Problems solved by technology

[0002] Two-color injection molding, two-shot molding mainly uses two material tubes of two-color molding machine and two sets of molds to make two-color products through two moldings in sequence. Two-color injection molding has now been widely used in electronic products, electric tools, medical products, home appliances, and toys. In almost all plastic fields, the production and molding of two-color molds and the research and development of two-color multi-color injection molding machines and two-color injection molding raw materials have also developed rapidly. From the characteristics and applications of double-material co-injection molding, it can be seen that the future will gradually replace traditional injection molding. The trend of the molding process, the innovative injection molding technology not only improves the precision of the injection molding process, provides difficult process technology, but also expands the scope of the injection molding process. Innovative injection equipment and processes are sufficient to cope with more and more diverse Due to the relatively simple work of most of the existing injection molding devices, the waste rate of the plastic products of the injection molding device is high, and the operation of the injection molding device for a long time increases the displacement of the drive device. In some cases, the plasticized product cannot be dropped in time for recycling, which has brought certain adverse effects to the actual use, so it needs to be improved
