Abstract

Przedmiotem wynalazku jest sposób wytwarzania elementów z tworzyw sztucznych o dużych powierzchniach i cienkich ściankach z wykorzystaniem formy wtryskowej z co najmniej jedną wkładką formującą, obejmujący następujące etapy: A. opuszczenie grzałek indukcyjnych na ramieniu, B. włączenie grzałek indukcyjnych i nagrzanie powierzchni wkładki formującej, C. wyłączenie grzałek indukcyjnych i podniesie ich poza obrys formy wtryskowej za pomocą ramienia, D. zamknięcie formy wtryskowej, E. wtrysk gorącego uplastycznionego tworzywa sztucznego pod ciśnieniem, F. chłodzenie formy wtryskowej, G. otwarcie formy wtryskowej i wypchnięcie wypraski, H. schowanie elementów wypychających wypraskę, charakteryzujący się tym, że stosuje się wkładkę formującą (2), która posiada w swojej strukturze komory (5) wypełnione materiałem o gęstości mniejszej lub o gęstości większej niż gęstość materiału, z którego wykonana jest pozostała część wkładki (2).The subject of the invention is a method of producing plastic elements with large surfaces and thin walls using an injection mold with at least one forming insert, comprising the following stages: A. lowering the induction heaters on the arm, B. switching on the induction heaters and heating the surface of the forming insert, C switching off induction heaters and lifting them beyond the outline of the injection mold with the help of an arm, D. closing the injection mold, E. injection of hot plasticized plastic under pressure, F. cooling the injection mold, G. opening the injection mold and pushing the mold out, H. storing the elements pushing out the compact, characterized in that a molding insert (2) is used, which has in its structure chambers (5) filled with material with a density less or more than the density of the material from which the remaining part of the insert (2) is made.
