３等はその鋳型例であって、従来から様々な意匠が施さ
れてきた。Depending on the field of use, blow molded products may be required to have an aesthetic appearance. Containers for cosmetics, detergents, etc., and vehicular devices 3 are examples of such molds, and various designs have been applied heretofore.
従来、この様な加飾された中空成形品を得るには彫刻、
エツチング等によって模様類を刻み付けた中空成形用金

のほかに二次加工で表面に布を接着する方法等がとられ
てきた。Conventionally, to obtain such decorated hollow molded products, engraving,
It is common to blow-mold resin using a blow-molding mold with a pattern engraved by etching or the like, and other methods have also been used, such as gluing cloth to the surface as a secondary process.
しかし、前者の方法は金型製作費が高くつき、少量多品
種の分野には適さないという問題点があり、一方、後者
の方法にも皺がなく美しく貼るには熟練が要り、且つ剥
がれやすいという問題点があった。However, the former method has the problem of high mold production costs and is not suitable for low-volume, high-mix production.On the other hand, the latter method also requires skill to apply beautifully without wrinkles, and is easy to peel off. There was a problem.
本発明はこれらの問題点を解決し、簡便で故障のない方
法で、外面に装飾布が固着された布付中空射出成形品を
提供するものである。The present invention solves these problems and provides a cloth-covered hollow injection molded product having a decorative cloth fixed to its outer surface using a simple and trouble-free method.
本発明者は上記の目的を達成するため中空成形における
一体成形の技術を検討した結果、布を中突成形と同時に
その表面に固着する技術を開発し、本発明を完成した。In order to achieve the above object, the present inventor investigated the technology of integral molding in blow molding, and as a result, developed a technology for fixing the cloth to the surface at the same time as the hollow molding, and completed the present invention.
すなわち本発明は、金型内に配設された布を中空成形と
同時に成形体表面に固着けしめてなる布付中空成形品を
提供するものであり、又これを製造する方法として、布

を中空成形することを特徴とする布付中空成形品の製造
方法を提供するものである。That is, the present invention provides a cloth-attached hollow molded product in which a cloth disposed in a mold is fixed to the surface of the molded product at the same time as blow molding, and as a method for manufacturing this, the cloth is formed into a parison. The present invention provides a method for producing a cloth-covered hollow molded article, which comprises stretching a synthetic resin in a mold so as to cover the cloth, and then blow molding the synthetic resin.
以下本発明の詳細な説明する。The present invention will be explained in detail below.
本発明の加飾中空成形品を製造するには、まず、成形品
の表面を飾るべき模様、表面形状、凹凸及び印刷等を有
する布を用意しなければならない。In order to manufacture the decorated hollow molded article of the present invention, it is first necessary to prepare a cloth having a pattern, surface shape, irregularities, printing, etc. to decorate the surface of the molded article.
これらの布には比較的目の粗い意匠を施された布、例え
ば装飾、加飾、意匠のあるレース、テープ、アップリケ
、メツシュ等や、比較的目の細かい織目又は編目のある
布及びこれらの組み合わせが用いられるが、より好まし
くは伸縮性又は弾性のある布である。尚、これらの布は
筒状にしておきパリソンを覆ってもよい。また布にあら
かじめ粘、接着剤を塗布しておいてもよい。These fabrics include fabrics with relatively coarse designs, such as decorations, decorations, laces with designs, tapes, appliqués, meshes, etc., as well as fabrics with relatively fine textures or stitches, and these. Stretchable or elastic fabrics are more preferred. Incidentally, these cloths may be made into a tube shape and cover the parison. Alternatively, adhesive or adhesive may be applied to the cloth in advance.
布地がレース、テープ、アップリケ或いは極めて薄いな
どの場合には比較的剛性を有する布を裏打らすることが
好ましい。When the fabric is lace, tape, appliqué, or very thin, it is preferable to back it with a relatively stiff fabric.
次に上記した布で中空成形用の金型のキャビティをパリ
ソンを覆うようにして張った状態で覆い、連続成形に便
なるように金型外の上下でロール状に巻いた該布地の一
部を固定するか、又は粘着テープ、接着テープもしくは
接着剤、粘着剤などにより周端部を使用後簡単に取り外
Ｕる方法で固定しておく。Next, the cavity of the hollow molding mold was covered with the above-mentioned cloth in a stretched state so as to cover the parison, and a portion of the cloth was rolled up above and below the outside of the mold to facilitate continuous molding. Alternatively, the peripheral end portion may be fixed with adhesive tape, adhesive tape, adhesive, adhesive, etc. in such a way that it can be easily removed after use.
また、布を張設する方法として、パリソンの直下にエヤ
シリンダー等を用いた上下動のできる布地支持筒を設置
し、該支持筒の下降時に、丸編みの繊維布を上端を若干
はみださせて、その支持筒に被覆した後、該支持筒を上
昇させて、その中にパリソンを内臓させると同時に、前
記の丸編みの繊維の上端のはみ出し部を固定具で金型に
固定し、次いで支持筒を下降せしめることによって張設
することもできる。In addition, as a method for stretching the cloth, a fabric support tube that can be moved up and down using an air cylinder or the like is installed directly below the parison, and when the support tube is lowered, the circular knitted fiber cloth is slightly protruded from the top end. After covering the supporting cylinder, the supporting cylinder is raised to incorporate the parison therein, and at the same time, the protruding part of the upper end of the circular knitted fiber is fixed to the mold with a fixture, It can also be tensioned by then lowering the support cylinder.
金型をセットした際、布地が皺になると成形品の外観を
損ねる原因となるので避けるべきである。Wrinkling of the fabric when the mold is set should be avoided as this will impair the appearance of the molded product.
この後、金型を閉鎖係合すると、布に張力がかかり、パ
リソンを覆うようにして金型内に張設、すなわち、張っ
た状態で設置され金型の準備が整う。Thereafter, when the mold is engaged in a closing manner, the fabric is tensioned and placed taut in the mold over the parison, readying the mold.
本発明で用いられる合成樹脂は従来中空成形用樹脂とし
て使用されていたものならいずれも用いることができる
。−例をあげると、ポリプロピレン、ポリエチレン等の
ポリオレフィン系樹脂、塩化ビニル系樹脂、ＰＥＴ樹脂
、ポリアミド系樹脂、ＰＳ、ＡＢＳ、）−ＩＩＰＳ等の
ポリスチレン系樹脂等である。As the synthetic resin used in the present invention, any synthetic resin conventionally used as a blow molding resin can be used. Examples include polyolefin resins such as polypropylene and polyethylene, vinyl chloride resins, PET resins, polyamide resins, and polystyrene resins such as PS, ABS, )-IIPS, etc.
布を張設した該金型が準備されたら、常法に従い、押出
ノズルより熱溶融樹脂を押出し、パリソンを形成せしめ
た後、金型を閉じ、その金型をセットする。次いで圧縮
空気をパリソン内に吹き込み、冷却固化すると表面に前
記した布が付着した加飾中空成形品が得られる。After the fabric-stretched mold is prepared, a hot molten resin is extruded from an extrusion nozzle to form a parison according to a conventional method, and then the mold is closed and set. Next, compressed air is blown into the parison, and when it is cooled and solidified, a decorated hollow molded article having the above-mentioned cloth attached to the surface is obtained.

。As the blow molding method used in the present invention, any conventionally known method can be used. For example, in order to increase the molding cycle, there are methods in which the parison is placed in the mold and then immediately moved to a different position to cool it, and plasticized resin is stored in a predetermined amount intermittently. A method such as extrusion to form a parison can be appropriately selected and used.
