Description

[Detailed Description of the Invention] The present invention relates to a mold disassembly device. Usually, while the poured mold is vibrated on a disassembly vibrator,
When separating the product from the sand, the sand attached to the bottom of the product falls off immediately, but the sand on the top of the product does not come off easily, so it is necessary to apply vibration for a long time.

However, since vibration is applied for a long time without sand on the bottom surface of the product, problems such as dents occur on the product.

The present invention aims to solve these problems. The configuration of the present invention will be explained below based on examples. Reference numeral 1 denotes a conveyor that can be moved intermittently, and on the conveyor 1, a large number of poured vertical molds 2 are arranged adjacent to each other. 3

Further, in front of the lattice stand 21, a second vibrator 2 is provided.
2 are installed adjacent to each other, and the second vibrator 22 has a pedestal 25 on which a grate plate 23 having the same structure as the grate plate 7 of the first vibrator 6 is installed, and vibration motors 24 are attached to both sides. It has a structure in which it is elastically supported by a spring 26. In addition, the second vibrator 2
In front of the second vibrator 22, an oscillating conveyor 27 is installed adjacent to the second vibrator 22.
Reference numeral 28 denotes a product transport device that is provided so as to be able to reciprocate above between the reversing machine 14 position and the second vibrator 22 position. The structure includes a freely disposed trolley 30, a fixed claw 31 and a Daruma-type product pushing claw 32 attached to the lower surface of the trolley 30 at a predetermined interval in the traveling direction. Piston rod 3 of pusher cylinder 33 attached to the upper surface of rail 29
3a via a rod member 34,
By the operation of the pusher cylinder 33, the mold 2 is reciprocated on the running rail 29, the sand on the lower side has been shaken off, and the mold 2 is transferred from the reversing machine 14 onto the second vibrator 22, and the adhering sand on the upper and lower surfaces is removed. The shaken-off products can be extruded from the second vibrator 22 onto the oscillating conveyor 27 while being held by a fixed claw 31 and a product pushing claw 32.

Further, the product pushing claw 32 of the Daruma method is rotatably supported on a support shaft 36 via a support plate 35 on the lower surface of the cart 30, and a stopper member 37 is vertically provided on the back surface of the product pushing claw 32. and
The product extrusion claw 32 is prevented from rotating clockwise, and when the mold 2 transferred from the reversing machine 14 to the upper surface of the second vibrator 22 is returned by the trolley 30,
This prevents the product from being pushed by the product extrusion claw 32 and being returned to the top surface of the reversing machine 14 again. An oscillating conveyor 38 is installed below the first vibrator 6 and the second vibrator 22 via a hopper 39, and is capable of recovering cast sand that has been shaken off.

Next, the operation of the device configured as described above will be explained. In a state where the cart 4 is moved on the guide rail 3 and the first vibrator 6 is waiting on the extension line of the conveyor 1, the conveyor 1 is moved intermittently and the mold 2 at the end position of the conveyor 1 is moved to the first vibrator 6. When the object is dropped onto the top surface of the grate plate 7, the vibration motor 8 is activated to vibrate the mold 2 on the top surface of the grate plate 7, shake off the sand from the bottom of the mold 2, and close the gap between the grids of the grate plate 7. From there, it is collected into the hopper 39 through the space of the truck 4, and the pusher cylinder 11 is pushed out to move the truck 4 on which the first vibrator 6 is mounted to the mold transfer position on the near side in FIG. move it.

Next, the mold transfer cylinder 12 is pushed out to transfer the mold 2 on the upper surface of the grate plate 7 to the horizontal upper surface of the wing plate 17 via the mold transfer table 20, and the drive motor 19 is activated to rotate the reversing machine 14. 90 clockwise in the vertical plane with axis 16 as the fulcrum
When rotated, the mold 2 is held between adjacent blades 17 and turned over 180 degrees, so that the sand on the upper side of the mold 2 is positioned on the lower side. After reversing, the pusher cylinder 33 is retracted to move the trolley 30 and hold the mold 2 on the upper surface of the wing plate 17 between the fixed claw 31 and the product extrusion claw 32 through the lattice stand 21. After being transferred to the upper surface of the grate plate 23 of the second vibrating machine 22, the cart 30 is returned along the traveling rail 29 to the position above the reversing machine 14 by the pushing operation of the pusher cylinder 33, and the next newly sent Prepare for mold 2.

Note that when the trolley 30 returns, the product extrusion claw 3
2 is in contact with the mold 2 on the upper surface of the grate plate 23, and the support shaft 3
Since the mold 2 is rotated counterclockwise about the fulcrum 6, the mold 2 is not pushed back by the product extrusion claw 32. Meanwhile, during this time, the vibration motor 24 is activated to vibrate the mold 2 that has been moved to the upper surface of the grate plate 23 to shake off the sand located below the mold 2 and remove most of the sand that has adhered to the product. .

Thereafter, the pusher cylinder 33 is retracted again to move the truck 30, and the blade plate 1 of the reversing machine 14 is moved.
The next mold placed on the upper surface of 7 and newly sent is transferred to the upper surface of the grate plate 23 of the second vibrator 22 via the lattice stand 21 while being held by the fixing claw 31 and the product pushing claw 32. At the same time, the product placed on the upper surface of the grate plate 23 and from which most of the sand has been shaken off is sent onto the oscillating conveyor 27 and taken out. Further, the sand collected in the hopper 39 is conveyed and moved on an oscillating conveyor 38.

As is clear from the above explanation, after shaking off the sand adhering to the bottom of the product, the product was turned 180 degrees and the adhering sand on the top of the product was shaken off from the bottom of the product. It is now possible to shake off the adhering sand during the vibration time, improving productivity, and since the vibration operation is performed with sand always on the bottom of the product, it has the effect of not leaving dents on the product. The effect of contributing to this type of industry is significant.
