Abstract
Electromagnetical heating method instead of heat plate in vulcanizing machine and forming machine is adopted in the invention. Under action of AC current, magnet coil generates AC magnetic field. Through steel mould, the magnetic field generates loop, forming induced vortex current inside steel mould. Through resistance of steel mould, energy of current is transformed to heat energy directly. Shielding magnetic block on other side makes magnetic flux generated by magnet coil possess directivity in order to prevent electromagnetical leak. Features are: high efficiency of heat transform, quick heating, safe and energy saving and avoiding electromagnetical leak.
