Wax mould casting production line data chain construction method and system

The invention is suitable for the technical field of data chains, and particularly relates to a wax mould casting production line data chain construction method and system, and the method comprises the steps: obtaining CAX models of wax mould casting production line equipment and workpieces, constructing and storing a physical entity model, and constructing a knowledge graph; entities, attributes, relation integration and connection multi-source heterogeneous data in the knowledge graph are represented as a unified data description format, and a data chain database is constructed; importing the process parameters and the equipment management data into the knowledge graph, and constructing an association relationship; and setting a data interface for the data link database. The data link constructed by the invention uniformly manages key process parameter information, dimensional deviation of a workpiece, three-dimensional model information of equipment and the like without distortion, can provide authoritativ
