Claims (1)

one The invention relates to foundry production, in particular, to casting on melted models. The goal is to reduce the model rejects and expand the casting range. The drawing shows a mold, a section. The mold contains movable and stationary dies I and., Which form the model 3 model's onboard contour, a hollow rod D that forms the internal contour of the model, a pusher plate 5 with a tubular pusher 6 in Hei i to remove the model, a cylindrical pusher 7 connected with itit 8 with tubular pusher 6 and serves for de-fusing part of the internal cavity of the model and transferring the pushing force to the model from the plates of 5 tolkani through the pipes - 20 containing the imbedded and immobile) pusher 6, In the matrix 1, a rod 9 is installed, forming a technological opening in the model to allow the deep cavity of the mold to communicate with the atmosphere when opening the mold. The grooves 4 are made in the rod 4, the length of which is equal to the required motion of the pusher plates, and the width is equal to pin 8, The mold works as follows in a way. After pressing the model composition and the necessary shutter speed for its curing, the mold is opened. The rod 9 departs along with the movable matrix 1, as a result of which the deep cavity of the model is in communication with the atmosphere. Pushers 25 thirty 35 matrix, rods, cylindrical and tubular pushers, the latter being installed in the pusher plate, characterized in that, in order to reduce scrap and expand the casting range, one of the rods for shaping the inner bore is hollow, has grooves for the pushers to move, In this case, the tubular and cylindrical pushers are rigidly interconnected, and in the movable matrix there is additionally installed a stegneg for forming a technological opening, which serves to open the mold for connecting a deaf deep cavity form1-1 atmosphere. 2, The mold according to claim 1, 1, and TL is such that the tubular mains 11 move the plate 5, the pusher, Q and the cylindrical pushers are connected to the tubular one installed by means of a pin, and the hollow rod, the pusher 6, which simultaneously located between them VISH1PI Order 272 / J3 Circulation 741 no.Tn2icju) e Polyp.product tsr- i v.o, Uzhgorod, st.

Closing the mold is carried out in the usual manner, 1C. f-ly, 1 ill. rigidly connected by moving the groove 10 (rod 4) pin 8 to the cylindrical pusher 7, removing the model from the fixed matrix 2 and removing it from the rod 4, closing the mold and returning the pushing plates in the usual way. The invention allows to expand the range of castings produced by casting on melted models, and to reduce the scrap due to the possibility of obtaining high-quality models with deep blind holes. Formula acquisitions 1, The mold of the mold is properly molded for melted models. matrix, rods, cylindrical and tubular pushers, the latter being installed in the pusher plate, characterized in that, in order to reduce scrap and expand the casting range, one of the rods for shaping the inner bore is hollow, has grooves for the pushers to move, In this case, the tubular and cylindrical pushers are rigidly interconnected, and in the movable matrix there is additionally installed a stegneg to design a technological opening, which serves to open the mold for connecting a deeper deep cavity form1-1 atmosphere.
