Description

Technical Field

[0001] This utility model relates to the field of busbar mold technology, specifically to an automotive busbar mold integrating multiple ejector pins. Background Technology

[0002] In the injection molding process of automotive busbar rings, the products typically include a plastic matrix, embedded metal strips, and various functional structures such as local protrusions. The molding precision and demolding requirements differ significantly between these different structures. Existing automotive busbar ring molds generally use single-specification ejector pins for demolding, resulting in highly homogenized ejector pin structures. This makes it impossible to achieve precise adaptation for different functional areas of the busbar ring. For the metal strip mounting area, ordinary ejector pins struggle to provide effective contact and positioning, leading to easy displacement and loosening of the metal strip during injection molding. For local protrusion structures, the lack of targeted snap-fit ​​positioning design easily results in problems such as protrusion deformation and dimensional deviations after molding. Furthermore, the assembly relationship between the ejector pins and the busbar ring molding unit is poorly designed, with some molds exhibiting insufficient ejector pin positioning accuracy and uneven force during demolding. This leads to low overall dimensional accuracy and high cooling deformation rate in the busbar products, making it difficult to improve product yield.

[0003] Furthermore, the existing mold's ejector pin assembly lacks coordination with the molding and ejection units. Either the ejection action fails to smoothly drive the ejector pin to precisely disengage from the manifold ring, or the ejector pin structure lacks sufficient strength, leading to breakage and deformation over long-term use. This not only affects production efficiency but also increases mold maintenance costs. When producing multi-specification manifold rings, existing molds struggle to quickly adapt to the molding requirements of different manifold ring structures, necessitating the replacement of the entire mold or numerous parts. This results in poor production flexibility, high equipment investment costs, and an inability to meet the demands of large-scale, multi-variety production. Therefore, there is an urgent need for an automotive manifold ring mold that integrates multiple ejector pins, can precisely adapt to different functional areas of the manifold ring, and offers structural stability and smooth demolding, to address the shortcomings of existing technologies.
