Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a nozzle cleaning device for an injection molding machine. Background Art

[0002] Plastic injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal, and all-electric types. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, and make it eject and fill the mold cavity. It is mainly used for plastic injection molding, plastic tables, chairs, cabinets and other items.

[0003] The nozzle of the existing injection molding machine will have a lot of raw materials left after working for a long time, and a large amount of solidified plastic will adhere to the inner wall of the nozzle, which will make the nozzle space smaller after long-term use and eventually become blocked, affecting the subsequent injection molding and requiring cleaning.
