Abstract

Изобретение относитс  к литейному производству, в частности к машинам дл  изготовлени  безопочных форм объемным прессованием, и может быть использовано в единичном, мелкосерийном и крупносерийном производстве. Целью изобретени   вл етс  повышение равномерности уплотнени  изготавливаемой формы. Устройство дл  изготовлени  безопочных форм объемным прессованием содержит формовочную камеру 3 с подвижными стенками , прессовый стол 1, пуансон 2 и компресирующую рамку 10. Устройство позвол ет повысить качество формы за счет повышени  плотности по всем сечени м. Это достигаетс  тем, что компенсирующа  рамка 10 устанавливаетс  на формовочную камеру и имеет отверстие , площадь которого не более площади формы в плане, в которой перемещаетс  пуансон 2 высотой больше высоты компенсирующей рамки. 3 илThe invention relates to a foundry, in particular, to machines for the manufacture of flaskless molds by volumetric extrusion, and can be used in single, small-scale and large-scale production. The aim of the invention is to improve the uniformity of compaction of the form produced. The device for making non-flask molds by volumetric pressing comprises a molding chamber 3 with movable walls, a press table 1, a punch 2 and a compression frame 10. The device improves the quality of the mold by increasing the density over all sections. This is achieved by compensating the frame 10 on the molding chamber and has a hole, the area of which is no more than the area of the form in the plan, in which the punch 2 is moved more than the height of the compensating frame. 3 silt
