Injection molding hyperboloid reflector and injection molding method thereof

The invention provides an injection molding hyperboloid reflector and an injection molding method thereof. The injection molding hyperboloid reflector comprises a pedestal which is obtained by employing an injection molding process and provided with a hyperboloid concave surface, and a reflecting layer connected to the concave surface. The pedestal is integrated through injection molding; the reflecting layer is connected to the pedestal concave surface through the vacuum coating technology. The pedestal which is obtained through injection molding and provided with a hyperboloid concave surface has sound moldability, is convenient to install and transport, and can better protect the reflecting layer in a transportation process. The pedestal preferably employs engineering plastics capable of injection molding, has great weatherability, is hard to deform, guarantees the service life of the hyperboloid reflector, and is light; meanwhile, the tolerance between the dimension of the hyperboloid concave surface of the hyperboloid reflector and the dimension of a theoretically calculated curved surface is small, and the hyperboloid concave surface is almost identical with a designed curved surface, has excellent light condensing effects, and can improve a light utilization rate. The injection molding method is simple to operate.
