AI Technical Summary
Existing feeding devices for injection molding of automotive parts suffer from low feeding efficiency, poor adaptability, and difficulty in cleaning, making it difficult to meet the needs of large-scale, high-efficiency production. Furthermore, manual operation can easily lead to uneven feeding, affecting the molding accuracy and consistency of injection molded products.
An automatic feeding device including multiple hoppers and a material changing mechanism was designed. By setting up a conical hopper, a mixing and crushing component, a feeding mechanism and a heating component, it can realize the automatic switching and feeding of plastic raw materials of different types, colors or particle sizes. Combined with a three-axis moving mechanism and a workpiece clamp, it can realize automated material picking and reduce manual intervention.
It improves the flexibility and adaptability of feeding, ensures the uniformity and stability of feeding amount, enhances the molding accuracy and production efficiency of injection molded products, reduces the intensity and cost of manual labor, and improves the degree of automation in production.
