Background In the prior art, the mold management of a precise sheet metal workshop is mostly realized based on an informationized warehousing system, the mold is usually marked by a bar code or an RFID, and the warehousing, the ex-warehouse and the inventory recording of the mold are completed by combining a WMS system. Meanwhile, the system classifies and stores the molds according to the preset library position rules, and realizes mold scheduling and use record management under the drive of production tasks through data interaction with an MES or ERP system. Part of the system also introduces a simple inventory early warning or frequency of use statistics function for assisting management personnel in making a die configuration decision. However, in practical applications, for example, in a precise sheet metal workshop where a large number of special-shaped molds exist and the size difference is significant, different molds have different requirements on storage space and bearing modes. The existing system generally only carries out library position allocation by codes or categories, and lacks dynamic constraint on the matching relation between the geometric dimension of the die and the space of the library position, so that operators need to manually judge whether the die can be placed in a designated library position during actual warehousing, and even the condition that the large-size die occupies a plurality of standard library positions or is forcibly placed to cause taking and placing interference occurs. For example, after some strip bending molds are arranged to a standard square goods space, the operation can be completed only by removing the adjacent molds when taking out, so that unnecessary carrying steps are added, and collision damage can be caused to the peripheral molds.
