Description

1
Изобретение относитс  к способу изготовлени  многослойных полых изделий из полимерных материалов методом инжекционного формоВани  с последующим выдуванием.
Известен способ изготовлени  многослойных полых изделий, включающий операции инжекциопного формовани  заготовки и окончательного изготовлени  полого издели  выдуванием.
Известный способ не обеспечивает получени  многослойных изделий высокого качества .
Предложенный способ изготовлени  многослойных полых изделий отличаетс  от известного тем, что дутьевой стержень с размещенной на нем предварительно изготовленной заготовкой внутреннего сло  устанавливают в матрицу, в которой инжекционным формованием изготавливают заготовку наружнего сло , после чего дутьевой стержень с многослойной заготовкой помещают в матрицу дл  окончательного формовани  раздувом. Предложенный способ позвол ет повысить качество многослойных изделий.
Предложенный способ изготовлени  многослойных полых изделий иллюстрирован схемой , показанной на чертеже.
Предварительно изготовленную заготовку внутреннего сло  1, соответствующую по форме дутьевому стержню, размещают на дутьевом стержне 2, который вместе с заготовкой устанавливают в матрицу 3. В матрицу 3 посредством узла формовки 4 впрыскиванием подают полимерный материал, нагретый до в зко-текучего состо ни , дл  получени  заготовки наружного сло  5.
В процессе наполнени  полости матрицы 3, образованной внутренней поверхностью матрицы и дутьевым сте.ржнем с заготовкой внутреннего сло , воздух, наход щийс  в этой полости вытесн етс  к горловинной части матрицы и удал етс  в атмосферу через отверсти  6.
Изготовленную инжекционным формованием многослойную заготовку, расположенную на дутьевом стержне, охлаждают до температуры , при которой может быть осуществлена операци  выдувани . После чего дутьевой стержень с многослойной заготовкой помещают в матрицу дл  окончательного формовани  издели  раздувом. В процессе выдувани  внутренний слой 1 удерживаетс  прочно прижатым к наружному слою 5 под действием давлени  воздуха, подаваемого через радиальные отверсти  дутьевого стержн  2.
