〔発明の目的〕
（産業上の利用分野）
本発明は、射出成形により得られる部品に、特に金属光
沢模様をなす樹脂フィルムをインサートするための型内
絵付方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an in-mold painting method for inserting a resin film having a particularly metallic luster pattern into a part obtained by injection molding.
（従来の技術）
従来、第２図に示すように、射出成形をなすための成形

態で射出成形すると、完成した部品には樹脂フィルムが
同一面でインサート成形なされる。(Prior Art) Conventionally, as shown in FIG. 2, a mold S, which is a mold for injection molding, is composed of a cavity a and a core b. In order to insert a resin film into the indexed molded product thus obtained, a film C whose surface is printed, for example, is adhesively held in the cavity a. When injection molding is performed in this state, a resin film is insert molded on the same surface of the completed part.

体感を得ることは困難である。However, even if the above-mentioned resin film is printed, it is not possible to obtain a metallic luster surface, which is far from giving a so-called luxurious feel. Also, even if you use a film that has been pre-deposited with metal,
It is difficult to express a metallic tone only in a part of characters or designs, and it is especially difficult to express a metallic tone at all when the shape is complex, and it is also difficult to obtain a three-dimensional effect.

た金型を押し当てて転写するものである。Incidentally, hot stamping is known as a means of obtaining a metallic tone and a certain degree of three-dimensional expression. This involves holding metal foil such as aluminum or chrome on the back of a transparent synthetic resin molded product or the front of a paper product such as an album, and then pressing a mold with a protruding pattern onto it to transfer the pattern. It is.

のは、従来のごとき刻印ホットスタンプを用いるには遇
ざない。Such hot stamping is advantageous when requirements for wear resistance and weather resistance are low. In other words, the hot-stamped surface tends to peel off with use and loses its metallic luster when exposed to wind and rain. Therefore, for things that require a high degree of durability, such as exterior parts of automobiles, it is not possible to use the conventional stamping hot stamp.

能な型内紛付方法を提供することを目的とする。(Problems to be Solved by the Invention) The present invention eliminates the above-mentioned problem of reduced abrasion resistance and weather resistance on treated surfaces with metallic luster, and has a high degree of durability. The purpose of the present invention is to provide an in-mold mixing method that can also be used as an exterior part.

記コアｂに対向することとなる。(Example) Hereinafter, an example of the present invention will be described based on FIG. For example, a mold S, which is a mold for injection molding parts that constitute the exterior parts of an automobile, has a cavity a and a core b.
This is the same as before. For example, the insert film 1 is adhesively held at a predetermined position in the cavity a. This may be accomplished by using an adhesive tape or by providing a hole in the cavity a that communicates with a vacuum source and drawing a vacuum. The insert film 1 is made of a transparent resin film 3 with a hot stamp 2 stamped on the back surface. This transparent resin film 3 is made of, for example, PMMA or PC. The engraving hot stamp 2 is applied to a part of the transparent resin film 3, and is made of aluminum or chrome material subjected to brightening treatment (metallizing treatment). The transparent resin film 3 is directly adhered to the cavity a, and the hot stamp 2 faces the core b.

When the insert film 1 is removed, the insert film 1 is inserted into the cavity a.
It is then peeled off and inserted into the surface of the completed molded product. That is, the surface of the molded product and the insert film 1 are on the same surface, and the hot stamp 2 is interposed between the transparent resin film 3 and the molded product.

たとえば自動車の外装部品に最適である。In other words, the engraved hot stamp 2 is sealed and protected by the transparent resin film 3, so that it is not directly damaged and is not exposed to wind and rain. In other words, it will not deform or change color even after long-term use.
Highly durable. Moreover, it looks good because it has a glittering pattern with a three-dimensional effect. in any case,
For example, it is ideal for automobile exterior parts.
以上説明したように本発明によれば、耐摩耗性。 As explained above, according to the present invention, wear resistance is achieved.
