In the production process of casting molds, technical inspection is very important. Casting mold manufacturing generally belongs to single-piece production, and the materials are expensive. In order to eliminate waste, reduce costs, and improve the quality of individual parts and component assembly quality, it must be strictly inspected according to the drawings during the production process to meet the required technical standards, so as to improve the accuracy and durability of the casting mold. In production, the technical inspection content of casting molds mainly includes the following aspects:

1) Quality inspection of casting mold materials;

2) Inspection of the quality of casting mold cores and cavities;

3) Appearance quality inspection after casting mold assembly;

4) Detection of shape and position errors of casting mold processing parts;

5) Dimensional accuracy measurement of casting mold processing parts;

6) Surface quality inspection of casting mold parts;

7) Non-destructive testing of the intrinsic quality of casting mold parts;
