| During on the tire vulcanization mold, mold closing, the Arched seat, are fixedtogether with screw and block, complete radial motion through mutual contact with theslide plate and the guide bar. In the process of temperature heat transfer, the heat the heattransfer released transfers to the inner tire mold cavity through the arched seat. So thechange of the arched seat structure, accompanied by the tire mold cavity temperaturechanged, not only changed the machining process, but also changed the heat transferprocess, influenced the quality of the vulcanized tire. Tire vulcanization quality changeswith the mold temperature field of tire change, by through the uniformity of innertemperature of tire mold cavity.This paper by changing the structure of the arched seat, in effect to the tire reducemold temperature field, first applies the3D design software modeling assembly tire mold,uses finite element analysis software(ADINA), simulates9.00R20、10.00R20、11.00R20、and10.00R20of1188shell of the inclined plane tire segmented mould on the heattransfer process of temperature field in the mould during the curing process, analyzes theresults of simulation analysis, put forward the improvement scheme of the arched seataccording to the temperature transfer. And conducts tire mould’s heat transfer simulationafter the change of the arched seat structure, designs to structure of the smaller cavitytemperature changes, examines the uniform distribution of cavity temperature. And then through the simulation of heating up the moulds, looks over program effectiveness ofarched seat structure, analyzes the temperature distribution of tire to verify the feasibilityof the program. Then combined with simulation of the conical plane tire segmentedmould, looks over the cavity temperature distribution before and after the arched seatthrough simulation, compares with the influence of the cavity temperature field in twokinds of tire radial parting mould mold for the guidance to the actual production of theenterprise. |
