Description

Electric segmented mold driving device of tire vulcanizer

Technical Field

The utility model relates to the technical field of segmented mold operating devices of tire vulcanizing machines, in particular to an electromechanical segmented mold driving device of a tire vulcanizing machine.

Background

Vulcanizing is an important procedure in the tire production process, and the segmented mold operating device of the vulcanizing machine is an important component part of the vulcanizing machine and is used for controlling the segmented mold to open and close when the segmented mold finishes the tire loading and unloading. The traditional segmented mold operating device of the vulcanizing machine is usually driven by an air cylinder or a hydraulic cylinder, and the segmented mold operating device driven by the air cylinder or the hydraulic cylinder is required to be provided with an overflow system to complete the work. However, the hydraulic original components and pipelines installed in the overflow system are complex, and the overflow system has the defects of more easily damaged parts, high operation cost, low total efficiency, high power consumption and the like, and does not meet the requirements of energy conservation and consumption reduction.

With the development of electric control and market demands, it is proposed that electric drive can be used to replace the conventional gas-liquid drive. As disclosed in the prior patent CN217319398U, the segmented mold telescopic operating device of the tire vulcanizing machine is characterized in that an output shaft of a motor is connected with a ball screw, a clamping ring seat is matched with the ball screw, and the clamping ring seat transmits displacement to a segmented mold connecting shaft to realize driving. The segmented mold driving device needs to load the segmented mold to finish the telescopic operation, and the ball screw structure adopted by the scheme cannot bear higher load, so that the segmented mold driving device has certain limitations on service life and stability.

Meanwhile, in order to prevent the die from sliding downwards relative to the die sleeve or being pushed back by the shaping force in the self-weight state in the vulcanization shaping process, a resistance is required to be set. The traditional gas-liquid driving segmented mold operating device is realized by configuring an overflow valve to maintain pressure, and the problem that a mold slides down and is pushed back in the working process of a vulcanizing machine is considered by adopting motor driving.

Based on the problems, the segmented mold driving device driven by the motor is designed, so that the driving efficiency can be improved, the running cost can be reduced, and the loss of parts can be reduced.
