Description
Изобретение относитс к перера- . ботке пластмасс в издели , в част ности к формам дл изготовлени изделий со стержневыми впускными литниками методом лить под давлением.The invention relates to recycling. processing plastics into products, in particular, to molds for the manufacture of products with core inlets by injection molding.
Известна литьева форма дл полимерных изделий, содержаща неподвижную и подвижную плиты, литниковую плиту и механизм отделени литниг : АовГП.A casting mold for polymeric products is known, comprising fixed and movable plates, a runner plate, and a separation mechanism: AOGVP.
Однако в известной литьевой форме механизм отделени литников вьшолнен в виде поворотного диска, один из концов которого жестко закреплен в зубчатом секторе. Такое конструктивное выполнение усложн ет -конструкцию формы.However, in the known injection mold, the mechanism for separating the gates is made in the form of a rotary disk, one of the ends of which is rigidly fixed in the toothed sector. Such a constructive implementation complicates the design of the form.
Наиболее близкой к предлагаемой по технической сущности и достигаемому эффекту вл етс литьева форма дл полимерных изделий, с механизмом отделени литников, содержаща неподвижную плиту, литниковую плиту,, нож дл отделени литников, устаноClosest to the proposed technical essence and the achieved effect is a mold for polymeric products, with a mechanism for separating gates, containing a fixed plate, gating plate, a knife for separating gates,
пенный с возможностью перемещени вдоль литниковой плиты, и механизм перемещени ножа, выполненный в виде ролика, взаимо ействующего с копиром , и пружины дл отведени ножа в исходное положение 2.foam that can be moved along the sprue plate, and a knife transfer mechanism, made in the form of a roller, interacting with a cam, and a spring for retracting the knife to its original position 2.
Однако наличие пружины делает работу формы ненадежной,так как под действием температурного режима пружина ослабевает.However, the presence of the spring makes the work of the form unreliable, as the spring weakens under the effect of the temperature regime.
Цель изобретени - повьшение надежности работы формы.The purpose of the invention is to increase the reliability of the form.
