Description

Technical Field

[0001] The utility model mainly relates to the technical field of mold detection, in particular to a casting mold flatness detection mechanism. Background Art

[0002] Flatness testing of molds is a key step to ensure mold quality, extend service life, ensure product accuracy and meet assembly and matching requirements. Through flatness testing, small fluctuations or defects on the mold surface can be discovered and repaired in time, and wear and deformation caused by flatness errors can be prevented. This ensures that the accuracy and stability of the mold meet production requirements. At the same time, flatness testing is also a necessary measure to meet relevant national standards and requirements, which helps to improve the overall performance and reliability of the mold and ensure that the products produced are of high precision and good quality.

[0003] The cylindrical mold not only needs to be tested for flatness on the horizontal surface at the bottom, but also on the curved surface of the side wall. However, the existing flatness detection mechanism cannot meet the detection of curved and horizontal surfaces at the same time. Different detection structures are needed to detect them respectively, so the overall detection efficiency is low. Utility Model Content
