も提案されている。2. Description of the Related Art Today, many small home-use offset parabolic antennas are used as means for receiving television broadcasts using SHF-band broadcast satellites. The parabolic antenna is manufactured by drawing a metal foil such as aluminum into a radial surface, plating the surface for rust prevention, or providing a coating layer, and resin molding including an FRP molded body. SM that adheres or deposits a metal film on the parabolic form of the body, then stacks SMC (sheet molding compound), and compression-molds it with a mold
The C method has been proposed. Furthermore, after the radio wave reflection layer is coated on the mirror surface of the mold by metal spraying in advance, the mold is closed, the thermoplastic resin is injection-molded in the cavity, and the surface of the resin molded body is released from the mold. A method of coating a decorative layer has also been proposed.

経時変化によって変形しやすくなる欠点があった。In the conventional method for manufacturing a reflector for a metallic parabolic antenna, a large amount of scrap is generated because a rectangular metal foil is punched into a circle and drawn. In addition, after the drawing process, secondary processing is required by cutting or polishing the resin molded body, which increases the number of steps, and when the mounting bracket is attached to the back surface of the obtained resin molded body, the welding heat distorts the reflector. There was a problem such as. Therefore, many reflectors for parabolic antennas made of synthetic resin are adopted today. However, even in the case of the parabolic antenna reflector made of synthetic resin, the SMC method has a drawback that the obtained reflector is easily deformed due to aging because the SMC is molded by a large pressing force.

めコスト高になる欠点があった。On the other hand, the injection-molded synthetic resin reflector has a small amount of deformation over time, but when a metal film is adhered or vapor-deposited on the surface of the resin molded product to attach a radio wave reflection layer, this thickness It is very difficult to adjust the height to a constant level, which reduces the mirror surface accuracy and requires coating of a rust preventive layer on the radio wave reflection layer, which requires a lot of man-hours to reach the finished product. Since a long molding time is required, there is a drawback that the cost becomes high.

Also in this case, it is necessary to spray the radio wave reflection layer on the surface of the mirror surface of the mold for each molding, and then to perform the injection molding after drying, and this molding method also takes a long time. The present invention addresses such a problem and improves it by injection molding a reflector for a parabolic antenna made of synthetic resin and simultaneously forming a thin uniform radio wave reflection layer and a decorative layer on the parabolic shape surface. Provided is a method for manufacturing a reflector for a parabolic antenna, which is adhered and shortened in molding time.
