Abstract

Patente de Invenção: <B>"MáQUINA PARA MOLDAGEM POR INJEçãO, ASSIM COMO PROCESSO PARA A FABRICAçãO DE PEçAS MOLDADAS POR INJEçãO EM FORMA DE BUCHA, ESPECIALMENTE PRé-FORMAS"<D>. Propõe-se, quando da fabricação de corpos pré-formados para garrafas PET, as chamadas pré-formas, melhorar a região de refrigeração e de refrigeração subseq³ente, respectivamente. Parte-se primeiramente de uma refrigeração à água também na refrigeração subseq³ente. No entanto, a atuação do ar é melhorada, contanto que elementos mecanicamente deslocáveis são alocados à atuação do ar. Deste modo pode ser melhorada a segurança com respeito a falhas quando da manipulação ("Handling"), no entanto da mesma foram também o efeito de refrigeração. Em primeiro plano figuram dois aperfeiçoamentos especialmente vantajosos, os quais em combinação resultam em uma solução ótima. Para a ejeção propõe-se um elemento semelhante a uma válvula, e para o interior das pré-formas um bocal de ar, o qual apóia a manipulação ("Handling") como também a refrigeração.
