Description
Изобретение относитс к литейному производству и может быть использовано дл изготовлени изделий .с кристаллизацией под давлением. Известна пресс-фоЕ ла дл штамповки жидкого металла, содержаща плиту креплени формообразующего элемента обойму, распрессовочные брусь и шты ри. Дл облегчени съема отливки с формообразующего элемента плита креплени выполнена с выступами, взаимо действующими с распрессовочными брусь ми, и с отверсти ми под распрессовочные штыри, а отверстие в верхней части обоймы выполнено с обратным конусом 1. В момент прессовани между обоймой и вкладышем образуетс зазор, в который запрессовываетс расплавленный металл, затрудн ющий процесс извлечени издели из формы. При рае прессовке необходимо применение ручHtjx операций на установку распрессовочных брусьев и штырей, что делает невозможным использование таких пресс-форм в автоматическом режиме работы прессового оборудовани и при работе в поточной линии. Известна также форма дл лить с кристаллизацией под давлением, котора содержит конусную матрицу с вертикальным разъемом, установленную в обойме, пуансонодержатель, пуансон и подвижную плиту с отверстием, раз-. мещенную под матрицей. Дл извлечени матрицы из обоймы форма передвигаетс по плите до совмещени с отверстием , а затем давлением пуансона матрица выпрессовьшаетс из обоймы 2 . Така вл етс наиболее близким к описываемому изобретению по технической сущности и достигаемому результату. Недостаток формы заключаетс в том, что дл освобождени матрицы требуютс двойной ход пресса и р д операций по перемещению формы по плите, причем одевание обоймы .осуществл етс с помсадью тельфера. Все это снижает производительность труда Цель изобретени - повышение производительности труда. Цель достигаетс тем, что форма снабжена подпружиненными захватами, шарнирно закрепленными на пуансонодержателе , при этом на обойме выполнены выступы, вход щие в зацепление с захватами.The invention relates to foundry and can be used for the manufacture of products with crystallization under pressure. A known press foil for punching a liquid metal, comprising a fastening plate of a forming element, a yoke, decompression bars and pins. To facilitate removal of the casting from the forming element, the fastening plate is made with protrusions interacting with the pressing bars and with holes for the pressing pins, and a hole in the upper part of the cage is made with a reverse cone 1. At the time of pressing, there is a gap between the yoke and liner, in which molten metal is pressed in, making it difficult to remove the product from the mold. In case of pressing, it is necessary to use manual operations to install press-out bars and pins, which makes it impossible to use such molds in the automatic mode of operation of the pressing equipment and when operating in a production line. Also known is a mold for casting with crystallization under pressure, which contains a tapered matrix with a vertical connector, mounted in a holder, a punch holder, a punch and a movable plate with a hole, section. placed under the matrix. To remove the die from the holder, the mold is moved along the plate until it is aligned with the hole, and then the die is pressed out of the sleeve 2 by pressing the punch. This is the closest to the described invention to the technical essence and the achieved result. The lack of form lies in the fact that in order to release the die, a double stroke of the press and a number of operations to move the mold around the plate are required, and the dressing of the sleeve is carried out with the hoist. All this reduces labor productivity. The purpose of the invention is to increase labor productivity. The goal is achieved by the fact that the mold is provided with spring-loaded grippers that are hinged on the punch holder, while on the holder there are protrusions that engage with the grippers.
