A well-known sand core mold manufacturer in China hopes to quickly obtain the 3D appearance data of the original sand core mold through a three-dimensional scanner, and compare it with the original digital model diagram to obtain a sand core mold inspection analysis report and check the quality of the sand core mold data. Qualified, to produce sand core molds to speed up the development and production of new products.

Practical problem

1. The sand core mold has a complex shape and a small body, with many concave and convex surfaces, many holes and other characteristics, and the inability to spray powder brings great difficulty to the scanning work.
2. Using general measurement methods (three-coordinate, two-dimensional, caliper, etc.), only a small part of the data of the sand core model can be obtained, and the water chestnut part cannot be measured, resulting in incomplete data volume, and the secondary design of the sand core model cannot be carried out. Improved.

Holon solutions

The sand core mold is carried out at the same time as the later modeling and manufacturing, and the three-dimensional model of the sand core mold is completed. Sand core molds need to make stamping molds and injection molds. After the different molds are completed, test molds, assembly, and modification of the respective molds are performed. This process requires the cooperation of sand core molds and post-production data, that is to say, there are two uncertainties. Factors that increase the modification cycle and manufacturing costs.

Holon 3D technical engineers use the industrial 3D scanner HL-3DX+ to quickly scan the sand core model to obtain high-density point cloud data. Combined with professional 3D data design software, the point cloud data is converted into triangular mesh surface data. Comparing and analyzing the sand core modulus, it can quickly detect the errors and defects of the sand core model. Compared with traditional detection methods, Hualang 3D effectively solves the problems of the enterprise and improves the production efficiency of the enterprise.
