[0001] SKIRT APPARATUS FOR PREVENTING DOUBLE INJECTION [0002]

The present invention relates to a double injection preventing skirt device, and more particularly, to a dual injection preventing skirt device for preventing molten metal supplied from a pouring device from being injected into a mold other than a desired mold.

Generally, a casting product is made by dissolving steel or the like, injecting the molten metal thus produced into a mold, and then cooling and post-treating the molten metal. Such a process may be performed manually by a worker in the case of a small amount of product, but in the case of a mass produced product, the product is usually produced by an automated die casting facility so as to produce a large number of pieces in a short time.

In this automated mold casting facility, the process of pouring the molten metal into the mold can be accomplished by various methods. Among them, a method of moving the mold using the driving force of a motor and injecting the molten metal into the molten metal inlet port provided in the mold It is mainly used. So that a plurality of molds can be sequentially moved, thereby reducing the work force of the worker.

However, in this mold casting facility, since the molds are continuously connected, in order to accurately inject the molten metal into the desired molten metal injection port, the molten metal injection port must be accurately moved to the molten metal position and the opening and closing of the molten metal must be performed at the correct timing. However, in spite of studies to control and control it, the molten metal is often not injected into the injection port of the desired mold frequently.

When the molten metal can not be accurately injected into the molten metal injection port for the reason described above, double injection phenomenon occurs. The molten metal flows to the periphery of the molten metal inlet port, and the molten metal flows into the other molten metal inlet port other than the desired molten metal inlet port, whereby the molten metal is injected into a single molten metal inlet port. Such double injection phenomenon may significantly degrade the quality of the products produced thereby, and it is necessary to prevent such problems that cause serious problems in productivity.

First, the body part 200 serves as a rotation center for rotating the blocking member 100 connected to the body part 200. The body part 200 may be disposed above the mold 3 at a predetermined interval.

Particularly, the body part 200 may be rotatably connected to a body supporting bar 10 installed on the main water bath supporting bar 2, as shown in the figure. For this purpose, the body part 200 is provided with a body pin 201, The rotation bosses 200b can be formed.

At this time, the body supporting bar 10 is for supporting the body part 200 and has a rod shape, one end part is connected to the upper water main supporting bar 2 and the other end part is connected to the body part 200, .

The body pin 201 rotatably connects the body support bar 10 and the body part 200 and may have a taper pin shape. This allows the body part 200 to rotate in only one direction.

Further, the body pin 201 may be formed by bending the body support bar 10. The other end of the body support bar 10 is bent and inserted into the rotation boss 200b formed in the body 200 as shown in FIG.

The body part 200 may be supported by a support member (not shown) provided on the ground instead of being installed on the main body supporting bar 2 by the body supporting bar 10. The manner and location of the body part 200 vary depending on the design of the designer, and it will be obvious that the size and shape of the mold 3, the position of the water heater 1, and the like can be changed.

The blocking member 100 may be installed on the body 200 and may block the movement of the molten metal flowing from the municipal water tank 1 when the mover 3 is in contact with the molten metal. That is, when the body part 200 is sufficiently rotated to one side about the body pin 201, that is, when the blocking member 100 is in contact with the mold 3, the movement of the molten metal flowing from the water- And the blocking member 100 is spaced apart from the mold 3 by a predetermined distance in a state where the body 200 is rotated to the other side.

The blocking member 100 may be installed on the body 200 at a predetermined distance from the body 200. The shape of the pouring vessel (1) and the surrounding temperature are considered. That is, since the molten metal is generally made at a very high temperature and the pouring machine 1 containing the molten metal is also at a high temperature, the blocking member 100 is spaced apart from the body 200 by a predetermined distance, So that the body part 200 and the power supply 300 are located at a predetermined distance. The detailed structure of the blocking member 100 will be described later with reference to Figs.

Next, the power transmitting unit 400 transmits the power provided from the power providing unit 300, which will be described later, to the body unit 200. The power transmission unit 400 may include a first connection member 401 and a second connection member 402.

The first linking member 401 allows the power of the power distributing unit 300 to be described later to act as a rotational force for rotating the body unit 200. The first linking member 401 is connected to the power providing unit 300 at one end, And may be connected to the second connecting member 402.

The second linking member 402 rotates the body 200 together with the first linking member 401 by the power transmitted from the power distributing unit 300.

At this time, a sliding member 200a is formed at a connecting portion of the body portion 200 connected to the second connecting member 402 so that the second connecting member 402 can move only in the longitudinal direction to the body portion 200 Lt; / RTI > To transmit the power transmitted from the first connecting member 401, which moves up and down, to the body portion 200.

The power transmitting portion 400, that is, the first connecting member 401 and the second connecting member 402 allow the power supply 300 to be installed at a distance away from the main water heater 1. So that the power supply 300 is installed at a distance sufficiently away from the pouring tank 1 at a very high temperature. This ensures that the power supply 300 is smoothly operated with high durability.

In addition, the power transmitting portion 400 described above is only one embodiment for transmitting power from the power providing portion 300, and the first connecting member 401 and the second connecting member as well as the third, (Not shown) may be further added.

Next, the power supplier 300 serves to provide the power to move the first connecting member 401 up and down, and the power may be supplied by the hydraulic method. And may be fixedly installed on the barrel support bar 2 as shown in FIG.

Hereinafter, a method of operating the double injection preventing skirt device according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

Referring to FIGS. 1 and 2, the power providing unit 300 provides power for moving the first connecting member 401 in the up and down direction. The second connecting member 402 connected thereto is sequentially moved by the first connecting member 401 moving to one side. Then, the body portion 200 connected to the second connecting member 402 and the blocking member 100 are rotated together.

As a result, when the first connecting member 401 moves upward, the blocking member 100 is brought into contact with the mold 3, and the flow of the molten metal is blocked at this time. Conversely, when the first connecting member 401 moves downward, the blocking member 100 is spaced apart from the mold 3 by a predetermined distance.

1, when the body 200 is fully rotated to one side, that is, in a state in which the blocking member 100 is in contact with the mold 3, the molten metal And the blocking member 100 is spaced apart from the mold 3 by a predetermined distance when the body 200 is rotated to the other side. This prevents the molten metal from flowing into the other molten metal inlet 4 'without flowing into the desired molten metal inlet 4.
