AI Technical Summary

Technical Problem

Existing injection molding equipment contains plastic particles with moisture and debris that are not treated, leading to product quality problems, including needle-like white streaks, bubbles and black spots on the surface. Furthermore, traditional equipment is difficult to effectively remove fine powder and impurities.

Method used

The pre-plasticized feeding device includes a mixing component, a heating air inlet component, an air outlet component, and a conveying component. The plastic particles are mixed by a mixing shaft and a mixing rod. The heating air inlet component heats the particles evenly. The air outlet component removes fine powder and impurities. The conveying component transports the pre-plasticized particles to a storage hopper.

Benefits of technology

It achieves uniform heating and effective impurity removal of plastic particles, improving the quality and production efficiency of injection molded products, and avoiding surface defects and impurity residues.

Abstract

The application relates to a pre-plasticizing feeding device for an injection molding device and belongs to the technical field of injection molding production. The pre-plasticizing feeding device comprises a pre-plasticizing barrel and a storage barrel. The pre-plasticizing barrel is internally provided with a stirring assembly, a heating air inlet assembly, an air outlet assembly and a conveying assembly. The stirring assembly comprises a stirring shaft and stirring rods. The heating air inlet assembly is provided with a heating pipe. The air outlet assembly can discharge fine powder. The conveying assembly can convey the pre-plasticized injection molding particles to the storage barrel. The discharge seat of the storage barrel is provided with a distribution pipeline and an opening and closing assembly. The pre-plasticizing feeding device can pre-plasticize the injection molding particles, effectively remove the fine powder, realize multi-pipeline distribution and precisely control the material conveying, and the like.
