Description

Technical Field

[0001] The utility model relates to the field of plastic coating, in particular to a plastic coating mechanism for a composite button. Background Art

[0002] Plastic coating is a surface treatment process, which is mainly used in mechanical equipment, industrial assembly lines, furniture and hardware accessories. Specifically, plastic coating refers to wrapping a layer of plastic on the outside of metal products. This layer of plastic is usually made of nylon PA, polyoxymethylene POM and engineering plastics polypropylene, PP and other materials. The outer plastic has a certain hardness, impact resistance, friction resistance and self-lubricating property, which can provide additional protection and performance improvement. The plastic coating treatment method includes melting solid plastic into liquid plastic at high temperature, then putting in metal wire and taking it out after a period of time.

[0003] After searching, Chinese patent announcement number: CN220651726U discloses a cable plastic coating mechanism, in which molten plastic enters the material channel through the clinker pipe and then enters the plastic coating device. An annular heating plate is installed in the guide sleeve. The core wire is continuously transported to the guide sleeve and preheated by the annular heating plate in the guide sleeve. Then the core wire is transported to the plastic coating part. The core wire passing through the material channel is wrapped by the molten plastic and enters the plastic coating part, avoiding insufficient wrapping and compaction, thereby avoiding the generation of bubbles or bulging.

During the heating and melting process of the solid plastic, if there is a large volume of solid plastic, the melting time of the plastic will be increased, thereby reducing the efficiency of the overmolding. Therefore, a composite button overmolding mechanism is proposed to solve the above problem. Utility Model Content

A handle 18 is fixedly connected to the surface of the mounting frame 16. There are two groups of handles 18, and the two groups of handles 18 are symmetrically arranged with the central axis of the mounting frame 16 as the symmetry axis.
