）。Conventionally, after casting a casting, it is necessary to remove the sprue, runner, etc., as well as the core sand, which is generally done by hitting with a hammer or by drilling with a chisel. Starting with the work, core sand was removed by applying vibration using a shakeout machine or by the core knockout method, that is, by holding the casting product between a pie break and a clamp cylinder. The above method does not pose a problem for cast products that are small or have a simple internal shape, but in the case of cast products that have a complex internal shape, such as cylinder heads or manifolds, the energy efficiency of sand removal, There are many problems in the energy propagation method and other problems, and the disadvantage is that it takes a long time to remove the core sand, and it is difficult to remove the core sand. As a means to solve the above-mentioned drawbacks, a means has been disclosed for efficiently removing core sand from a casting product such as a cylinder head by imparting a vibrating area Y to the casting product at the same time as it rotates (for example, JP-A No. (See Publication No. 51-71226).

う問題点がある。The problem with the above-mentioned core sand removal device is that it cannot be applied to many types of casting products because the vibration impact transmission position to the casting product is fixed and the frequency and impact force are also constant. There is a point. In addition, especially for materials whose casting temperature is relatively low, such as light alloy castings,
There are cases where the strength of the core remains almost the same as before casting without collapsing, making the core sand removal work even more difficult.

The object of the present invention is to provide a casting core sand removal device that is capable of removing sand from a foundry.

する。D. A plurality of vibration impact generators facing the other face plate are arranged on one of the face plates so that the vibration frequency and impact force can be independently controlled and the position of vibration impact transmission to the cast product is variable.
という技術的手段を採用した。A technical method was adopted.
次に第２の発明においては、前記第１の発明における構

ｉＭ壊除未除去作用がある。With the above configuration, for example, if a cast product is attached to one face plate and a vibration shock is transmitted to the cast product using a plurality of vibration shock generators provided on the other face plate, the core sand will collapse and fall. This removes the core sand. Since the casting product rotates together with the shaft at the same time as the vibration impact is transmitted, the core sand can be smoothly discharged and removed from the baseboard portion forming the core. In addition, by making the frequency and impact force of multiple vibration shock generators and the position of the vibration impact transmission to the cast product variable, it is possible to create a resonance condition that corresponds to the cast product, and the core sand can be removed in a short time. j
iM has a non-destructive action.

の取付は取外しが容易となる。With the above configuration, the casting product from which the core sand is to be removed is fixed to the end face of the face plate 8 in FIG. Move the support member 3 to the left and use the air hammer 19
A portion of the hammer (20t) is brought into contact with the casting product. In this case, the compact cylinder 13 is operated to bring the movable element 14 into contact with the bearing 4 to prevent rotation of the shaft 6 in the horizontal plane. Further, when a cast product is to be fixed to the face plate 8, it is preferable to operate the cylinder 15 to bring the rod 16 into contact with the locking piece 17 to prevent rotation of the shaft 6 and the face plate 8. After the casting product is fixed, the operation of the cylinder 15 is stopped, the loft 1G is released from the locking piece 17, and the air hammer 19 is released via the compressed air pipe 23.
is actuated to transmit vibration and impact forces to the casting product by the hammer portion 20. On the other hand, if the shaft 7 is rotated via the pulley 22 by the drive of the motor 21, since the support member 3 is pressed to the left as described above, the face plate 8 to which the cast product is fixed and the shaft 6 will also rotate at the same time. . Therefore, the core sand in the casting product is removed by air hammer 19.
The material collapses due to the vibrations and impact forces caused by it, and at the same time, by rotating around the axis of the shaft 6.7, it is discharged and removed from the hollow opening of the baseboard or casting product forming the core. The discharged core sand is transported to a predetermined processing facility by a known transport means (not shown). After the core sand has been discharged and removed, the support member 3 is moved to the right, the cast product is removed from the face plate 8, and the next cast product is attached. In this case, when the vertical shaft 11 is rotated, for example, by 90'' via an actuator (not shown) with the operation of the compact cylinder 130 stopped and the mover 14 removed from the bearing 4 in FIG. Since they rotate together and their end faces face forward, it is easy to install and remove the cast product.

The vibration frequency and impact force of the two air hammers 19, 19 and the hammer part 20, 20 are configured to be variable independently, and the vibration and impact transmission positions to the cast product are variable. A resonance condition corresponding to the cast product can be created, and the collapse of the core sand can proceed in a short period of time.
