Description

I

The invention relates to foundry, in particular to casting in metal molds.

The purpose of the invention is the expansion of the technological capabilities of the machine.

FIG. Is a chill machine before pouring at the moment of filing an additive in a chill, general view; in fig. 2, section A-A in FIG. one; in fig. 3 - chill machine after entering the additive into the chill mold, general view; in fig. 4 - node .1 in FIG. 3

The device contains upper 1 and lower 2 half-molds, forming a cavity 3 in which the casting is formed, a mechanism for ejecting the casting 4, which contains an ejector plate 5, and a water-cooled ejector 6. On the side surface of the ejector, a channel 7 for entering additives 8 is made deaf from the end 9 of the ejector 6, forming the geometry of the casting. Part of the channel 7 from the end face 9 of the ejector is made along the radius (Fig. 4). On the plate 5, a mechanism 10 for supplying the additive 8 to the cavity 3 of the mold is installed.

The device works as follows.

After the metal is poured into the chill mold and its crystallization is completed, the mechanism for moving the upper half-form (not shown) is activated. The casting is released from the bottom half of the mold 2 and, together with the upper half of the mold 1, moves upwards. At the end of the course of the upper half-form, a komide is supplied to move the ejector plate 5. down. Ejector 6 removes casting from the top semi240992

Form 1 and it is removed from the work area, for example, using a receiving tray (not shown). After removal of the casting, the upper half-mold 1 moves downwards. The ejector plate 5 with the ejector 6 is at this time stationary relative to the half-form I. At the same time, the additive is fed, for example, in the form of a wire, through the cable 7 to enter the ejection additives ш w 6. When the upper half-form I is closed with the lower half-form 2, the ejector 6 is moved to its original position for filling (up), with

15 this results in the cut-off of a given dose of additive 11 when the ejector 6 interacts with the half-form. The prescribed dose of the additive 1t enters the cavity of the 3 chill mold. Thereafter

; jO there is another fill.

To homogenize the melt and evenly distribute the ingredients, if necessary, an electromagnetic rotator 12 can be switched on.

The use of the invention allows to expand the technological capabilities of the device, as a result of providing the possibility of using

30 ° chill molds with water-cooled, tubular, etc. pushers. The execution of the trout part of the deaf groove along the radius facilitates the introduction of any kind of additives: wire, imitation additives, liquid, etc. In addition, making the channel for inserting a groove fit on the side surface of the ejector is easier to manufacture (milling operation) than making a curved channel inside the ejector.
