Description
качешш l установлены пальцы 15, взаимодействующие со скосами а рьгаага , В матрице выполнены износостойкие, нёкледкн 16;.the quality of the fingers 15 is installed, interacting with the bevels of the shaft, Wear-resistant, non-insulated 16 ;.
Форма работает следующим образом. После заполнени оформл ющей полости к необходимойвыдержкиформа раскрываетс по плоскости разъема. Рычаг 9, перемеща сь вместе с подвижной частью формы, взаимодействует скосами а с пальцами 15, и.рычаг, поворачива сь йа оси, отводит оформл ющий вкладыш 1О, освобожда отливку Пружина 11 прижимает рычаг 9 к упору 12 и удерживает его в отведенном положении. После раскрыти формы, во врем которого отливка освобо одаетс от oclioptvOiHющего вкладыща 10, происходит съем детали. выталкидающей системой.The form works as follows. After filling the decorating cavity to the required support, the mold is opened along the plane of the connector. Lever 9, moving together with the movable part of the mold, interacts with bevels and with fingers 15, and the lever, turning the axis, retracts the styling liner 1O, releasing the casting. Spring 11 presses lever 9 to the stop 12 and holds it in the retracted position. After the mold has been opened, during which the casting is freed from the ocliating insert 10, the parts are removed. ejector system.
При закрытии формы рычаг 9, взаимодейству с обоймой 2, поворачивает с вокруг оси н. перемещает вкладьп 1.0 в исходное йоложение.When closing the form of the lever 9, interacting with the holder 2, turns with around the axis n. moves the investment 1.0 to the original position.
Так как ход рычага 9 и соответственно вкладьша 10 незначителен по сравнению с радиусом траектории движешга вкйадьпна {практически в 50-80 раз меньше), то дуга, по которой он движетс , близка к хорде и кривизна ее вполне компенсируетс величиной литейного уклона на формообразуюМйх элементах вкладыша, 10.Since the stroke of the lever 9 and, respectively, the insertion of 10 is insignificant compared to the radius of the trajectory of the engine is almost 50-80 times smaller, the arc along which it moves is close to the chord and its curvature is completely compensated by the magnitude of the foundry slope on the shape of the liner. , ten.
Экономический эффект от внедрени такой конструкхщи формы за счет упрощеш1Я ее, увеличени надежности работы и уменьшени эксплуатационных расходов по одному наименованию издели массового производства составл ет 5бОО руб.The economic effect from the introduction of such a form construction due to its simplicity, increasing the reliability of work and reducing the operating costs for one item of the mass production product is 5 rubles.
