Description
Способ формовани изделий из пластмасс с глубокими отверсти ми по авт. св. № 106661 известен.The method of forming plastic products with deep holes in the ed. St. No. 106661 is known.
В предлагаемом усовершенствовании, с целью получени изделий с криволинейной поверхностью и сквозными отверсти ми, массу формуют в пресс-форме с неразъемной матрицей и в расплавленном состо нии продавливают насквозь стальными штыр ми.In the proposed improvement, in order to obtain products with a curved surface and through holes, the mass is molded in a mold with a one-piece die and in a molten state is forced through through steel pins.
Использование этого способа дает возможность расширить ассортимент изделий с наружной поверхностью произвольной кривизны и сквозными гладкими отверсти ми, снизить стоимость пресс-форм дл этих изделий; увеличить производительность пресс-форм, снизить расход прессматериала за счет уменьшени грата и отходов, снизить себестоимость изделий.Using this method makes it possible to expand the range of products with an outer surface of arbitrary curvature and through smooth openings, to reduce the cost of molds for these products; to increase the productivity of molds, to reduce the consumption of press material due to the reduction of scrap and waste, to reduce the cost of products.
На чертеже изображена пресс-форма дл корпуса катушки, в разрезе .The drawing shows a mold for the coil body, in section.
Изделие по предлагаемому способу оформл етс пуансоном / и матрицей 2. Прессматериал загружаетс в матрицу, при этом стержни 3, Оформл ющие отверсти , наход тс вне матрицы. После смыкани пуансона с матрицей материал в расплавленном состо нии заполн ет полости, оформл ющие издели . Затем стержки 8 впрессовываютс в разм гченную пластмассу при помощи бокового гидроцилиндра 4, размешенного на траверсе 5, укрепленной на колоннах 6 пресса. Плунжер 7 гидравлического цилиндра ввертываетс во втулку 8.The product according to the inventive method is formed by a punch / and die 2. The press material is loaded into the die, while the rods 3, the exit holes, are outside the die. After closing the punch with the matrix, the material in the molten state fills the cavities that decorate the product. The rods 8 are then pressed into the softened plastic with the help of a lateral hydraulic cylinder 4 placed on a cross-member 5 fixed on the columns of the press 6. The plunger 7 of the hydraulic cylinder is screwed into the sleeve 8.
С целью получени сквозного отверсти , пресс-форма имеет спедующую особенность: к пуансону привернзта пластина 9 винтом 10 (после привертывани головка винта зашлифовываетс ), в матрице расположена пластина 11. В стыке этих пластин просверливаютс отверсти 12, предназначенные дл избытка пластмассы и дл входа свободных концов стержней, оформл юшие сквозные отверсти изделий.In order to obtain a through hole, the mold has a slowing feature: plate 9 is screwed to the punch with screw 10 (the screw head is ground after screwing in), plate 11 is located in the matrix. the ends of the rods, formed through the holes of the products.
