Mold processing refers to the processing of forming and blanking tools, in addition to shearing dies and die-cutting dies. What are the characteristics of these molds? I will explain it to you today.
1. Generally, there are molds composed of concave film, convex mold and film frame, and the control accuracy is higher. Some may also be composed of multiple pieces. Therefore, the combination of upper and lower molds, the combination of inserts and cavities, and the assembly of modules require high machining precision.
2. Small batches of molds are not mass produced during production, but only one pair is produced in most cases.
3. The use of molds has a long life. When a pair of molds exceeds its life, the mold should be replaced in time, so the mold production process has a certain degree of repeatability.
4. Various processes such as milling, boring, drilling, reaming and tapping are also used in regular mold processing.
5. The main material of the mold is high-quality alloy steel. Some molds with long service life are often made of Crl2, CrWMn and other ledeburite steels. The production and processing of this material is very strict, so the processing technology cannot be ignored. Deformation is also an aspect that needs to be taken seriously in processing. To sum up, when choosing an airport, it is necessary to meet the processing conditions as much as possible, such as strong functionality, high precision of the machine tool, good rigidity, thermal stability and anti-type functions.
6. Some surface shapes are composed of multiple curved surfaces, such as automobile covering parts, airplanes, parts, toys, household appliances, etc. Therefore, the mold cavity is easy to be complicated, and some need to be processed by mathematical calculations.
7. Some molds have neither patterns nor data in the production process, and can only be imitated by the real object, which requires high imitation accuracy and no deformation.
The introduction of mold processing characteristics is here today.characteristics of mold processing
