The present invention relates to an aluminum casting system, and more particularly to an aluminum casting system that can reduce the installation cost, and improve the production speed by separating the rotary disk and the casting unit of the casting device.

Aluminum is a metal element belonging to group 3B of the periodic table. It is a light and soft metal of silver white color. It is widely distributed so as to make up 8% of the earth's crust and is the second largest deposit after iron.

Aluminum is used not only as a main material for aircraft, ships and vehicles because of its light properties, but also as a transmission line using points that are electricity transfers. In addition, since oxidation does not occur well, food industry, tableware, etc. may be made, and also used for paint, building materials, and raw materials. In particular, since it can be made very thin due to its elongated property (ductility), it is widely used for making kitchen foils, printing plates, high-quality packaging paper, communication equipment, semiconductors, electronics, electronic parts, and leisure products.

The aluminum product is manufactured by a casting method in which a solution in which aluminum metal is dissolved is injected into a mold to be solidified, and then separated from the mold. The aluminum manufacturing system will be described with reference to FIGS. 1 and 2.

1 is a plan view of a conventional aluminum casting system and FIG. 2 is a front view of a conventional aluminum casting system.

As shown in FIGS. 1 and 2, the conventional aluminum casting system 1 includes an aluminum solution input device 10, an aluminum casting transfer device 20, and an aluminum casting device 30.

In the above-described configuration, the aluminum casting apparatus 30 includes a casting unit 33 in which a mold is coupled and four casting units 33 are installed on the upper surface at an angle of 90 degrees, and rotate and stop every 90 degrees. 31).

Accordingly, the conventional aluminum casting system 1 drives the rotating plate 31 of the aluminum casting device 30 to rotate a predetermined angle, that is, 90 degrees, and then stops the rotating plate 31. ) And the aluminum casting transport apparatus 20 are driven to inject the aluminum solution, and the solidified casting is taken out.

Since the turntable 31 is rotated 90 degrees again, by repeating this process it is possible to produce a large amount of aluminum products.

Meanwhile, the aluminum casting apparatus 30 of the conventional aluminum casting system 1 has many problems as the casting unit 33 is installed on the rotary plate 31. First, the casting is installed on the rotary plate 31. There is a problem in that the number of units 33 is limited.

That is, due to the size of the casting unit 33, as shown in Figure 1 is generally limited to four casting units 33 installed on the rotary plate (31).

Therefore, as the number of casting units 33 installed on the rotating plate 31 is limited, there is a problem that the production speed of the aluminum product is lowered.

In particular, in order to increase the number of the casting unit 33 installed on the turntable 31, the size of the turntable 31 is increased, but increasing the size of the turntable 31 requires a lot of installation space. According to the increase in the size of the rotary disk 31 and the number of casting units 33, there is a problem in that the installation cost and maintenance cost is increased because a large capacity motor capable of generating a large rotational force.

The present invention has been made in order to solve the above problems, to separate the turntable and the casting unit, to produce the casting unit and the mold in a separate type, to reduce the installation cost and increase the production amount by placing only two casting units The object is to provide an aluminum casting system.

In order to achieve the above object, an aluminum casting system includes an aluminum casting system comprising an aluminum solution input device, an aluminum casting feeder, and an aluminum casting device, the aluminum casting device comprising: a mold frame in which a mold is coupled; A rotating plate made of a disc on which the mold frame is disposed at regular intervals and a motor for rotating and stopping the disc at regular intervals; It is fixedly installed between the rotary plate and the aluminum solution input device, and when the rotary plate is paused, one mold frame combined with a mold that is not injected with aluminum solution of the mold frame is the aluminum solution input device. An injection casting unit for moving the in-situ on the disc when the aluminum solution is injected into the mold; And a fixed mold installed between the rotary disk and the aluminum casting feeder, and when the rotary disk is paused, the mold of the aluminum mold injected into the mold is combined with a filling mold solidified into a casting. And a take-out casting unit which moves to a place on the disc again when the casting in the filling mold is taken out after moving to a transfer device.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the aluminum casting system of the present invention.

3 is a plan view of an aluminum casting system according to the present invention, and FIG. 4 is a front view of an aluminum casting system according to the present invention.

At this time, the turntable 100 may be achieved by the same turntable as the conventional turntable 31, and the mold 110 is rotated at a predetermined interval between the disc 110 and the disc 110 at regular intervals. A motor 130 is made to pause.

That is, if using the same size of the disc 110 as the prior art, since only the mold frame 300 smaller and lighter than the casting unit 500 is located on the disc 110 of the mold 200 located on the disc 110 The number can be increased, and the capacity of the motor 130 for rotating the disc 110 can be reduced.

At this time, rotation at regular intervals is achieved by controlling the microcomputer that operates the motor 130 in advance according to the number of molds 300 positioned on the disc 110.

Next, the injection casting unit 500 is installed between the turntable 100 and the aluminum solution input device 10, and when the turntable 100 is paused, the ball in which the aluminum solution is not injected in the mold 300 is injected. One mold frame 300 coupled to the mold is moved to the aluminum solution injector 10, and when the aluminum solution is injected into the mold, the mold 300 is moved into place on the disc 110.

Next, the blow-out casting unit 500 'is installed between the turntable 100 and the aluminum casting transport apparatus 20. When the turntable 100 is temporarily stopped, the aluminum solution injected into the mold 300 is hardened. After moving the mold 300 coupled to the mold solidified with the casting to the aluminum casting feeder 20, when the casting in the filling mold is taken out, it is moved back into place on the disc 110.

Therefore, since the casting units 500 and 500 'are spaced apart from the outer side of the turntable, the number of installations of the casting units 500 and 500' can be reduced, thereby reducing the installation cost. Since the size can be reduced, the installation space can be reduced, and the number of molds 200 that can be placed on the turntable 100 can be increased, thereby increasing the production speed.
