Abstract

The invention discloses a stamping die surface phosphating processing method, and relates to the technical field of mold processing. The stamping die surface phosphating processing method includes thefollowing steps of polishing, heating, phosphating, twice soaking and twice drying processing and pressurizing processing. By means of the stamping die surface phosphating processing method, a uniform and compact phosphating film can be formed on the surface of a stamping die, the surface of the stamping die can be better protected, and the processed stamping die has excellent high-temperature corrosion-resistant performance.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of mold treatment, and in particular relates to a phosphating treatment method for the surface of a stamping mold. [0003] 【Background technique】 [0004] The so-called molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, casting, forming, smelting, stamping, stretching and other methods to obtain the required products. Stamping die is a special process equipment that applies pressure to the material to cause separation or plastic deformation to obtain the required parts or products. Due to the generally large production batches of stamping parts and the high working temperature of stamping, the surface of the stamping die often suffers from wear, oxidation, or oil contamination, which leads to the quality and appearance of the stamped workpieces not up to standard. It is of great significance to effectively treat the surface to reduce the ...
