3D design and standardization of molds
Modern manufacturing is the basic industry that reflects the country's comprehensive national strength. Molds are the core technical equipment for the production of machine tools, automobiles, railway locomotives and other mechanical products, aerospace and navigation products, modern electrical products, information products, household electrical appliances, building materials, medical equipment and other products in the modern manufacturing industry. The mold needs to be specially designed and manufactured, and it is produced in a single piece.

The future development direction of mold manufacturing
With the development of economic globalization, the market situation in China is constantly changing. Developed countries propose "re-industrialization" to regain the competitive advantage of the manufacturing industry with artificial intelligence, robots and digital manufacturing. It is difficult for Chinese mold companies to continue to rely on low-cost competitiveness. Moreover, molds are widely used in various fields, and there are more and more requirements for mold equipment. Therefore, mold manufacturing needs technological innovation, and it is an inevitable trend to develop towards standardized unmanned processing.

Affect the accuracy of injection molds during processing
Refers to the consistency and degree of the actual working size of the processed part and the dimensional tolerance of the part. Dimensional accuracy is controlled by dimensional tolerances. Dimensional tolerance is the allowable variation in part size during cutting. When the basic dimensions are the same, the smaller the dimensional tolerance, the higher the dimensional accuracy.

How to control the temperature of plastic processing molds?
When designing a plastic processing mold, it is necessary to control the temperature of the mold product. When the designed mold injection weight is small and the mold size is large, the heat transfer in the mold structure is very important. The flow path of the mold coolant should be stable, and try not to use quick connectors, otherwise the flow of the mold coolant may be blocked.

The temperature that the injection mold needs to pay attention to when molding
Injection molds are relatively common plastic parts in factories. In order to make an injection mold, the temperature needs to be controlled, followed by the injection pressure and time. The birth of a good injection mold, in the manufacturing process, this All three points need to be taken into consideration, and all of them need to be done well.

The most important part of the flash is the processing of the parting surface, that is, between the movable mold and the static mold, the sliding part of the slider, the matching gap of the insert, the hole of the ejector rod, etc. Excessive flash burrs are formed on it.

The working principle of injection molding machine
Injection molding is a cyclic process, each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and taking out. After the plastic parts are taken out, the mold is closed again for the next cycle. The operation items of injection molding machine include control keyboard operation, electrical control system operation and hydraulic system operation. The selection of injection process action, feeding action, injection pressure, injection speed, ejection type, temperature monitoring of each section of the barrel, adjustment of injection pressure and back pressure, etc. are carried out respectively.

The main and most common causes of glitches are as follows
Whether the parting surface is carefully researched or not can directly lead to the existence of flash of the product; this depends on the technology of the mold fitter. Mold research and development is a delicate job, which tests the patience and skill of the mold fitter. This is also one of the most direct reasons for the product to take off, so when we found out that the mold was not in place, the solution was to re-install the mold clamping machine.

How to deal with gloss defects on the surface of plastic injection molds?
The following are the causes and solutions of the surface gloss defects of plastic injection molding molds, hoping to help you. 1. The mold finish is poor, the surface of the cavity has rust, etc., and the mold exhaust is poor. 2. The gating system of the mold is defective, the cold well should be enlarged, the runner, the polishing main runner, the runner and the gate should be enlarged. 3. The material temperature and mold temperature are low. If necessary, the local heating method of the gate can be used. 4. The processing pressure is too low, the speed is too slow, the injection time is insufficient, and the back pressure is insufficient, resulting in poor compactness and dark surface. 5. The plastic should be fully plasticized, but the degradation of the material should be prevented, the heating should be stable, and the cooling should be sufficient, especially for thick-walled ones. 6. Prevent cold material from entering the workpiece, and use self-locking springs or reduce nozzle temperature if necessary. 7. Too many recycled materials are used, the quality of plastic or colorant is poor, mixed with water vapor or other impurities, and the quality of the lubricant used is poor. 8. The clamping force should be sufficient.
