Mold device. [Prior Art] A machine that manufactures a paper lunch box is provided with a heating device before the mandrel structure, and a paper sheet having a film on the surface is heated by a heating device when the film is passed through the heating device. Then, the paper sheet continues to enter between the upper and lower molds of the mold structure, and the upper and lower molds are closed to form a shape for the meal, and the corners around the paper lunch box are heated by the film. The phase is sticky, so that the finished paper lunch box can be folded after the mold is clamped. The above-mentioned device for manufacturing the paper lunch box can heat the paper sheet and use the mold structure to process the finished product, but the paper sheet is heated and molded by the mold. There is a time difference, so the processing procedure of the two productions increases the manufacturing time and can not effectively increase the output. In addition to the film, the surface of the film is heated by the film and cooled by the mold. The rickshaw worker, & Fenyi produces friction wrinkles on the surface, and the twisting device increases the efficiency of the paper across the space. ', ... the hands are poor, so the electricity consumption is large and the power is wasted and energy is wasted. SUMMARY OF THE INVENTION Since the existing paper lunch box is first heated by a heater and then formed into a mold, the surface is easily broken, the processing is slow, and the power consumption is large. To this end, the main object of the present invention is to provide a structure in which an electrode can be electrically connected between the upper and lower molds, and a step of heating and bonding the paper lunch box with a high frequency at the same time to achieve a relatively fast manufacturing effect.
