Description

Technical Field

[0001] The utility model relates to the technical field of charging terminals for new energy vehicles, in particular to a mold core-pulling mechanism for a shell of a charging terminal for a new energy vehicle. Background Art

[0002] The charging terminal of new energy vehicles is one of the important components of the charging system, and the charging terminal needs to be injection molded during processing to achieve the effect of plastic-wrapped iron. At the same time, a mold core pulling mechanism will be used when the injection molding process is completed to avoid the subsequent manual removal of all positioning pins and separation of the finished terminal from the slider. However, the existing mold core pulling mechanism of the charging terminal shell for new energy vehicles still has some shortcomings. For example, the core pulling component can generally only be translated left and right and cannot be rotated. In this way, it cannot be used effectively when encountering different angles of use. At the same time, the core pulling component and the power component cannot be disassembled, which makes it impossible to replace and adjust according to the needs of the charging terminal. For this reason, we propose a mold core pulling mechanism for the charging terminal shell of a new energy vehicle. Summary of the invention
