BACKGROUND OF THE INVENTION Synthetic resin molded products whose surfaces are hardened to improve scratch resistance and abrasion resistance are used for vehicle finishers, windows, and the like. Figure 1 is a system diagram showing the conventional manufacturing method for vehicle finishers, which are synthetic resin molded products. The material 1 is immersed in a degreasing tank 2, degreased and cleaned with a cleaning solvent such as normal hexane, and after drying,
After uniformly applying a treatment solution such as SiO 2 solution by immersion in a hardening treatment tank 3, that is, by dipping, flow coating, spraying, etc., the finished product 4 is subjected to surface hardening treatment by drying (baking). As such a method, for example, Japanese Patent Application Laid-Open No. 1983-

れ、実用に供し得ない。 When the molded product is a window, it is necessary to use transparent synthetic resin to allow light to pass through, and if flow marks or weld lines occur on the outer surface of the material, they cannot be covered up even in the finished product. Therefore, it is completely visible and cannot be put to practical use.

In this invention, a transparent thermoplastic synthetic resin film 5 having a hardened film layer 5b formed on its surface is set in a direction in which the hardened film layer 5b faces the mold surface in a cavity 11 of an injection mold. After the mold is clamped so that a cavity 11 is formed between the base 5a surface and the other mold surface, heated and melted liquid synthetic resin is injected into the cavity to fill the cavity 11, This method of manufacturing a resin molded product is characterized by molding a molded product body 4a and integrally laminating a film 5 on the surface of the molded product body 4a.

An embodiment of the present invention will be described below with reference to the drawings. Fig. 2 is a front view showing a state in which a synthetic resin film with a hardened film layer formed on its surface is vacuum formed, Fig. 3 is an enlarged partial cross-sectional view of the synthetic resin film, and Fig. 4 is a cross-sectional view showing an injection molding state. FIG. 5 is a sectional view of the finished product. In this example, the finished product 4 of the vehicle finisher shown in FIG. 5 is manufactured. First, the synthetic resin film 5 shown in FIG.
is formed into a shape that approximates the surface shape of the finished product 4 by the method shown in FIG. The synthetic resin film 5 has a base 5a made of a transparent thermoplastic synthetic resin such as polymethyl methacrylate resin or polycarbonate resin, and a hardened film layer 5b made of a silicone hard coat or the like is formed on preferably one surface of the base 5a. The method of forming the cured film layer 5b on the film 5 is to directly coat a wide flat original film made of polymethyl methacrylic resin or polycarbonate resin formed to a thickness of about 0.05 mm to 1.0 mm. Alternatively, after forming the primer layer, a cured film layer is formed by a known method. A molded product with a complex external shape may be thin, and a flat product may be thick, and in reality, it is about 0.125 to 0.5 mm. In this case, a cured film layer can be formed on the entire surface of a wide film base, and the film can be kept flat, so even if a liquid solution is used to form a cured film layer, local sag etc. will not occur. It can be formed smoothly and with uniform thickness over the entire surface.

剤層を予め形成しておくとよい。 The film 5 with the cured film layer 5b formed in this way
is placed above the vacuum forming mold 6 as shown in FIG. Vacuum forming is performed by adhering to the The film 5 thus formed into a shape similar to the surface shape of the finished product 4 is cut to an appropriate size.
Next, injection molding is performed. That is, in FIG. 4, the cavity mold 8 and core mold 9 of the injection mold
In between, the cured film layer 5b of the film 5 is arranged so as to face the surface of the cavity mold 8, and the base 5a is arranged so as to face the surface of the core mold 9, so that a cavity (gap) 11 is formed between the base 5a and the core mold 9. Insert injection molding is carried out by sandwiching the film 5 so that it is formed, and injecting heated and molten liquid transparent resin from the gate 10 into the cavity (gap) 11. The resin to be injected at this time is preferably a resin that is compatible with the base 5a of the film 5. In particular, if the resin is made of the same material, the surface of the base 5a on the cavity 11 side will melt due to the heat of the injected resin, and they will mutually interact. It is preferable because it welds firmly. When the two are not compatible, it is preferable to form an adhesive layer in advance on the surface of the base 5a opposite to the surface on which the cured film is applied.

い。 Furthermore, in this embodiment, since the injected high-temperature molten resin does not come into direct contact with the surface of the cavity mold 8, that is, the film 5 serves as a heat insulating material, so that it rapidly cools and solidifies on the side of the cavity mold 8. Therefore, flow marks and silver are less likely to occur. Also, since the flow resistance of the resin within the cavity 11 is reduced, the cavity 1
It is possible to easily spread the resin to every corner of the window, so a low injection pressure is required, making it particularly suitable for manufacturing windows with relatively small wall thickness and large area. Furthermore, weld lines are less likely to occur.
以上の作用効果は、フイルム５をキヤビテイ型
８面だけでなくコア型９面側にも配置して両フイ
ルム間のキヤビテイ１１に樹脂を射出する場合に
は、顕著な作用効果となつて現われる。 The above-mentioned functions and effects become significant when the film 5 is arranged not only on the 8th side of the cavity mold but also on the 9th side of the core mold and the resin is injected into the cavity 11 between the two films.
さらにウインドウのように成形品の表面に鏡面
に近い平滑さを要求されるものであつても、平滑
な表面のフイルムを使用すればキヤビテイ型８面
を鏡面仕上げしなくても、鏡面に近い平滑な外表
面を有する成形品が得られる。 Furthermore, even if the molded product surface is required to have a mirror-like smoothness, such as a window, by using a film with a smooth surface, you can achieve a mirror-like smoothness without having to mirror-finish the eight sides of the cavity mold. A molded article having a uniform outer surface is obtained.

の向上した成形品として完成する。 The molded product thus formed is taken out by opening the cavity mold 8 and core mold 9 of the metal mold, and the necessary portions are trimmed to obtain the finished product 4. As shown in FIG. 5, the finished product 4 has a molded product main body 4a made of transparent resin.
The film 5 is closely bonded and integrated, and a molded product having a hardened film layer on the surface and improved scratch resistance and abrasion resistance is completed.

デイングを行つてもよい。 The above embodiments are based on the premise that the finished product 4, such as a finisher, is attached to the body of a vehicle and it is usually sufficient to provide a hardened film layer only on the outer surface side, and the film 5 is bonded only on one side. However, in cases where a hardened film layer is required on both the front and back surfaces, such as a vehicle window, two films 5, 5 are prepared, and the hardened film layer 5b is formed on the cavity mold 8 and core mold 9 surfaces, respectively. Insert injection molding may be performed such that resin is injected into the cavity 11 formed between the bases 5a and the bases 5a, and the resin is bonded to both sides.

ことが可能である。またフイルム５の成形も真空
成形のほかに、ホツトプレスその他の方法による
ことも可能である。 Further, the film 5 may be formed by direct injection molding using the cavity mold 8 and the core mold 9, that is, by softening the film to some extent by the heat of the injected resin and plastically deforming it so that it conforms to the mold surface. Particularly when the surface of the molded product has few steps or irregularities, it is possible to omit vacuum forming and directly set the film in a mold to produce a desired molded product. In addition to vacuum forming, the film 5 can also be formed by hot pressing or other methods.

である。 This invention is applicable not only to vehicle finishers, but also to synthetic resin molded products for other uses such as windows, lenses, and even transparent covers for office automation equipment.
以上のとおり、この発明によれば、次のような
効果を奏する。 As described above, the present invention provides the following effects.
表面に硬化皮膜を形成したシートまたはフイ
ルムを接合するので、従来の成形品の直接処理
に比べて工程が短縮される。 Since a sheet or film with a hardened film formed on the surface is bonded, the process is shorter than the conventional direct processing of molded products.
