Description
Technical Field
The utility model relates to an injection mold technical field especially relates to a mouth of a river bullet needle structure of three-plate mold.
Background
The mold is an important equipment indispensable in injection molding. Injection molding is a method in which a hot-melt plastic material is injected into a closed molding space having a desired shape in a mold at a high speed, and after the plastic material is cooled and solidified, the mold is opened to eject the solidified plastic work to obtain a molded product. The injection molding method has the characteristics of low molding cost, short molding period, simple molding process, easiness in molding of plastic products with complex shapes and the like, so that the injection molding method is very commonly applied to the field of plastic product manufacturing.
In a three-plate mold, when the mold is produced, the water gap can be stuck on the back-off of the water gap crochet hook and is not easy to automatically drop due to the particularity of the water gap. Therefore, automatic production cannot be realized due to the need of a manual water intake, labor cost is wasted, and the operation risk of workers is increased.
