Abstract

"SISTEMA DE MOLDAGEM DE TUBO PARA PRODUZIR UM TUBO DE PLáSTICO". Um molde de tubo produz um tubo de plástico com uma parede interna que possui uma primeira parte de parede e uma segunda parte de parede. O molde de tubo possui um tampão de resfriamento de dois estágios para auxiliar o endurecimento da parede de tubo. O primeiro estágio de resfriamento é controlado para remover calor da parede de tubo para endurecer parcialmente o plástico sem resfriamento excessivo. O tubo de plástico parcialmente endurecido em seguida passa por um segundo estágio onde o resfriamento do tubo ocorre com menos precisão. O tubo de plástico parcialmente endurecido é mais tolerante e está sujeito a menos danos. De preferência, tanto o primeiro como o segundo estágios incluem sensores de temperatura e mecanismos de controle separados para variar o meio de resfriamento de cada estágio. Numa realização preferida, um meio de resfriamento é circulado através de um primeiro estágio a uma temperatura e a uma taxa de fluxo que mantenham o primeiro estágio dentro de uma faixa de temperaturas estreita em torno da temperatura do meio de resfriamento. O tampão de resfriamento em estágios permite um melhor controle nas partidas iniciais e sob condições de operação variáveis.
