に押付けられる。When the female mold 1 is sealed by S or J, the sheet 3 is preformed as shown in FIG. During preforming, compressed air is first exhausted from both the vents 1r and 2A, and then compressed air is cut off from the vent J. In this way, the sheet 3 is pressed against the inner surface of the female mold.

On the other hand, according to the former method, air remains in the female mold during preforming, so there is no need to provide a large number of ventilation holes fi, and there are no traces of the ventilation holes r on the surface of the molded product after molding. I never get it.

The liquid is injected from the injection hole into the cavity. Then, the sheet 3 is pressed by the molten resin 31 against the high frequency embossing device 10 in the female mold, and is embossed. This embossing molding is continuously performed from the time of injection molding to the completion of injection molding. At this time, the sheet 3 and the surface 1 of the molten resin are softened by the high frequency and conform to the cavity surface, so that even small irregularities can be accurately molded.

する。In addition, 33 in the figure is a letter. As mentioned above, in the present invention, a high frequency embossing device is incorporated into the female cavity surface of the simultaneous injection embossing device, so there is no unevenness or reverse tapered underside on the surface. A molded product with many cut parts can be easily molded without using a split mold. Furthermore, since the sheet can be fed at a constant pitch, it is possible to accurately match the irregularities of the molded product with the pattern on the sheet.
