Description

Technical Field

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

[0002] 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 and apply high pressure to the molten plastic to make it eject and fill the mold cavity. During the production process of the injection molding machine, a certain amount of glue must be melted before injection molding and stored in the storage device for use by the injection molding machine.

[0003] Most of the storage devices used in existing injection molding machines are not convenient for uniformly stirring the materials when storing them. When the materials are mixed in the storage device, some of the materials settle at the bottom and the materials above cannot be uniformly stirred, making the concentration of the materials above different from that of the materials below, resulting in poor effects due to the concentration when the materials are used. Therefore, we propose an injection molding storage device for injection molding machines. Utility Model Content
