This study is intended to clarify thermal responses and thermoelastic behavior of metal molds for the injection molding subjected to Induction-heating. Assuming a conducting circular plate as a model for the analysis of metal molds, we consider that uniform magnetic flux changes in time in the thickness direction of the circular plate. Analytical solutions of temperature change and the associated stresses in the plate subjected to eddy current loss and Lorentz force are derived under a plane axisymmetrical condition. Numerical calculation is performed, and eddy current loss and Lorentz force are evaluated, then spacial distributions and time evolutions of temperature change, thermal stresses are examined. A heating-cooling method is discussed in order to improve defects in resins during injection molding.
