[0002] The utility model, with publication number CN221339679U, discloses a mold for forming a wear-resistant solid tire, comprising an upper platform, an upper mold body, a lower mold body, and an inner mold body. The inner mold body is mounted on the lower side of the upper platform via a lifting mechanism, and the upper mold body is movably mounted on the lower side of the inner mold body via a connecting rod. The lower side of the upper mold body is provided with an upper groove, and the center of the upper groove is provided with a slot hole that penetrates the upper mold body. The lower mold body is arranged below the upper mold body, and the upper side of the lower mold body is provided with a lower groove. The inner mold body can be inserted into the slot hole, so that the lower groove, the upper groove, and the outer wall of the inner mold body form a tire-shaped cavity. A limit rod is vertically provided on the lower side of the upper platform, and a through hole that cooperates with the limit rod is provided on the inner mold body. The lifting mechanism drives the inner mold body and the upper mold body to rise, first separating them from the lower mold body, and then, under the action of the limit rod, the inner mold body is pulled out of the upper mold body, so that the formed tire automatically falls off, eliminating the need for manual separation of the inner mold body, reducing labor intensity and improving production efficiency.
