Изобретение касаетс .переработки пластмасс в издели .The invention relates to the processing of plastics in the product.
Известна литьева форма дл изготовлени изделий с поднутрением, содержаща обойму с наклонными штыр ми, раздвижные полуматрицы , пуаисонодержатель с пуансоном и направл ющими полуматрицами, знак, оформл ющий поднутрение, и выталкивающую систему .A well-known injection mold for the manufacture of articles with undercuts, comprising a holder with inclined pins, sliding semi-matrices, a pad holder with a punch and guide semi-matrixes, a sign that draws an undercut, and an ejector system.
Однако в такой фо;рме ограничено количество направлений, в которых могут быть выполнены поднутрени в изготовленном изделии , paiBHoe двум (направлени соответствуют направлению перем ещений полуматриц ) .However, in such a form, the number of directions in which the undercuts can be made in the manufactured product is limited to two paiBHoe (the directions correspond to the direction of semi-matrix displacements).
Прототипом изобретени вл етс литьева форма, содерл аща обойму, пуансон, раздвижные полуматрицы, размещенные в о-бойме , и формующий поднутрение знак, хвостовик которого взаимодействует с направл ющим пазом 2.The prototype of the invention is a casting mold, containing a clip, punch, sliding semi-matrix placed in an o-ball, and an undercut forming sign, the shank of which interacts with the guide groove 2.
Однако в такой фор.ме извлекаетс знак, расположенный в полуматрице.However, in such a form, a sign located in the half-matrix is extracted.
С целью извлечени знака, расположенного в плоскости разъема полуматриц, предлагаетс литьева форма, в которой направл ющие пазы выполнены в полуматрицах, а хвоСТ01ВИК знака снабжен размещенными в плоскости , перпендикул рной плоскости разъема полуматриц, колонками, расположенными подFor the purpose of extracting a mark located in the plane of the semi-matrix split, a mold is proposed in which the guide grooves are made in semi-matrix, and the symbol HVAN0101 is equipped with columns placed under the plane of the semi-matrix slot perpendicular to the slot

На фиг. 1 1зображана форма в раскрытом положении; на фиг. 2 - селение по А-А на фиг. 1 в момент удалени издели .FIG. 1 1 shows the form in the open position; in fig. 2 - settlement according to A-A in FIG. 1 at the time of removal of the product.
Литьева форма содержит неподвижную полуформу 1 и подвижную полуформу, включающую раздвижные полуматрицы 2, размещенные в обойме 3, формующий поднутреиние знак 4 с колонками 5, размещенными в пазах 6 полуматриц, пуансон 7 и штыри, 8.Casting form contains a stationary half-form 1 and a movable half-form, including sliding semi-matrix 2, placed in the holder 3, forming the undercut sign 4 with columns 5, placed in the slots 6 semi-matrix, punch 7 and pins, 8.

давлением. При раскрытии формы полуматрищы под действием щтырей расход тс в стороны, и одновременно из издели извлекаетс зна-к за счет перемещени его колонок по направл ющим пазам по)лумат1риц. Предложенна форма позвол ет изготавливать в изделии поднутрени , расположенные в любом направлении в плоскости разъема полуматриц .pressure. When the shape of the semi-matrix is opened under the action of the plugs, it is dispersed to the sides, and at the same time the sign is removed from the product by moving its columns along the guide grooves along the length of the matrix. The proposed form permits the production of undercuts in the product, which are located in any direction in the plane of the semi-matrix connector.
