Description
Известны формы дл прессовани изделий из термопластичного материала, например стекла, включающ-ие кольцо, иуансои н матрицу . В издели х, огирессованиых в таких формах , получение отверстий требует специальной технической обработки. Предлагаема форма позвол ет образовывать в дне издели сквозные отверсти одновремеино с приданием геометрической формы. Достигаетс это тем, что матрица формы выполнена с иодпружииенным плунжером, расиоложенным с ее нижней части. На фиг. 1 и 2 показана онисыоаема форма в разрезе по вертикали (до прессовани и в конце его). Форма включает кольцо 1, пуансон 2, матрицу 3 с подпружиненным плунжером 4. Дозированна порци стекломассы 5 подаетс в матрицу ИЗ питател так, чтобы ома заи ла место не но оси формы, а сбоку между стенкой матрицы и нлуижером, выдвинутым с помощью нружины 6 в крайнее верхнее положение . Пуансон, опуска сь в матрицу, нриходнт н соприкосновение с плунжером и вместе с ним нродолжает свой нуть, преодолева усилие нружнны 6, до крайнего нжнего положени . Упором дл пружины служит специальна гайка 7. Стекломасса, заполн все промежутки между пуансоном и матрицей, приобретает форму готового издели со сквозным отверстием диаметром, равным диаметру плунжера. Затем пуансон поднимаетс вверх но вертикали , отрыва сь на своем нути от плунжера, К изделие может быть нзвлечеио из формы. Предмет i з о б р е т е н н Форма дл прессованн изделий из термонластичного материала, например стекла, включающа кольцо, пуансон и матрицу, О7личающа с тем, что, с целью образовани в дие издели отверстий, матрица формы выполнена с подпружиненным плунжером, расположенным в ее нижней части.Forms are known for pressing articles from a thermoplastic material, for example glass, including a ring, a junction and a matrix. In products that are ogressed in such forms, the production of holes requires special technical processing. The proposed form allows to form through holes in the bottom of the product at the same time while giving a geometric shape. This is achieved by the fact that the mold matrix is made with an iodoped plunger located from its lower part. FIG. Figures 1 and 2 show the shape shown in the vertical section (before pressing and at the end). The form includes a ring 1, a punch 2, a matrix 3 with a spring-loaded plunger 4. The dosed portion of glass melt 5 is fed into the matrix FROM the feeder so that it places not only the axis of the form, but on the side between the wall of the matrix and the neutralizer pushed out by means of a spring 6 in extreme top position. Punch, lowering into the matrix, take it back into contact with the plunger, and with it, continue to rely, overcoming the force of the external force 6, to the extreme low position. The spring for the spring is a special nut 7. The glass melt, filling all the gaps between the punch and the die, takes the form of the finished product with a through hole with a diameter equal to the diameter of the plunger. Then, the punch rises upward but vertically, detaching itself from its plunger on its thread. A product may be removed from the mold. Item i d o d e n n A mold for extruded articles from thermoelastic material, for example glass, including a ring, a punch and a die, which, in order to form holes in the article, is made with a spring-loaded plunger, located at its bottom.
