    The invention concerns the technical problem of providing a simple and reliable apparatus for separating castings (3) from moulds of sand or similar material at the end of a guiding track (1), on which the moulds with the enclosed castings are advanced step by step towards a knocking-out station. With a view hereto the apparatus comprises a number of possibly interchangeable claws (11), 11a equipped with vibrators which, when moved into the row of moulds, can penetrate the mould sand and be caused to enclose and pinch the outermost casting (3a), whereafter the claws are shifted back to the initial position in which the pair of tongs formed by the claws can open in order to deliver the casting (3a) for further treatment. The claws can be specially formed so asto retain possible core sand (14) in the castings.

    The invention relates to foundry, in particular to knocked out devices. A device for separating castings from beeopochny molds is known, comprising rod magnets arranged in a drive holder. A disadvantage of the known devices is its complexity and high cost. The closest to the proposed technical essence and achievable effect is a device for separating castings from horizontal stacks of flaskless molds mounted on rails, containing a manipulator placed at the open end of the stack of molds, and and casting dresser carrying a vibrator 2. The disadvantage of this the device lacks the possibility of separate removal of the core and filling mixtures. The purpose of the invention is to ensure reliable retention of the sintered core sand in the casting during the separation process. This goal is achieved by the fact that, in a device for separating castings from a horizontal stack, bezopochny molds mounted on rails containing a manipulator, placed at the open end of the stack, 1) and a casting extractor carrying a vibrator, an extractor with a vibrator mounted on the manipulator and made the form of a tick clamp, one of the halves of which is made in the form of a scapula. FIG. 1 shows the device in the initial position; in fig. 2 is the same in the initial stage of casting removal in FIG. 3 - the same, in the presence of a core in a casting, in FIG. 4 a gripper in the form of a blade; in FIG. 5, the device in FIG. 1, top view. FIG. 1-3 shows the output end of the conveyor 1, on which a mold consisting of several equal parts 2 with casting 3 is located at the location of each connection of 4 molds. On the guide rod 5, running parallel to the conveyor 1, a carriage 6 moves, which is a hinge 7 connect with holder the two parts, 8 and 9, joined together by the hinge 10; the axis of which passes perpendicular to the rod 5. Each of the two parts 8 and 9 of the holder contains one or more zatTpeHHbix rods 11 directed towards the open side of the outer part 2 of the form, while the free ends of the rods are slightly bent towards each other. The rods are equipped with vibrators 12, which may be electric, hydraulic, or pneumatic. Between the two protruding arms of the two parts 8 and 9 of the holder, there is a hydraulic i or pneumatic cylinder 13, which compresses and expands the tongs formed by Elements 8, 11 and 9, 11, respectively. FIG. 1, it has been assumed that the exterior of Form 2 is intact, although it may show signs of thermal damage at its front uncovered end. When it is necessary to remove the Extreme Casting 3, the carriage 6 is shifted to the left to the position, while the engine in FIG. 2. In this position, the rods-t1 pass through the outer part 2 of the form and through the connector -4 of the form, as a result of which the folded BHytpb ends of the rods extend slightly into the next part 2 of the form. Obviously, the ends of the rods will not be damaged in this case of casting 3, which must be removed, and in order for the same device to be used for casting 3 of a different type, the rods 11, as noted above, can be replaced with rods of another forms, or they can be adjusted in the vertical and transverse directions on two parts 8 and 9 of the holder. When the rods reach the position shown in FIG. 2, the working medium is supplied to the cylinder 13 under pressure, with the result that the lower part 9 of the holder is rotated slightly on the hinge 10 to the position shown in FIG. 3, in which the rods capture the casting 3, partially freeing it from the slitting part 2 of the mold. After that, the carriage 6 is retracted to the position shown in FIG. 1, carrying the casting 3, which can be fed for further processing, and the device is ready to perform a new operation. As shown in FIG. 2 and 3, the rods 1-1 can lead to a partial destruction of the outer part 2 of the mold, and when removing the casting, the mold pieces can fall onto the conveyor belt for reuse (if required) after appropriate processing. When conveyor 1 is made in the form of a grid or mesh, the molding sand pieces can fall down through the holes in the grid. As noted in FIG. Figure 3 shows castings 3 having one or more bottom-opening cavities formed by the respective rods 14 This mixture, until full sintering, the mixture of these rods should not be mixed with the molding mixture forming part 2 of the mold, therefore the lower glue 11 serves to keep the core mixture in cast until it is separated from the molding blow. In connection with this, the rod or rods 11 may be in the form of a blade (Fig. 4). The blades 15 cover the core hole at the base of the casting. In FIG. 5 shows the proposed device with greater productivity, since it contains two tools 16, which alternately remove subsequent castings from molds 2. Each tool contains two upper and two lower grippers 11 of the core type, of which only two upper ones are shown, and 1,554 tools are moved along a common guide rod 5 suspended from a vertical rotating frame 17, which can signal periodic rotation as indicated by the arrow. In this position, the left tool 16 is ready to remove the casting enclosed between the two parts of the 2 mold, while the right tool 16 has just delivered the previous casting. In one or several intermediate positions (not shown), this part of the casting is cleaned from the remaining mold sand particles, for example, with a metal brush or shot blasting, just as it can be freed from the core mixture and tested in various ratios. With such intermediate positions, the number of tools must be increased so that the tool is in the removal position at each intermediate frame position. In addition, in a separate device, cleaning and testing can be carried out, for example, on a rotating frame, to which castings are fed using tools, so the frame is quickly ready for the next operation.
