Description

CYLINDER DRIVING DEVICE OF DIECASTING COOLING APPARATUS USING PNEUMATIC CYLINDER AND COOLING DEVICE THEREOF}

The present invention relates to the cooling of die-cast castings, and more particularly, by using a pneumatic cylinder to fix the biscuits of the die-cast casting, and then driving the pneumatic cylinder of the apparatus for cooling the diecast casting in the air exposed state. An apparatus and a cooling apparatus of a diecast casting using a pneumatic cylinder which detaches and attaches a diecast casting when this cooling apparatus cools many diecast castings as it moves.

Die casting is a precision casting method in which molten metal is injected into a steel mold that is precisely machined to perfectly match the required casting shape to obtain the same casting as the mold. Products produced by die casting are called die cast castings. The temperature after casting of the die cast casting is cooled and solidified as 270 to 300 ° C. A general air-cooled cooling method is as follows.

1 is a view showing a shape in which a casting is mounted on a cooling jig for cooling a conventional die cast casting.

As can be seen in the figure, the casting 100 cast in the mold is cooled by air cooling in a state loaded on the jig 150. The upper surface of the jig 150 is shaped to correspond to the lower shape of the casting as shown in the figure so that the casting is stably loaded thereon.

Figures 2a and 2b is a view showing a shape that is forced cooling while moving the casting is mounted on the jig, Figure 2a is a view showing a shape that is cooled while moving the casting in the horizontal direction, Figure 2b is a vertical direction It is a figure which shows the shape which cools while a casting moves.

In FIG. 2A, the die cast casting 100 is moved through the horizontal roller 200 in a state where it is mounted on the jig 150. While the die cast casting 100 moves while being exposed to the atmosphere, a plurality of cooling fans 250 are installed on the upper portion of the roller 200, so that the die cast casting 100 moves through the roller 250. Forced cooling.

In FIG. 2B, the die cast casting 100 is moved in the vertical direction through the vertical roller 300 in the state of being loaded on the jig 150. A plurality of cooling fans 350 are installed on the side of the vertical roller 300 to force cooling while the die cast casting moves in the vertical direction.

In the conventional method of cooling such a diecast casting, the following problems are encountered.

That is, as shown in FIG. 1, since the shape of the jig 150 is determined according to the lower shape of the die cast casting 100, whenever the shape of the die cast casting 100 is changed, the jig 150 corresponding thereto is changed. This requires huge costs, time and effort.

In addition, as shown in Figs. 1 and 2A and 2B, when the die-cast casting 100 is loaded on the jig 150 by a robot arm or the like, a flaw may be generated by contact with the jig. In addition, since the die cast casting 100 is cooled while moving in the horizontal or vertical direction while being mounted on the jig 150, an impact may occur during the movement, and damage or damage to the casting 100 may be caused by the impact. This may occur.

In addition, as shown in FIG. 1, since the die-cast casting 100 is loaded on the jig 150, the upper portion of the casting, that is, the portion exposed more to air, is cooled faster and the lower portion of the casting is cooled relatively late. Balanced cooling becomes difficult.

In order to solve this problem, the applicant has filed a patent for the cooling device of the die casting as of January 8, 2008. In the present patent application, instead of placing a die cast casting on a corresponding jig and cooling it, a cooling apparatus of a die cast casting having a structure as shown in FIGS. 3A and 3B is proposed. The cooling device 400 includes a lower support 410 for supporting a die cast biscuit from below, a gripping jaw 420 formed at one end of the lower support 410, and a biscuit for pressing the lower surface of the biscuit. The pressing rod 430 supported by the upper portion, formed at one end of the pressing rod 430, the pressing jaw 440 for pressing the upper surface of the biscuit in pairs with the chuck 420, and the pressing rod 430 It comprises a pneumatic cylinder 450 coupled to the other end. On the other hand, the pneumatic cylinder 450 is fixed to the lower support 410 and the piston rod 455 is coupled to the other end of the compression rod 430. In addition, a hinge rod 460 is formed at a central portion of the lower support 410, and the hinge rod 460 is hinged to a central portion of the compression rod 430.

In addition, the bite jaw 420 has a sawtooth surface in order to increase the coupling force when the biscuit is fixed by the bonding jaw 440. This tooth shape may damage the lower surface of the biscuit 310 when the biscuit 310 is fixed, but it is not a problem because the biscuit 310 will eventually be discarded. In addition, the pressing jaw 440 may move smoothly to smooth the surface of the biscuit 310 to be easily contacted and fixed to the upper surface of the biscuit 310.
At this time, according to the expansion and contraction of the pneumatic cylinder 450, the distance between the two hinges of the pressing rod 430, that is, the hinge connected to the piston rod 455 and the hinge connected to the hinge rod 460 can not but change the compression rod ( In order for the 430 to operate smoothly, the pneumatic cylinder 450 is fixed to the lower support 410 by a hinge, the hinge rod 460 is fixed to the lower support 410 by a hinge, or the hinge rod 460 is It is apparent that the elastic material is configured to be elastically operated, and in FIGS. 3A and 3B, it is not shown in detail, but is schematically illustrated.

In this way, the biscuit 310 of the die-cast casting is disposed between the bleeding jaw 420 and the crimping jaw 440, and then the crimping jaw 440 is moved downward. At this time, both jaws are coupled to fix the biscuit 310 therebetween. Meanwhile, in order to move the pressing jaw 440 downward, one end of the pressing rod 430 moves downward. For this purpose, the other end of the pressing rod 430 should move upward. This is because, as shown in the figure, the hinge rod 460 is coupled to the center of the pressing rod, both ends of the pressing rod 430 is moved around the hinge rod 460, such as isiso.

As described above, the pneumatic cylinder 450 is fixed to the other end of the lower support 410 and the other end of the pressing rod 430 is coupled to the piston rod 455 of the pneumatic cylinder 450, so that the piston By the movement of the other end of the pressing rod 430 is moved in the vertical direction. When the piston rod 455 of the pneumatic cylinder 450 protrudes, the other end of the pressing rod 430 moves upwards to move the pressing jaw 440 attached to one end of the pressing rod 430 downward. 440 and the bite jaw 420 is coupled so that the biscuit 310 is fixed therebetween.

On the contrary, when the piston rod 455 of the pneumatic cylinder 450 is contracted, the other end of the pressing rod 430 moves downward, and the pressing jaw 440 coupled to one end of the pressing rod 430 moves upward. do. At this time, the pressing jaw 440 and the chucking jaw 420, which are coupled to each other, are released and the biscuits 310 fixed between them are released. This assumes that the diecast casting has finished cooling, and the diecast casting is moved to the next process and processed.

In order to cool the casting while the die casting casting cooling apparatus 400 described above is moved in the horizontal or vertical direction, air is supplied to and discharged from the pneumatic cylinder at the beginning of the cooling, so that the cooling apparatus removes the biscuits of the die casting casting. The castings are fixed so that after casting is finished, air is supplied to the pneumatic cylinder and discharged so that the cooling device depresses the biscuits.

In addition, in order for air to be supplied and discharged to the pneumatic cylinder at the start of cooling and at the end of cooling, the air supply and discharge device must be exactly matched to the air inlet and outlet of the pneumatic cylinder.

Accordingly, the present invention, in the cooling device for cooling the casting in a state in which the biscuits of the die cast casting is pressed and fixed using a pneumatic cylinder, driving the pneumatic cylinder to detach the die cast casting while moving the cooling device horizontally or vertically It aims to do it.

In addition, in the cooling apparatus for cooling the casting in a state in which the die-cast casting biscuits are pressed and fixed using a pneumatic cylinder, the air supply and discharge apparatus in a state in which the biscuits are fixed or released by supplying and discharging air to the pneumatic cylinders. Even if is removed from the pneumatic cylinder, the pneumatic cylinder maintains its current state.

In addition, the pneumatic cylinder and the air supply and discharge device are exactly matched when the cooling starts and the cooling ends.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. This embodiment is intended to facilitate the description of the present invention, but the technical spirit of the present invention is not limited to this embodiment. It can be seen that the technical idea of the present invention is limited only by the claims described below.

4A and 4B show a pneumatic cylinder equipped with a check valve in accordance with the present invention.

Check valves are valves that allow a certain flow of gas or fluid to flow in only one direction. 4A and 4B, it can be seen that check valves are provided on the upper and lower sides of the pneumatic cylinder, respectively. A piston 453 is installed between the check valves in the cylinder, and the piston transmits power to the outside through the piston rod 455.

FIG. 4A shows a state in which air is injected into the pneumatic cylinder 450 through the upper check valve A, and air existing in the cylinder is discharged through the lower check valve B. As shown in FIG.

At this time, since both valves (A, B) are check valves, when the air supply and discharge device is removed from both valves, the position of the piston 453 is maintained in the current state. That is, the state of FIG. 4A is maintained. In other words, in the state where the piston 453 has reached the bottom dead center in the pneumatic cylinder, the piston rod 455 contracts to the inside of the cylinder and is maintained with the biscuit 310 of the die cast casting released as shown in FIG. 3A.

On the other hand, Figure 4b shows a state in which air is injected into the pneumatic cylinder 450 through the lower check valve (B) and the air existing in the cylinder is discharged through the upper check valve (A). At this time, since both valves A and B are check valves, when the pneumatic cylinder driving device is removed from the valves, the piston 453 maintains its current state.

When such a check valve (A, B) is applied to and used in the pneumatic cylinder 450 of the cooling device according to the present invention will operate as follows.

5 is a view showing a pneumatic cylinder drive device for supplying and discharging air to the pneumatic cylinder of the cooling device according to the present invention.

As shown in the figure, the pneumatic cylinder drive device 500 is a solenoid valve 520 connected to the air source 510, and the air supplied through the solenoid valve 520 check valve (A, B) of the pneumatic cylinder A docking port 540 with an air nozzle 530 for connection to the docking port and a docking port for accessing the docking port to the pneumatic cylinder 450 to allow the air nozzle 530 to be inserted into the check valves A and B. Drive cylinder 550.

In order to fix the die-cast casting by operating the pneumatic cylinder 450 of the cooling apparatus according to the present invention, the docking port drive cylinder 550 is operated to move the docking port 530 toward the pneumatic cylinder 450. After that, the air nozzle 530 of the docking port is pushed into the check valves A and B of the pneumatic cylinder, so that air is supplied to the pneumatic cylinder 450 through the check valves A and B, and to the pneumatic cylinder 450. To let air out.

In this case, a method of connecting the air nozzle 530 of the docking port 540 to the check valves A and B of the pneumatic cylinder 450 is as follows. That is, as shown in Figure 6, the check valve (A, B) of the pneumatic cylinder 450, the adapter (a, b) is installed so that the air nozzles (530, 530 ') of the docking port 540 check valve It allows easy insertion into (A, B). Meanwhile, the air nozzles 530 and 530 'are deeply inserted into the check valves A and B to allow the air to be supplied into the pneumatic cylinder 450 and discharged from the pneumatic cylinder. In other words, the air nozzles 530, 530 ′ are inserted into the check valves A and B so that the air backflow prevention device 610 in the check valves A and B pushes the air into the air nozzles 530, 530 ′ and Through check valves (A, B) it is free to enter or exit the pneumatic cylinder (450).

Now, when the cooling apparatus 400 according to the present invention intends to fix the die cast casting, the docking port 540 is approached by the pneumatic cylinder 450 so that the upper and lower air nozzles 530 and 530 'have upper and lower check valves. Be inserted into (A, B). At this time, the upper and lower check valves are completely opened. The air is supplied into the pneumatic cylinder 450 through the lower nozzle 530 'and the air in the pneumatic cylinder is discharged to the outside through the upper nozzle 530. In this case, the piston 453 in the pneumatic cylinder 450 is moved to the top dead center in the pneumatic cylinder. At this time, the docking port driving cylinder 550 is operated to retract the docking port 540, so that both air nozzles 530, 530 'away from both check valves (A, B). Thus, both check valves (A, B) are closed so that air is no longer allowed to enter or exit the pneumatic cylinder (450), and the piston (453) is fixed in a state where the top dead center is reached. On the other hand, the piston rod 455 connected to the piston 453 protrudes from the pneumatic cylinder so that the cooling device 400 of the present invention as shown in Figure 3b to fix the die cast casting. As such, the die cast casting fixed to the cooling apparatus needs to be released from the cooling apparatus 400 again after cooling while moving in the horizontal or vertical direction. The method for this is as follows.

When the die-cast casting fixed to the cooling apparatus 400 of the present invention is completed, the docking port 540 approaches the pneumatic cylinder 450 so that both air nozzles 530 and 530 'move up and down check valves A, Inserted into B). When the nozzle is inserted into the check valve, the check valve opens to allow air to flow freely into the pneumatic cylinder through the check valve. At this time, the air flows into the upper check valve (A) through the upper air nozzle 530, and then flows into the pneumatic cylinder, and the air existing in the pneumatic cylinder is lower check valve (B) and lower air nozzle (530 '). When it flows out through the piston, the piston 453 is moved to the bottom dead center in the pneumatic cylinder. At this time, the docking port driving cylinder 550 is operated to retract the docking port from the pneumatic cylinder 450 so that both nozzles 530 and 530 'are separated from both check valves A and B. In this way, the check valves A and B are closed so that the pneumatic cylinder 450 maintains its present state, that is, a state where the piston is lowered to the bottom dead center of the pneumatic cylinder. Since the piston is lowered to the bottom dead center in the cylinder, the piston rod 455 is in a contracted state, causing the cooling device 400 to release the die cast casting 100. In this manner, the die cast casting 100 in which the cooling is completed is moved to the next step by using a robot arm or the like.

In the embodiment of the present invention, it is possible for air to be introduced into the cylinder through each check valve and air is discharged from the cylinder by the air nozzle. However, when the air nozzle is not used, only air can be introduced into each check valve, so a special check valve must be used. That is, since the check valve has a separate air outlet, when the air is introduced through the check valve, a separate air outlet is not used, and when the air is discharged through the check valve, the separate air outlet is used.

On the other hand, the docking port 540 to match the air source 510 to the pneumatic cylinder 450 in order to accurately supply air to the pneumatic cylinder 450 moving in the vertical direction and to accurately discharge the air from the pneumatic cylinder 450 Will be needed. As described above, the docking port 540 is provided with a docking port drive cylinder 550 at the front end, and is moved in the left and right directions as shown in FIG. 5 by the operation of the docking port drive cylinder 550.

When the docking port driving cylinder 550 and the docking port 540 are installed, the pneumatic cylinder 450 moves and stops in consideration of the position where the docking port driving cylinder 550 and the docking port 540 are installed. That is, the docking port driving cylinder 550 is fixedly installed at a predetermined position, and the docking port 540 is connected to the docking port driving cylinder 550 by a piston rod to move a predetermined path. On the other hand, the cooling device 400 is moved in the vertical direction in this embodiment, it is temporarily stopped at a position that can be matched with the docking port 540 while moving in this way to fix the die cast casting 100 or already The fixed die cast casting 100 is released. As such, in the process of fixing and releasing the die cast casting 100, the docking port 540 approaches the pneumatic cylinder 450 to supply and discharge air to the pneumatic cylinder 450, thereby driving the piston and the piston rod. The die cast casting 100 is to be fixed or released from the cooling device 400.

To this end, as shown in Figure 5, the docking port 540 and the pneumatic cylinder 450 is provided with a V block 560 for fixing the position. In the present embodiment, the V-block grooves are formed on both sides of the lower part of the pneumatic cylinder 450, and the V-blocks are provided in the docking port 540 and the like. When the docking port 540 approaches the pneumatic cylinder 450, the V-block ( The combination of 560 allows the air nozzles 530, 530 ′ to be correctly inserted into the check valves A and B of the pneumatic cylinder 450.

In the present invention, when the cooling device 400 moving vertically reaches a predetermined position, the sensor 570 detects and stops it. At this time, the position at which the cooling device 400 stops is 2 mm to 3 mm at a preset position. Will fall within the margin of error. V-block 560 attached to docking port 540 and pneumatic cylinder 450 compensates for this error.
