Description

Technical Field

[0001] The utility model relates to the field of injection molding production, in particular to a stirring hopper for injection molding. Background Art

[0002] Injection molding machine is also known as injection molding machine or injection machine. It 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 and apply high pressure to the molten plastic to make it eject and fill the mold cavity. At present, single-color plastic particles can be directly added to the injection molding machine for use, but two-color or multi-color plastic particles need to be mixed and stirred before they can be added to the injection molding machine for use. Therefore, a hopper with a stirring mechanism will be installed on the extrusion device of this type of injection molding machine. For example, the announcement number: CN219055131U discloses a stirring hopper for injection molding. The structure in this application is relatively complicated, which is inconvenient for the staff to inspect and clean, and it is easy to cause impurities to remain in the gaps of the parts, affecting the next use.
