Description

[0001] The invention relates to the field of injection molding technical equipment, in particular to a hybrid insulator injection molding machine. Background Art

[0002] Insulators are important electrical equipment, widely used in power systems to support and insulate key components such as wires and conductors. With the rapid development of power systems and the continuous improvement of insulator performance requirements, traditional insulator production processes have been unable to meet the needs of modern production. Especially in the injection molding process, the single processing station, complex operation process and low production efficiency have become bottlenecks restricting the development of the insulator manufacturing industry.

[0003] Existing insulator injection molding machines usually adopt a single-station design, and the injection, mold closing, and mold opening processes require frequent manual intervention, resulting in low production efficiency and difficulty in ensuring product quality. In addition, the control system level of these devices is not high, making it difficult to achieve precise process control and automated operation.

[0004] Therefore, developing injection molding machines with high production efficiency, high-quality products, simplified operating procedures and high intelligence levels can meet the high standards required by modern power systems for insulator production and application.
