Description

Technical Field

[0001] This utility model belongs to the field of aviation tire technology, and specifically relates to an aviation tire rubber extrusion device. Background Technology

[0002] Aviation tires are core components of civil aircraft take-off and landing systems. They must withstand complex working conditions such as extreme temperatures and high-pressure impacts, and possess high strength and wear resistance.

[0003] Aviation tire rubber sheets need to have extremely high temperature resistance, impact resistance and dimensional accuracy. Traditional extrusion devices often use bolts to fix the mixing shell and the discharge part. When changing the die, multiple bolts need to be removed, which is inefficient. Utility Model Content

[0004] The purpose of this invention is to provide an aircraft tire rubber extrusion device, which aims to solve the problems mentioned in the prior art.
