Изобретение относитс  к литейному производству , в частности к технологии изготовлени  полуформ.The invention relates to foundry, in particular, to the technology of making half-molds.

Известен способ изготовлени  полуформ вертикальным двусторонним прессованием, включающий заполнение опоки смесью и прессование. Недостатком этого способа  вл етс  то, что верхний отпечаток получаетс  методом пр мого прессовани  и, следовательно , он имеет более низкое качество, чем нижний .A known method of manufacturing half-molds is vertical two-sided pressing, including filling the flask with a mixture and pressing. The disadvantage of this method is that the top print is obtained by direct pressing and, therefore, it has a lower quality than the bottom one.

С целью повышени  качества отпечатков в полуформе предложен способ, по которому перед прессованием смеси опоку с подмодельными плитами поворачивают на 180°.In order to improve the quality of the prints in the half-mold, a method has been proposed that, before pressing the mixture, the flask is turned 180 ° before pressing the mold with the sub-model plates.

На фиг. 1-6 схематично показано изготовление безопочных форм по предложенному способу.FIG. 1-6 schematically shows the manufacture of flaskless forms according to the proposed method.

На нижнюю подмодельную плиту 1 устанавливают опоку 2 и засыпают в нее формовочную смесь. Верхнюю подмодельную плиту 3 устанавливают и закрепл ют таким образом, чтобы был обеспечен зазор между смесью иOn the bottom submodel plate 1 set the mold 2 and pour the molding sand into it. The upper sub-model plate 3 is installed and secured in such a way as to provide a gap between the mixture and

модел ми. Опоку 2 вместе с подмодельными плитами 1 к 3 поворачивают на 180° и при этом освобождают нижнюю подмодельную плиту, котора , зан в верхнее положение, под действием собственного веса проваливаетс  в ошоку, не отрыва сь от формовочной смеси. Затем плиты 1 и 3 перемещают навстречу друг другу в вертикальнОМ направлении и уплотн ют смесь. После извлечени  модельных плит из формы и :поворота ее на 90°, готова  форма выталкиваетс  из опоки 2.models mi. The flask 2, together with the sub-model plates 1 to 3, is rotated by 180 ° and, at the same time, the lower sub-model plate is released, which, in the upper position, under the action of its own weight, collapses into an oshoka, without separation from the molding sand. Plates 1 and 3 are then moved towards each other in a vertical direction and compact the mixture. After the model plates are removed from the mold and: rotated by 90 °, the ready mold is ejected from the flask 2.

Предмет изобретени Subject invention

Способ изготовлени  полуформ, преимущественно безопочных с двусторонним модельны .м отпечатко.м, включающий заполнение опоки смесью и двустороннее вертикальное прессование смеси модельными плитами, отличающийс  тем, что, с целью повышени  качества отпечатков в полуформе, перед прессованием смеси опоку с подмодельными плитами поворачивают на 180°.A method of making half-molds, preferably bezopochny with a double-sided model of fingerprints, including filling the flask with the mixture and bilateral vertical pressing of the mixture with model plates, characterized in that, in order to improve the quality of the prints in the half-mold, before pressing the mixture, the flask with the model plates is turned 180 °
