Feeding device for injection molding machine

Abstract

The utility model proposes a feeding device for an injection molding machine, which comprises a storage component composed of a storage barrel, a stirring component composed of a stirring motor and a stirring screw, a conveying component composed of a conveying motor and a conveying screw, a heating component composed of a heating cover and an electric heating plate, and a heat preservation component composed of a heat preservation plate. The utility model has the advantages that, by arranging multiple sections of a heating cover and an electric heating plate, different heating temperatures are adopted for different barrel sections. When a higher temperature is required for heating, the electric heating plate of the section adopts a higher temperature. When a subsequent heating section does not need to adopt a higher temperature, the electric heating plate lowers the temperature accordingly. Less energy consumption can be used to ensure that the raw materials are in the best state. By adding a heat preservation plate at the front end of the barrel, it is ensured that after the raw materials lose the heating source, the raw materials can also maintain the best temperature during the conveying process, thereby improving the product quality.
