Feeding and mixing equipment of injection molding machine

The utility model aims to provide feeding and mixing equipment of an injection molding machine, and relates to the field of mixing of injection molding machines. According to the feeding and mixing equipment of the injection molding machine provided by the utility model, different types of materials respectively fall into the mixing barrel from the feeding holes. After the mixing barrel receives the materials, the weighing sensor can weigh the weight of the materials so as to feed back and stop feeding the materials. After the materials are mixed, the driving piece drives the bottom door of the charging barrel to be opened, and then the mixed materials can be discharged. Therefore, in practical application, different types of materials independently fall into the material mixing barrel, the weight of the materials is obtained through the weighing sensor, after all types of materials are weighed, the material barrel bottom door is opened to discharge the materials, and the materials are mixed in the dischargin
