Description
Изобретение относитс к переработ ке термореактивных полимеров и может быть использовано дл изготовлени изделий литьем под давлением.The invention relates to the processing of thermosetting polymers and can be used for the manufacture of injection molded articles.
Цель изобретени - сокращение, продолжительности формовани изделий повышение их качества за счет исключени короблени и обеспечение возможности изготовлени с различной массой в одной форме.The purpose of the invention is to reduce the duration of the molding of products to improve their quality by eliminating warping and ensuring the possibility of manufacturing with different weights in one form.
На фиг. 1 - 3 изображены схемы устройств дл осуществлени способа с нагревом различных участков литниковой системы.FIG. 1 to 3 are schematic diagrams of devices for carrying out the method with heating different parts of the gating system.
Способ осуществл ют следующим образом .The method is carried out as follows.
Полимерный термореактивный матери , ал загружают в бункер литьевой машины и осуществл ют его пластикацию в цилиндре 1 литьевой машины.Polymer thermosetting mother, al is loaded into the hopper of the injection molding machine and it is kneaded in the cylinder 1 of the injection molding machine.
Затем подвод т цилиндр 1 к форме и осуществл ют впрыск материалаCylinder 1 is then applied to the mold and material is injected.
через обогреваемую литниковую систему в обогреваемые оформл ющие полости формы 2, причем вьше температуры оформл ющих полостей формы на 1080 С нагревают всю литниковую систему 3 - 5 (фиг, 2), или центральный участок 3 (фиг. 1) , развод щие участки 4 (фиг. 3), включа впускные литники 5.through the heated gating system into the heated shaping cavities of the mold 2, with the entire temperature of the shaping cavities of the mold at 1080 ° C heating the entire gating system 3 - 5 (Fig 2), or the central portion 3 (Fig. 1), the diluting portions 4 ( Fig. 3), including inlet sprues 5.
Материал за врем прохождени через литниковую систему разогреваетс до температуры оформл ющих по- постей формы.The material during the passage through the gating system is heated to the temperature of the shaping posts.
Далее производ т отверждение материала , форму размыкают, изделие извлекают и цикл повтор ют вновь.Next, the material is cured, the form is opened, the product is removed and the cycle is repeated.
Результаты осуществлени предла- гаемого способа при различных параметрах процесса представлены в таблице.The results of the implementation of the proposed method with various process parameters are presented in the table.
