Molding structure and heating method thereof

A molding structure comprising a first mold body, a second mold body suited for combining with the first mold body, a molding core, a first heating element, and a second heating element is provided. Amold cavity is formed between the first mold body and the second mold body when the first mold body and the second mold body are joined together. The molding core is disposed in the mold cavity, wherein the molding core comprises a body, an inner surface, and an outer surface. The first heating member is disposed through the body to heat the molding core. The second heating element is movably disposed on the outer surface of the molding core to preheat the molding core. 种模具结构，包括第模体、适于与第模体结合的第二模体、模仁、第加热件以及第二加热件。当第模体与第二模体结合之后，模穴形成于第模体与第二模体之间。模仁则是配置于模穴，其中该模仁具有本体、内表面以及外表面。第加热件穿设于本体，以对模仁加热。第二加热件则活动地配置于模仁的外表面，以对模仁进行预热。
