What are the injection mold runner turning technologies?

Injection mold flow channel turnover technical requirements specification refers to the design and manufacturing process of injection mold, the original flow channel facing the outside of the mold to the inside of the mold a technical requirement specification. The application of this technology can improve the appearance quality of the product, reduce defects, and facilitate the cooling and ejection of the mold.

The following are five aspects to introduce the injection mold flow channel turnover technical requirements:

(1) Runner design: The flow channel is the channel of conveying molten plastic in injection mold, and its design has an important influence on product quality and production efficiency. The size, shape and position of the runner should be considered when the runner is turned over. Reasonable flow path design can ensure uniform plastic filling, avoid bubbles and thermal stress and other problems. (2) Mold structure: The structure of the injection mold needs to adapt to the requirements of the flow channel turnover technology. The mold needs to be designed to be detachable or rotatable in order to perform the runner turnover operation. At the same time, the cooling system and ejector mechanism of the mold also need to be adjusted accordingly to adapt to the layout of the flow channel after flipping. (3) Material selection: When carrying out the runner turnover technology, it is necessary to choose the appropriate mold material. The mold material needs to have sufficient strength and wear resistance to withstand the pressure and friction caused by the turnover of the runner. Commonly used mold materials include high-quality steel and wear-resistant alloys. (4) Processing technology: Runner turning technology requires a series of processing techniques. The first is mold processing, including turning, milling, grinding and other processes to achieve the design requirements of the flow channel. The second is the mold assembly, which needs to assemble the various parts in accordance with the design requirements, and ensure the correct layout after the flow channel is flipped. (5) Runner debugging: After the completion of the mold manufacturing, it is necessary to carry out the debugging work of the flow channel turnover. In the debugging process, it is necessary to check the flow channel patency, plastic filling, product appearance quality and other indicators to ensure the effective application of the flow channel turnover technology. To sum up, the injection mold runner turnover technology is an important technology to improve product quality and production efficiency. In the process of runner turnover, it is necessary to consider the requirements of runner design, mold structure, material selection, processing technology and runner debugging. The appearance quality of injection molding products can be improved, defects can be reduced and production efficiency can be increased by reasonable application of runner turning technology.
