A fully automatic mold opening method and mold structure for a conical rubber spring vulcanization mold. The rubber injection insert of the vulcanization mold is fixed on the middle mold of the mold and moves up and down together with the middle mold to complete the connection between the mold rubber injection cylinder and the vulcanized product. The automatic separation between the molds realizes the automatic operation of the injection inserts; the guide mechanism is set between the middle mold, the valve mold and the lower mold of the vulcanization mold so that the valve mold moves up and down with the middle mold to complete the gap between the two valve molds. The separation and closing of the vulcanization mold can realize the automatic separation between the valve mold and the vulcanized product; the vulcanized product is automatically ejected by setting an ejection mechanism on the lower mold of the vulcanization mold; the bottom mold of the vulcanization mold and the lower plate of the curing equipment The fast positioning between the vulcanization mold and the vulcanization equipment is realized by setting a positioning mechanism between them. The invention realizes the automatic separation between the mold parts and between the mold parts and the vulcanized product, and avoids the highly difficult semi-automatic operation and structure of using the mobile crane back and forth.
