However, the above-mentioned conventional method for manufacturing a molded and decorated article has the following problems. In other words, in the resin forming technology in which a pattern layer is formed on the surface of a molded article by transfer at the same time as molding, the amount of heat of the molten resin injected into the cavity is will be taken away. Therefore, it was inevitable that the fluidity of the molten resin would be poorer than in a simple resin forming technique. When the molded article is thin, when the molded article rises, when the molten resin of the molded resin is high, when the melting temperature of the molded resin is high, when the molded resin contains filler, etc., the fluidity of the molten resin may be affected. It was supposed to further impede the Such poor fluidity of the molten resin has brought about the following problems. That is, when the cavity of the mold is filled with molten resin, the pressure applied to the molten resin becomes uneven, and the adhesive layer of the decorative sheet is washed away. As a result, there was a problem in that the adhesion between the molded article and the pattern layer transferred to the surface of the molded article was insufficient. In order to improve this adhesion, heat treatment is sometimes performed after molding, but not only is the effect small, but there is a risk that the latent residual distortion that occurred during molding may be revealed by the heat treatment.

Further, when the molten resin is cooled and solidified, there is a difference in cooling temperature between the surface that is in contact with the decorative sheet and the surface that is not. As a result, a problem arises in that the molded article is likely to warp or twist.

As the decorative sheet 1, those commonly used in resin molding technology in which a pattern layer is formed on the surface of a molded article by transfer at the same time as molding may be used. Such decorative sheets 1 include transfer sheets and insert sheets. The basic layer structure of the transfer sheet is such that a pattern layer P is provided on a base sheet having releasability, and an adhesive layer is provided thereon if necessary. Further, the basic layer structure of the insert sheet is such that the pattern layer P is provided directly on the base sheet without providing a release layer, and an adhesive layer is provided on the opposite side as necessary. The pattern layer P has various patterns depending on the purpose of the molded article. For example, when the purpose is a printed wiring board, an electric circuit pattern is formed, and when the purpose is a decorative board, a specified picture pattern is formed. Ru. When the decorative sheet 1 is a transfer sheet, it is fixed so that the surface opposite to the base sheet is located on the side that comes into contact with the molten resin. Moreover, when the decorative sheet 1 is an insert sheet, it is fixed so that the surface of the adhesive layer is located on the side that comes into contact with the molten resin. Note that two decorative sheets 1 may be used to form the pattern layer P on both the front and back surfaces of the molded article.

The third step is a step of injecting the molten resin 4 into the cavity 3 of the molding die 2. This cavity 3 is thicker than the wall thickness of the molded article,
By clamping the mold in the next step, the thickness is made the same as that of the molded article. Examples of the molten resin 4 include ABS resin, polycarbonate resin, polyacrylic resin, polystyrene resin, polyamide-based, polyester-based, urethane-based, styrene-based, and olefin-based thermoplastic elastomer resins used in this type of resin molding technology. In addition, it is possible to use polyethersulfone, polyetherimide, polyetheretherketone, polysulfone, polyarylate, polybutylene terephthalate, polyethylene terephthalate, etc., which have heat resistance and electrical properties. The temperature of the mold and resin when carrying out this process varies depending on the type of molding resin and the shape of the molded article, but the mold temperature is approximately 40 to 150 degrees Celsius.
The resin temperature is assumed to be in the range of 200 to 450°C.

The fourth step is a step of clamping the molding die 2 (see FIG. 2). This step is the most important point in the present invention. Molding mold 2 due to the previous process
After the molten resin is injected evenly into the cavity 3, the mold is immediately clamped to compress the molten resin 4 and obtain the desired molded article. At this time, the tip of the nozzle 5 for injecting the molten resin 4 is naturally closed (not shown). The mold clamping force varies depending on the type of molding resin and the shape of the molded article. Furthermore, it is also possible to apply mold clamping force in two or more stages, such that a weak force is applied at first and then a strong force is applied.

The fifth step is a step in which the molding die 2 is opened after the molten resin 4 is cooled and solidified. Further, the sixth step is a step of taking out the molded article from the molding die 2. These steps are the same as in conventional resin molding techniques of this type. Note that when the decorative sheet 1 is a transfer sheet, a step of peeling off the base sheet is required. When the decorative sheet is an insert sheet, the insert sheet is integrated with the molded article.

Since the present invention has the above configuration, the following effects can be obtained. That is, since the molten resin is injected while the mold is in contact and pressurized by clamping the mold, poor fluidity of the resin can be compensated for. In other words, since the cavity during injection is wider than that during cooling and solidification, the fluidity of the resin is improved accordingly. As a result, it becomes possible to inject the molten resin into the cavity at low pressure, allowing for more flexibility in resin molding conditions. Therefore, it is suitable when the molded article is thin, when the molded article has a rise, when the melt viscosity of the molded resin is high, when the melting temperature of the molded resin is high, when a filler is contained in the molded resin, etc. . Further, since the pressure is applied uniformly, it is possible to strongly adhere the surface of the molded article and the pattern layer. Further, since uniform pressure can be applied to the molten resin, a molded article with high molding accuracy can be obtained without warping or twisting. Furthermore, even if heat treatment is performed after molding to improve the adhesion between the surface of the molded article and the pattern layer, warping or twisting due to residual strain will not occur.
