Изобретение относитс  к пререработке в издели  полимерных материалов.This invention relates to the conversion of polymeric materials into articles.

Известные пресс-формы дл  безоблойного формовани  изделий из полимерных материалов , имеющие режущие кромки на матрице и пуансоне, не обеснечивают качественного и надежного отделени  обло  из-за недорезани  и обрывов.Known molds for laminationless molding of polymeric materials, having cutting edges on the die and punch, do not ensure high-quality and reliable separation due to under-cutting and breaks.

Дл  улучшени  обрезки обло  предлагаетс  режущие кромки выполн ть заход щи.ми одна за другую при смыкании пресс-формы. Это позвол ет полностью перерезать материал обло  и тем самым повысить качество и надежность его отделени  от изделий.In order to improve the trimming, the blades suggest cutting edges to run one after the other when the mold is closed. This makes it possible to completely cut the material of the flash and thereby improve the quality and reliability of its separation from the products.

На чертеже изображена предлагаема  пресс-форма.The drawing shows the proposed mold.

Она содержит пуансон 1 с плитой 2 и матрицу 3. Пуансон имеет режущую кромку 4, облойную канавку 5 и центрирующую поверхность 6.It contains a punch 1 with a plate 2 and a matrix 3. The punch has a cutting edge 4, a lamella groove 5 and a centering surface 6.

Матрица имеет посадочную поверхность 7 и режущую кромку 8.The matrix has a seating surface 7 and a cutting edge 8.

В сомкнутой пресс-форме режуща  кромка заходит за режущую кромку 8 на глубину, по крайней мере не меньшую толщины несжимаемой пленки обло  материала.In a closed mold, the cutting edge extends beyond the cutting edge 8 to a depth of at least not less than the thickness of an incompressible film abraded material.

Пресс-форма работает следующим образом.The mold works as follows.

В гиездо матрицы 3 загружают материал и закрывают пресс-форму. Избыток материала выдавливаетс  из гнезда матрицы в канавку 5. При этом кромка 4 заходит за кромку 8.In the matrix die 3 load the material and close the mold. The excess material is squeezed out of the die cavity into the groove 5. In this case, the edge 4 extends beyond the edge 8.

При раскрыт1И1 пресс-формы кромки 4 и 8 при взаимном перемещении полностью перерезают матернал обло , освобожда  от него изделие.When the molds of the mold are opened, edges 4 and 8, when reciprocating, completely cut the material oblo, releasing the article from it.

Предмет изобретеии Subject of invention

Пресс-форма дл  безоблойного формовани  изделий из полимерных материалов , имеюща  режущие кромки на матрице и пуансоне, отличающеес  тем, что, с целью улучшени  обрезки обло , режущие кромки выполнены заход щнми одна за другую при смыкании пресс-формы.A mold for flawless molding of polymeric materials, having cutting edges on a die and a punch, characterized in that, in order to improve trimming, the cutting edges are set one after the other when the mold is closed.
