Description

Изобретение относитс  к области литейного производства, в частности к устройствам дл  нодпрессовки и формировани  литниковых чаш при изготовлении литейных форм на формовочных машинах.The invention relates to the field of foundry, in particular, to devices for pressing and forming runner bowls in the manufacture of molds on molding machines.

Известные зстройства, включаюш;ие плиту с грузами, на которой установлена подвижна  рамка с модел ми литковой чаши и сто ка, имеют существенный недостаток, заключающийс  в том, что при работе образуетс  слой спрессованной формовочной смеси между рабочей полостью формы и моделью сто ка.Known devices, including a slab with weights, on which a movable frame with a model of a casting bowl and a stack is installed, have a significant disadvantage in that a layer of compacted molding sand is formed during operation between the working cavity of the mold and the model of the stack.

Дл  устранени  указанного недостатка предложено описываемое устройство, отличающеес  от известного тем, что модель сто ка выполнена подпружиненной относительно рамки и подвижной относительно модели литниковой чаши.In order to eliminate this drawback, the described device has been proposed, which differs from the well-known one in that the stand model is spring-loaded relative to the frame and movable relative to the model of the runner bowl.

На фиг. 1 изображено описываемое устройство дл  подпрессовки и формировани  литниковых чаш; на фиг. 2 - то же, в рабочем положении, разрез.FIG. 1 depicts the described apparatus for pressing and forming runner bowls; in fig. 2 - the same, in the working position, cut.

Устройство состоит из плиты 1 с грузами 2, на которой установлена рамка 3 с модел ми чащи 4 и сто ка 5, и пружин 6.The device consists of a plate 1 with weights 2, on which a frame 3 is installed with models of bag 4 and stand 5, and springs 6.

Устройство при помощи цепей или тросов 7 подвешиваетс  через скобу 8 на крюк тельфера , при помощи которого устройство устанавливаетс  на литейную форму 9.The device is suspended by means of chains or cables 7 through a hook 8 on a hoist hook, with which the device is mounted on a mold 9.

Вначале на форму 9 ложитс  плита / с грузами 2, а затем по направл ющим 10 опускаетс  рамка 3 с модел ми 4 и 5. При этом модели сто ка 5 своими концами касаютс  модели //.First, a plate / with weights 2 is placed on the form 9, and then along the guides 10 a frame 3 is lowered with models 4 and 5. At the same time, the models 5 with their ends touch the model //.

При встр хивании рамка 3 с модел ми 4 перемещаетс  относительно неподвижных моделей сто ка 5 за счет пружин 6.When shaken, frame 3 with models 4 moves relative to fixed models of stand 5 by means of springs 6.

Модели литниковой чаши 4 выполнены пустотелыми , чтобы формовочна  смесь, проникающа  через зазоры между модел ми 4 и 5, не уплотн лась и не создавала бы дополнительных нагрузок на модели сто ка 5 при встр хивании. Внутри моделей литниковой чаши 4 дл  прочности выполнены ребра жесткости (на чертел :ах не показаны).The models of the gating bowl 4 are hollow, so that the molding mixture, which penetrates through the gaps between models 4 and 5, does not condense and does not create additional loads on the model of stand 5 upon shaking. Inside the models of the gating bowl 4, stiffening ribs are made for durability (in dash: ah, not shown).

Предмет изобретени Subject invention

Устройство дл  подпрессовки и формировани  литниковых чаш при изготовлении литейных форм на встр хнвающих формовочных мащинах, включающее плиту с грузами, на которой установлена подвижна  рамка с модел ми литниковой чаши и сто ка, отличающеес  тем, что, с целью уменьшени  образовани  спрессованного сло  между моделью сто ка и рабочей полостью литейной формы, модель сто ка вынолнена подпружиненной относительно рамки и подвижной относительно модели литниковой чаши.A device for pre-pressing and forming gating bowls in the manufacture of casting molds on embedded molding molds, including a slab with weights on which a moving frame with gating bowl models and a stand is installed, characterized in that, in order to reduce the formation of a pressed layer between the model ka and the working cavity of the mold, the stand model is made spring-loaded relative to the frame and movable relative to the model of the runner bowl.
