Description

本発明は、例えば車両等に搭載されるフロントランプ、テールランプあるいはエンブレム等の成膜がなされた成形体である成膜成形体の製造方法および成膜成型用の製造装置の技術分野に属するものである。   The present invention belongs to the technical field of a manufacturing method of a film-forming molded body, which is a molded body on which a film such as a front lamp, a tail lamp, or an emblem mounted on a vehicle or the like is formed and a manufacturing apparatus for film-forming molding. is there.

一般に、この種成膜成型品のなかには、例えば、車両用のエンブレム等の部品ように、部材表面に着色効果や反射効果等の効果を有する素材で被覆して、意匠性を高めたものがあり、この製造方法として、例えば、部材表面を装飾クロム鍍金皮膜で被覆して形成したものがある（例えば、特許文献１参照。）。
ところで今日、鍍金に使用する六価クロムは人体に有害な物質であって、環境汚染による公害問題を発生することから規制の対象ともなっており、脱クロムが要求されている。
この改善策として、基材表面に真空蒸着やスパッタリング等の成膜装置で成膜を形成し、さらに、該成膜の表面を樹脂材で被覆したものがある（例えば、特許文献２参照。）。
ところがこのようなものは、射出成形した基材を射出成形装置から取り出した後、真空蒸着装置にセットして成膜し、しかる後、成膜した基材を真空蒸着装置から取り出した後、射出成形装置にセットして成膜面に樹脂材を射出成形することになって工程数も多く、手間がかかり、作業能率が悪いだけでなく、取り出し工程、セット工程、装置から装置への搬送工程の際に被成膜面、さらには成膜面に傷や埃がついたり手が触れて油が付着してしまうようなことがあり、これらが原因で所期の成膜製品ができず不良品が発生し歩留まりが悪いという問題がある。
そこで成形体を型成形するための型面が形成された第一金型、第二金型のうちの一方、例えば第二金型に成膜装置を設け、成形体を残した状態で型離れした第一金型を、成形体が成膜装置に対向するよう平行にスライド移動させ、しかる後、両金型を型合わせして成膜するようにしたものを提唱し、これによって成形体の成形と成膜とが一連の工程でできるようになり、作業性の改善、歩留まりの向上が達成できるようになった（例えば特許文献３）。
特開平６−１４７０６９号公報 特開平６−１６９１９１号公報 ＷＯ２００４／１０１２５３Ａ１ Generally, among these types of film-forming molded products, there are those whose design properties are improved by covering the surface of the member with a material having an effect such as a coloring effect or a reflection effect, such as parts such as an emblem for a vehicle. As this manufacturing method, for example, there is a method in which the surface of a member is formed by coating with a decorative chrome plating film (see, for example, Patent Document 1).
Nowadays, hexavalent chromium used for plating is a substance harmful to the human body, and since it causes pollution problems due to environmental pollution, it is subject to regulation and dechromation is required.
As an improvement measure, there is one in which a film is formed on a substrate surface by a film forming apparatus such as vacuum deposition or sputtering, and the surface of the film is covered with a resin material (for example, refer to Patent Document 2). .
However, in such a case, after the injection-molded base material is taken out from the injection molding apparatus, it is set in a vacuum vapor deposition apparatus to form a film, and then the film-formed base material is taken out from the vacuum vapor deposition apparatus and then injected. The number of processes is increased because it is set on the molding machine and injection molding of the resin material on the film forming surface is troublesome, and the work efficiency is not only poor, but also the removal process, the setting process, and the transport process from the equipment to the equipment At this time, the film-forming surface, as well as the film-forming surface, may be scratched, dusty, or touched and the oil may adhere to it. There is a problem that non-defective products are generated and the yield is poor.
Therefore, a film forming apparatus is provided on one of the first mold and the second mold on which the mold surface for molding the molded body is formed, for example, the second mold, and the mold is removed with the molded body remaining. The first mold was slid in parallel so that the molded body faced the film forming apparatus, and after that, the mold was formed by matching both molds. Molding and film formation can be performed in a series of steps, and workability and yield can be improved (for example, Patent Document 3).

次ぎに、本発明の第一の実施の形態について、図面に基づいて説明する。図中、１、２、３は第一、第二、第三の金型であって、該金型１、２、３を用いて成膜成形体４が成膜成型される。まず、第一金型１、第二金型２には未成膜の成形体４ａを型成形するための型面１ａ、２ａが形成され、第三金型３には成膜装置５が設けられている。本実施の形態では、第一金型１の型面１ａは凹形状、第二金型２の型面２ａは凸形状となっており、成膜装置５は第一金型１の型面１ａに対応する位置に設けられている。そして第一金型１は型圧を加える状態で離接方向（型表面と直交する方向）の移動（プレス移動）をし、第二金型２は離接方向と型面に沿う方向（型表面に沿う平行移動、型表面に直交する軸を軸芯とする回転移動の何れでも良い）との移動（例えば型合わせ方向の移動は復帰弾機６に抗する移動、型面に沿う移動はシリンダ７の伸縮による移動）とが自在にできるようになっている。また第三金型３は固定金型として本実施の形態では設定されている。さらに成膜装置５としては真空蒸着装置、スパッタリング成膜装置等、各種の成膜装置を適宜採用できることはいうまでもない。   Next, a first embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numerals 1, 2, and 3 denote first, second, and third molds, and the film-formed molded body 4 is formed into a film using the molds 1, 2, and 3. First, the first mold 1 and the second mold 2 are provided with mold surfaces 1a and 2a for molding an unformed film formed body 4a, and the third mold 3 is provided with a film forming apparatus 5. ing. In the present embodiment, the mold surface 1 a of the first mold 1 has a concave shape, the mold surface 2 a of the second mold 2 has a convex shape, and the film forming apparatus 5 has the mold surface 1 a of the first mold 1. Is provided at a position corresponding to. The first mold 1 moves (press moves) in the separation / contact direction (direction perpendicular to the mold surface) while applying the mold pressure, and the second mold 2 moves in the separation / contact direction and the direction along the mold surface (the mold). Any of parallel movement along the surface and rotational movement with the axis orthogonal to the mold surface as an axis may be used (for example, movement in the mold alignment direction is against movement of the return ammunition 6, and movement along the mold surface is And movement by expansion and contraction of the cylinder 7). The third mold 3 is set as a fixed mold in the present embodiment. Furthermore, it goes without saying that various film forming apparatuses such as a vacuum vapor deposition apparatus and a sputtering film forming apparatus can be appropriately employed as the film forming apparatus 5.

図１、２に、前記各金型１、２、３を用いて成膜４ａがなされた成形体４を形成する手順を示すが、まず、各金型１、２、３が型離れした状態（図１（Ａ）参照）から、第一金型１が第三金型３方向の移動をし、これによって第一、第二、第三金型１、２、３が順次積層状に型合わせされ、この状態で対向する型面１ａ、２ａ間に樹脂材が射出されて未成膜の成形体４が型成形される（図１（Ｂ）参照）。ついで第一金型１が型離れ方向に移動して各金型１、２、３が型離れするが、このとき未成膜成形体４は第一金型１側に残るように設計（例えばエジェクターピンによる積極的な抜きや型抜き角度の設定によって残る側を設定できる）されている（図１（Ｃ）参照）。このように型離れした後、第二金型２が型表面に沿う方向に移動して前記型合わせ領域から外れ（図２（Ａ）参照）、この外れた状態で第一金型１が型合わせ方向に移動をして第一、第三金型１、３が型合わせされて未成膜成形体４に成膜４ａがなされ、これによって成膜成形体４が形成される（図２（Ｂ）参照）。しかる後、第一成形体１が型離れ方向に移動し、成膜成形体４の取り出し（図２（Ｃ）参照）、第二金型２の型合わせ領域への復帰がなされ、この工程を繰返すことで成膜成形体４の一連の成形ができるようになっている。因みに、第三金型３は、成形体４の周面をマスキングして成膜がなされないように設定されている（以下の実施の形態においても同じ）。 FIGS. 1 and 2 show a procedure for forming the molded body 4 on which the film 4a is formed using the molds 1, 2, and 3. First, the molds 1, 2, and 3 are separated from each other. (Refer to FIG. 1 (A)), the first mold 1 moves in the direction of the third mold 3 so that the first, second, and third molds 1, 2, and 3 are sequentially stacked. In this state, a resin material is injected between the mold surfaces 1a and 2a facing each other, and an unfilm-formed molded body 4 is molded (see FIG. 1B). Then, the first mold 1 moves in the mold separating direction and the molds 1, 2, and 3 are separated from each other. At this time, the non-film-formed molded body 4 is designed to remain on the first mold 1 side (for example, an ejector). The remaining side can be set by aggressive punching with a pin or setting the die-cutting angle) (see FIG. 1C). After leaving the mold in this way, the second mold 2 moves in the direction along the mold surface and comes out of the mold matching area (see FIG. 2 (A)), and in this detached state, the first mold 1 is molded. The first and third molds 1 and 3 are moved together in the alignment direction to form a film 4a on the non-film-formed molded body 4, thereby forming the film-formed molded body 4 (FIG. 2B )reference). Thereafter, the first molded body 1 moves in the mold separation direction, the film-formed molded body 4 is taken out (see FIG. 2C), and the second mold 2 is returned to the mold alignment region. By repeating, a series of shaping | molding of the film-forming molded object 4 can be performed now. Incidentally, the 3rd metal mold | die 3 is set so that film-forming may not be made by masking the surrounding surface of the molded object 4 (the same also in the following embodiment).

叙述の如く構成された本発明の実施の形態において、成膜成形体４を一連の型移動の工程で形成できることになるが、この場合、型圧（プレス圧）を加える移動をする第一金型１は離接方向の移動だけを行い、成膜に必要な型表面に沿う方向の移動は第二金型２が行うことになり、この結果、従来の型合わせ方向に移動して型圧を加える金型に型表面に沿う方向の移動を行わせる場合のように構造が複雑化してしまうようなことを回避することができると共に、成膜成形体４が大型化しても装置全体が大型化してしまうことを回避できる。   In the embodiment of the present invention configured as described above, the film forming molded body 4 can be formed by a series of mold moving steps. In this case, the first metal moves to apply a mold pressure (pressing pressure). The mold 1 only moves in the separation / contact direction, and the second mold 2 moves in the direction along the mold surface necessary for film formation. It is possible to prevent the structure from becoming complicated as in the case of moving the mold in the direction along the mold surface, and the entire apparatus is large even if the film forming body 4 is enlarged. Can be avoided.

本発明は、さらに図３、４に示す第二の実施の形態としても実施することができる。このものは、第一、第二成形体８、９を一次の射出で型成形した後、第一成形体８に成膜８ａをし、しかる後、第一、第二成形体８、９を突き合わせて二次の射出で一体化するものであり、その成形工程について説明する。まず、第一、第二金型１０、１１には、第一、第二成形体８、９を型形成するための型面１０ａ、１１ａ、１０ｂ、１１ｂが形成されている一方、第三金型１２には成膜装置１３が設けられている。この場合において、前記第一の実施の形態と同様、第一金型８は型圧を付加すべく離接方向に移動し、第二金型１１は離接方向と型表面に沿う方向との移動が自在にできるようになっており、第三金型１２は固定金型である。そして成膜装置１３は第一金型１０の第一成形体８を成形するための型面１０ａと対向する位置に設けられている。 The present invention can also be implemented as a further second embodiment shown in FIGS. In this method, after the first and second molded bodies 8 and 9 are molded by primary injection, a film 8a is formed on the first molded body 8, and then the first and second molded bodies 8 and 9 are formed. These are combined and integrated by secondary injection, and the molding process will be described. First, the first and second molds 10 and 11 are formed with mold surfaces 10a, 11a, 10b and 11b for forming the first and second molded bodies 8 and 9, while the third mold The mold 12 is provided with a film forming apparatus 13. In this case, as in the first embodiment, the first mold 8 moves in the separation direction so as to apply a mold pressure, and the second mold 11 moves between the separation direction and the direction along the mold surface. The third mold 12 is a fixed mold. The film forming apparatus 13 is provided at a position facing the mold surface 10 a for molding the first molded body 8 of the first mold 10.

まず型離れ状態（図３（Ａ）参照）から第一金型１０が型合わせ方向に移動して順次積層状の型合わせがなされ（図３（Ｂ）参照）、この状態で第一、第二成形体８、９が射出により型成形（一次の射出成形）される。ついで第一金型１０が型離れ方向に移動して各金型１０、１１、１２が型離れ（図３（Ｃ）参照）する。このとき、第一成形体８が第一金型１０に残り、第二成形体９が第二金型１１に残るように設計されている。その後、第二金型１１が型合わせ領域から外れ（図４（Ａ）参照）、しかる後、第一金型１０が型合わせ方向に移動して第一、第三金型１０、１２が型合わせすることで第一成形体８と成膜装置１３とが対向し、成膜８ａが施される（図４（Ｂ）参照）。その後、第一金型１０の移動で型離れし、型合わせ領域に第二金型１１が移動してくるが、この移動は、第一成形体８と第二成形体９とが対向する移動であり（図４（Ｃ）参照）、この状態で第一金型１０が移動して順次積層状の型合わせがなされ、しかる後、樹脂材４ｂの二次の射出がなされて第一、第二成形体８、９が一体化され（図４（Ｄ）参照）、その後、型離れ、一体化された成膜成形体の取り出しがなされ、第二金型１１が第一、第二成形体８、９を型形成する前記位置に移動することを繰返すことで、内部が成膜された中空体やエンブレムのような成膜成形体を連続して成形することができると共に、成膜成形体が大型化しても装置全体が大型化してしまうことを回避できる。   First, the first mold 10 moves in the mold alignment direction from the mold separation state (see FIG. 3 (A)) to sequentially perform stacking mold alignment (see FIG. 3 (B)). The two molded bodies 8 and 9 are molded by injection (primary injection molding). Next, the first mold 10 moves in the mold separating direction, and the molds 10, 11, and 12 are separated (see FIG. 3C). At this time, it is designed so that the first molded body 8 remains in the first mold 10 and the second molded body 9 remains in the second mold 11. Thereafter, the second mold 11 is removed from the mold alignment region (see FIG. 4A), and then the first mold 10 is moved in the mold alignment direction and the first and third molds 10 and 12 are molded. By matching, the first molded body 8 and the film forming apparatus 13 face each other, and the film forming 8a is performed (see FIG. 4B). Thereafter, the mold is separated by the movement of the first mold 10, and the second mold 11 is moved to the mold-matching region. This movement is a movement in which the first molded body 8 and the second molded body 9 face each other. (Refer to FIG. 4C), and in this state, the first mold 10 is moved and the laminated molds are sequentially aligned, and then the secondary injection of the resin material 4b is performed and the first and second molds are made. The two molded bodies 8 and 9 are integrated (see FIG. 4D), then the mold is separated, and the integrated film-formed molded body is taken out, and the second mold 11 is the first and second molded bodies. By repeatedly moving to the position where the molds 8 and 9 are formed, a film-formed molded body such as a hollow body or an emblem in which the inside is formed can be continuously formed, and a film-formed molded body Even if the size of the apparatus increases, the entire apparatus can be prevented from increasing in size.

このように第二の実施の形態としたものも、型圧を付加する第一金型１０は型表面に沿う方向の移動を行う構成にする必要がなく、構成の簡略化が図れることになる。   In the second embodiment as described above, the first mold 10 to which the mold pressure is applied need not be configured to move in the direction along the mold surface, and the configuration can be simplified. .

さらに本発明は、図５、６に示す第三の実施の形態のようにすることもできる。このものは第一の実施の形態で形成されると同様の成膜成形体１４を第一、第二、第三金型１５、１６、１７を用いてより効率よく成形できるものである。型圧を付与する第一金型１５には凸形状の型面１５ａが形成され、第二金型１６には該型面１５ａに対応する型面が形成されるが、第二金型１６は、モータ等のアクチュエータ１８により、型表面と直交する軸１９を軸芯として１８０度づつ回転（回転は一方向回転であっても正逆回転であってもよい）できる設定となっていると共に復帰弾機２０に抗する状態で型合わせ方向に移動できるようになっている。そして第二金型１６が前記回転をすることで、第一金型１５に対向する型表裏面に型面１６ａ、１６ｂが形成されている。尚、第三金型１７は固定金型であって、型面１５ａに対向する位置に成膜装置２１が設けられている。因みに、第二金型１６の回転は、１８０度毎でなく、３６０度を偶数で除した角度、例えば９０度、６０度等の回転とすることもでき、このようにすることで、型面が形成される型表面を４面、６面と増やすことができることになる。 The present invention can also be as the third embodiment shown in FIGS. In this case, the same film-formed molded body 14 as that formed in the first embodiment can be molded more efficiently by using the first, second and third molds 15, 16 and 17. A convex mold surface 15a is formed on the first mold 15 for applying the mold pressure, and a mold surface corresponding to the mold surface 15a is formed on the second mold 16. The actuator 18 such as a motor is set so that it can be rotated 180 degrees about the axis 19 orthogonal to the mold surface (the rotation may be one-way rotation or forward / reverse rotation) and return. It can be moved in the mold matching direction against the ammunition 20. And the mold surfaces 16a and 16b are formed in the mold | die front and back facing the 1st metal mold | die 15 because the 2nd metal mold | die 16 rotates. The third mold 17 is a fixed mold, and a film forming apparatus 21 is provided at a position facing the mold surface 15a. Incidentally, the rotation of the second mold 16 can be performed at an angle obtained by dividing 360 degrees by an even number, for example, 90 degrees, 60 degrees, etc., instead of every 180 degrees. The surface of the mold on which is formed can be increased to 4 surfaces and 6 surfaces .

そしてこのものは、第二金型１６の一方の型面１６ａが第一金型１５の型面１５ａに対向する状態で第一金型１５が型合わせ方向に移動することで、互いに型離れしている（図５（Ａ）参照）第一、第二、第三金型１５、１６、１７の順次積層状の型合わせがなされ（図５（Ｂ）参照）、対向している型面１５ａ、１６ａ間に樹脂射出により未成膜の成形体１４が型成形される。次いで型離れした（図５（Ｃ）参照）後、第二金型１６が１８０度回転し（図５（Ｄ）参照）、型合わせされる（図６（Ａ）参照）。この状態では、前記成形された成形体１４が成膜装置２１に対向すると共に、第二金型１６の他方の型面１６ｂが第一金型１５の型面１５ａと対向することになって、成形体１４への成膜工程と射出による新たな成形体１４の成形工程とが実施される。その後、型離れして成膜１４ａが施された成形体１４の取り出し、並びに第二金型１６の１８０度回転がなされ（図６（Ｂ）（Ｃ）参照）た後、第一金型１５の型合わせをすること繰返すことで、成形体の型成形と成膜とが同時的に進行する成膜成形体の成形ができることになる。   This is because the first mold 15 moves in the mold alignment direction with the one mold surface 16a of the second mold 16 facing the mold surface 15a of the first mold 15, so that the molds are separated from each other. (See FIG. 5A) The first, second, and third molds 15, 16, and 17 are sequentially laminated (see FIG. 5B), and facing mold surfaces 15a. , 16a is molded into a non-film-formed molded body 14 by resin injection. Next, after the mold is released (see FIG. 5C), the second mold 16 is rotated 180 degrees (see FIG. 5D), and the mold is matched (see FIG. 6A). In this state, the molded body 14 is opposed to the film forming apparatus 21, and the other mold surface 16b of the second mold 16 is opposed to the mold surface 15a of the first mold 15. A film forming process on the molded body 14 and a molding process of a new molded body 14 by injection are performed. Thereafter, the molded body 14 on which the film formation 14a has been separated from the mold is taken out and the second mold 16 is rotated 180 degrees (see FIGS. 6B and 6C), and then the first mold 15 By repeating the mold matching, it is possible to mold the film-formed molded body in which the molding and film formation of the molded body proceed simultaneously.

このように実施することで、成膜成形体１４の成形をする場合に、型圧を付与する第一金型１５を型表面に沿う方向に移動させる必要がなくなって構成の簡略化ができると共に、第一、第二の実施の形態のように、成膜時、第二金型を型合わせ領域から外す必要がなく、型合わせ領域内に位置させたままでの成膜ができることになって装置の小型コンパクト化が果たせる。しかもこのものでは、成形体の型成形と成膜とが同時的に実行できることになって、効率の良い成膜成型品の製造ができると共に、成膜成形体が大型化しても装置全体が大型化してしまうことを回避できることになる。   By carrying out in this way, it is not necessary to move the first mold 15 for applying the mold pressure in the direction along the mold surface when molding the film-formed molded body 14, and the configuration can be simplified. As in the first and second embodiments, it is not necessary to remove the second mold from the mold matching area at the time of film formation, and the film can be formed while being positioned in the mold matching area. Can be made compact and compact. Moreover, in this case, the molding and film formation of the molded body can be performed simultaneously, so that an efficient film-forming molded product can be manufactured, and the entire apparatus is large even if the film-forming molded body is enlarged. It will be possible to avoid becoming.

尚、本発明を実施して成形される成膜成形体としては、車両用のサイドターンランプのような小型のものからバックランプやフロントランプのような大型のものまでの作成ができるが、このような成膜成形体としては、エンブレム、着色レンズ、ナンバープレートフレーム、耐食皮膜製品、化粧品のケース、グリル、磁気や電磁シールド製品、ミラー、ガーニッシュ、光学レンズ、車両用のインナーミラー、モール、耐摩耗性製品、ホイールキャップ、室内用照明器具（シャンデリアを含む）、リフレクター、ドアノブ等を例示することができる。   In addition, as a film-forming molded body formed by carrying out the present invention, it can be made from a small one such as a side turn lamp for a vehicle to a large one such as a back lamp or a front lamp. Examples of such film-forming molded products include emblems, colored lenses, license plate frames, corrosion-resistant coating products, cosmetic cases, grills, magnetic and electromagnetic shielding products, mirrors, garnishes, optical lenses, vehicle inner mirrors, moldings, Abrasive products, wheel caps, indoor lighting fixtures (including chandeliers), reflectors, door knobs and the like can be exemplified.
