Description

Technical Field

[0001] The present application relates to the technical field of tire molds, and more specifically, to a device for repairing damaged parts of the outer circle of a tire mold. Background Art

[0002] With the rapid development of my country's automobile industry in recent years, higher requirements have been put forward for the quality and efficiency of tire production, and the requirements for supporting molds have also been increased accordingly. Tire molds are indispensable tools in the tire vulcanization process, affecting the appearance and performance of the finished tires. Tire molds need to be frequently installed and disassembled during use, which can easily damage the side panels of the molds, reduce the service life of the molds, affect the quality and performance of the tires, and further affect production efficiency. Therefore, when damage is found on the side panels of tire molds, the damaged parts need to be repaired in time.

[0003] At present, the main methods for repairing tire molds include manual welding, repairing and grinding, and lathe processing. Manual welding, repairing and grinding takes less time and is flexible to operate, but has high operating requirements for the staff and low repair accuracy. Low-precision molds can easily lead to appearance quality problems such as rubber edges and misaligned patterns on finished tires. Lathe processing has high repair accuracy and saves labor, but it takes a long time, is cumbersome to operate, and is inconvenient to adjust. It is impossible to raise or lower the mold according to the actual condition of the damaged part.

[0004] To solve the existing problems, a Chinese patent with publication number CN212527210U discloses a tire mold corrosion part repair device, including a shell, an electric push rod is fixedly connected to the right side of the back side of the shell, a push plate is fixedly connected to the left side of the electric push rod, the top of the push plate is fixedly connected to a push column through a connecting rod, the front of the push column is fixedly connected to a column, the bottom of the column is located on the left side of the top of the shell, and a driving device is provided in the inner cavity of the column, and the driving device includes a motor.

[0005] The above technical solution solves the problem of inconvenient adjustment of the existing tire mold repair device, does not affect the repair effect of the corroded part, improves the repair accuracy, meets the needs of users, and is practical. However, there are still the following shortcomings: during repair, the mold is fixed on the mounting seat, and the position of the grinding wheel is adjusted only by the column and the movable plate, and only point-to-point repair is possible. When continuous damaged parts appear on the mold, the position of the column and the movable plate needs to be adjusted continuously, which is cumbersome to operate, time-consuming to repair, and low in efficiency.
