The invention relates to an informatization management system and method for warehousing, storage and ex-warehouse of tyre mold movable blocks, particularly intelligentization management of the movable blocks is precisely realized through control and management of two-dimensional codes and a PLC of the system. A rotary warehouse storage system for mold accessories comprises a three-dimensional warehouse, chain wheels are arranged in the center of the three-dimensional warehouse, a plurality of rows of case buckets are arranged in the extension direction of the chain wheels at equal intervals, each case bucket is provided with three separated layers, each separated layer is provided with a storage location bar code, the interior of each layer is provided with the movable blocks, and the movable blocks are equipped with two-dimensional codes; the three-dimensional warehouse is provided with an opening in the extension direction of the chain wheels, an operation platform is arranged outside the three-dimensional warehouse, and the location of the operation platform is level to the lowest end of the opening. The rotary warehouse storage system further comprises an electronic control system. Working efficiency is improved, in traditional management modes, it takes a long time to find movable blocks, the occurrence that the movable blocks cannot be found is frequent, but at present, automatic ex-warehouse of the movable blocks can be achieved in a few minutes.
