Tracing method for cast production information and prefix of tracing characteristics of casting production information

Abstract

The invention discloses a tracing method for cast production information. The inner wall of the cavity of a mold is provided with concave or convex tracing characteristics representing the cast production information; the tracing characteristics comprise the mold code characteristic representing the mold, the casting date characteristic representing the casting date, the shift characteristic representing the casting shift, and the casting operator code characteristic representing a casting worker; during casting, the worker on duty takes the mold marked with the corresponding mold code characteristic, the casting date characteristic, the shift characteristic and the casting operator code characteristic to cast a part; and after the part is cast and molded, corresponding imprints of the various tracing characteristics are formed on the part, and the four pieces of production information including the mold used during casting of the casting part, the casting date, the casting shift and the casting worker can be determined according to the tracing characteristics recorded on the casting part. By means of the method, the production information of the casting part can be traced so that the reason for the quality problem of the casting part can be found.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a method for tracing casting production information of parts and the features used for tracing the production information. Background technique [0002] Casting is a kind of metal thermal processing technology mastered by human beings earlier. It occupies an extremely important position in the history of human industry and has a history of about 6,000 years. China has entered the heyday of bronze castings between 1700 BC and 1000 BC, and the craftsmanship has reached a very high level. Casting is a method in which liquid metal is poured into a casting cavity suitable for the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly a metal that is originally solid but can be heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal o...

Problems solved by technology

However, due to the huge batch size of parts casting, the complexity of the process, and the wide range of personnel involved, it is difficult to analyze the quality problems of parts from many possible factors; for example, a certain pair of molds, a certain date, a certain shift, The production information of a certain worker may become the traceability point of the quality problem. At present, it is necessary to find out the cause of the quality problem from the castings that have been formed or have been put into storage or even used, analyze the problem back to the source, and find the solution to the problem. It is very difficult to formulate corresponding solutions because the quality of castings at this time is difficult to trace after leaving the production site
