Description

[Detailed explanation of the idea] (Industrial field of use) The present invention relates to a cooling tank device.

(Prior Art) It is widely known that a die-cast product is guided into a water tank by a conveyor, and the cast product is cooled by cooling water in the water tank.

Incidentally, during this cooling process, burrs and the like are removed from the as-cast product, and the burrs and the like accumulate at the bottom of the water tank.
Therefore, if a suitable amount of burrs and the like accumulate in the water tank, they must be removed. Conventionally, one method for this purpose has been to drain the cooling water in the tank and discharge the burrs and the like accordingly. However, in this case, the burrs and the like may form so-called bridges and block the discharge hole, which poses a problem in removing the burrs and the like.

(Purpose) The present invention is intended to solve the above problems, and its purpose is to easily remove burrs and the like.

(Structure of the invention) In order to achieve the above object, in the present invention, a bottomed cylindrical outer tank for storing cooling liquid is fixed to the base, and the opening of the outer tank is directed upward. a first container that supports an inner tank that is housed and has a hole bored in its wall so that it can be moved in and out of the outer tank;
Each end of a cylinder mechanism for positioning the inner tank in either position or a second position for inverting the inner tank is pivotally connected, and the chute is faced to the opening of the inner tank in the second position, A weir plate is disposed in the discharge path area of the chute at a predetermined distance from the discharge path surface of the chute.

With the above configuration, burrs and the like can be easily removed to the chute by inverting the inner tank.

Further, since the chute is provided with a weir plate, even if a product is accidentally thrown into the chute together with burrs, the product is stopped by the sheath plate and only the burrs etc. are removed.

Furthermore, since the device of the present invention is of the so-called batch type, the space used can be extremely small.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 and 2, reference numeral 1 denotes a base, and an outer tank 2 is fixed to one end side of the base 1 (on the right side in FIG. 1). This outer tank 2 has a cylindrical shape with a bottom, and cooling water as a cooling liquid is stored in the outer tank 2. An inner tank 3 is housed within the outer tank 2. The inner tank 3 has a cylindrical shape with a bottom, and the wall forming the inner tank 3 is provided with communication holes 4 as a plurality of holes that communicate the inside of the inner tank 3 with the inside of the outer tank 2. . Further, a projecting piece portion 5 is provided at the upper end portion of this inner width 3, and this projecting piece portion 5
The shaft 7 is attached to the projecting piece 6 provided at the upper end of the outer tank 2.
It is rotatably supported through.

A support column 8 is erected on the other end side of the base 1 (on the left side in FIG. 1). A cylinder mechanism 9 is pivotally attached to the upper end of this column 8, and a piston rod 10 of this cylinder mechanism 9 is pivotally attached to the protrusion 5. When the piston rod 10 of this cylinder mechanism 9 is extended, the first piston rod 10 accommodates the inner tank 3 in the outer tank 2 as shown in FIG.
It has a function of determining the position and determining a second position at which the inner tank 3 is reversed as shown by the imaginary line in FIG. 1 during contraction.

The chute 11 faces the opening of the inner tank 3 in the second position. That is, shoot 11
is fixed to the base 1 substantially below the opening of the inner tank 3 in the second position, and the chute 11 has a discharge path surface 1 of the chute 11 in its discharge path area.
A weir plate 13 is provided at a predetermined distance from 2. This predetermined distance is determined depending on the objects to be separated.

In addition, 14 is an unloading device, 15 and 16 are inner tank 3.
and a guide member provided on the chute 11, respectively.

Next, the effect will be explained using cooling treatment of a die-cast cast product as an example.

It is assumed that the piston rod 10 is extended as shown in FIG. 1, the inner tank 3 is housed in the outer tank 2, and the outer tank 2 stores cooling water.

Freshly cast product 17 filled with heat
is transported to the outer tank 2 by the carrying-out device 14 and cooled by cooling water in the outer tank 2. During the cooling process, burrs, etc. 18 of the as-cast product 17 fall into the outer tank 2, but since the inner tank 3 is housed in the outer tank 2, the burrs, etc. 18 fall into the inner tank 3. Collects at the bottom. When the cast product 17 is cooled to a predetermined temperature, it is transported from both tanks 2 and 3 to the outside by the transport device 14.

When the cooling process for the as-cast product is repeated several times and a suitable amount of burrs etc. 18 accumulates in the inner tank 3, the hydraulic cylinder mechanism 9 is activated and the piston rod 10
is shortened to indicate the inner tank 3 as shown by the imaginary line in Figure 1.
in the counterclockwise direction in Fig. 1 with axis 7 as the center.
Rotate 110°. As a result, the inner tank 3 is turned over,
The burrs, etc. 18 in the inner tank 3 are disposed of into the chute 11. At this time, if the as-cast product 17 accidentally falls into the inner tank 3, the as-cast product 17
Even if it is put into chute 11,
3 faces the conveyance path area of the chute 11 at a distance from the conveyance path surface 12 of the chute 11 that allows burrs and the like to pass through, but prevents the casting product 17 from passing through, so that the cast product 17 faces the conveyance path area of the chute 11. 13 will be stopped.

(Effects of the Invention) As is clear from the above description, the present invention can easily remove burrs and the like without causing the problem of clogging the discharge hole.

Furthermore, even if the product is accidentally removed along with the burrs when removing burrs, etc., since the chute is provided with a baffle plate, removal of the product can be prevented and only the burrs can be removed.

Furthermore, since the device of the present invention is a so-called batch type, the space used can be extremely small.
