本発明は時計用外装部品の製造方法に関するも
ので、薄肉時計用側を簡単な工程によつて安価に
かつ自由なデザインで生産しうる方法を提供せん
とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing an exterior part for a watch, and aims to provide a method for producing a thin watch side through a simple process at low cost and with a free design. be.
従来薄肉時計用側の製造方法としては、一般的
に絞り加工・プレス加工の各工程を経て切削加工
等で所定の形状に製造する方法及びロストワツク
ス等の鋳造方法で成形した後切削加工等で所定の
形状に製造する方法等があつた。しかしながら上
記製造方法等には種々の欠点があつた。 Conventional methods for manufacturing thin-walled watches include a method of manufacturing into a predetermined shape by cutting, etc. after each process of drawing and press working, and a method of forming by a casting method such as lost wax, and then cutting into a predetermined shape, etc. There was a method to manufacture it in the shape of . However, the above manufacturing methods have various drawbacks.
絞り加工については、加工上の問題に起因する
板厚・形状・デザインの制約がある。特に板厚の

ストアツプ要因となつていた。また時計のフアツ
シヨン化が進み、デザインの多様化を優先した場
合、絞り加工工数の増加を招くばかりでなく加工
そのものが不可能となつてしまう。 Regarding drawing processing, there are restrictions on plate thickness, shape, and design due to processing issues. Particularly in terms of plate thickness constraints, it is extremely difficult to draw ultra-thin plates from the perspective of drawing processing, and this is a major hurdle in dealing with the trend towards thinner plates. Furthermore, since the plate thickness could not be made thinner, the amount of material used for the watch side increased, resulting in a significant cost increase for watch bodies, especially products that used precious metals. Furthermore, as watches become more fashionable and diversification of designs becomes a priority, not only does the number of drawing processes increase, but the process itself becomes impossible.
プレス加工においても絞り加工同様に加工上の
問題に起因する板厚・形状・デザインの制約があ
る。さらにプレス加工上発生するバリの除去にも
多大な工数がかかり、材料費のコストアツプにつ
ながつていた。 Like drawing, press working also has restrictions on plate thickness, shape, and design due to processing problems. Furthermore, removing burrs generated during press processing requires a large amount of man-hours, leading to an increase in material costs.
鋳造方法においては、絞り加工及びプレス加工
に比較して形状の制約が少なく時計用側として使
用する原材料も少なくてすむ。このため貴金属時

巣の発生という欠点があり外観品質を重視する時
計用側への適用はまだ困難であり、また薄肉化の
面でも鋳造不良(特に湯回り性)が起り問題点と
して残つている。 Compared to drawing and press working, the casting method has fewer restrictions on shape and requires less raw material for the watch. For this reason, it is most suitable for manufacturing precious metal watches, but on the other hand, casting has the disadvantage of generating cavities, so it is still difficult to apply it to watches where appearance quality is important. Defects (particularly in hot water running) have occurred and remain a problem.
以上の説明通り現行製造方法では、薄肉時計用
側を製造する上で、形状・板厚・デザインの制約

そこで本発明の目的は、上記の欠点を解決する

約を受けずに容易に製造せんとするものである。 Therefore, the purpose of the present invention is to solve the above-mentioned drawbacks by combining injection molding and surface treatment technology, thereby making it possible to easily manufacture thin-walled watch sides at low cost and without being subject to restrictions on plate thickness or shape. This is what I am trying to do.
以下本発明の要旨を図面にそつて説明する。 The gist of the present invention will be explained below with reference to the drawings.

製造する。 In FIG. 1, reference numeral 1 designates a male mold for a watch exterior part made of a chemically dissolvable plastic material which is injection molded. Examples of the material for the male mold 1 include injection moldable plastic materials such as ABS resin, polycarbonate resin, polyphenylene, nylon, polysulfonate, fluorine resin, styrene, epoxy resin, and phenolic resin. Since a metal layer will be formed on the outer peripheral surface of the male mold 1 in the next step, it is manufactured in advance to a predetermined size by reducing the thickness of the metal layer 2. Next, as shown in FIG. 2, the surface of the male mold 1 of the watch exterior part is subjected to surface treatment, and a metal layer 2 is deposited until it reaches the size of the watch side, thereby producing a complete watch side body.

ト的メリツトが無くなる。 The material of the metal layer 2 is Ni.Pd.Au.Ag.Rh.
Examples include Ru or alloys thereof, and multilayer coatings of the above materials. The thickness is set to 50 to 500 μm. Considering the watch side currently in use, if the thickness is less than 50 μm, there is no strength and it cannot be used as a watch side, causing damage to the movement, but if it is over 500 μm, it can be manufactured by drawing, which has cost advantages. It disappears.
以上の様な方法で製造した時計用側完成体に、

用する。 For the complete watch side manufactured by the method described above,
As shown in FIG. 3, a machined hole 3 is provided on the inner surface so that the male die 1 can be chemically dissolved. Next, the male mold 1 is selectively chemically dissolved in the outer peripheral metal layer 2 of the completed watch side part to produce a male mold 4 of the watch exterior part. This male mold 4 is subjected to simple cutting and polishing and used as a watch side.

つた。 Since the watch side according to the present invention combines injection molding and surface treatment, it has good dimensional accuracy, which is a feature of the injection molding method, and can press product dimensions to a tolerance of 2/1000 to 3/1000 mm. It is. The constraints on shapes have expanded dramatically, and almost any shape can be created as long as a mold is available. Furthermore, by using surface treatment technology, the thickness of the plating layer, that is, the thickness of the watch side, can be adjusted to match the material strength and the strength of the watch side, making it possible to obtain an extremely high quality watch side. In addition, the plate thickness, shape, and
Problems such as design processing can be solved, and manufacturing man-hours and
This made it possible to significantly reduce costs in terms of both materials, which was extremely effective for the production of gold-plated watches.
