AI Technical Summary
⚠Technical Problem
During the material feeding process in a high-speed injection molding machine, the hot air generated by the heat pipe comes into direct contact with the material, causing it to become damp and sticky, which affects the injection rate.
⚗Method used
The hopper is heated by a ring-shaped heat-conducting plate and a water pump system. Airflow is introduced through an air pump and nozzles to preheat the material. Combined with a fan to remove moisture, heat loss is reduced and material sticking is prevented.
🎯Benefits of technology
Effective preheating of materials prevents them from sticking, increases injection speed, reduces heat loss, and ensures efficient operation of the injection molding machine.

Abstract
This utility model discloses an injection structure for a high-speed injection molding machine, including a hopper, an injection tube, a spiral feed rod, and a heater. An annular heat-conducting plate is uniformly and fixedly connected to one side of the injection tube near the heater. An annular sleeve is provided outside the annular heat-conducting plate and is fixedly connected to one side of the injection tube. A guide pipe is fixedly connected to one side of the annular sleeve and is fixedly connected to the hopper. A spiral guide pipe is fixedly connected inside the hopper and communicates with the guide pipe. A water pump is fixedly connected to one side of the hopper, and a return pipe is fixedly connected to one end of the water pump. The annular sleeve is fixedly connected to one end of the return pipe. Heat-conducting rings are uniformly and fixedly connected inside the hopper. This utility model uses an annular heat-conducting plate inside the annular sleeve to absorb heat from the injection tube with water. The water pump then allows water to enter the spiral guide pipe, heating the hopper. The heat is then absorbed by the heat-conducting rings, resulting in heat inside the hopper and preheating the material, preventing material sticking and reducing the impact on injection.
