〔産業上の利用分野〕
本発明は、ダイカスト鋳造やプラスチック射出成形等の
製造方法で製作する時計ケースの金型構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mold structure for a watch case manufactured by a manufacturing method such as die casting or plastic injection molding.
従来は第４図に示すように、６はキャビティでありコア
１が係合されており、コア１の上部より座グリ３を設は
コア支え２に表よりネジ止めしていた。Conventionally, as shown in FIG. 4, numeral 6 is a cavity in which the core 1 is engaged, and a counterbore 3 is provided from the top of the core 1 and screwed to the core support 2 from the front.
しかし、前述の従来技術ではコアを止める際には、例え
ば極小時計ケース用のコア１をコア支え２に止める場合
、コア１が小さいため表より座グリ３をすると残り肉１
ａがなくなってしまい、極小時計ケースの製造ができな
いという問題を有する。However, in the above-mentioned conventional technology, when fixing the core, for example, when fixing the core 1 for an extremely small watch case to the core support 2, since the core 1 is small, if the core is counterbore 3 from the front side, the remaining thickness is 1.
The problem is that a is missing, making it impossible to manufacture extremely small watch cases.
又、多少残り肉があっても座グリ３の部分に湯（溶けた
材料）が差して、ネジを取ることができないと言う問題
も生じ、そのために段取作業毎に１０分位のムダな時間
を要していた。In addition, even if there is some remaining meat, hot water (melted material) may be poured into the counterbore 3, making it impossible to remove the screws, which results in a waste of about 10 minutes per setup. It took time.
そこで本発明はこのような問題を解決するもので、その
目的とするところは極小時計ケースの製造をする金型構
造を提供するところにある。SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and its purpose is to provide a mold structure for manufacturing extremely small watch cases.
本発明の時計ケース金型構造は、入れ子方式金型におけ
る時計ケース用コアを、コアの裏面よりネジ止めするこ
とを特徴とする。The watch case mold structure of the present invention is characterized in that the watch case core in the nesting mold is screwed from the back side of the core.
以下に本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below based on the drawings.
第１図は本発明の実施例における、ダイカスト用金型の
キャビティプレート部の平面図を示す。FIG. 1 shows a plan view of a cavity plate portion of a die-casting mold in an embodiment of the present invention.
８はキャビティプレートであり、該キャビティプレート
８には、キャビティ６と、コア支え２と、エジェクター
ビン７とが係合されている。8 is a cavity plate, and the cavity 6, the core support 2, and the ejector turbine 7 are engaged with the cavity plate 8.
第２図は第１図のＡ−Ａ’断面図である。裏面にネジを
切られたコア１は、コア支え２の裏側よリネシ止めされ
る。コア支え２には表側に案内溝４が設けてあり、コア
の位置出しが容易にできるようになっている。FIG. 2 is a sectional view taken along the line AA' in FIG. The core 1, which has a thread cut on its back surface, is fixed to the back side of the core support 2 by threading. A guide groove 4 is provided on the front side of the core support 2 so that the core can be easily positioned.
第３図は本発明の他の実施例を示す部分断面図であり、
第２図の案内溝４の代わりに案内ビン５をコア支え２に
配設しコア１に案内ビン５が係合される穴部を形成して
係合しコア１の位置出しを行う。FIG. 3 is a partial sectional view showing another embodiment of the present invention,
A guide pin 5 is provided in the core support 2 in place of the guide groove 4 shown in FIG. 2, and a hole in which the guide pin 5 is engaged is formed in the core 1 so that the core 1 is positioned.
このような構造にすることにより、コアが小さくなって
もコアの残り肉がなくなること及び、座グリ部分に湯が
差すと言った問題は生じなくなるのである。By adopting such a structure, even if the core becomes smaller, there will be no remaining meat on the core, and problems such as hot water being poured into the spot facing portion will not occur.
又、コア支えへのコアの取り付は方法はネジ止めであり
、従来のコア表面よりネジ止めする場合と、極小モデル
のコア裏面よりネジ止めする場合も、コア支えを変える
のみで他は共通に使用できるのである。In addition, the method of attaching the core to the core support is by screwing, and whether it is screwed from the front surface of the conventional core or from the back of the core of an ultra-small model, the only difference is the core support, and everything else is the same. It can be used for.
又、この製造方式は金属鋳造やプラスチック射出成形に
も応用可能である。This manufacturing method can also be applied to metal casting and plastic injection molding.
以上述べたように本発明によれば、入れ子方式金型の時
計ケース用コアを、コアの裏面からネジ止めすることに
より、コア表面の輪郭形状および大きさには影響される
ことなくコア裏面にネジ止めに必要なスペースか確保で
きればコアの成形が可能となるので、極小時計ケースを
製造することができると言う効果を有する。As described above, according to the present invention, by screwing the watch case core of the nesting mold from the back side of the core, the core can be attached to the back side of the core without being affected by the contour shape and size of the core surface. Since the core can be molded as long as the space necessary for screw fixing can be secured, it has the effect of making it possible to manufacture extremely small watch cases.
又、時計ケースに限らず袋形状をした時計ケース以外の
部品へのバラエティ化を計る応用効果も有、する。Moreover, it has the effect of being applied not only to watch cases but also to various parts other than bag-shaped watch cases.
