Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding equipment, in particular to a feeding mechanism of injection molding equipment. 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.

[0003] In the process of using the existing feeding mechanism of injection molding equipment, when performing the feeding and conveying work, the material at the bottom of the hopper melts because the material port is too close to the heating ring. After melting, the material agglomerates, making it difficult for the mechanism to unload the material, resulting in a decrease in the working efficiency of the mechanism. Therefore, we propose a feeding mechanism for injection molding equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a feeding mechanism of an injection molding device. By setting a heat insulation component, specifically, the heat insulation component is installed at the bottom of the feeding mechanism shell near the heating structure of the injection molding device. The polyurethane foam board contained in the heat insulation component can effectively insulate the heating structure of the injection molding device. The steel plate contained in the heat insulation component is wrapped on the outer surface of the polyurethane foam board, which can further help with heat insulation and prevent the polyurethane foam board from overheating and spontaneous combustion, avoiding the occurrence of material solidification caused by the melting of the material at the bottom of the hopper, improving the working efficiency of the equipment, and reducing the situation where the equipment unloads the material too slowly due to the solidification of the material. The problem that the feeding mechanism of the existing injection molding equipment melts the material at the bottom of the hopper during the feeding and conveying work due to the close proximity of the material port and the heating ring, and the material agglomerates after melting, making it difficult for the mechanism to unload the material, resulting in reduced working efficiency of the mechanism.
