the knowledge of mold processing

The mold processing industry is developing rapidly. Now many things are made by mold processing. This article will take you to understand its characteristics.

1. The precision of the mold processing technology can be high. The mold is generally composed of a concave mold, a convex mold and a mold base system, and some may also be a multi-piece design module. Therefore, the combination of the upper and lower molds, the combination of inserts and cavities, and the assembly of module functions require high processing method accuracy. The dimensional calculation accuracy of precision machinery molds often reaches the μm level.

2. The shape is complex. Some products, such as car panels, aircraft parts, toys, household appliances, etc., have surface shapes composed of various curved surfaces. Therefore, the surface of the mold cavity is very complicated. Some surfaces must be processed mathematically.

3. The production of batches of small molds is not mass production. In many cases, only one pair is produced.

4. Multiple processes. In the mold processing, you always need to use many different processes such as milling, boring, drilling, reaming and tapping.

5. Long service life of repeated production molds.

6. Copy processing. Sometimes there is no pattern or data in mold production. Copy processing should be performed according to the object. This requires high simulation accuracy and no distortion.

7. The mold material has excellent performance and high hardness. The main material of the mold is made of high-quality alloy steel, especially the long-life mold. This kind of steel has strict requirements from blank forging, processing to heat treatment. Therefore, the processing technology of the preparation cannot be ignored, and the heat treatment deformation is also a problem that needs to be solved seriously in the processing.

According to the analysis of the above-mentioned many development characteristics, the selection of machine tools should not meet the processing technology requirements of enterprises as much as possible. For example, the function of the CNC control system should be strong, the precision of the machine tool should be high, the rigidity should be good, the thermal stability should be good, and it has the function of profiling. the knowledge of mold processing
