In the figure, 7 is an upper mold, 8 is a lower mold, 9 is an upper mold cavity, and 10 is a lower mold cavity. These molds 7 and 8 are made of dielectric loss angle (tan δ )
It is made up of small pieces of material. Further, these molds 7 and 8 are connected to cooling water pipes 11 and 12 through which cooling water is passed for cooling the molds. 13 is an upper electrode, 14 is a lower electrode, and 15 and 16 are cooling channels provided to prevent these electrodes 13 and 14 from generating heat. 17 is a predetermined position of the bright protrusion, and 18 is a thermoplastic resin molded product. The main body is formed from this thermoplastic resin molded product 18. Place the lower mold cavity 10 with the surface of the bright protrusion 4 facing downward.
Place the thermoplastic resin molded product 18 at a predetermined position 17.
After filling the lower mold cavity 10, the upper mold 7,
The lower mold 8 is closed and pressurized, and a high frequency voltage is applied to the upper electrode 13 and the lower electrode 14 facing each other by a high frequency oscillator. At this time, as mentioned above, since the molds 7 and 8 are made of a material with a small dielectric loss angle (tan δ), the molds 7 and 8
8 generates little heat, and the thermoplastic resin molded product 18 generates self-heating, softens and melts itself, is molded into a predetermined shape in contact with the cavities 9 and 10, and is painted on the back surface of the bright protrusion 4. Since it is the same resin as the adhesive liquid, it is completely integrated and adhered. At this time, the heat generated on the surface of the bright protrusion 4 is absorbed by the lower mold 8, and the bright surface is not affected in any way.
After that, the application of the high frequency voltage is stopped, and the cooling water pipe 1
Cooling water is passed through molds 1 and 12 to cool molds 7 and 8. After cooling, the mold is opened and the product is taken out.

減が可能である。(Effects of the Invention) The automobile ornament according to the invention has a shiny protrusion having a metallic luster surface with a three-dimensional effect, and therefore has excellent aesthetic appearance and improved decorativeness. Since the bright protrusion is welded and adhered to the main body by high frequency heating, it is completely integrated and has excellent adhesion. The process of high-frequency heating is simple, as it heats and melts the material by utilizing the electrical properties of the plastic material, so the heating process is reliable, and the material is heated by self-heating. Therefore, it is possible to uniformly heat and melt the material from the inside to the surface, which has a great effect not only on the appearance of the molded product but also on its physical properties.The heating effect is reasonable and good, and energy consumption is efficient. can be done. Furthermore, compared to conventional high-pressure molds, the mold itself can be made of thermosetting resin such as silicone resin, which can be easily made by casting, reducing manufacturing costs. It is possible to reduce
