SRI 2 and detachable panels 3, then the first and second sections 6 are deployed relative to the axis i, the guide spacking device 14, c. which is introduced by non-solvents-electrodynamics, and the first layer of metggl is poured, the crystallization iiocne — which is turned over by the upper section of the lower section of m 2. Then the invention relates to a special electrometer: lurgy, specifically to molds for casting shaped blanks.

The aim of the invention is to expand the technological capabilities of the mold.

Figure 1 shows the proposed mold; Fig. 2 shows the same, with the upper section opened; and fig. Z-id A in Fig. I.

The mold contains a pallet 1, on which the lower sections 2 and the pile 3 are installed, Pa of the lower sections are fixed to the hinge axes A, on which the upper section 6 is mounted by means of svcpsy 5. On the last set the Eel. 7 axes on which are fixed levers 8 with handles 9 m stops (Oh,

Brackets II are fixed to sections 2, in which longitudinal grooves 12 are made (FIG. 3). Panel 5 is installed drain pipe 13.

The mold operates as follows: 11D1N.

The lower sections 2 and panels 3 are installed on the pallet 1, then the upper sections 6 are deployed about axis 4 (Fig. 2). The slag bath 14 is induced in the mold cavity, the first layer 15 metal is poured, the non-consumable electrodes 16 are lowered into the oshakovy bath , and these operations are performed under conditions of free access to the working cavity of the mold. Non-consumable electrodes provide a uniform, technologically justified mode of heating the entire volume of the slag bath 14, which is not a condition for smelting stamp pagots since their lower parts are of high quality, like metal.

A second metal layer is added and a smaller number of -18 electrodes are introduced, which heat the donkey bath 14 until the metal layer 17 is fully crystallized. The mold provides a metal in the lower part of the workpiece, from which the die is made with an engraving in the lower part. 3 il.

on which an engraving of the future stamp is formed.

After crystallization of the first layer 15, non-consumable electrodes 16 are taken out. d t from the mold cavity. The levers 8 with the handle 9 turn the upper sections 6, fastened with the links 5 about the axis 4 (figure 1). Then the lever 8 is inserted into the groove 12 of the bracket 11 and under the action of the force on the handle 9, the lever 8 is further moved down along the groove 12 until the upper section 6 is tightly pressed to the lower section 2.

After fixing the upper sections 6 in the working position (Fig. 1), portions of metal of the second stage are filled with 17, while the molten metal of the second layer lifts the slag bath 14, which occupies the tank formed by the upper sections 6, whose cross section is smaller than the tank formed by the lower sections, therefore, with a constant volume of slag 14, its height increases. Upon reaching the oshakovaya bath 14 of the draining nozzle 13, it is poured out through the aforementioned nozzle 13 and its height is set at a technologically reasonable value.

Non-consumable electrodes 18 (FIG. 1) are lowered into the slag bath 14, the number of which is less than that of the electrodes 16. Next, electrical heating of the slag bath 14 and crystallization of the second metal layer 17 are performed.

The proposed mold allows melting of high quality multilayer shaped ingots, the bottom section of which is larger than the cross section of the ingot.
