Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a hopper drying 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 ejected and fill the mold cavity. However, we have found in real life that when the existing injection molding machine hopper dries the plastic particles, it only heats the wind generated by the fan, so that the hot air dries the plastic particles in the hopper. However, in this way, during the drying process, the plastic particles in the injection molding machine hopper cannot be dried by the hot air in all directions, and a large amount of plastic particles are accumulated, which limits the drying efficiency of the fan. For this reason, we propose an injection molding machine hopper drying device. Utility Model Content
