なる樹脂材料により、互いに隣接した状態で形成された第１基材及び第２基材を備え、前記第１基材は、表裏方向に交差する平面状の一般壁面を有する第１一般部を備え、前記第２基材は、前記表裏方向に交差する方向に互いに隣接する第２一般部及び第２角部を備え、前記第２一般部は、前記表裏方向に交差する平面状の一般壁面を有し、前記第１基材の外表面のうち前記第２基材が接触していない領域には金属被膜が形成され、同第２基材には金属被膜が形成されていない部分めっき樹脂製品であって、前記第１一般部の前記一般壁面が、前記第２一般部の前記一般壁面に対し裏側へ後退した箇所に形成されることにより、両一般壁面間に段差部が形成されており、前記段差部では、前記金属被膜は、前記第２基材のうち少なくとも前記第２角部に接触した状態で前記第１一般部の前記一般壁面に形成されている。   A partially-plated resin product that solves the above problem includes a first base material and a second base material that are formed of resin materials different from each other so as to be adjacent to each other, and the first base material is a plane that intersects in the front-back direction. A first general portion having a general wall surface, the second base material includes a second general portion and a second corner portion that are adjacent to each other in a direction intersecting the front-back direction, and the second general portion is A metal film is formed on a region of the outer surface of the first base material which is not in contact with the outer surface of the first base material, the metal coating is formed on the second base material. Is a partially-plated resin product in which a metal coating is not formed, and the general wall surface of the first general portion is formed at a position receding to the back side with respect to the general wall surface of the second general portion, A step portion is formed between both general wall surfaces, and at the step portion, Serial metal coating is formed on the common wall surface of the first general portion in contact with at least the second corner of the second substrate.

上記の構成によれば、金属被膜の形成に際し、電気めっき工程が行なわれる。電気めっき工程では、第１基材及び第２基材を備え、かつ金属被膜の形成される前の中間製品が、めっき液に浸漬され、そのめっき液中の陽極電極に陽極電圧が印加される。中間製品に陰極電圧が印加されることにより、第１基材の外表面のうち第２基材が接触していない領域には、マイナス電荷が帯電する。第１基材の周辺に、めっき液中に溶解している金属成分のプラス電荷が集まり、金属被膜が形成される。   According to the above configuration, the electroplating step is performed when forming the metal coating. In the electroplating step, an intermediate product including a first base material and a second base material and before a metal coating is formed is immersed in a plating solution, and an anode voltage is applied to an anode electrode in the plating solution. . By applying the cathode voltage to the intermediate product, a negative electric charge is charged in a region of the outer surface of the first base material which is not in contact with the second base material. Around the first base material, the positive charges of the metal component dissolved in the plating solution are collected to form a metal film.

この際、第１一般部の一般壁面が、第２一般部の一般壁面に対し裏側へ，すなわち、陽極電極から遠ざかる側へ後退した箇所に位置していて、両一般壁面間に段差部が形成されている。陽極電極と第１一般部との間には、第２角部が位置する。この第２角部が壁となり、第１一般部の一般壁面のうち第２基材との境界部分に対し、第２角部側から、めっき液中に溶解している金属成分のプラス電荷が集まるのを妨げる。従って、第１一般部の一般壁面のうち第２基材との境界部分に析出するめっき量が少なくなる。金属被膜の形成に際し、端末部で膜厚が過大となって、その端末部が凸形状になる現象が起こりにくくなる。これに伴い、金属被膜の膜厚が過大になることが原因で突起が形成される、いわゆる花咲き現象も起こりにくくなる。その結果、金属被膜における端末部の見栄え（外観）が向上する。   At this time, the general wall surface of the first general portion is located behind the general wall surface of the second general portion, that is, at a position retracted to the side away from the anode electrode, and a step portion is formed between the general wall surfaces. Has been done. The second corner portion is located between the anode electrode and the first general portion. The second corner serves as a wall, and the positive charge of the metal component dissolved in the plating solution is applied from the second corner side to the boundary portion of the general wall surface of the first general portion with the second base material. Prevent you from gathering. Therefore, the amount of plating deposited on the boundary portion between the general wall surface of the first general portion and the second base material is reduced. When the metal coating is formed, the phenomenon that the terminal portion becomes excessively thick and the terminal portion has a convex shape hardly occurs. Along with this, a so-called flowering phenomenon, in which protrusions are formed due to an excessively large thickness of the metal coating, is less likely to occur. As a result, the appearance (appearance) of the terminal portion of the metal coating is improved.

また、第２角部は、金属被膜の端末部を受け止めることで、その端末部が、表裏方向に交差する方向のうち第２基材側へ延びて形成されるのを規制する。この規制により、金属被膜の端末部の形状が安定し、接触している第２角部から浮き上がりにくい。   In addition, the second corner portion receives the end portion of the metal coating, thereby restricting the formation of the end portion extending to the second base material side in the direction intersecting the front and back directions. Due to this regulation, the shape of the end portion of the metal coating is stable, and it is difficult for the metal coating to lift up from the contacting second corner portion.

金属被膜は、第２一般部の一般壁面に対し裏側へ後退した箇所に位置する。しかも、金属被膜の端末部の隣には、第２角部が位置する。この第２角部は、指等が端末部に近づけられた場合に障壁となり、端末部に触れられるのを妨げる。従って、端末部は、第２基材に対しては接触しているだけで付着していないものの、端末部に指等が触れられたり、衝撃が加えられたりすることが原因で、端末部と第２基材との隙間が拡がることが起こりにくい。   The metal coating is located at a position retracted to the back side with respect to the general wall surface of the second general portion. Moreover, the second corner is located next to the end of the metal coating. The second corner portion serves as a barrier when a finger or the like is brought close to the terminal portion, and prevents the terminal portion from being touched. Therefore, although the terminal portion is only in contact with and not attached to the second base material, the terminal portion may be touched by a finger or the like, or may be impacted, so It is difficult for the gap with the second base material to expand.

上記部分めっき樹脂製品において、前記第１基材は、前記第１一般部に対し前記表裏方向に交差する方向に隣接する第１角部を備え、前記第１基材は、少なくとも前記第１角部において、少なくとも前記第２角部の裏側で、前記表裏方向に交差する方向に重なっており、前記金属被膜は、前記段差部では、前記第２基材のうち前記第２角部のみに接触した状態で前記第１一般部の前記一般壁面に形成されていることが好ましい。   In the above-mentioned partially plated resin product, the first base material includes first corner portions that are adjacent to the first general portion in a direction intersecting the front-back direction, and the first base material is at least the first corner portion. Part, at least on the back side of the second corner part, overlaps in a direction intersecting the front-back direction, and the metal coating contacts only the second corner part of the second base material at the step part. It is preferable that the general wall surface of the first general portion is formed in this state.

上記の構成によれば、第２基材における少なくとも第２角部は、第１基材の少なくとも第１角部の表側に位置し、壁として機能する。電気めっき工程による金属被膜の形成に際し、第２角部は、第１一般部の一般壁面のうち同第２基材との境界部分に対し、第２角部側から、めっき液中に溶解している金属成分のプラス電荷が集まるのを妨げる。   According to the above configuration, at least the second corner portion of the second base material is located on the front side of at least the first corner portion of the first base material, and functions as a wall. During the formation of the metal coating by the electroplating process, the second corner portion is dissolved in the plating solution from the second corner portion side with respect to the boundary portion with the second base material on the general wall surface of the first general portion. Prevents the collection of positive charges of the metal components that are present.

また、第２角部は、金属被膜の端末部が、表裏方向に交差する方向のうち第２基材側へ延びて形成されるのを規制する。また、第２角部は、指等が、同第２角部に隣接する端末部に近づけられた場合に障壁となり、指等が端末部に触れられるのを妨げる。従って、段差部では、金属被膜の端末部が、第２基材に対し第２角部に接触しているだけで付着していないものの、端末部に指等が触れられたり、衝撃が加えられたりすることが原因で、端末部と第２基材との隙間が拡がることが起こりにくい。   Further, the second corner portion restricts the terminal portion of the metal coating film from being formed to extend toward the second base material side in the direction intersecting the front and back directions. Further, the second corner portion serves as a barrier when a finger or the like is brought close to the terminal portion adjacent to the second corner portion, and prevents the finger or the like from being touched by the terminal portion. Therefore, at the stepped portion, although the end portion of the metal coating is in contact with the second base material only at the second corner portion and is not attached, the end portion is touched by a finger or the like, or an impact is applied. It is difficult for the gap between the terminal portion and the second base material to widen due to such a phenomenon.

上記部分めっき樹脂製品において、前記第１基材は、前記第１一般部に対し前記表裏方向に交差する方向に隣接する第１角部を備え、前記第１角部は、前記第２角部から、前記表裏方向に交差する方向へ離れており、前記第２基材は、前記第２角部の裏側に、前記第１角部に隣接する補助角部を有しており、前記金属被膜は、前記段差部では、前記第２基材のうち前記第２角部及び前記補助角部に接触した状態で前記第１一般部の前記一般壁面に形成されていることが好ましい。   In the above-described partially plated resin product, the first base member includes a first corner portion adjacent to the first general portion in a direction intersecting the front-back direction, and the first corner portion is the second corner portion. Are separated from each other in a direction intersecting the front and back directions, and the second base material has an auxiliary corner portion adjacent to the first corner portion on the back side of the second corner portion. Is preferably formed on the general wall surface of the first general portion in a state of being in contact with the second corner portion and the auxiliary corner portion of the second base material in the step portion.

上記の構成によれば、第２基材における第２角部は、同第２基材の補助角部及び第１基材の第１角部よりも表側に位置し、壁として機能する。電気めっき工程による金属被膜の形成に際し、第２角部は、第１角部の補助角部との境界部分に対し、第２角部側から、めっき液中に溶解している金属成分のプラス電荷が集まるのを妨げる。   According to the above configuration, the second corner portion of the second base material is located on the front side with respect to the auxiliary corner portion of the second base material and the first corner portion of the first base material, and functions as a wall. During the formation of the metal coating by the electroplating process, the second corner portion is a positive electrode of the metal component dissolved in the plating solution from the second corner portion with respect to the boundary portion between the first corner portion and the auxiliary corner portion. Prevents the collection of charges.

また、第２角部は、金属被膜の端末部が、表裏方向に交差する方向のうち第２基材側へ延びて形成されるのを規制する。また、第２角部は、指等が、同第２角部に隣接する端末部に近づけられた場合に障壁となり、指等が端末部に触れられるのを妨げる。従って、段差部では、金属被膜の端末部が、第２基材に対し、第２角部及び補助角部において接触するだけであるが、端末部に指等が触れられたり、衝撃が加えられたりすることが原因で、端末部と第２基材との隙間が拡がることが起こりにくい。   Further, the second corner portion restricts the terminal portion of the metal coating film from being formed to extend toward the second base material side in the direction intersecting the front and back directions. Further, the second corner portion serves as a barrier when a finger or the like is brought close to the terminal portion adjacent to the second corner portion, and prevents the finger or the like from being touched by the terminal portion. Therefore, in the step portion, the terminal portion of the metal coating only contacts the second base material at the second corner portion and the auxiliary corner portion, but the terminal portion is touched with a finger or the like, or an impact is applied. It is difficult for the gap between the terminal portion and the second base material to widen due to such a phenomenon.

上記部分めっき樹脂製品において、前記第２角部は前記表裏方向に沿う立壁面を有しており、前記金属被膜の端末部は、前記第２角部に対しては前記立壁面において接触していることが好ましい。   In the above-mentioned partially plated resin product, the second corner portion has an upright wall surface extending along the front and back directions, and the end portion of the metal coating is in contact with the second corner portion on the upright wall surface. Is preferred.

上記の構成のように、第２角部が表裏方向に沿う立壁面を有している場合には、この第２角部の立壁面が壁として機能し、金属被膜の端末部の膜厚が過大になるのを抑制する。立壁面は、金属被膜の端末部を受け止めることで、同端末部が第２基材側へ延びて形成されるのを規制する。さらに、立壁面は、指等が端末部に触れられるのを妨げる。   When the second corner portion has a vertical wall surface along the front and back directions as in the above configuration, the vertical wall surface of the second corner portion functions as a wall, and the film thickness of the end portion of the metal film is To prevent it from becoming excessive. The standing wall receives the end portion of the metal coating, and thereby restricts the formation of the end portion extending toward the second base material side. Further, the standing wall prevents the finger or the like from touching the terminal portion.

上記部分めっき樹脂製品によれば、金属被膜における端末部の見栄えの向上を図りつつ、同端末部が剥がれるのを抑制することができる。   According to the above-described partially plated resin product, it is possible to prevent the terminal portion from peeling off while improving the appearance of the terminal portion in the metal coating.

（第１実施形態）
以下、部分めっき樹脂製品の第１実施形態について、図１及び図２を参照して説明する。部分めっき樹脂製品は、車両用外装品、例えば、フロントグリル、フォグカバー等に具体化される。 (First embodiment)
Hereinafter, a first embodiment of a partially plated resin product will be described with reference to FIGS. 1 and 2. The partially plated resin product is embodied in a vehicle exterior product such as a front grill or a fog cover.

図１（ａ）は、部分めっき樹脂製品１０の一部の断面構造を示している。また、図１（ｂ）は、図１（ａ）の一部を拡大して示している。図１（ａ），（ｂ）では、上側が部分めっき樹脂製品１０の表側（意匠面側）を指し、下側が部分めっき樹脂製品１０の裏側を指している。   FIG. 1A shows a partial cross-sectional structure of the partially plated resin product 10. Moreover, FIG.1 (b) has expanded and shown a part of FIG.1 (a). 1A and 1B, the upper side indicates the front side (design surface side) of the partially plated resin product 10, and the lower side indicates the back side of the partially plated resin product 10.

部分めっき樹脂製品１０の骨格部分は、互いに異なる樹脂材料によって、互いに隣接した状態で形成された第１基材１１及び第２基材２１によって構成されている。
第１基材１１は、ＡＢＳ（アクリロニトリル・ブタジエン・スチレン共重合体）によって形成されている。 The skeleton part of the partially plated resin product 10 is composed of a first base material 11 and a second base material 21 that are formed of resin materials different from each other and are adjacent to each other.
The first base material 11 is formed of ABS (acrylonitrile / butadiene / styrene copolymer).

第１基材１１は、表裏方向（図１（ａ），（ｂ）の上下方向）に対し、直交又は直交に近い状態で交差する方向（左右方向）に互いに隣接する第１一般部１２及び第１角部１４を備えている。第１一般部１２は、上記表裏方向に対し、直交又は直交に近い状態で交差する平面状の一般壁面１３を有している。第１角部１４は、第１基材１１のうち第２基材２１側かつ表側の角部によって構成されており、凸状の湾曲壁面１５を有している。   The first substrate 11 is a first general portion 12 that is adjacent to each other in a direction intersecting with the front-back direction (vertical direction in FIGS. 1A and 1B) in an orthogonal or near-orthogonal state (left-right direction). The first corner portion 14 is provided. The first general portion 12 has a planar general wall surface 13 that intersects the front-back direction in a state orthogonal or nearly orthogonal. The first corner portion 14 is configured by a corner portion on the second base material 21 side and the front side of the first base material 11, and has a convex curved wall surface 15.

この湾曲壁面１５は、金型を用いて樹脂成形を行なう際に形成されるものである。すなわち、第１角部１４は、金型の成形凹部で成形することになるが、成形凹部の内角部を、ＮＣ加工、放電加工、磨き加工等によって角張った形状に形成することが難しい。そのため、第１角部１４には、凸状の湾曲壁面１５が少なからず形成される。この点は、後述する第２角部２４の湾曲壁面２５についても同様である。   The curved wall surface 15 is formed when resin molding is performed using a mold. That is, the first corner portion 14 is molded by the molding concave portion of the mold, but it is difficult to form the inner corner portion of the molding concave portion into an angular shape by NC machining, electric discharge machining, polishing machining, or the like. Therefore, the convex curved wall surface 15 is not a little formed in the first corner portion 14. This also applies to the curved wall surface 25 of the second corner portion 24 described later.

第２基材２１は、ＰＣ（ポリカーボネート）を主成分とした材着樹脂材料によって形成されている。材着樹脂材料は、顔料等の着色材を樹脂材料（ＰＣ）に混合、あるいは光輝材を着色材とともに樹脂材料（ＰＣ）に混合することにより、樹脂自体を着色した材料である。   The second base material 21 is formed of a deposition resin material containing PC (polycarbonate) as a main component. The adhering resin material is a material in which the resin itself is colored by mixing a coloring material such as a pigment with the resin material (PC), or by mixing a glitter material with the coloring material into the resin material (PC).

第２基材２１は、上記表裏方向に対し、直交又は直交に近い状態で交差する方向に互いに隣接する第２一般部２２及び第２角部２４を備えている。第２一般部２２は、上記表裏方向に対し、直交又は直交に近い状態で交差する平面状の一般壁面２３を有している。第２角部２４は、第２基材２１のうち第１基材１１側かつ表側の角部によって構成されており、凸状の湾曲壁面２５を有している。   The second base material 21 includes a second general portion 22 and a second corner portion 24 that are adjacent to each other in a direction that intersects the front-back direction in an orthogonal or near-orthogonal state. The second general portion 22 has a planar general wall surface 23 that intersects the front-back direction in a state of being orthogonal or nearly orthogonal. The second corner portion 24 is formed by a corner portion of the second base material 21 on the first base material 11 side and the front side, and has a convex curved wall surface 25.

第２角部２４は、上記湾曲壁面２５の裏側に隣接する箇所に立壁面２６を有している。立壁面２６は、湾曲壁面２５から上記表裏方向に沿う方向へ延びている。
さらに、第１基材１１の第１角部１４及びその近傍部分が、第２基材２１の第２角部２４及びその近傍部分の裏側で、上記表裏方向に対し、直交又は直交に近い状態で交差する方向（左右方向）に重なっている。ここで、第１角部１４の近傍部分とは、第１一般部１２の第１角部１４との境界部分をいう。また、第２角部２４の近傍部分とは、第２一般部２２の第２角部２４との境界部分をいう。 The second corner portion 24 has a standing wall surface 26 at a location adjacent to the back side of the curved wall surface 25. The standing wall surface 26 extends from the curved wall surface 25 in a direction along the front-back direction.
Further, the first corner portion 14 of the first base material 11 and its vicinity are on the back side of the second corner portion 24 of the second base material 21 and its vicinity, and are in a state of being orthogonal or nearly orthogonal to the front-back direction. It overlaps in the direction intersecting with (left-right direction). Here, the vicinity of the first corner portion 14 refers to a boundary portion of the first general portion 12 with the first corner portion 14. Further, the vicinity of the second corner portion 24 refers to a boundary portion of the second general portion 22 with the second corner portion 24.

上記のように、第１基材１１の第１角部１４及びその近傍部分が、第２基材２１の第２角部２４及びその近傍部分の裏側に形成されることで、第１一般部１２の一般壁面１３は、第２一般部２２の一般壁面２３に対し裏側へ後退した箇所に位置している。両一般壁面１３，２３の間には、０．１ｍｍ〜１．０ｍｍの深さＤの段差部１７が形成されている。   As described above, the first corner portion 14 of the first base material 11 and the vicinity thereof are formed on the back side of the second corner portion 24 of the second base material 21 and the vicinity thereof, so that the first general portion is formed. The general wall surface 13 of 12 is located at a position retracted to the back side with respect to the general wall surface 23 of the second general portion 22. A step portion 17 having a depth D of 0.1 mm to 1.0 mm is formed between the general wall surfaces 13 and 23.

上記第１基材１１及び第２基材２１が一体となったもの（以下「中間製品３０」という）は二色成形を行なうことによって形成されている。二色成形は、樹脂材料の成形方法の一態様であり、異材質（材料）同士を組合わせて一体に成形するものである。二色成形では、一次側となる部分（第１基材１１）を成形してから、二次側となる部分（第２基材２１）を、同一金型内で上記一次側となる部分（第１基材１１）と一体で成形する。   The one in which the first base material 11 and the second base material 21 are integrated (hereinafter referred to as "intermediate product 30") is formed by performing two-color molding. The two-color molding is one mode of a method for molding a resin material, and is a method in which different materials (materials) are combined and integrally molded. In the two-color molding, after molding the part that becomes the primary side (first base material 11), the part that becomes the secondary side (second base material 21) becomes the part that becomes the primary side in the same mold ( It is molded integrally with the first substrate 11).

ここで、第２基材２１の形成材料として用いられたＰＣの融点は、同第２基材２１の形成に先立ち形成された第１基材１１の形成材料として用いられたＡＢＳの融点よりも高い。そのため、第２基材２１の成形に際し、溶融状態のＰＣが金型に供給されると、第１基材１１に対し、その融点よりも温度の高い溶融状態のＰＣが接触する。溶融状態のＰＣの熱が第１基材１１に伝わり、同第１基材１１の第２基材２１との界面が溶融する。第２基材２１が第１基材１１に対し、より強く密着した状態で形成される。   Here, the melting point of PC used as the forming material of the second base material 21 is higher than the melting point of ABS used as the forming material of the first base material 11 formed prior to the formation of the second base material 21. high. Therefore, when the molten PC is supplied to the mold during the molding of the second base material 21, the molten PC having a temperature higher than its melting point comes into contact with the first base material 11. The heat of the molten PC is transmitted to the first base material 11, and the interface between the first base material 11 and the second base material 21 is melted. The second base material 21 is formed in a state of being more closely adhered to the first base material 11.

第１基材１１の外表面のうち第２基材２１が接触していない領域には、めっき処理により金属被膜３５が形成されている。第１実施形態では、金属被膜３５は、銅被膜、ニッケル被膜及びクロム被膜の３種類の被膜が積層されることによって構成されている。銅被膜及びニッケル被膜がそれぞれ５０μｍ程度の膜厚を有するのに対し、クロム被膜は１μｍ以下の膜厚を有している。この金属被膜３５は、段差部１７では、第１一般部１２における一般壁面１３の一部に形成されている。   A metal coating 35 is formed by plating on a region of the outer surface of the first base material 11 which is not in contact with the second base material 21. In the first embodiment, the metal coating 35 is formed by laminating three types of coatings, that is, a copper coating, a nickel coating, and a chromium coating. The copper coating and the nickel coating each have a thickness of about 50 μm, while the chromium coating has a thickness of 1 μm or less. The metal coating 35 is formed on a part of the general wall surface 13 of the first general portion 12 in the step portion 17.

これに対し、第２基材２１の外表面には、金属被膜３５が形成されていない。金属被膜３５の端末部３６は、第２基材２１に対しては、立壁面２６の一般壁面１３との境界部分に接触しているのみである。   On the other hand, the metal coating 35 is not formed on the outer surface of the second base material 21. The terminal portion 36 of the metal coating 35 is only in contact with the second base material 21 at the boundary portion between the standing wall surface 26 and the general wall surface 13.

次に、上記のように構成された第１実施形態の作用及び効果について、上記中間製品３０に部分めっきを施す処理とともに説明する。
最初に、中間製品３０を図２に示す治具４０に取付ける。治具４０は、治具本体４１と、その治具本体４１に設けられ、かつ中間製品３０に設けられた電気接点部３１を挟み込む金属製のクリップ（図示略）と、治具本体４１を搬送機４２に引っ掛けるフック部４３とを備えている。搬送機４２は、中間製品３０の取付けられた治具４０を、上下方向及び水平方向に移動させる。この搬送機４２により、治具４０をめっき槽４４の外の位置まで移動させて導電性付与工程を行なう。その後に、治具４０を搬送機４２により各種めっき槽４４まで移動させて電気めっき工程を行なう。 Next, the operation and effect of the first embodiment configured as described above will be described together with the process of performing partial plating on the intermediate product 30.
First, the intermediate product 30 is attached to the jig 40 shown in FIG. The jig 40 conveys the jig main body 41, a metal clip (not shown) provided on the jig main body 41 and sandwiching the electric contact portion 31 provided on the intermediate product 30, and the jig main body 41. And a hook portion 43 hooked on the machine 42. The carrier 42 moves the jig 40 to which the intermediate product 30 is attached in the vertical direction and the horizontal direction. With this carrier 42, the jig 40 is moved to a position outside the plating tank 44 to perform the conductivity imparting step. After that, the jig 40 is moved to various plating tanks 44 by the carrier 42 and an electroplating process is performed.

＜導電性付与工程＞
この工程では、治具４０とともに中間製品３０に対して次の各表面処理を行なう。まず、中間製品３０に対し表面調整を行なうことにより、同中間製品３０の外表面に付着しているゴミ、油等の汚れを除去する。次に、エッチング液を用いて中間製品３０にエッチングを行なうことにより、中間製品３０の外表面を化学的に粗化する。次に、中間製品３０の外表面を酸で中和して、エッチング成分の一種である六価クロムを還元除去する。次に、中間製品３０にキャタリストを行なうことで、中間製品３０の粗化された外表面に、吸着力が強く還元力のある触媒（Ｐｄ−Ｓｎ化合物）を吸着させる。次に、中間製品３０に対しアクセレータを行ない、中間製品３０の外表面に付着していたＳｎを除去し、Ｐｄを活性化させる。次に、中間製品３０を無電解めっき槽に浸漬して、中間製品３０に対し無電解めっきを行なうことにより、無電解めっき層を形成する。このようにして導電性付与工程が行なわれることにより、中間製品３０の外表面に導電性が付与される。 <Conductivity imparting step>
In this step, the following surface treatments are performed on the intermediate product 30 together with the jig 40. First, surface adjustment is performed on the intermediate product 30 to remove dirt such as dust and oil attached to the outer surface of the intermediate product 30. Next, the intermediate product 30 is etched with an etching solution to chemically roughen the outer surface of the intermediate product 30. Next, the outer surface of the intermediate product 30 is neutralized with an acid to reduce and remove hexavalent chromium, which is one of the etching components. Next, by performing a catalyst on the intermediate product 30, a catalyst (Pd—Sn compound) having a strong adsorptive power and a reducing power is adsorbed on the roughened outer surface of the intermediate product 30. Next, the intermediate product 30 is accelerated to remove Sn attached to the outer surface of the intermediate product 30 and activate Pd. Next, the intermediate product 30 is immersed in an electroless plating bath, and electroless plating is performed on the intermediate product 30 to form an electroless plating layer. Conductivity is imparted to the outer surface of the intermediate product 30 by performing the conductivity imparting step in this manner.

＜電気めっき工程＞
この工程では、図２に示すように、中間製品３０を治具４０とともに各種めっき槽４４に浸漬する。各種めっき槽４４には、それぞれ対応するめっき液４５が貯留されていて、その中には陽極電極４６が備えられている。陽極電極４６に対し陽極電圧を印加する。また、中間製品３０に対し、クリップによって挟み込まれた電気接点部３１を通じて陰極電圧を印加する。中間製品３０の外表面には、上述した導電性の無電解めっき層が形成されているため、同外表面はマイナスに帯電する。 <Electroplating process>
In this step, as shown in FIG. 2, the intermediate product 30 is immersed in various plating baths 44 together with the jig 40. The various plating tanks 44 store the corresponding plating solutions 45, and the anodes 46 are provided therein. An anode voltage is applied to the anode electrode 46. Further, the cathode voltage is applied to the intermediate product 30 through the electric contact portion 31 sandwiched by the clip. Since the electroconductive electroless plating layer described above is formed on the outer surface of the intermediate product 30, the outer surface is negatively charged.

各種電気めっきでは、酸活性、ストライクめっき、銅めっき、半光沢ニッケルめっき、光沢ニッケルめっき、分散ストライクニッケルめっき、クロムめっきを順に行なう。
そのため、上記電気めっき工程が行なわれて、中間製品３０に陰極電圧が印加されると、第１基材１１の外表面のうち、第２基材２１が接触していない領域には、マイナス電荷が帯電する。従って、第１基材１１の周辺に、めっき液４５中に溶解している金属成分のプラス電荷が集まり、金属被膜３５が形成される。 In various electroplating, acid activation, strike plating, copper plating, semi-bright nickel plating, bright nickel plating, dispersed strike nickel plating, and chromium plating are performed in order.
Therefore, when the above electroplating process is performed and a cathode voltage is applied to the intermediate product 30, a negative charge is applied to a region of the outer surface of the first base material 11 which is not in contact with the second base material 21. Is charged. Therefore, the positive charges of the metal components dissolved in the plating solution 45 are collected around the first base material 11 to form the metal coating 35.

この際、第１一般部１２の一般壁面１３が、第２一般部２２の一般壁面２３に対し裏側へ、すなわち陽極電極４６から遠ざかる側へ後退した箇所に位置していて、両一般壁面１３，２３間に段差部１７が形成されている。陽極電極４６と、第１一般部１２及び第１角部１４との間には、第２角部２４が位置する。この第２角部２４が壁となり、第１一般部１２の一般壁面１３のうち立壁面２６との境界部分に対し、第２角部２４側（図１（ａ），（ｂ）の左側）から、めっき液４５中に溶解している金属成分のプラス電荷が集まるのを妨げる。従って、第１一般部１２の一般壁面１３のうち立壁面２６との境界部分に析出するめっき量が少なくなる。金属被膜３５の形成に際し、端末部３６で膜厚が過大となって、その端末部３６が凸形状になる現象が起こりにくくなる。これに伴い、金属被膜３５の膜厚が過大になることが原因で突起が形成される、いわゆる花咲き現象が起こりにくくなる。   At this time, the general wall surface 13 of the first general portion 12 is located behind the general wall surface 23 of the second general portion 22, that is, at a position retracted to the side away from the anode electrode 46. A step portion 17 is formed between 23. The second corner portion 24 is located between the anode electrode 46 and the first general portion 12 and the first corner portion 14. The second corner portion 24 serves as a wall, and the second corner portion 24 side (the left side in FIGS. 1A and 1B) with respect to the boundary portion of the general wall surface 13 of the first general portion 12 with the standing wall surface 26. Therefore, it prevents the positive charges of the metal component dissolved in the plating solution 45 from collecting. Therefore, the amount of plating deposited on the boundary portion of the general wall surface 13 of the first general portion 12 with the standing wall surface 26 is reduced. When the metal coating 35 is formed, the phenomenon that the terminal portion 36 has an excessively large thickness and the terminal portion 36 has a convex shape is unlikely to occur. Along with this, the so-called flower bloom phenomenon in which protrusions are formed due to the excessive thickness of the metal coating 35 is less likely to occur.

また、第２角部２４の立壁面２６は、金属被膜３５の端末部３６を受け止めることで、その端末部３６が、表裏方向に交差する方向のうち第２基材２１側へ延びて形成されるのを規制する。この規制により、金属被膜３５の端末部３６の形状が安定し、接触している立壁面２６から浮き上がりにくい。   Further, the standing wall surface 26 of the second corner portion 24 is formed by receiving the end portion 36 of the metal coating 35, so that the end portion 36 extends toward the second base material 21 side in the direction intersecting the front-back direction. Regulate that. Due to this regulation, the shape of the end portion 36 of the metal coating 35 is stable, and it is difficult for the metal coating 35 to lift from the contacting vertical wall surface 26.

その後、乾燥と、治具４０の取り外し及び検査とを順に行なうと、外表面の一部に金属被膜３５の形成された、目的とする部分めっき樹脂製品１０が得られる。
得られた部分めっき樹脂製品１０では、上述したように、金属被膜３５の端末部３６が、同金属被膜３５の他の箇所と同程度の膜厚を有している。端末部３６は凸形状とならず平坦な形状をなしており、花咲きと呼ばれる突起を有していない。このことから、金属被膜３５の端末部３６における見栄え（外観）は、金属被膜６５の端末部６７が凸形状となったり、突起６８が生じたりする従来の部分めっき樹脂製品６０よりも向上する。 After that, the drying, the removal of the jig 40, and the inspection are performed in order to obtain the intended partially plated resin product 10 having the metal coating 35 formed on a part of the outer surface.
In the obtained partially-plated resin product 10, as described above, the terminal portion 36 of the metal coating 35 has the same film thickness as the other portions of the metal coating 35. The terminal portion 36 does not have a convex shape but a flat shape, and does not have a protrusion called a flower bloom. From this, the appearance (appearance) of the end portion 36 of the metal coating 35 is improved as compared with the conventional partial plating resin product 60 in which the end portion 67 of the metal coating 65 has a convex shape or the protrusion 68 is formed.

また、上記のように、金属被膜３５の端末部３６が浮き上がりにくいことや、同端末部３６の形状が安定し、同端末部３６の外縁の位置ばらつきが小さいことも、金属被膜３５の端末部３６における見栄え（外観）の向上に寄与している。   Further, as described above, the terminal portion 36 of the metal coating 35 is hard to lift, the shape of the terminal portion 36 is stable, and the position variation of the outer edge of the terminal portion 36 is small. This contributes to the improvement of the appearance (appearance) in No. 36.

また、部分めっき樹脂製品１０では、金属被膜３５は、第２一般部２２の一般壁面２３に対し裏側へ後退した箇所に位置している。しかも、金属被膜３５の端末部３６の隣には、第２角部２４の立壁面２６が位置する。この立壁面２６は、指等が端末部３６に近づけられた場合に障壁となり、端末部３６に触れられるのを妨げる。従って、端末部３６は、立壁面２６に対しては接触しているだけで付着していないものの、端末部３６には、指等が触れられたり、衝撃が加えられたりすることが原因で、端末部３６と第２基材２１との隙間が拡がることが起こりにくい。金属被膜３５中の銅被膜を腐食させる液体が隙間に入り込みにくく、銅被膜が腐食されるのを抑制することができる。その結果、金属被膜３５の耐剥がれ性及び防錆性を向上させることができる。   Further, in the partially plated resin product 10, the metal coating 35 is located at a position retracted to the back side with respect to the general wall surface 23 of the second general portion 22. Moreover, the standing wall surface 26 of the second corner portion 24 is located next to the end portion 36 of the metal coating 35. The standing wall surface 26 serves as a barrier when a finger or the like is brought close to the terminal portion 36, and prevents the terminal portion 36 from being touched. Therefore, although the terminal portion 36 is only in contact with the standing wall surface 26 and is not attached, the terminal portion 36 may be touched by a finger or the like, or an impact may be applied, It is difficult for the gap between the terminal portion 36 and the second base material 21 to expand. The liquid that corrodes the copper coating in the metal coating 35 is unlikely to enter the gap, and the corrosion of the copper coating can be suppressed. As a result, it is possible to improve the peeling resistance and rust prevention of the metal coating 35.

上記のように端末部３６の見栄えを向上させ、かつ金属被膜３５の耐剥がれ性及び防錆性を向上させる効果は、段差部１７の深さＤが、０．１ｍｍ〜１．０ｍｍに設定された場合に良好に発揮される。   As described above, the effect of improving the appearance of the terminal portion 36 and improving the peeling resistance and the rust prevention of the metal coating 35 is that the depth D of the step portion 17 is set to 0.1 mm to 1.0 mm. It is demonstrated well when

（第２実施形態）
次に、部分めっき樹脂製品の第２実施形態について、図３を参照して説明する。
第２実施形態は、第１基材１１が第１一般部１２及び第１角部１４を備え、第２基材２１が第２一般部２２及び第２角部２４を備えており、第１一般部１２の一般壁面１３と第２一般部２２の一般壁面２３との間に段差部１７が形成されている点で第１実施形態と共通する。 (Second embodiment)
Next, a second embodiment of the partially plated resin product will be described with reference to FIG.
In the second embodiment, the first base material 11 includes the first general portion 12 and the first corner portion 14, and the second base material 21 includes the second general portion 22 and the second corner portion 24. It is common to the first embodiment in that a step portion 17 is formed between the general wall surface 13 of the general portion 12 and the general wall surface 23 of the second general portion 22.

しかし、第２実施形態では、第１実施形態とは異なり、第１角部１４が第２角部２４よりも裏側で、その第２角部２４から、上記表裏方向に交差する方向（図３の右方）へ離れている。第２基材２１は、第２角部２４の裏側に、上記第１角部１４に隣接する補助角部２７を有している。補助角部２７は、上記表裏方向に対し直交又は直交に近い状態で交差する段差壁面２８を有している。段差壁面２８は、第１基材１１の一般壁面１３と同一平面上に位置しており、同一般壁面１３に繋がっている。補助角部２７は、上記段差壁面２８の裏側に凹状の湾曲壁面２９を有しており、この湾曲壁面２９において第１角部１４の湾曲壁面１５に密着している。   However, in the second embodiment, unlike the first embodiment, the first corner portion 14 is on the back side of the second corner portion 24, and the direction from the second corner portion 24 in the front-back direction crossing direction (FIG. 3). To the right of). The second base member 21 has an auxiliary corner portion 27 adjacent to the first corner portion 14 on the back side of the second corner portion 24. The auxiliary corner portion 27 has a step wall surface 28 that intersects the front-back direction in a state orthogonal or nearly orthogonal. The step wall surface 28 is located on the same plane as the general wall surface 13 of the first base material 11, and is connected to the general wall surface 13. The auxiliary corner portion 27 has a concave curved wall surface 29 on the back side of the step wall surface 28 and is in close contact with the curved wall surface 15 of the first corner portion 14 at this curved wall surface 29.

金属被膜３５は、段差部１７では、第２角部２４の立壁面２６の一部と、補助角部２７の段差壁面２８とに接触した状態で、第１一般部１２の一般壁面１３に形成されている。補助角部２７の段差壁面２８との接触の分、端末部３６の第２基材２１との接触面積が第１実施形態よりも大きくなっている。   In the step portion 17, the metal coating 35 is formed on the general wall surface 13 of the first general portion 12 while being in contact with a part of the standing wall surface 26 of the second corner portion 24 and the step wall surface 28 of the auxiliary corner portion 27. Has been done. The contact area of the terminal portion 36 with the second base material 21 is larger than that in the first embodiment by the amount of contact with the stepped wall surface 28 of the auxiliary corner portion 27.

上記以外の構成は第１実施形態と同様である。そのため、第１実施形態で説明したものと同様の要素には同一の符号を付し、重複する説明を省略する。
上記構成の第２実施形態では、第２基材２１における第２角部２４は、補助角部２７及び第１角部１４よりも表側に位置し、壁として機能する。そのため、電気めっき工程では、第２角部２４は、第１角部１４の補助角部２７との境界部分に対し、第２角部２４側（図３の左側）から、めっき液４５中に溶解している金属成分のプラス電荷が集まるのを妨げる。また、第２角部２４の立壁面２６は、金属被膜３５の端末部３６を受け止め、同端末部３６が、表裏方向に交差する方向のうち第２基材２１側へ延びて形成されるのを規制する。 The configuration other than the above is the same as that of the first embodiment. Therefore, the same elements as those described in the first embodiment are designated by the same reference numerals, and duplicate description will be omitted.
In the second embodiment having the above configuration, the second corner portion 24 of the second base material 21 is located on the front side with respect to the auxiliary corner portion 27 and the first corner portion 14 and functions as a wall. Therefore, in the electroplating step, the second corner portion 24 enters the plating solution 45 from the second corner portion 24 side (left side in FIG. 3) with respect to the boundary portion of the first corner portion 14 with the auxiliary corner portion 27. Prevents the positive charge of the dissolved metal components from collecting. The standing wall surface 26 of the second corner portion 24 receives the end portion 36 of the metal coating 35, and the end portion 36 is formed to extend toward the second base material 21 side in the direction intersecting the front-back direction. Regulate.

得られた部分めっき樹脂製品１０では、第２角部２４の立壁面２６は、指等が同立壁面２６に隣接する端末部３６に近づけられた場合に障壁となり、指等が端末部３６に触れられるのを妨げる。そのため、段差部１７では、金属被膜３５の端末部３６が、第２基材２１に対し、第２角部２４の立壁面２６の一部と補助角部２７の段差壁面２８とに接触しているだけであるが、端末部３６に指等が触れられたり、衝撃が加えられたりすることが原因で、端末部３６と第２基材２１との隙間が拡がることが起こりにくい。   In the obtained partially plated resin product 10, the standing wall surface 26 of the second corner portion 24 becomes a barrier when a finger or the like approaches the terminal portion 36 adjacent to the standing wall surface 26, and the finger or the like touches the terminal portion 36. Prevent it from being touched. Therefore, in the step portion 17, the end portion 36 of the metal coating 35 contacts the second base material 21 with a part of the standing wall surface 26 of the second corner portion 24 and the step wall surface 28 of the auxiliary corner portion 27. However, it is difficult for the gap between the terminal portion 36 and the second base material 21 to widen due to the fact that the terminal portion 36 is touched with a finger or the like or an impact is applied.

従って、第２実施形態によっても第１実施形態と同様に、金属被膜３５における端末部３６の見栄えの向上を図ることができるとともに、金属被膜３５の耐剥がれ性及び防錆性を向上させることができる。こうした効果は、第１実施形態と同様に、段差部１７の深さＤが、０．１ｍｍ〜１．０ｍｍに設定された場合に良好に発揮される。   Therefore, according to the second embodiment as well as the first embodiment, the appearance of the terminal portion 36 in the metal coating 35 can be improved, and the peeling resistance and the rust prevention of the metal coating 35 can be improved. it can. Similar to the first embodiment, such an effect is excellently exhibited when the depth D of the step portion 17 is set to 0.1 mm to 1.0 mm.

なお、上記各実施形態は、これを以下のように変更した変形例として実施することもできる。
・各実施形態において、金属被膜３５は、１層又は２層の皮膜によって構成されてもよいし、４層以上の複数の皮膜によって構成されてもよい。 In addition, each of the above-described embodiments can be implemented as a modified example in which the following modifications are made.
In each embodiment, the metal coating 35 may be composed of one layer or two layers, or may be composed of four or more layers.

・各実施形態において、上記表裏方向に直交又は直交に近い状態で交差する方向における第２角部２４の立壁面２６の位置が変更されてもよい。例えば、立壁面２６は、図３において二点鎖線で示すように、第１実施形態における立壁面２６と、第２実施形態における立壁面２６との中間の位置に形成されてもよい。この場合、変形例における立壁面２６は、第１基材１１における第１一般部１２と第１角部１４との境界部分に位置する。このように変更された場合にも、上記第１及び第２実施形態と同様の作用及び効果が得られる。   -In each embodiment, the position of the standing wall surface 26 of the second corner portion 24 may be changed in the direction intersecting the front-back direction at right angles or in a state close to being orthogonal. For example, the standing wall surface 26 may be formed at an intermediate position between the standing wall surface 26 in the first embodiment and the standing wall surface 26 in the second embodiment, as shown by the chain double-dashed line in FIG. 3. In this case, the standing wall surface 26 in the modified example is located at the boundary portion between the first general portion 12 and the first corner portion 14 of the first base material 11. Even when modified in this way, the same operation and effect as those of the first and second embodiments can be obtained.

・段差部１７の深さＤが浅い場合には、金属被膜３５は、その端末部３６が、第２角部２４の立壁面２６に代えて湾曲壁面２５に接触した状態で、第１一般部１２の一般壁面１３上に形成されてもよい。   When the depth D of the step portion 17 is shallow, the metal coating 35 has the end portion 36 thereof in contact with the curved wall surface 25 instead of the standing wall surface 26 of the second corner portion 24 in the first general portion. It may be formed on 12 general wall surfaces 13.
