Description

【発明の属する技術分野】
本発明は、合成樹脂製の模様付き蓋状体をインサート成形により成形する方法と該成形方法で使用する金型に関する。
【従来の技術】
頂板の上面へ、シート材をインサート成形した蓋体、該蓋体の成形方法、および該蓋体成形に使用する金型が特許文献１に示されている。

特開２００２−２８３３８５号公報
【発明が解決しようとする課題】
透明蓋体の頂板下面へ模様を付設すれば、外観上その模様は透明な頂板を介して目視されることとなるため、頂板上面に付した模様と異って深みのある模様とすることが出来、又頂板下面へ他物が接することは少ないから、頂板上面へ付設した模様の場合と異り、摩擦等により模様が薄れたり、剥離するおそれがない。
よって透明蓋体の頂板下面への模様の付設が要望されるが、蓋体周壁が邪魔となるため、その頂板下面への印刷は困難であり、インサート成形することが考えられる。該頂板下面へのインサート成形を、頂板の上面形成用金型面の中央にゲートを設けて、該ゲートからキャビティ内への樹脂材料射出によって行えば、頂板の下面形成用金型部分の上面へ付着させたインサート成形用フィルムは樹脂材料射出によって下方へ押付けられて移動等することがなく、好都合ではあるが、このようにすると成品としての蓋体頂板の中央部にゲート跡が残り、外見上好ましくない。よってゲートは頂板外周面の一部ないし周壁外面の上端部へ設けることとなるが、このようにすると頂板下面形成用金型部分上面へ付着させた、上記インサート成形用フィルムが横ずれを生じ易い。
本発明は上記欠点を除去することを目的とした成形方法および該成形方法で使用する金型に関する。尚本発明において透明とは、半透明も含むものとする。又本発明において蓋状体とは、頂板外周から周壁を垂下する蓋体の他、頂板外周から周壁を垂下する台等を含むものとする。

上記頂板２の下面形成用上面１３と、周壁３の内周面形成用外周面１４とを有する凸状金型部分１６を可動金型１２に設け、上記ゲート７と対向する、凸状金型部分上面の外縁部から、上記凸状金型部分１６の上面へ載置されてインサートされる、模様付きフィルム１９のゲート側端面当接用のフランジ２１を起立させた。

【発明の実施の形態】
以下図面について説明すると、１は、図６、図８が示すような、頂板２外周から周壁３を垂下し、該周壁の左右両側壁３ａ後端から軸受板４，４を垂下し、これ等軸受板の各下端部に軸受孔５，５を穿設した蓋体６形成用のキャビティで、該キャビティを固定金型１１と可動金型１２との間に形成している。該キャビティは、外周面の上方一部、具体的には上記周壁の後壁３ｂ上部の左右方向中間上部の後面、ないしは頂板後面の左右方向中間下部にゲート７を有する。上記蓋体を、頂板外周から周壁を垂下するだけの台とする場合は、軸受板４、４を省略する。
又可動金型１１は、上記頂板の下面形成面としての上面１３と、周壁３の内周面形成面としての外周面１４とを有し、かつ上記上面１３へ、バキューム通路１５を開口する凸状金型部分１６を有する。そのバキューム通路１５は、図示のように上記凸状金型部分の中央部上部をコア金型１６ａ で形成し、該コア金型の下面および外周面へ穿設した溝で形成すればよい。
上記凸状金型部分１６上面で、ゲート７と対向する外縁側からはフランジ２１を起立させており、該フランジ内面へ当接させて、上記上面１３へ図５が示す、模様１８付きフィルム１９を吸着させている。
図１が示す状態から、キャビティ１内へ溶融樹脂材料２０を射出すると、ゲート７からキャビティ１内へ射出された溶融樹脂材料は、キャビティの周壁形成部分および頂板形成部分内へ入るが、ゲート７と対向する、上記フィルム１９の端面部分は、該ゲートと対向するフランジ２１部分の内面へ当接しているから、ゲート７から射出された溶融樹脂材料がフィルムの端面を押圧することはなく、フィルム１９上面を下方へ押圧することとなり、よってフィルム１９がフランジ２１内面から外方へずれることはなく、このようにしてフィルム１９を頂板２下面の所定位置へ正確にインサート成形することが可能となる。
尚上記フランジ２１は、図３が示すように、ゲート７側と対向する、凸状金型部分上面の外縁、つまり図示例では蓋体周壁の前壁形成側の凸状金型上面外周部からだけ起立させてもよく、又図４が示すように凸状金型部分上面の全周から起立させてもよい。
図３の場合は、ゲート７から射出された溶融樹脂材料が、フィルム１９を図左方へ押圧することとなるが、該フィルムは図左方に設けたフランジ２１内面へ接しているため、左方へ位置ずれすることはない。
それ等いずれの場合も上記フィルム１９は、フランジ内面へフィルム１９外周面の一部ないし全周を当接させて凸状金型部分上面へ吸着させる。
凸状金型部分１６上面への模様付きフィルム１９の付設は、バキューム通路での吸着のほか、例えば接着剤使用等による付着も考えられる。
既述各実施形態のようにして、インサート成形が終わった後に、金型を開き、蓋状体６としての成形品を取出す。
第１実施形態により成形された蓋状体は、ゲート跡２４側の頂板内面の外縁と、該外縁部から垂下する側壁内面上端とが形成する隅部分から下面開口の浅溝が起立することとなり、第２実施形態の場合は、ゲート跡２４側と対向する頂板部分内面の外縁と該外縁から垂下する側壁内面とが形成する隅部分から下面開口の浅溝が起立することとなり、第３実施形態の場合は、図６、図７が示すように頂板２の下面外周と周壁３内面上端とが形成する隅部全周から既述フランジ抜け跡としての下面開口浅溝２３が形成されることとなる。
尚既述模様付きフィルム１９は、転写フィルムとしてもよく、この場合は蓋状体形成後に、転写後のフィルムだけ、頂板２下面から剥離し、模様１８は頂板２下面へ転写させることとなる。
【発明の効果】
本発明は既述構成とするもので、請求項１から請求項４記載のようにすることで、模様付きフィルム１９を蓋状体頂板２の下面の所定位置へ正確にインサート成形することが出来、その模様１８は蓋状体頂板２の下面へ付設されることとなるため、頂板上面へ付設された模様と異り、頂板を透視してその模様を見ることとなるため深みのある模様となって見えることとなり、このように深みのある模様付きの透明ないし半透明蓋状体の成形を容易に行うことが出来る。又このように成形された蓋状体は頂板上面へ付設した模様の場合と異り、摩擦等により模様が薄れたり、剥離するおそれがない。
又請求項５から請求項８記載の金型を使用して成形することで、上記請求項１から請求項４記載の蓋状体の成形を容易に行うことが出来る。

JP, 2002-283385, A [Problems to be solved by the invention]
If a pattern is attached to the lower surface of the top plate of the transparent lid, the pattern will be visible through the transparent top plate in appearance, so it may be a deeper pattern unlike the pattern attached to the upper surface of the top plate. Since there is little possibility that other objects come into contact with the lower surface of the top plate, unlike the case where the pattern is provided on the upper surface of the top plate, there is no possibility that the pattern is thinned or peeled off due to friction or the like.
Therefore, it is desired to attach a pattern to the lower surface of the top plate of the transparent lid, but it is difficult to print on the lower surface of the top plate because the peripheral wall of the lid interferes, and insert molding may be considered. If insert molding to the lower surface of the top plate is performed by providing a gate at the center of the upper surface forming die surface of the top plate and injecting a resin material into the cavity from the gate, the upper surface of the lower surface forming die portion of the top plate can be formed. The attached insert molding film is not pressed down by the injection of the resin material and does not move, which is convenient. However, in this case, a gate mark remains at the center of the top plate of the lid as a product, and the appearance is apparent. Not preferred. Therefore, the gate is provided at a part of the outer peripheral surface of the top plate or at the upper end of the outer surface of the peripheral wall. In this case, the insert molding film adhered to the upper surface of the die for forming the lower surface of the top plate is liable to laterally shift.

BEST MODE FOR CARRYING OUT THE INVENTION
Referring to the drawings, reference numeral 1 indicates that, as shown in FIGS. 6 and 8, the peripheral wall 3 hangs from the outer periphery of the top plate 2 and the bearing plates 4, 4 hang from the rear ends of the left and right side walls 3a of the peripheral wall. A cavity for forming the lid 6 having bearing holes 5 and 5 formed at the lower end of the bearing plate. The cavity is formed between the fixed mold 11 and the movable mold 12. The cavity has a gate 7 at an upper part of the outer peripheral surface, specifically, at a rear upper part in the left-right direction above the rear wall 3b of the peripheral wall, or at a lower part in the left-right direction at the rear surface of the top plate. In the case where the lid is a base that only hangs the peripheral wall from the outer periphery of the top plate, the bearing plates 4 and 4 are omitted.
Further, the movable mold 11 has an upper surface 13 as a lower surface forming surface of the top plate and an outer peripheral surface 14 as an inner peripheral surface forming surface of the peripheral wall 3, and has a convex opening that opens a vacuum passage 15 to the upper surface 13. It has a mold part 16. As shown in the figure, the vacuum passage 15 may be formed by forming a central upper portion of the above-mentioned convex mold portion with a core mold 16a and forming grooves formed on the lower surface and the outer peripheral surface of the core mold.
On the upper surface of the convex mold portion 16, a flange 21 is erected from the outer edge side facing the gate 7. The flange 21 is brought into contact with the inner surface of the flange, and the film 19 with the pattern 18 shown in FIG. Is adsorbed.
When the molten resin material 20 is injected into the cavity 1 from the state shown in FIG. 1, the molten resin material injected into the cavity 1 from the gate 7 enters the peripheral wall forming portion and the top plate forming portion of the cavity. The end face portion of the film 19, which faces the gate, is in contact with the inner surface of the flange 21 portion facing the gate, so that the molten resin material injected from the gate 7 does not press the end face of the film. The upper surface 19 is pressed downward, so that the film 19 does not shift outward from the inner surface of the flange 21. In this way, it is possible to insert-mold the film 19 accurately at a predetermined position on the lower surface of the top plate 2. .
The flange 21 is, as shown in FIG. 3, from the outer edge of the upper surface of the convex mold portion facing the gate 7 side, that is, from the outer peripheral portion of the upper surface of the convex mold on the front wall forming side of the lid peripheral wall in the illustrated example. Only, or as shown in FIG. 4, it may be raised from the entire circumference of the upper surface of the convex mold portion.
In the case of FIG. 3, the molten resin material injected from the gate 7 presses the film 19 to the left in the figure, but since the film is in contact with the inner surface of the flange 21 provided on the left in the figure, the left There is no misalignment.
In any of these cases, the film 19 is adsorbed to the upper surface of the convex mold by bringing a part or the entire periphery of the outer surface of the film 19 into contact with the inner surface of the flange.
The attachment of the patterned film 19 to the upper surface of the convex mold portion 16 may be caused by, for example, using an adhesive or the like in addition to suction in the vacuum passage.
After the insert molding is completed as in the above-described embodiments, the mold is opened and the molded product as the lid 6 is taken out.
In the lid-like body formed according to the first embodiment, a shallow groove with a lower surface opening rises from a corner formed by the outer edge of the inner surface of the top plate on the gate mark 24 side and the upper end of the inner surface of the side wall hanging from the outer edge. In the case of the second embodiment, the shallow groove of the lower surface opening rises from the corner formed by the outer edge of the inner surface of the top plate portion facing the gate mark 24 side and the inner surface of the side wall hanging down from the outer edge. In the case of the form, as shown in FIGS. 6 and 7, the lower surface opening shallow groove 23 as the trace of the above-mentioned flange escape is formed from the entire periphery of the corner formed by the outer periphery of the lower surface of the top plate 2 and the upper end of the inner surface of the peripheral wall 3. It becomes.
The patterned film 19 may be a transfer film. In this case, after forming the lid, only the transferred film is peeled off from the lower surface of the top plate 2, and the pattern 18 is transferred to the lower surface of the top plate 2.
【The invention's effect】
The present invention has the above-described configuration, and by performing the method described in claims 1 to 4, the patterned film 19 can be accurately insert-molded at a predetermined position on the lower surface of the lid-like top plate 2. Since the pattern 18 is provided on the lower surface of the lid-like body top plate 2, unlike the pattern provided on the upper surface of the top plate, the pattern 18 is seen through the top plate and the pattern is deeper. This makes it possible to easily form a transparent or translucent lid with a deep pattern. In addition, unlike the case of the pattern attached to the top surface of the top plate, the lid-shaped body thus formed does not have a risk of the pattern becoming thin or peeling due to friction or the like.
Further, by molding using the mold according to claims 5 to 8, the lid-like body according to claims 1 to 4 can be easily molded.
