Description

Technical Field

[0001] The utility model relates to the technical field of production of tool boxes for optical fiber fusion splicers, in particular to an injection molding die for the tool boxes for optical fiber fusion splicers. Background Art

[0002] The primary function of a fiber fusion splicer tool box is to carry the fiber fusion splicer and assist in its operation. Key design considerations include its overall shape and structure. While the surface is typically smooth, unevenness may occur due to material and lighting conditions. The tool box is designed for easy portability and use, ensuring the safety and stability of the fiber fusion splicer. Specific uses of a fiber fusion splicer tool box include: 1) Carrying the fiber fusion splicer: The tool box is designed to safely carry the fiber fusion splicer and protect it from damage. 2) Providing auxiliary tools: The tool box typically contains essential tools such as pliers, a knife, alcohol wipes, and heat shrink tubing for handling optical cables and splicing optical fibers. 3) Protecting the fiber fusion splicer: At the construction site, the tool box provides a protective case to protect the fiber fusion splicer from external interference and damage. 4) Improving work efficiency: By centrally storing all necessary tools and equipment, the tool box helps construction workers complete fiber fusion splicing tasks more efficiently.

[0003] Existing injection molding molds for fiber optic splicer tool boxes have shortcomings. First, they cannot simultaneously mold the upper and lower cases, nor can they form storage slots for the fiber optic splicer and its associated tools within their respective cavities. Second, they cannot be directly cooled from the inside after injection molding. Therefore, structural optimization and improvement are needed. Utility Model Content
