1. There are some products with complex shapes, such as vehicle covers Airport parts Small toys The surface of electrical products is composed of various inclined surfaces, some of which must be solved using computational power.

2. High precision requirements for processing: A mold is generally composed of a cavity The mold base and mold base are composed, and some may also be multiple splicing control modules. There's up The composition of the upper mold, the composition of the insert and the concave mold, and the splicing in the middle of the control module are all required to have high machining accuracy. The specification accuracy of precision molds usually reaches the μ m level.

3. There are multiple processes involved in precision mold processing: milling is always used in mold processing Boring Drill There are various technological processes such as hinge and screw thread tapping.

4. Repeatability for construction and production: The application of molds has a service life. When a mold is used beyond its service life, it needs to be replaced with a new mold, so the manufacturing of molds usually has repeatability.

5. Large batch small: The production and manufacturing of molds is not a large-scale production, and in many cases, only one is usually produced and manufactured.

6. Imitation processing: Sometimes in mold production and manufacturing, there are no sample drawings or data information, and imitation processing needs to be carried out based on the entity. This requires high imitation accuracy and no deformation.

7. The raw materials for molds are excellent and have high strength. The specific raw materials for molds are mostly made of high-quality carbon steel, especially for molds with high service life, which are often made of martensitic steels such as Crl2 and CrWMn. This type of stainless steel plate is forged from rough grains Strict management is implemented for both processing and heat treatment processes. Therefore, the formulation of processing technology cannot be ignored, and deformation in heat treatment process is also a difficult problem that needs to be carefully completed during processing.

based on many of the above characteristics, it is advisable to meet the processing requirements as much as possible when using equipment. If the function of the CNC machine tool is good, the precision of the CNC lathe should be high, the rigidity should be good, the heat resistance should be good, and it should have the function of imitation.
