Title: Manufacture of reflecting plate for antenna
Inventor: IZUMIHARA HIROSHI
IPC: B29C45/14
Filed: 1990-10-30
Abstract: PURPOSE:To mold the reflecting surface in which the strain due to the residual stress in a film does not occur by a method in which a thermoplastic resin film is sucked and heated by a platen, and is transferred to the front surface of a movable mold, and a reflecting plate is injection-molded from the state where the heated resin film is brought in contact with the cavity-constituting surface of the movable and is stuck by suction thereto. CONSTITUTION:In the injection-molding of an antenna body B, the body B is simultaneously covered with resin films X, thereby forming a current-reflecting layer X2 and a weathering resistant layer X3. Since the vacuum and pressurizing molding of the resin film X is achieved by sufficiently softening the resin film X by a platen, even if the resin film X is sucked on a cavity-constituting surface 39 by vacuum and pressurizing molding and is deformed with its extension so that the film X is brought in contact with the cavity-constituting surface 39 by injection molding, the stress accompanied by its elongation and deformation does not occur in the film. Consequently, in the produced reflecting plate A, residual stress does not exist in the resin film with which the reflecting surface is covered, whereby the strain due to the residual stress does not occur on the reflecting surface.

At each angle protrusion 4 part, the reinforcing cord 8 is embedded along the peripheral surface, only in the vicinity of the peripheral surface. A metal ring 9 is embedded inside of each angle protrusion 4 and in the inner layer 6 away from the reinforcing cord 8. The outer layer 7 can therefore be elongated in the state of the angle protrusion 4 becoming low while the reinforcing cord 8 approaches the metal ring 9, and the inner layer 6 at the angle protrusion 4 part is also elongated along with the outer layer 7. A connection part to piping is therefore prevented from being damaged or coming off by the change of external force.
