Technical Field

The utility model relates to the technical field of injection molds, in particular to an injection mold with an automatic cleaning function for an injection port.

Background Art

Injection mold is also called injection molding. It is a molding method of injection and molding. The advantages of injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product.
