PURPOSE:To eliminate tire defects caused by wrong thermal processing and thereby improve tire quality by using microwave energy as part of the heating energy for a heating mold, and controlling the direction of the microwave for vulcanization of various sites of a tire at different temperatures. CONSTITUTION:Microwave guides 3 are provided on the top and bottom of a heating mold 1. The microwave energy from the guides 3 is reflected by microwave reflectors 2, 2 provided on the top and bottom of the mold 1 so as to radiate toward the entire periphery. The blades 8 of a microwave agitator are provided between the upper and lower reflectors 2, 2. By adjusting the incidence angle of the blades 8, the microwave energy applied to the a specific site can be increased. Accordingly, since the microwave energy can be concentrated on a specific site of a tire, the various sites of the tire can be vulcanized at different temperatures. The apparatus and method thus prevents defects otherwise caused by incorrect thermal processing, improves the quality of tire and reduces the vulcanizing time. |
