1. An induction heating system for a silicon steel core with a self-adhesive coating, comprising:
a conveying roller table, with a plurality of stacking molds being conveyed thereon, each of the stacking molds configured and dimensioned to receive stacked silicon steel plates therein;
an induction heating device comprising a columnar induction heating coil with a hollow cavity and a temperature measuring element for measuring the temperature of the silicon steel plates, wherein the induction heating coil carries out induction heating on a silicon steel plate at a medium frequency of 6-20 KHz;
a feeding and discharging device which conveys each of the plurality of stacking molds in a horizontal direction; and
a loading and unloading device, which is configured to convey each of the stacking molds in the horizontal direction to a position directly below the induction heating coil, and convey the stacking mold in a vertical direction into the hollow cavity of the induction heating device and move each stacking mold out of the hollow cavity after the induction heating is completed;
wherein the loading and unloading device comprises:
a support;
a vertical displacement adjusting element which is arranged on the support;
a base plate which is connected to the vertical displacement adjusting element and driven by the vertical displacement adjusting element to move in the vertical direction;
a horizontal movable plate which is arranged on the base plate, the horizontal movable plate being configured to slidably move in the horizontal direction relative to the base plate; and
a stacking mold seat which is arranged on the horizontal movable plate for receiving a stacking mold.
