The Design And Research Of Three-station Solid Tire Injection Molding Curing Unit

Tires can be divided into two major categories,solid tires and pneumatic tires. Tire industry has a significant role in the national economy, and it is closely related to people's lives. Thus, this country attaches great importance to the development of the tire industry in modern society. Especially in the pneumatic tire industry there was a rapid development. At present, tire production in China has exceeded 400 million each year. On the other hand, solid tire industry in China has never been properly developed, whose production is only tens of thousands eacn year. Cause problems are not only ideas but also the production technology. Solid tires have a wide range of applications in the USA and European countries. As long as the speed is not more than 80km / h they are commonly used in vehicle tires. Solid tires do not require inflation, and do not worry for puncture. And they have high pressure capability, for they have a relatively small diameter. They also have long life and maintenance more convenient.Now, the solid tire is still using the traditional molding, winding method and centrifugal casting method. These methods use more equipment, complex process, energy consumption, and low tire finished products, poor quality tires etc. They can not meet the demand for quantity and quality of solid tires. For the development of solid tire injection molding, we conducted a design study for three-station one-step injection of solid tire technology and equipment.In this issue, we have done related work and got the following results:1. Design the three-station one-step injection of solid tires equipment at home and abroad for the first time. This equipment can inject 200,000 g's main battle tank load solid tire one time .2. Design solid tires electric ejection device for the first time in China. The devices use a modern industrial high-precision ball screw principle of non-self-locking, combining of the characteristics of electromagnetic clutch. Successfully designed electric ejection equipment. Though the experiments on devices by the design, it fully achieved the expected result of the design.3. Improve the one-step injection machine mold pressure sensor body mobile devices. This institution changed original rigid transmission line to a flexible transmission line. It solved the phenomenon of the lag between pressure sensor signal and display instrument. And guaranteed the stability of pressure control .And then ensured the reliability of machine work.4. Design a one-step injection solid tires mold at home for the first time, in the absence of reference material conditions. It considered the issue of mold exhaust, flow injection system problems and stripping problems. It established the foundation of the one-step injection solid tires.5. Design the overall structure of the three-station injection molding and curing. The whole equipment has high productivity, reasonable force, small deformation and reliable working. It can be automated and continuous production.6. Design the flow channel plate for the mold which use BET method. The rubber injection port due to flow down to avoid leakage generated by uneven forces the flow suffered.7. Using finite element analysis software in design. We carried out finite element analysis for important components. The structure of the analysis of different options had been analyzed. The deformation calculated with finite element method were compared. And then made evaluation of various options for optimization. Make the structure more reasonable and reliable.8. Make parameterized three-dimensional shape design and dynamic process simulation. Using motion simulation of the machinec, we discovered and solved the existence of irrational design and finterference phenomena. To achieve the optimal design and improve the design level.
