It is made in the form of a two shoulders lever pivotally mounted on the axis 14. The axis 14 is rigidly mounted in the housing 1 parallel to the mounting plane 2 of the mold. The two-arm lever is spring-loaded with a spring 15 so that one of its shoulders is pressed against the plane of the rotary half-mold 5. The latch 16 with the needle grip 17 is pivotally mounted on the axis 4 and serves to withdraw the needle from the working grooves of the rotary half-mold 5. The law of movement of the latch 16. is determined by the fist profile (not shown) with which this latch interacts.

Устройство работает следующим образом.The device operates as follows.

В положении приема игл поворотная полуформа 5 занимает горизонтальное положение. В этот момент специальным устройством иглы вводятся в рабочие пазы полуформы 5, где удерживаются фиксатором 16. После этого от соответствующего кулака -через рычаг 9 и зубчатые секторы 10 и 11 поворотная полуформа 5 получает движение, т.е. начинает поворачиваться вокруг оси 4 до тех пор, пока не будет обеспечено плотное смыкание полуформы 5 с Неподвижной полуформой. 3. В этот момент подвижная торцовая стенка ’ (не показана) прижимается к полуформам 3 и 5, образуя вместе с формообразующими поверхностями этих полуформ литейную полость пресс-формы. После подачи порции расплава в литейную полость, его затвердения и Удаления литника подвижная торцовая стенка, отходит, а поворотная полуформа 5 начинает обратный поворот вок руг оси 4, возвращаясь в положение приема игл. Наличие выталкивателя 12 гарантирует вывод из неподвижной полуформы 3 готовой плитки, которая ( увлекается поворотной полуформой 5' и фиксатором 16.In the receiving position of the needles, the rotatable half-mold 5 occupies a horizontal position. At this moment, with a special device, the needles are inserted into the working grooves of the half-mold 5, where they are held by the latch 16. After that, from the corresponding fist, through the lever 9 and the gear sectors 10 and 11, the rotary half-mold 5 receives movement, i.e. begins to rotate around axis 4 until then, until it is ensured tight closure of the half-mold 5 with the Fixed half-mold. 3. At this moment, the movable end wall ’(not shown) is pressed against the half-molds 3 and 5, forming, together with the shaping surfaces of these half-molds, a mold cavity. After feeding a portion of the melt into the casting cavity, hardening it, and removing the gate, the movable end wall departs, and the rotary half-mold 5 begins a reverse rotation around the axis 4, returning to the needle receiving position. The presence of the ejector 12 guarantees the conclusion from the fixed half-mold 3 of the finished tile, which (is carried away by the rotary half-mold 5 'and the latch 16.

При обратном повороте поворотная полуформа'5 взаимодействует с плечом рычага, поворачивая его при этом вокруг оси 14.In the reverse rotation, the rotary half-mold'5 interacts with the lever arm, while turning it around axis 14.

Фиксатор 16 с игольчатым захватом 17, .прворачиваясь одновременно с полу формой 5 вокруг оси 4, в какой-то момент 'времени останавливается. При этом&глы, залитые в плитку, встреча ются- с игольчатым захватом 17 и выходят из рабочих пазов полуформы 5. В момент, когда поворотная полуформа занимает исходное положение, (положение криема игл), двуплечий рычаг, поворачиваясь вокруг оси 14, упирается в боковую поверхность плитки и сталкивает ее. После этого фиксатор 16 с игольчатым захватом 17 занимает исходное положение. Профиль кулака, который задает закон движения поворотной полуформы 5, подобран таким образом, что взаимодействие выталкивателя 13 с поворотной полуформой. 5 носит безударный характер, т.е. работа механизма происходит в спокойном динамическом режиме. При этом циклограмма работы механизма обеспечивает оптимальный режим, необходимый для отливки игольно-пластиновых изделий в плитки.The latch 16 with a needle grip 17, turning simultaneously with the floor form 5 around the axis 4, at some point in time stops. At the same time, the holes filled into the tile meet with a needle gripper 17 and exit the working grooves of the half-mold 5. At the moment when the rotary half-mold is in its original position (the position of the kriem of the needles), the two-arm lever, turning around axis 14, abuts against the side surface tiles and pushes her. After that, the latch 16 with a needle grip 17 takes its original position. The profile of the fist, which sets the law of motion of the rotary half-mold 5, is selected in such a way that the interaction of the ejector 13 with the rotary half-mold. 5 is unstressed, i.e. the mechanism operates in a quiet dynamic mode. At the same time, the cyclogram of the mechanism provides the optimal mode necessary for casting needle-plate products into tiles.

Кроме того, двуплечий рычаг в момент, когда поворотная полуформа 5 занимает положение для приема игл, расположен так, что не препятствует ввйду игл в рабочие пазы полуформы 5.In addition, the two-arm lever at the moment when the rotary half-mold 5 occupies a position for receiving needles is located so that it does not prevent the needles from entering the working grooves of the half-mold 5.

Таким образом, использование изобретения позволяет упростить конструкцию устройства и, следовательно,снизить его себестоимость в среднем на 10%, Например, использование предлагаемого изобретения на опытном экспериментальном производстве СПКТБ ТП принесет годовой экономический эффект 1250 руб.Thus, the use of the invention allows to simplify the design of the device and, therefore, reduce its cost by an average of 10%. For example, the use of the invention in the pilot experimental production of SPKTB TP will bring an annual economic effect of 1250 rubles.
