What are the common methods of precision mold processing?
No matter what kind of precision mechanical production equipment is manufactured, it is indispensable. The whole process of precision machine manufacturing includes: CNC machining center cutting, slow wire cutting, wire cutting, cutting, milling, precision measurement, automation technology, etc.
1. CNC cutting production and processing
The main cavity and surface of the injection mold are cut by CNC machining center. The rapid development of the rubber mold manufacturing industry is mainly due to the independent innovation of CNC machining center cutting technology.
2. Slow wire cutting production and processing
Slow wire cutting technology is mainly used to process 2, 3D standard surface parts, such as various mold shells, injection molds and unmetallurgical mold parts. Among them, the production and processing of metal molds accounts for a large percentage. The production and processing of many high-precision holes such as metal mold punching dies, punching fixed plates, cavities and reversing plates is the core technology that cannot be missing from slow wire cutting. In the production of plastic molds, the applications of inserting, top, inclined top holes, clear viewing angles and rollers are commonly used. Generally speaking, the machining accuracy cannot be compared with that of metal molds.
Slow-moving wire is a highly sophisticated production method. The machining accuracy of advanced machine tools is less than 3μm, and the surface roughness can reach 0.05μm. At this stage, automatic production line laser cutting of 0.02-0.03_ electrode wire can be done. The drilling efficiency can be up to about 200mm_2/min.
3. Processing grinder
CNC grinding machine is a kind of machine tool for deep processing of the surface of parts. Small and medium-sized tool grinders are mainly used for the production and processing of small and medium-sized mold parts, such as high-precision inserts, precision machinery manufacturing, rollers, etc. Large and medium-sized water mills are often used in the production and processing of large and medium-sized molds. At this stage, fast grinding wheels and operating tables have become a common development trend. Due to the use of professional components such as linear slides, servo motors, and hydraulic press screws, the speed ratio of the grinding wheel has been greatly developed, and the refurbishment technology of the grinding wheel has also been greatly developed.
4. Processing center
The mold shell production workshop is also a common machining center. Its production category is the whole gyro picture part. Due to the extreme development trend of CNC machining technology, it is easier to complete complicated rotations according to the programming, and CNC lathes can replace special tools by themselves to further improve production efficiency. With the continuous improvement of the machining accuracy and production technology of the machining center, there is even a development trend of out-feed grinding. It is often used to process components such as round inserts, supports, and accurately positioned rings in molds. Can be widely used in signature pen molds, water bottle molds, etc. In fact, the role of a good machining center will no longer be limited to “vehicles”. This is a composite CNC lathe for cutting and turning. A more complex and more complete process can even be solved at one time.
5. Accurate measurement
High-precision measurement is very important for the data drawing involved in the original design of the mold shell, the accurate measurement of mold manufacturing, and the accurate measurement of the mold shell repair in the middle and later stages. The role of high-precision measuring equipment is very important.
Fast clamping of mobile phone positioning systems and automation technology.
Mold parts often require various processes to manufacture. During this phase, the parts are constantly clamped and adjusted, which takes a lot of time. CNC lathes are still vacant, and the production capacity of expensive machinery is not being used flexibly. With the increasingly fierce market competition in the manufacturing industry. Production cuts are a growing trend. The stability and accuracy standard management system selected by foreign mold and fixture manufacturers has completed the exchange of unified standards for cutting, cold rolling, precision measurement, and wire EDM. CNC lathes for quick electrical installation and calibration in under a minute. The repeated positioning accuracy is within 3 microns, which reduces the setting time and further improves the actual running time of the CNC lathe. These have proven necessary for modern manufacturing.
The above is about the relevant content of precision mold processing. In fact, the process of mold processing and material selection are very important, and the design methods and processing procedures required by different molds will also be different, but it is worth considering that no matter what kind Mold and processing technology need to be continuously improved. Hope the above content is helpful to readers.
