Description

СПОСОБ ИЗГОТОВЛЕНИЯ ИЗДЕЛИЙ ИЗ СТЕКЛОПЛАСТИКОВMETHOD OF MANUFACTURING PRODUCTS FROM GLASS-PLASTICS

Известны способы изготовлени  изделий из стеклопластиков, включающие операции помещени  материала в пресформу, прессовани  и извлечени  издели .Methods are known for the manufacture of articles of fiberglass, including the steps of placing the material in the mold, pressing and removing the product.

Извлечение издели  из прессформ требует дополнительното времени и специальных приспособлений , что значительно усложн ет способ изготовлени  изделий.Removing the product from the molds requires additional time and special tools, which greatly complicates the method of manufacturing products.

Извлечение изделий с помощью сжатого(воздуха не пригодно дл  съема изделий из полиэфирного стеклопластика, так как последний имеет незначительную усадку при охлаждении .Extraction of products using compressed (air is not suitable for removal of products from polyester fiberglass, as the latter has a slight shrinkage during cooling.

Дл  упрощени  способа предлагаетс  на несовпадающие участки матри цы и пуансона наносить слой воска, а затем всю поверхность пуансона и 1матрицы покрывать слоем поливинилового спирта.In order to simplify the process, it is proposed to apply a layer of wax on the non-coinciding areas of the matrix and the punch, and then cover the entire surface of the punch and the matrix with a layer of polyvinyl alcohol.

На фиг. 1 пОКазано нанесение слоев воска и поливинилового спирта на пуансон и .матрицу; на фиг. 2 - извлечение издели  s начальный момент раскрыти  прессформы; на фиг. 3 - положение издели  в момент полного раскрыти  прессформы.FIG. 1 POKAZANO applying a layer of wax and polyvinyl alcohol on the punch and the matrix; in fig. 2 - removing the product s the initial moment of opening the mold; in fig. 3 - the position of the product at the time of full disclosure of the mold.

На предварительно подготовленную поверхность нанос т разделительный слой, представл ющий собой комбинацию пленок на основеA release layer is applied to the pre-prepared surface, which is a combination of films based on

растворов воска и поливинилового спирта. При этом одним слоем / и 2 раствора воска покрывают матрицу 5 от а до О, а пуансон 4-соответственно от б до О. Затем всю рабочую поверхность прессформы, подогретую до температуры 25-35°С, покрывают двум  сло ми 5 и 6 раствора поливинилового спИ|рта. После этого в матрицу 3 укладывают стеклонаполнптель и подают св зующее, затем опускают пуансон 4, и при температуре 60-70° св зующее полимеризуетс .solutions of wax and polyvinyl alcohol. At the same time, one layer / and 2 wax solutions cover the matrix 5 from a to O, and the punch 4, respectively, from B to O. Then the entire working surface of the mold, heated to a temperature of 25-35 ° C, is covered with two layers 5 and 6 of the solution polyvinyl spi | mouth. After that, the glass-filler is laid into the matrix 3 and the binder is fed, then the plunger 4 is lowered, and at 60-70 ° C, the binder is polymerized.

В процессе полимеризации слой 1 w. 2 воска подплавл етс , и в местах его нанесени  резко уменьшаетс  адгези  издели  к оснастке. ВIn the process of polymerization layer 1 w. The wax 2 is melted down and at the places of its application the adhesion of the product to the tooling is sharply reduced. AT

результате этого в момент размыкани  прессформы возникает пара сил (Pj и Ро), котора  отрывает изделие от матрицы и пуансона.As a result, at the moment of uncoupling the mold, a pair of forces (Pj and Ro) occurs, which separates the product from the die and the punch.

Предмет изобретени Subject invention

Способ изготовлени  изделий из стеклопластиков , включающий операции помещени  материала в прессформу, прессовани  и извлечени  издели , отличающийс  тем, что, с целью упрощени  способа, на несовпадающие участки матрицы и пуансона нанос т слой воска, а затем всю поверхность пуансона и матрицы покрывают слоем поливинилового спиртаA method of manufacturing products from fiberglass plastics, including the steps of placing the material in a mold, pressing and removing the product, characterized in that, in order to simplify the method, a layer of wax is applied to the uneven areas of the matrix and the punch, and then the entire surface of the punch and the matrix is covered with a layer of polyvinyl alcohol
