Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to an injection molding equipment for power cord plugs. Background Technology

[0002] Electrical plugs are common and essential electrical components in daily life and production. Plugs are usually manufactured using injection molding technology. Injection molding is a process in which molten plastic material is injected into a mold cavity and then cooled and solidified to form a plastic product of the desired shape. This process is widely used in the manufacture of various plastic products, including plugs, sockets and other electronic components.

[0003] In the existing technology, plug injection molding is generally carried out in a semi-automatic production process, which requires manual operation. For example, in the wire feeding and fixing operation, the wire end needs to be placed into the injection mold by hand and the wire body needs to be tapped with a rubber hammer to make it engage and fix with the fixing groove.

[0004] Manually tapping the wire to secure it is inconvenient and can easily lead to inconsistent wire tightness, resulting in inconsistent product quality and potentially defective products. Utility Model Content

[0005] The purpose of this application is to provide an injection molding equipment for power cord plugs, which improves upon the inconvenience of manually tapping the cord to secure it, as this method is prone to inconsistencies in cord tightness, resulting in inconsistent product quality and potentially defective products.
