Method for engraving character or graphics on metal mold

Abstract

The invention discloses a method for engraving a character or a graphics on a metal mold. The method comprises the following steps: firstly, placing the metal mold on a three-dimensional work table ofa laser engraving machine, and adjusting the metal mould to a corresponding engraving position; secondly, making a character or a graphics to be engraved and adjusting the parameters of the laser engraving machine; and thirdly, scanning layer by layer to reach a required depth. The method for engraving the character or the graphics on the metal mold can solve the problems of the complex flow of the conventional CNC or EDM and liquid medicine corrosion process, simplify the structure design of the mould without generating mechanical extrusion or stress in the process and has the advantages ofsmall heat-affected region, fine process, no deformation of a workpiece, high processing efficiency, low cost and easy operation without pollution.

Description

Technical field [0001] The invention relates to the processing of plastic and stamping metal molds, in particular to a method for engraving characters or graphics on plastic and stamping molds with laser. Background technique [0002] Plastic and stamping products are the products of modern technology, and they are increasingly used in general livelihood products. In recent years, with the rapid development of industry, the application range of plastics and stamping products is also expanding, such as: household appliances, instrumentation, construction equipment, automobile industry, daily hardware and other fields, plastics and stamping products account for The proportion is increasing rapidly. Corresponding metal molds are also increasing day by day. In response to the above phenomenon, we directly engrave merchants' trademarks, various requirements, production time or product grades and other content signs on the molds to obtain corresponding information on the products.

AI Technical Summary

Problems solved by technology

CNG processing has no right angle or acute angle due to the tool, and the thin-walled part is easy to deform

Moreover, molds with high hardness such as HRC60 or above are difficult to machine; the EDM production process is complicated, and the corresponding electrodes are first made, and then EDM electric discharge machining is performed, which is costly and long-term

The corrosion method is rarely used because the position accuracy and depth cannot meet the high-precision requirements, and characters with a height less than 0.6MM cannot be completed.
