As　a　key　process　in　the　rubber　sealing　molding,　vulcanization　has　a　significant　impact　on　the　performance　of　rubber　sealing　products.　However,　the　rubber　industry　often　adopts　empirical　vulcanization　molding　methods,　lacking　understanding　of　the　evolution　of　vulcanization,　making　it　difficult　to　theoretically　guide　the　actual　production　process　of　rubber　seals.　In　response　to　this　weak　link　that　restricts　the　improvement　of　rubber　sealing　quality,　the　paper　conducted　numerical　simulation　research　on　the　vulcanization　molding　process　of　rubber　seals.　A　transient　simulation　model　for　thermal-chemical　coupling　of　rubber　products　was　established　based　on　an　integral　reaction　kinetics　model　and　a　heat　transfer　control　equation　with　variable　physical　parameters.　Real　time　prediction　of　the　time-varying　temperature　field　and　vulcanization　degree　field　during　the　rubber　product　forming　process　was　achieved,　and　the　correctness　of　the　model　and　solution　method　was　verified　through　experiments.　Furthermore,　the　vulcanization　process　of　typical　structural　seals　was　simulated　and　analyzed,　and　the　influence　of　mold　temperature,　rubber　preheating　temperature　and　temperature　fluctuation　behavior　on　the　rubber　seal　vulcanization　molding　process　was　discussed.　Finally,　suggestions　and　references　were　provided　for　the　actual　vulcanization　production　of　rubber　seals.　©　2024　Materials　China.　All　rights　reserved.
