The definition of mold processing mainly refers to the processing of molding and blank making tools. The steel plate is placed between the upper and lower molds. The hydraulic press workmanship realizes the forming of materials. When the press is opened, the workpiece determined by the mold shape can be obtained, and the corresponding waste can be removed to achieve twice the result with half the effort.
1. Basic characteristics of mold processing
1. Mold processing has relatively high requirements for processing technology. It is generally composed of a concave die, a mould and a mold frame. Of course, many parts can also be spliced into a combined module.
2. Some products with relatively complex shapes, such as aircraft parts, household appliances, etc., have multiple curved surfaces on the surface. Such mold processing is more complicated, and the mold cavity surface is uneven, and it may even require mathematical calculations to process the curved surface.
3. The characteristic of mold processing is that it is small in batches. Production is not mass-produced. In many cases, it is just one piece of production.
4. There are many mold processing steps, and various processes such as boring, glue, and drilling may be used during the processing process.
5. For repetitive production molds, they will have a certain lifespan when used. When the use of the mold exceeds its life, a new mold must be replaced, which will cause the mold production to be repetitive.
6. For the production of imitation processing molds, not only does there be no patterns, but there is no data. This requires imitation processing based on actual objects, which is relatively difficult. It is also required that the imitation accuracy meets certain requirements and does not deform during use.
7. During the mold processing process, you must pay attention to quality when choosing materials. In the mold production process with higher hardness, high-quality alloy steel will be used, which is especially true for molds with high life. This material is relatively strict in both the forging of blanks, processing and heat treatment.
In this way, many basic characteristics need to be followed in the mold processing process. When choosing a machine tool, you must meet the corresponding processing needs so that better molds can be produced.
