Description

Technical Field

[0001] This utility model relates to the field of vulcanized rubber molds, and more specifically, it is a positioning and error prevention device for vulcanized molds. Background Technology

[0002] As is well known, during the production of bias-ply engineering tires, the tire blank needs to be placed in the lower mold, and the upper mold is placed on the lower mold by a gantry crane to match the lower mold. However, during the matching process, because the pattern position of the mold is fixed, if it is not fully aligned or the mold is rotated 180°, the mold is aligned but the pattern is misaligned, resulting in the production of defective products. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides a vulcanizing mold positioning and anti-misalignment device to prevent the upper mold from being misplaced, ensuring that the upper and lower molds are horizontally aligned.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a vulcanizing mold positioning and error prevention device, including an upper mold and a lower mold, characterized in that, a #1 positioning block, a #2 positioning block, a #3 positioning block and a stop block are fixed at symmetrical positions on the upper side edge of the lower mold, and a #1 positioning groove, a #2 positioning groove, a #3 positioning groove and a stop block groove are machined at symmetrical positions on the lower side edge of the upper mold. The #1 positioning block, the #2 positioning block and the #3 positioning block are frustoconical structures, and the cavities of the #1 positioning groove, the #2 positioning groove and the #3 positioning groove match the frustoconical structure of the #1 positioning block, the #2 positioning block and the #3 positioning block. The stop block is a square column structure, and its upper end face is higher than the upper surface of the lower mold. The stop block groove matches the stop block.

[0005] The beneficial effects of this utility model are that it can ensure the matching and uniqueness of vulcanizing molds, eliminate the generation of defective products, and save manufacturing costs. Attached Figure Description

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] In the figure, the present invention includes an upper mold 1 and a lower mold 2. The lower mold 2 has a 1# positioning block L1, a 2# positioning block L2, a 3# positioning block L3 and a stop block C fixed at symmetrical positions on the upper side edge. The upper mold 1 has a 1# positioning groove M1, a 2# positioning groove M2, a 3# positioning groove M3 and a stop block groove D machined at symmetrical positions on the lower side edge. The 1# positioning block L1, 2# positioning block L2, and 3# positioning block L3 have a frustum-shaped structure. The cavities of the 1# positioning groove M1, 2# positioning groove M2, and 3# positioning groove M3 match the frustum-shaped structures of the 1# positioning block L1, 2# positioning block L2, and 3# positioning block L3. The stop block C has a square column structure, and its upper end face is higher than the upper surface of the lower mold 2. The stop block groove D matches the stop block C. The stop block C cannot be inserted into the 1# positioning groove M1, 2# positioning groove M2, and 3# positioning groove M3.

[0015] When the upper mold 1 is rotated 180°, the stop block C prevents misalignment, and the upper mold 1 and lower mold 2 cannot be horizontally aligned, preventing the molds from closing properly. Only when the stop block groove D is aligned with the stop block C can the operator place the tire blank into the lower mold 2 of the vulcanizing mold, use a hoisting tool to lift the upper mold 1 of the vulcanizing mold, align the #1 positioning groove M1, #2 positioning groove M2, and #3 positioning groove M3 with the #1 positioning block L1, #2 positioning block L2, and #3 positioning block L3, match and close the upper mold 1 and lower mold 2, and then place the matched vulcanizing mold into the vulcanizing tank for vulcanization.
