The Optimization Of Structure And Heat Transfer-Stress Simulation On Segmented Mould Based On Ansys Workbench

The tire segmented mould is a necessary place for tire vulcanization. Tire vulcanization quality efficiency depends on the uniformity of the temperature field inside the mold, by through the uniformity of inner temperature of tire mold cavity. Therefore, it’s quite necessary to control the stability of the mold cavity temperature distribution for the improving of tire production quality and efficiency of tire production. According to the segmented mould cavity’s temperature field distribution reports, the segmented mould cavity’s temperature field distribution isn’t uniformity nowadays. This article mainly researched on the numerical simulation of mould temperature field in the process of heating up the mould. By the finite element simulation software ANSYS Workbench as the tool in this article, mainly researched on the numerical simulation of mould temperature field in the process of heating up the mould. Analyze the simulation results and summarize the heat transfer rules. Mainly from three aspects to consider that decrease cavity temperature difference, short die preheating time and three reducing mold quality by temperature transfer rules. Propose improvement of mold structure and correspond simulation analysis on the heat transfer and stress analysis, then designed the best mould structure in order to control temperature field properly and improved the tire production quality and efficiency. This article mainly researched on the following aspects:(1) Firstly this paper introduced the theoretical analysis of temperature field problem in segmented mould, including temperature control method, the method of solving temperature field and the calculation model of the segmented mould.(2) The original model of the segmented mould is to heat-stress simulation analysis, then according to the result of simulation date to research the law of heat transfer. Finally put forward the improvement scheme and observe the change of heat transfer process, then check the strength of the new structure, and draw the corresponding conclusion.(3) Bow-shape seat as an important part of segmented mould and Temperature transfer no longer be in the form of symmetry because of his special structure, which led to the tire vulcanization quality. Optimization research of new structure is done through Solid Works and ANSYS Workbench build collaborative simulation platform. The design of new structure for bow-shape seat can be optimized, optimal structure of are determined. Update the mold structure, to heat transfer simulation analysis and to observe the change of heat transfer process.(4) The tire assembly into the tire segmented mould, heat transfer model is analyzed. And will be described above the favorable solution for the same simulation analysis. Get the mold structure on the temperature distribution of the tire and the influence of the mold cavity temperature distribution is the same. Further validation protocols for the influence of tire vulcanization.
