Description

Technical Field

[0001] The utility model relates to the technical field of marking and positioning, in particular to a rotating body mold marking device. Background Art

[0002] A body of revolution mold is a mold used to manufacture parts with rotationally symmetrical shapes. It plays an important role in industrial production and is widely used in the production of various plastic products, such as toys, packaging materials, electronic parts, automotive parts, etc.

[0003] In the process of manufacturing rotating body molds, it is crucial to accurately draw marking lines on horizontal planes at different heights to meet the verification work requirements in the subsequent production process. The current marking method is that the operator uses a steel tape measure or a steel ruler to mark the marking area on the rotating body mold one by one. This method has certain limitations in actual operation. It is difficult to complete by one person and requires the cooperation of auxiliary personnel. The process of manually drawing marking lines is not only time-consuming but also labor-intensive. It is also difficult to ensure the high accuracy and straightness of the marking lines, which in turn affects the processing quality and production efficiency of the subsequent molds.

[0004] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of implication that the information constitutes the prior art known to those skilled in the art.
