Description

本発明は、車両に設置される車両用グリルに関する。   The present invention relates to a vehicle grill installed in a vehicle.

車両用グリルとしては、桟部が例えば格子状に設けられ、桟部間の開口より空気を取り込むようになっているものが知られている（特許文献１参照）。   As a grill for a vehicle, there is known a grille having a crosspiece provided in, for example, a lattice shape and taking in air from an opening between the crosspieces (see Patent Document 1).

かかる車両用グリルの一従来例が図５〜図８に示されている。図５〜図８において、車両用グリルであるフロントグリル（ラジエータグリル）５０は、合成樹脂材より射出成形によって形成される。フロントグリル５０は、略長方形状の枠体５１と、この枠体５１内の中心位置に配置されたセンタープレート部５２と、センタープレート部５２より枠体５１の上下部に向かって縦方向に延設されたセンター縦プレート部５３と、枠体５１内に間隔を置いて横方向に配置された複数の意匠桟部５４と、枠体５１内に間隔を置いて縦方向に配置された複数の補強桟部５５とを備えている。   One conventional example of such a vehicle grill is shown in FIGS. 5 to 8, a front grill (radiator grill) 50, which is a vehicle grill, is formed of a synthetic resin material by injection molding. The front grill 50 includes a substantially rectangular frame 51, a center plate portion 52 disposed at a central position in the frame 51, and extends vertically from the center plate portion 52 toward the upper and lower portions of the frame 51. The center vertical plate portion 53 provided, the plurality of design crosspieces 54 disposed in the frame body 51 at intervals, and the plurality of design crosspieces 54 disposed in the frame body 51 at intervals. And a reinforcing bar portion 55.

センタープレート部５２とセンター縦プレート部５３は、交差する各意匠桟部５４にそれぞれ連結されている。   The center plate portion 52 and the center vertical plate portion 53 are connected to the intersecting design crosspieces 54, respectively.

意匠桟部５４は、意匠本体部５４ａと、意匠本体部５４ａの下方位置より後方側に向かって延設されたフランジ部５４ｂとを有する。意匠桟部５４と補強桟部５５は、意匠本体部５４ａとフランジ部５４ｂの２箇所の位置で連結されている。意匠桟部５４と補強桟部５５は、射出成形時におけるスムーズな樹脂流の確保、成形後の変形防止の観点等よりほぼ同じ肉厚に形成されている。   The design crosspiece 54 includes a design main body portion 54a and a flange portion 54b extending toward the rear side from a lower position of the design main body portion 54a. The design crosspiece 54 and the reinforcement crosspiece 55 are connected at two positions of the design main body 54a and the flange 54b. The design crosspiece 54 and the reinforcement crosspiece 55 are formed to have substantially the same thickness from the viewpoint of ensuring a smooth resin flow during injection molding and preventing deformation after molding.

フロントグリル５０の射出成形にあっては、図５にゲート対応位置を示すように複数のゲートＧ１，Ｇ２より金型のキャビティ内に溶融樹脂が注入される。センターゲートＧ１より注入された溶融樹脂は、センタープレート部５２より直接に、若しくは、センタープレート部５２よりセンター縦プレート部５３を介して各意匠桟部５４に流れ込む。この各意匠桟部５４に流れ込んだ樹脂流が各意匠桟部５４を進み、各意匠桟部５４に樹脂が充填されるとともに連結されている各補強桟部５５に流れ込む。また、各枠体側ゲートＧ２より注入された溶融樹脂は、枠体５１より各補強桟部５５に流れ込む。この各補強桟部５５に流れ込んだ樹脂流が各補強桟部５５を進み、各補強桟部５５に樹脂が充填される。   In the injection molding of the front grill 50, molten resin is injected into the mold cavity from the plurality of gates G1 and G2, as shown in FIG. The molten resin injected from the center gate G1 flows into the design crosspieces 54 directly from the center plate portion 52 or from the center plate portion 52 via the center vertical plate portion 53. The resin flow that has flowed into the design crosspieces 54 travels through the design crosspieces 54, fills the design crosspieces 54 with resin, and flows into the connected reinforcement crosspieces 55. In addition, the molten resin injected from each frame body side gate G <b> 2 flows from the frame body 51 into each reinforcing bar 55. The resin flow that has flowed into the reinforcing bars 55 travels through the reinforcing bars 55, and the reinforcing bars 55 are filled with resin.

しかしながら、前記従来例の車両用グリルであるフロントグリル５０では、意匠桟部５４と補強桟部５５の各連結箇所は、他の箇所と同じ肉厚で連結されているため、溶融樹脂が意匠桟部５４と補強桟部５５間を容易に流出入可能である。そのため、補強桟部５５を流れる溶融樹脂が連結箇所を介して意匠桟部５４に容易に回り込むことができる。このような回り込み流が意匠桟部５４に発生すると意匠桟部５４を複数の樹脂流が流れることになり、樹脂流の合流部にウエルドラインが発生する。意匠桟部５４にウエルドラインが発生すると、機械的特性の低下や外観品質の不良等の原因となる。特に、ウエルドラインが意匠本体部５４ａの表面に出来ると、外観品質の観点より非常に問題である。   However, in the front grill 50 which is a vehicle grill according to the conventional example, the connecting portions of the design crosspiece 54 and the reinforcing crosspiece 55 are connected with the same thickness as other portions, so that the molten resin is used as the design crosspiece. It is possible to easily flow in and out between the portion 54 and the reinforcing bar portion 55. Therefore, the molten resin flowing through the reinforcing crosspiece 55 can easily go around the design crosspiece 54 via the connecting portion. When such a sneak flow is generated in the design crosspiece 54, a plurality of resin flows flow through the design crosspiece 54, and a weld line is generated in the junction of the resin flow. If a weld line is generated in the design crosspiece 54, it may cause deterioration of mechanical characteristics, poor appearance quality, and the like. In particular, if a weld line can be formed on the surface of the design main body 54a, this is very problematic from the viewpoint of appearance quality.

そこで、本発明は、前記した課題を解決すべくなされたものであり、意匠桟部にウエルドラインが発生するのを極力防止できる車両用グリルを提供することを目的とする。   Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle grill that can prevent the occurrence of a weld line at a design crosspiece as much as possible.

図１〜図４に示すように、車両用グリルであるフロントグリル１は、アクリロニトリル−ブタジエン−スチレン共重合体（ＡＢＳ）等の合成樹脂材より射出成形によって形成されている。   As shown in FIGS. 1 to 4, a front grill 1 that is a vehicle grill is formed by injection molding from a synthetic resin material such as acrylonitrile-butadiene-styrene copolymer (ABS).

フロントグリル１は、略長方形状の枠体２と、この枠体２内の中心位置に配置されたセンタープレート部３と、センタープレート部３より枠体２の上下部に向かって縦方向に延設されたセンター縦プレート部４と、枠体２内に間隔を置いて横方向に配置された複数の第１桟部である意匠桟部１０と、枠体２内に間隔を置いて縦方向に配置された複数の第２桟部である補強桟部２０とを備えている。   The front grill 1 includes a substantially rectangular frame 2, a center plate portion 3 disposed at the center of the frame 2, and a vertical extension from the center plate portion 3 toward the upper and lower portions of the frame 2. The center vertical plate portion 4 provided, the design crosspiece 10 which is a plurality of first crosspieces arranged in the horizontal direction at intervals in the frame 2, and the vertical direction at intervals in the frame 2 And reinforcing bar portions 20 as a plurality of second bar portions arranged at the same position.

センタープレート部３とセンター縦プレート部４は、交差する各意匠桟部１０にそれぞれ連結されている。   The center plate portion 3 and the center vertical plate portion 4 are respectively connected to the intersecting design crosspieces 10.

意匠桟部１０は、前方に向かって下方に傾斜しつつ突出する意匠本体部１１と、意匠本体部１１の下方位置より後方側に向かって延設されたフランジ部１２とを有する。意匠本体部１１の前面は、前方より視認することができる意匠面である。   The design crosspiece 10 includes a design main body 11 that protrudes while tilting downward toward the front, and a flange 12 that extends from the lower position of the design main body 11 toward the rear side. The front surface of the design main body 11 is a design surface that can be viewed from the front.

各補強桟部２０は、各意匠桟部１０の意匠本体部１１とフランジ部１２の２箇所の位置で交差し、この２箇所の位置で連結されている。従って、補強桟部２０は、枠体２と意匠桟部１０の間や隣り合う意匠桟部１０間を連結する桟間部２１と、意匠桟部１０の意匠本体部１１とフランジ部１２間を連結する桟内部２２とが交互に配置されて構成される。   Each reinforcing crosspiece 20 intersects at two positions of the design main body portion 11 and the flange portion 12 of each design crosspiece portion 10 and is connected at these two positions. Accordingly, the reinforcing crosspiece 20 includes a crosspiece 21 that connects the frame 2 and the design crosspiece 10 or between the adjacent design crosspieces 10, and between the design main body 11 and the flange portion 12 of the design crosspiece 10. The crosspiece interiors 22 to be connected are alternately arranged.

意匠桟部１０と補強桟部２０は、射出成形時におけるスムーズな樹脂流の確保、成形後の変形防止の観点等よりほぼ同じ肉厚に形成されるが、意匠桟部１０と補強桟部２０の連結箇所の一部は薄肉部１２ａ，２２ａに形成されている。具体的には、意匠桟部１０は、そのフランジ部１２の少なくとも連結箇所が他の箇所よりも薄肉のフランジ薄肉部１２ａとして形成されている。本実施形態においては、フランジ部１２の先端に全長に亘ってフランジ薄肉部１２ａが形成されている。又、補強桟部２０は、意匠本体部１１とフランジ部１２の間に位置する箇所（桟内部２２）で、且つ、意匠本体部１１との連結箇所が他の箇所よりも薄肉の桟薄肉部２２ａとして形成されている。   The design crosspiece 10 and the reinforcement crosspiece 20 are formed to have substantially the same thickness from the viewpoint of ensuring a smooth resin flow during injection molding and preventing deformation after molding. A part of the connecting portion is formed in the thin portions 12a and 22a. Specifically, the design crosspiece 10 is formed as a flange thin portion 12a in which at least a connection portion of the flange portion 12 is thinner than other portions. In this embodiment, the flange thin part 12a is formed in the front-end | tip of the flange part 12 over the full length. Moreover, the reinforcement crosspiece 20 is a location (crosspiece interior 22) located between the design main body portion 11 and the flange portion 12, and the connection portion with the design main body portion 11 is thinner than the other locations. 22a is formed.

フロントグリル１の表面には、図示しないがメッキや塗装等の表面処理が施されている。   Although not shown, the surface of the front grill 1 is subjected to a surface treatment such as plating or painting.

上記構成のフロントグリル１の射出成形にあっては、図１にゲート対応位置を示すように複数のゲートＧ１，Ｇ２より金型のキャビティ内に溶融樹脂が注入される。センターゲートＧ１より注入された溶融樹脂は、センタープレート部３より直接に、若しくは、センタープレート部３よりセンター縦プレート部４を介して各意匠桟部１０に流れ込む。この各意匠桟部１０に流れ込んだ樹脂流が各意匠桟部１０を進み、各意匠桟部１０に樹脂が充填されるとともに連結されている各補強桟部２０に流れ込む。また、各枠体側ゲートＧ２より注入された溶融樹脂は、枠体２より各補強桟部２０に流れ込む。この各補強桟部２０に流れ込んだ樹脂流が各補強桟部２０を進み、各補強桟部２０に樹脂が充填される。   In the injection molding of the front grill 1 having the above-described configuration, molten resin is injected into the mold cavity from the plurality of gates G1 and G2, as shown in FIG. The molten resin injected from the center gate G1 flows into the design crosspieces 10 directly from the center plate portion 3 or from the center plate portion 3 through the center vertical plate portion 4. The resin flow that has flowed into each design crosspiece 10 travels through each design crosspiece 10 and fills each design crosspiece 10 with resin and flows into each reinforcing crosspiece 20 that is connected. Further, the molten resin injected from each frame body side gate G <b> 2 flows from the frame body 2 into each reinforcing bar 20. The resin flow that has flowed into the reinforcing bars 20 travels through the reinforcing bars 20, and the reinforcing bars 20 are filled with resin.

ここで、補強桟部２０に流れる溶融樹脂は、フランジ薄肉部１２ａ及び桟薄肉部２２ａによって意匠桟部１０への流入が制限される。そのため、補強桟部２０を流れる溶融樹脂は補強桟部２０を極力流れようとし、補強桟部２０から意匠桟部１０への樹脂流の回り込みが極力防止されるため、意匠桟部１０には一定方向の溶融樹脂の流れによって樹脂が極力充填される。従って、意匠桟部１０にウエルドラインが発生するのを極力防止できる。又、意匠桟部１０の意匠本体部１１の下方位置より後方側に向かって延設されたフランジ部１２の先端に全長に亘ってフランジ薄肉部１２ａが形成されており、意匠桟部１０に流れる溶融樹脂は、意匠本体部１１及びフランジ部１２と、フランジ薄肉部１２ａとで肉厚が異なるため樹脂流速度に差異が生じ、意匠本体部１１及びフランジ部１２を極力流れようとする。従って、少なくともフロントグリル1の表面である意匠本体部１１にウエルドラインが発生するのを極力防止できる。   Here, the molten resin flowing to the reinforcing bar 20 is restricted from flowing into the design bar 10 by the flange thin part 12a and the bar thin part 22a. Therefore, the molten resin flowing through the reinforcing bar 20 tries to flow through the reinforcing bar 20 as much as possible, and the resin flow from the reinforcing bar 20 to the design bar 10 is prevented as much as possible. The resin is filled as much as possible by the flow of molten resin in the direction. Therefore, it is possible to prevent the weld line from occurring in the design crosspiece 10 as much as possible. Further, a flange thin portion 12 a is formed over the entire length at the front end of the flange portion 12 extending from the lower position of the design main body portion 11 of the design crosspiece portion 10 toward the rear side, and flows to the design crosspiece portion 10. Since the thickness of the molten resin differs between the design main body 11 and the flange portion 12 and the flange thin portion 12a, the resin flow speed is different, and the molten resin tends to flow through the design main body portion 11 and the flange portion 12 as much as possible. Therefore, it is possible to prevent the occurrence of a weld line at least in the design main body 11 which is the surface of the front grill 1 as much as possible.

意匠桟部１０は、意匠本体部１１と意匠本体部１１の下方位置より後方側に向かって延設されたフランジ部１２を有し、意匠桟部１０と補強桟部２０は、意匠本体部１１とフランジ部１２の２箇所の位置で連結されている。従って、各意匠桟部１０の２箇所で各補強桟部２０が連結されるため、ウエルドラインの発生を極力防止しつつ意匠桟部１０を補強桟部２０で強固に補強できる。   The design crosspiece 10 includes a design main body 11 and a flange 12 that extends from the lower position of the design main body 11 toward the rear side, and the design crosspiece 10 and the reinforcing crosspiece 20 include the design main body 11. And the flange portion 12 are connected at two positions. Therefore, since each reinforcement crosspiece 20 is connected in two places of each design crosspiece 10, the design crosspiece 10 can be firmly reinforced with the reinforcement crosspiece 20 while preventing the occurrence of a weld line as much as possible.

薄肉部１２ａ，２２ａは、意匠桟部１０のフランジ部１２の連結箇所に設けられたフランジ薄肉部１２ａと、補強桟部２０の意匠本体部１１とフランジ部１２の間（桟内部２２）で、且つ、意匠本体部１１との連結箇所に設けられた桟薄肉部２２ａである。従って、意匠桟部１０の意匠本体部１１を薄肉にしないため、ウエルドラインの発生を極力防止しつつ意匠桟部１０の意匠本体部１１の強度を維持できる。又、隣り合う意匠桟部１０の間に位置する補強桟部２０の箇所（桟間部２１）を薄肉にしないため、ウエルドラインの発生を極力防止しつつ補強桟部２０の補強機能を維持できる。   The thin portions 12a and 22a are between the flange thin portion 12a provided at the connecting portion of the flange portion 12 of the design crosspiece 10 and the design main body portion 11 and the flange portion 12 of the reinforcement crosspiece 20 (inside the crosspiece 22). And it is the crosspiece | thin wall part 22a provided in the connection location with the design main-body part 11. FIG. Therefore, since the design main body 11 of the design crosspiece 10 is not thinned, the strength of the design main body 11 of the design crosspiece 10 can be maintained while preventing the generation of weld lines as much as possible. In addition, since the portion of the reinforcing bar 20 (between the bars 21) located between the adjacent design bars 10 is not thinned, the reinforcing function of the reinforcing bar 20 can be maintained while preventing the generation of weld lines as much as possible. .
