Description

本発明は、第一、第二成形体を射出成形した後、第一成形体に成膜を形成し、これら第一、第二成形体を突き合わせた突き合わせ面に二次射出成形して一体化することで形成される射出成形体製造用の金型およびの射出成形体の製造方法の技術分野に属するものである。   In the present invention, after the first and second molded bodies are injection-molded, a film is formed on the first molded body, and secondary injection molding is performed on the butted surfaces where these first and second molded bodies are butted together. Thus, the present invention belongs to the technical field of a mold for producing an injection-molded body and a method for producing the injection-molded body.

一般に、この種射出成形体として車両用ランプがあるが、その一例であるサイドウインカーを射出成形する場合に、固定金型と該固定金型に対向し離接方向および対向面に平行する平行方向の相対移動をすることができる可動金型とで、ハウジング、レンズ部を各別に一次射出して成形し、それに続いて前記成形されたハウジングに成膜を形成し、そして該成膜済みのハウジングと前記レンズ部とを互いに突き合わせてその突き合わせ面に二次射出をして成形されるものがある。   In general, there is a vehicle lamp as this type of injection-molded body, but when injection molding a side blinker as an example, a fixed mold and a parallel direction opposite to the fixed mold and parallel to the contact direction and the facing surface And a movable mold that can move relative to each other, and a housing and a lens portion are molded by primary injection separately, followed by forming a film on the molded housing, and the film-formed housing And the lens portion are abutted against each other, and a secondary injection is performed on the abutting surface.

そして、このようなものの中には、固定金型と該固定金型と一対をなす可動金型で成形され、該固定金型の両端部にハウジング用の型面、レンズ部用の型面を備えこれらのあいだに成膜形成用の型面とを備えたものがある（例えば、特許文献１〜４参照。）。   Among these, a fixed mold and a movable mold paired with the fixed mold are molded, and a mold surface for the housing and a mold surface for the lens part are formed at both ends of the fixed mold. There are those provided with a mold surface for film formation (see, for example, Patent Documents 1 to 4).

しかしながらこれらのものは、可動金型が固定金型に対応してハウジング用の型面、レンズ部用の型面を両端に形成する必要があり、このため、可動金型が長くなって長くなった分、重量も重くなって相対移動させるための駆動装置の駆動力も大きなものを備える必要があった。
そこで、固定金型に一端側からレンズ部用の型面、ハウジング用の型面、成膜用の型面の順で形成することにより、可動金型に形成するハウジング用の型面、レンズ部用の型面とを隣接して形成することができるようにしたものがある（例えば、特許文献５〜７参照。）。
特開２００４−３３８３２８号公報 特許第３６８８２８９号公報 特許２００６−１６８１６０号公報 国際公開番号ＷＯ２００４／１０１２５３号公報 特開２００６−２３９９２５号公報 特開２００６−２４０００３号公報 特許２００６−２４０００４号公報 However, in these cases, it is necessary that the movable mold corresponds to the fixed mold, and the mold surface for the housing and the mold surface for the lens part must be formed at both ends. For this reason, the movable mold becomes long and long. For this reason, the driving force of the driving device for increasing the weight and making the relative movement has to be large.
Therefore, the mold surface for the lens, the mold surface for the housing, and the mold surface for film formation are formed in this order from one end to the fixed mold, thereby forming the mold surface for the housing and the lens portion that are formed on the movable mold There is one that can be formed adjacent to the mold surface (for example, see Patent Documents 5 to 7).
JP 2004-338328 A Japanese Patent No. 3688289 Japanese Patent No. 2006-168160 International Publication Number WO2004 / 101253 JP 2006-239925 A JP 2006-240003 A Japanese Patent No. 2006-240004

しかしながらこのものでは、固定金型のハウジング用の型面は凸型面であり、可動金型のレンズ部は凹型面であるため、成膜形成をする場合、これらの凸型面同士が対向することになり、これらの接触を避けるため、成膜成形用の型面は固定金型の他の型面よりも突出して高く形成されている。この結果、金型の構成が複雑になるといった問題がある。   However, in this case, the mold surface for the housing of the fixed mold is a convex surface, and the lens portion of the movable mold is a concave surface. Therefore, when forming a film, these convex surfaces face each other. Therefore, in order to avoid these contacts, the film surface for film forming is formed so as to protrude higher than the other surface of the fixed mold. As a result, there is a problem that the configuration of the mold becomes complicated.

しかもこのものでは一次射出する場合に、レンズ部およびハウジングの両方の射出圧に対応できる型締力に設定する必要があり、このため大きな型締力が必要であるといった問題があり、これらに本発明が解決しようとする課題がある。   Moreover, in this case, in the case of primary injection, it is necessary to set the mold clamping force to be compatible with the injection pressures of both the lens unit and the housing, and therefore there is a problem that a large mold clamping force is necessary. There is a problem to be solved by the invention.

The second primary injection molding is performed, and then the film formation for forming the film 5 for the reflective surface is performed on the housing 4, and then the housing 4 and the lens portion on which the film 5 is formed 7 is injected into the resin portion 6 and integrated to form the side blinker 1.

図２において、８は固定金型であり、該固定金型８には、図面視右側の一端に成膜５を成形するための成膜型面８ａが形成され、該成膜型面８ａから他端側に向かってハウジング４を成形するための成形用の凸型面８ｂ、レンズ部７を成形するための成形用の凹型面８ｃの順で隣接して形成されているが、成膜型面８ａは、凸型面８ｂ、凹型面８ｃと略同じ高さ（図面視上下方向）に位置している。また、成膜型面８ａには成膜手段９が収容されるが、本実施の形態の成膜手段９は、公知の真空蒸着装置であり、空気を抜き取って真空にするためのポンプＰと、該ポンプＰから成膜用型面８ａに至る吸気路１０と、蒸着する金属（例えば、アルミニウム、クロム）を入れるためのボート１１と、該ボート１１を熱してに前記金属を蒸発させるためのヒータ１２とを備えて構成されている。因みに、成膜手段９は、前記真空蒸着装置に限定されるものではなく、例えば、スパッタリング蒸着、化学蒸着法（ＣＶＤ）等、通常知られた各種の成膜装置を採用することができる。   In FIG. 2, reference numeral 8 denotes a fixed mold. The fixed mold 8 has a film forming mold surface 8 a for forming the film forming 5 at one end on the right side in the drawing, from the film forming mold surface 8 a. The convex mold surface 8b for molding the housing 4 toward the other end side and the concave mold surface 8c for molding the lens portion 7 are formed adjacent to each other in this order. The surface 8a is located at substantially the same height (vertical direction in the drawing) as the convex surface 8b and the concave surface 8c. Further, the film forming means 9 is accommodated in the film forming mold surface 8a. The film forming means 9 of the present embodiment is a known vacuum vapor deposition apparatus, and a pump P for extracting air to make a vacuum. , An intake passage 10 extending from the pump P to the film forming mold surface 8a, a boat 11 for containing a metal to be deposited (for example, aluminum or chromium), and for evaporating the metal by heating the boat 11 A heater 12 is provided. Incidentally, the film forming means 9 is not limited to the vacuum vapor deposition apparatus, and various commonly known film formation apparatuses such as sputtering vapor deposition and chemical vapor deposition (CVD) can be employed.

１３はハウジング４を形成するための凹型面１３ａが形成されたハウジング用金型であり、１４はレンズ部７を形成するための凸型面１４ａが形成されたレンズ部用金型である。前記ハウジング用金型１３、レンズ部用金型１４は、固定金型８に対向し各独立して固定金型８の離接方向、対向面に平行する平行方向（スライド方向）の相対移動ができるようになっている。   Reference numeral 13 denotes a housing mold in which a concave surface 13a for forming the housing 4 is formed. Reference numeral 14 denotes a lens portion mold in which a convex surface 14a for forming the lens portion 7 is formed. The housing mold 13 and the lens section mold 14 are opposed to the fixed mold 8 and can be moved independently in the direction of separation of the fixed mold 8 and in the parallel direction (sliding direction) parallel to the facing surface. It can be done.

そして、サイドウインカー１の成形方法を図２に基づいて説明する。
まず、図２（Ａ）に示すように、ハウジング用金型１３は、凹型面１３ａが固定金型８の凸型面８ｂに型合せされた状態で第一の一次射出成形がなされハウジング４を成形する。これに併せてレンズ部用金型１４は、凸型面１４ａが固定金型８の凹型面８ｃに型合せされた状態で第二の一次射出成形がなされレンズ部７を成形する。 And the shaping | molding method of the side blinker 1 is demonstrated based on FIG.
First, as shown in FIG. 2 (A), the housing mold 13 is subjected to first primary injection molding in a state where the concave mold surface 13a is aligned with the convex mold surface 8b of the fixed mold 8, and the housing 4 is formed. Mold. At the same time, the lens part mold 14 is molded by the second primary injection molding in a state where the convex mold surface 14 a is matched with the concave mold surface 8 c of the fixed mold 8 to mold the lens unit 7.

次いでハウジング用金型１３は、ハウジング４が残った状態で図２（Ａ）に破線で示したように相対移動し図２（Ｂ）に示す固定金型８の成膜型面８ａに型合せされハウジング４に成膜５が成膜形成される。またこれに併せてレンズ部用金型１４は、図２（Ａ）に一点鎖線で示すように相対移動し図２（Ｂ）に示す固定金型８と対向しない図面視右側に外れた状態になっている。
続いて、ハウジング用金型１３は、図２（Ｂ）の破線で示したように相対移動し第二の一次射出の後、固定金型８に残ったレンズ部７と突き合わされ二次射出成形がなされサイドウインカー１が製造される（図２（Ｃ）参照。）。 Next, the housing mold 13 moves relative to the film forming mold surface 8a of the fixed mold 8 shown in FIG. 2B by moving relatively as shown by the broken line in FIG. A film 5 is formed on the housing 4. At the same time, the lens part mold 14 is relatively moved as shown by a one-dot chain line in FIG. 2 (A) and is in a state of being disengaged on the right side in the drawing not facing the fixed mold 8 shown in FIG. 2 (B). It has become.
Subsequently, the housing mold 13 is relatively moved as shown by a broken line in FIG. 2B, and after the second primary injection, is abutted against the lens portion 7 remaining in the fixed mold 8 and is subjected to secondary injection molding. And the side blinker 1 is manufactured (see FIG. 2C).

そして、製造されたサイドウインカー1は、ハウジング用金型１３が固定金型８から離間した姿勢になった際に取り出され、ハウジング用金型１３は、凸型面８ｂに型合せされる姿勢に相対移動すると共に、レンズ部用金型１４は、ハウジング用金型１３の前記相対移動の後、凹型面８ｃに型合せされるように相対移動し以降、図２（Ａ）〜（Ｃ）が繰り返されサイドウインカー１が製造される。   The manufactured side blinker 1 is taken out when the housing mold 13 is separated from the fixed mold 8, and the housing mold 13 is aligned with the convex surface 8b. 2A to 2C, the lens part mold 14 moves relative to the concave mold surface 8c after the relative movement of the housing mold 13 and thereafter moves relative to each other. Repeatedly, the side blinker 1 is manufactured.

因みに、図２においては、ハウジング用金型１３、レンズ部用金型１４が同時に型合せされるように示したが、これに限られず金型１３、１４同士が衝突する等の弊害が無い限り、型合せを時間差で行っても良く、例えば、レンズ部用金型１４の第二の一次射出成形は、ハウジング用金型１３の二次射出成形後に凹型面８ｃから離間してから図２（Ｂ）のレンズ部７に突き合わされる姿勢になるまでのあいだに行うことができる。   Incidentally, in FIG. 2, the housing mold 13 and the lens mold 14 are shown to be aligned at the same time. However, the present invention is not limited to this, as long as there is no adverse effect such as the molds 13 and 14 colliding with each other. For example, the second primary injection molding of the lens mold 14 may be performed after the secondary injection molding of the housing mold 13 after being separated from the concave mold surface 8c. This can be done until the position of B) is brought into contact with the lens unit 7.

叙述の如く構成された本発明の実施の形態において、サイドウインカー１は、ハウジング４を第一の一次射出、レンズ部を第二の一次射出で成形した後、ハウジング４を成膜形成し、該成膜済みのハウジング４とレンズ部７とを突き合せて二次射出して製造されるが、該製造するにあたり、金型は、固定金型８に対して各独立して相対移動することができるハウジング用金型１３とレンズ部用金型１４とを備えた構成としており、これら金型１３、１４に掛かる射出圧は各独立して掛かるため、これら一体を同時に受ける従来の一体型のものよりも型締力の小さいものにすることができ、これによって小型の装置とすることができる。しかも、固定金型８は、成形型面８ａを、凸型面８ｂ、凹型面８ｃと略高さ（図面視上下方向）を同じ位置に形成することができるので、固定金型８の構成を容易なものとすることができる。   In the embodiment of the present invention configured as described, the side blinker 1 is formed by forming the housing 4 after forming the housing 4 by the first primary injection and the lens portion by the second primary injection, The film-formed housing 4 and the lens portion 7 are brought into contact with each other and manufactured by secondary injection. In the manufacture, the mold can move relative to the fixed mold 8 independently. The housing mold 13 and the lens section mold 14 are provided, and the injection pressure applied to the molds 13 and 14 is applied independently. Therefore, the mold clamping force can be made smaller than that, and thus a small apparatus can be obtained. Moreover, the fixed mold 8 can be formed with the molding surface 8a at the same position as the convex surface 8b and the concave surface 8c in the same height (vertical direction in the drawing). It can be easy.

尚、本発明は前記実施の形態に限定されるものでないことは勿論であり、例えば第一の実施の形態の固定金型８の型面８ａ、８ｂ、８ｃの配置を変換し、これに対応してハウジング用金型１３、レンズ部用金型１４の相対移動を適宜変更して実施することができる。   Needless to say, the present invention is not limited to the above-described embodiment. For example, the arrangement of the mold surfaces 8a, 8b, and 8c of the fixed mold 8 according to the first embodiment is converted to cope with this. Thus, the relative movement of the housing mold 13 and the lens section mold 14 can be changed as appropriate.
