MOLD APPARATUS HAVING CONJUNCTION STRUCTURE MADE BY DIFFERENT MATERIALS

摘要

PURPOSE: A mold having the joint structure made of different materials is provided to improve the productivity by rapidly controlling a temperature of a mold and to prevent costs from increasing. CONSTITUTION: A mold having the joint structure made of different materials comprises an upper mold (10) forming a cavity by combing the different materials and a lower mold (20). At least one among the upper mold or the lower mold is formed as the different materials in which a heat transfer rate is different are combined. The material in which the heat transfer rate is high is arranged at a part surrounding the cavity.
