The first core mold and the second core mold are provided with core mold pushing slopes on the outer sides of the upper ends, and upper mold pushing slopes are provided at both ends of the core mold groove of the upper mold. The upper mold pushing slopes and the core mold pushing slopes interact with each other during the closing process of the upper mold and the lower mold, pushing the two mold cores to move toward the direction of the cavity to achieve closing.

[0005] Furthermore, the first core mold and the second core mold are provided with core mold arc surfaces on the outer sides of the lower ends, and lower mold arc surfaces are provided at both ends of the core mold groove of the lower mold. The core mold arc surface and the lower mold arc surface on the same side are concentric arcs.

[0006] Furthermore, waist-shaped holes are provided in the first core mold and the second core mold.

[0007] Furthermore, a rotating shaft is arranged in the waist-shaped hole, and the waist-shaped hole and the rotating shaft cooperate to realize the functions of rotation and left-right movement.

[0008] Furthermore, the inner hole of the waist-shaped hole is concentric with the arc surface of the core mold on the same side thereof, thereby ensuring that horizontal movement can be achieved while rotating.

[0009] Furthermore, the rotating shaft is located at the center of the arc surface of the core mold on the same side.

[0010] Furthermore, the rotating shaft is fixedly connected to the lower mold by bolts.

[0011] Furthermore, a positioning bevel is provided on the upper mold, and the positioning bevel is used to limit the moving position of the core mold.

[0012] Furthermore, the upper mold, core mold, rotating shaft and lower mold are divided into left and right molds.

[0013] The beneficial effects of the utility model are as follows: the utility model provides a butt-joint vulcanization mold structure, which effectively reduces the width of the interface and improves the appearance quality of the interface. It not only ensures the appearance quality of the interface, but also ensures the strength of the interface. The mold of this structure is divided into an upper mold, a core mold, a lower mold and a rotating shaft. Each part realizes the upper and lower mold closing and the left and right mold closing of the core mold through the coordination of equipment, which can adapt to the sealing butt-joint vulcanization of complex structures.
