Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a double-color mold structure with a rotating mold core. Background Art

[0002] The two-color mold uses two independent injection channels and a rotating mold core design to achieve the molding of plastics of different materials or colors in the same part.

[0003] However, existing two-color molds have some drawbacks. For example, they lack a mold rotation mechanism, preventing the molded part from rotating. This prevents switching between different stages of the injection molding process, making it difficult to inject the second material. This reduces the production efficiency of two-color molds and fails to meet current market demands. To address this, we propose a two-color mold structure with a rotating mold core to address these issues. Utility Model Content
