Mold Identification Mark Readability Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for engraving identification marks on molds for casting are troublesome, often resulting in unreadable marks, leading to defective casting products due to difficulties in adjusting engraving conditions, which complicates tracing production history and increases the rate of defective products.
Innovation Solution
A mold information management system that uses a processor to determine the readability of identification marks based on image or profile data captured from the mold surface and associates the marks with mold history and properties, ensuring only readable marks are used for casting, thereby reducing the occurrence of defective products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If laser engraving is used to create identification marks on molds, then the marks can be directly engraved without attaching marking materials, but the engraving conditions are difficult to adjust resulting in collapsed marks or insufficient depth
Solution Approach 1:
The system captures images of the engraved identification marks and automatically evaluates their quality (readability, depth, clarity). This feedback mechanism allows real-time monitoring of engraving quality and enables adjustment of engraving parameters to maintain consistent mark quality without manual inspection
Solution Approach 2:
The patent replaces manual attachment of marking materials with automated laser engraving. The laser marking device directly engraves identification marks onto the mold surface, eliminating the need for mechanical attachment processes and reducing human intervention while maintaining mark precision through automated control
2Reliability
If identification marks are engraved on molds, then production history can be traced, but unreadable marks lead to defective casting products
Solution Approach 1:
The system performs preliminary evaluation of identification mark quality immediately after engraving, before the mold is used for casting. By checking mark readability in advance, the system prevents defective marks from causing defective casting products, thereby maintaining traceability while eliminating the harmful effect of unreadable marks
Solution Approach 2:
The automatic image capture and evaluation system provides continuous feedback on mark quality, enabling real-time detection of unreadable or defective marks. This feedback loop ensures that only molds with clear, readable identification marks proceed to casting, maintaining both traceability and product quality
3Loss of information
If marking materials are attached to molding surfaces, then management codes can be formed, but the process is troublesome and time-consuming
Solution Approach 1:
The patent replaces the mechanical process of attaching marking materials with automated laser engraving. The laser directly creates identification marks on the mold surface through ablation, eliminating the time-consuming attachment process while preserving all necessary identification information for traceability
Solution Approach 2:
The mold surface itself serves as the medium for the identification mark through laser engraving. The mark is created directly on the mold without requiring external marking materials, making the mold self-sufficient for identification purposes and eliminating the need for separate marking material attachment

AI summary
An aspect of the present invention provides a mold information management device, a casting system, and a mold information management method each of which makes it possible to reduce a rate of occurrence of defective casting products due to unreadable identification marks, as compared to a conventional rate of the occurrence. A mold information management device includes at least one processor, the processor carrying out: a determination process for determining whether an identification mark is good or not, on the basis of image data or profile data obtained by capturing an image of or scanning a surface of a mold on which the identification mark is engraved; and an associating process for associating the identification mark with information on at least one of history and properties of the mold, in a case where the identification mark has been determined to be good in the determination process.
