Note that the arrows in the figure indicate the direction of movement of the mold 6 and the cast material 20.

Next, the operation of the device configured as described above will be explained. A mold extrusion plate (not shown) is raised, and the poured mold in the finished flask 7 that has been conveyed to a predetermined position is extracted upward, and the upper surface of the mold extrusion plate (not shown) is placed on the fixed transfer table 8, 1st
When positioned at the same height as the top surface of the shake-out machine 4, the traveling cylinder 16 is retracted,
The traveling cart 15 is moved to the right (in the figure), and the mold 6 on the upper surface of the mold extrusion (not shown) is pushed by the mold feed claw 17 and passed through the fixed transfer table 8 to the first
The rough material cast product 20 that has been transferred to the upper surface of the first shake-out machine 4 on the conveyance path 1 and from which the adhering sand on the upper surface of the second shake-out machine 4a has been removed is pushed by the rough material feed claw 18 and becomes a rough material. It is delivered to the bucket receiver 19. Thereafter, when the traveling cylinder 16 is reversely operated and the traveling carriage 15 is returned to the original position as shown in the figure, a drive device (not shown) is operated, and the first carriage with the first shakeout machine 4 fixedly supported on its upper surface is moved. 3 is moved to the front end of the first conveyance path 1 on the extension line of the first fixed transfer table 2, and at the same time, the second cart 3a, which firmly supports the second shake-out machine 4a, is also moved to the front end of the second conveyance path 1a. During this time, the mold 6 placed on the top surface of the first shake-out machine 4 is subjected to vibration and its mold shape is broken, and the raw material cast inside the mold 6 is exposed, and most of the casting sand is removed. The raw material is separated from the cast product, passes through a gap in the receiving plate member on the upper surface of the first shake-out machine 4 formed in a lattice shape, and is stored in a collection hopper located below through the through hole of the first truck 3. In this way, the rough cast material on the upper surface of the first shake-out machine 4, which has been separated from most of the attached sand, is transferred to the second shake-out machine via the first fixed transfer table 2 by the extrusion operation of the first conveying cylinder 9. It is transferred to the front upper surface of the out machine 4a. During this period, the new mold extracted from the finished flask 7 is transferred to the rear part of the first shakeout machine 4 through the same operation as described above by the contraction operation of the traveling cylinder 16. Subsequently, the first shake-out machine 4 and the second shake-out machine 4a are moved along with the first and second carts 3, 3a, respectively, to the rear end of each conveyance path 1, 1a by the reverse operation of a drive cylinder (not shown). It will be moved to the department. During this time, the rough casting placed on the upper surface of the second shakeout machine 4a was subjected to vibration, and some of the foundry sand adhering to its surface was completely shaken off. The molding sand passes through the gap between the grid-shaped receiving plate members on the upper surface of the second shake-out machine 4a, and is transferred to the second truck 4.
a It passes through a through hole drilled in the center and is accommodated in the collection hopper below. On the other hand, a new mold placed on the rear upper surface of the first shakeout machine 4 also
During the backward movement of the first shake-out machine 4, the internal rough casting is exposed due to vibration, and most of the molding sand is removed. Then, by the operation of the second conveying cylinder 10, the cast material is transferred from the first shake-out machine 4 to the second shake-out machine 4a via the second fixed transfer table 2a.
is transferred to the rear upper surface of the traveling cylinder 16.
As a result of the operation, the traveling carriage 15 is moved to the right (as shown in the figure), and a new mold is guided by the mold feed pawl 17 and transferred to the front upper surface of the first shakeout machine 4. On the other hand, the cast material 20 from which the adhering sand on the front upper surface of the second shake-out machine 4a has been completely removed is guided by the material feed claw 18 and delivered to the material bucket receiver 19. By repeating such operations, the sand adhering to the cast material is successively separated and removed.

If the molding sand can be sufficiently separated and removed by a short period of vibration, it is sufficient to stop the vibration of the second shake-out machine 4a and move the second cart 3a. Further, from the first conveyance path 1 to the second conveyance path 1
When transferring the mold to a, the mold may be held and transferred.

In short, the present invention involves arranging two shakeout machines with a length that allows two poured molds to be placed at an appropriate interval in parallel at an appropriate interval, and A shake-out machine is provided so that it can reciprocate by a distance of 1/2 the length of the shake-out machine, and a poured mold is transferred at both ends of the reciprocating movement of the two shake-out machines. The device is placed above the center of the reciprocating motion of the two shake-out machines, and a traveling trolley is provided so as to be movable and intersect with the two shake-out machines, and a mold is placed on the lower surface of the traveling trolley. Since the feed pawl and the raw material feed pawl are vertically installed at a predetermined interval in the traveling direction of the traveling cart, the shake-out time can be arbitrarily selected depending on the amount of sand attached to the raw material casting product. Therefore, it is possible to efficiently and completely separate and remove adhering sand without damaging the raw casting product.
