Abstract: A waterproof gasket structure and its gasket shaping mold are provided. The gasket shaping mold includes a mold seat having a surface, and plural mold cavity ring-grooves concavely formed on the surface, each having two corresponding longitudinal groove sections. At least one longitudinal groove section has one or more inwardly bent wavy bent portions, and plural turning round corner portions are formed at the junction between the longitudinal groove section and the wavy bent portion, and each turning round corner portion has a radius equal to or greater than 6 mm. Therefore, the middle of the mold cavity ring-groove can be utilized effectively, and plural waterproof gaskets can be manufactured by the same gasket shaping mold while achieving the effects of reducing the mold volume, improving the manufacturing efficiency, and saving the manufacturing cost.
