Description

Technical Field

[0001] The utility model relates to the technical field of rubber tire preparation, in particular to an electric mold adjustment and post-inflation device. Background Art

[0002] The tire post-inflation device is an important equipment used in tire vulcanization operations. It is usually used in conjunction with a tire vulcanizer. The vulcanized tire is unloaded from the vulcanizer by a manipulator and placed on the lower chuck. The tire is then fixed by the upper and lower chucks and inflated. The tire is then cooled and shaped. The existing tire post-inflation device uses the lifting and lowering movement of the crossbeam to control the lifting and lowering of the upper chuck assembly, so that the upper chuck assemblies on both sides of the column will lift and lower at the same time. When one side of the station fails, the entire post-inflation device needs to be shut down for maintenance, which causes inconvenience in maintenance and trouble in replacing parts. At the same time, the downtime is long, which seriously reduces production efficiency.

[0003] The upper and lower trays in the tire rear inflation device need to move axially. Due to the gaps in various places or the gaps caused by long-term wear, the axes of the upper and lower trays are prone to tilt, so that the two axes no longer coincide. When the tire is clamped on the upper and lower chucks, the coaxiality of the upper and lower trays is poor, the tire shaping accuracy will be affected, and the tire is prone to deformation.
