The tire curing press plays a pivotal role in the tire manufacturing process, as its performance directly impacts tire quality and production efficiency. With the increasing maturity of electromagnetic heating technology, numerous tire manufacturing and curing press enterprises have begun integrating this technology into tire curing presses to enhance vulcanization efficiency and reduce energy consumption. However, many older equipment models were originally designed without considering the application requirements of electromagnetic heating technology, rendering them incompatible with this method. This study delves into the retrofitting issues of external temperature electromagnetic heating for full-steel mechanical tire curing presses, proposing a practical retrofit design solution. It effectively addresses challenges such as the layout of heating coils on the upper plate and the detachability of mold heating covers. The findings of this research provide valuable guidance for the retrofitting and upgrading of equipment in tire manufacturing enterprises.
