PURPOSE:To make it possible to imbeddingly mold both a weatherable synthetic resin sheet on one side and insert members on the other side of a molded item simultaneous ly and integrally by a structure wherein vent pieces, which are connected to a suction apparatus outside an equipment, are provided on the cavity surface of a top force and pins, by which the insert members are supported, are installed in upright position on the cavity surface of a bottom force. CONSTITUTION:A weatherable resin sheet 17, which forms the surface side of an antenna, is sucked through ventpieces 5 onto the cavity surface 3 of a top force 1 by actuating a vacuum pump. On the other hand, nuts 18, which are insert materials, are screwed onto the tips of pins 13, which protrude from the cavity surface 4 of a bottom force 2. After that, an aluminum sheet 20 and a sheet 19 made of unsaturated polyester resin, for example, is placed onto the cavity surface 4 in the order named and then the top force 1 is pressingly fixed to the aluminum sheet 20 under heat and pressure. And, by stopping the vacuum pump and shifting the top force 1 upwards, a molded item is left on the cavity surface 4 of the bottom force 2. After this state, the molded item is released from the bottom force by ejecting ejector pins 10, which are integrally attached to a bottom force plate 11, beyond the cavity surface 4 through the actuation of a hydraulic cylinder 16. |
