진동을 이용한 금형 주조방법{METHOD FOR METALLIC PATTERN CASTING USING OSCILLATION}Mold casting method using vibration {METHOD FOR METALLIC PATTERN CASTING USING OSCILLATION}

본 발명은 진동을 인가할 수 있도록 된 진동 주조장치에 관한 것으로, 특히 인가된 진동에 의해 금형 벽면과 금형 중앙부의 용탕의 응고속도 편차를 감소시킴에 따라, 주조체에서 발생하는 수축공의 깊이를 최소화하도록 된 진동 주조장치에 관한 것이다.
The present invention relates to a vibrating casting apparatus which is capable of applying vibration, and in particular, as the variation in the solidification speed of the molten metal in the mold wall and the mold center is reduced by the applied vibration, the depth of the shrinkage hole generated in the cast body is reduced. A vibrating casting device adapted to be minimized.

기존의 주조장치의 주형틀 내부에 있어서는, 공기 및 가스는 주조장치의 분할면, 압탕 및 배출구를 통하여 배출제거되도록 하고 있으나, 완전히 제거되지 않아 가스와 수분이 용탕에 혼입되는 것을 막지 못하게 되어 생산된 주물에 기포 등이 발생하게 되었다. In the casting mold of the existing casting apparatus, air and gas are discharged and removed through the dividing surface of the casting apparatus, pressurization and outlet, but are not completely removed to prevent gas and moisture from entering the molten metal. Bubbles were generated in the casting.

이에 따라, 가스와 수분이 용탕에 혼입됨에 따라 주요부위에 발생하는 기포로 인해 얇은 부분일수록 불완전하게 채워지는 미성형 등의 문제점이 발생하게 되었다. Accordingly, as the gas and moisture are mixed in the molten metal, problems such as incomplete molding, which are incompletely filled, occur due to bubbles generated in the main part.

또한, 주조장치는 금형 벽면 및 금형 중앙부에 따라 그 응고속도 편차가 나타남에 따라, 주조체의 중앙에는 수축공이 형성되고, 이 수축공에 대해서 주조장치의 압탕(riser, head)로부터 추가의 용탕이 공급되도록 하고 있다. In addition, as the casting apparatus exhibits a variation in the solidification speed depending on the mold wall and the mold central portion, shrinkage holes are formed in the center of the casting body, and additional molten metal is removed from the riser head of the casting apparatus. To be supplied.

하지만, 이를 위해서는 별도의 압탕 및 수축공을 충전시킬 추가의 용탕을 구비해야 하는 문제점이 있었다.
However, for this purpose, there was a problem in that additional molten metal and additional molten metal to fill the shrinkage holes were provided.

이에 본 발명은 상기와 같은 사정을 감안하여 이루어진 것으로, 용탕 내부에 진공을 인가할 수 있는 진동 인가장치가 구비됨에 따라, 인가된 진동에 의해 금형 벽면과 금형 중앙부의 용탕의 응고속도 편차를 감소시키도록 된 진동 주조장치를 제공하는 것을 목적으로 한다.
Accordingly, the present invention has been made in view of the above circumstances, and according to the vibration application device capable of applying a vacuum to the inside of the molten metal, the variation in the solidification speed of the molten metal in the mold wall and the mold center is reduced by the applied vibration. It is an object of the present invention to provide a vibrating casting apparatus.

이하, 첨부한 도면을 참고로 하여 본 발명의 실시예에 대하여 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자가 용이하게 실시할 수 있도록 상세히 설명한다. 그러나 본 발명은 여러 가지 상이한 형태로 구현될 수 있으며 여기에서 설명하는 실시예에 한정되지 않는다.
Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

도 1은 본 발명에 따른 진동 주조장치(100)의 개략적인 구성을 나타낸 측단면도이다.1 is a side cross-sectional view showing a schematic configuration of a vibration casting device 100 according to the present invention.

본 발명에 따른 진동 주조장치(100)는, 용탕을 수용하는 금형(10)과, 추가의 용탕을 상기 금형에 제공하는 압탕(20)과, 상기 금형(10)에 진동을 인가하는 진동발생장치(30)를 포함하여 구성된다. The vibration casting device 100 according to the present invention includes a mold 10 for accommodating molten metal, a pressure bath 20 for providing additional molten metal to the mold, and a vibration generator for applying vibration to the mold 10. It comprises 30.

또한, 상기 압탕(20) 및 진동발생장치(30)의 동작을 제어하는 제어부(40)를 더 포함하여 구성된다. In addition, the control unit 40 for controlling the operation of the hot water 20 and the vibration generating device 30 is further configured.

여기서, 상기 금형에는 상부의 개구로부터 용탕이 공급되어, 소정 시간 경과된 후 금형(10) 형상에 따라 주조물을 형성하게 된다. 도 1에 있어서는 상기 금형(10)이 대략 사각형상인 것으로 도시하고 있지만, 그 형상은 다양하게 형성될 수 있다. Here, the molten metal is supplied from the opening of the upper portion to form a casting according to the shape of the mold 10 after a predetermined time elapses. In FIG. 1, the mold 10 is illustrated as being substantially rectangular in shape, but may be formed in various shapes.

또한, 상기 금형 내에 용탕 F이 공급됨에 따라, 금형 표면으로부터 이격된 중앙부에 수축공이 형성되는 상태가 도시된다. 이러한 수축공 F1의 높이(또는 깊이)는, 금형 벽면과 금형 중앙부의 용탕의 응고속도 편차가 클수록 커지고, 작을 수록 작아진다. 즉, 수축공 F1의 높이(또는 깊이)는, 금형 벽면과 금형 중앙부의 용탕의 응고속도 편차에 비례한다. In addition, as the molten metal F is supplied into the mold, a state in which shrinkage holes are formed in a central portion spaced from the mold surface is illustrated. The height (or depth) of such shrinkage hole F1 is larger as the solidification speed deviation between the mold wall surface and the molten metal in the mold center part increases, and the smaller it becomes smaller. That is, the height (or depth) of the shrinkage hole F1 is proportional to the variation in the solidification speed between the mold wall surface and the molten metal in the mold center portion.

따라서, 상기 제어부(40)는 상기 금형(10)에 용탕이 공급되면, 상기 진동발생장치(30)를 동작시켜서, 금형(10)에 진동이 인가되도록 한다. 또한, 용탕의 응고되어 수축공 F1이 형성됨에 따라, 압탕(20)을 통해 수축공에 추가의 용탕이 주입되도록 한다. Therefore, when the molten metal is supplied to the mold 10, the controller 40 operates the vibration generator 30 to apply vibration to the mold 10. In addition, as the shrinkage hole F1 is formed by solidification of the molten metal, additional molten metal is injected into the shrinkage hole through the pressure bath 20.

한편, 바람직하게는, 상기 진동발생장치(30)는, 상기 금형에서, 상기 압탕과 인접한 부분에 구비된다. 이에 따라, 용탕 표면에 진동을 인가할 수 있게 되므로, 용탕 표면에서 발생되는 수축공의 형성을 가능한 방지할 수 있게 된다.
On the other hand, Preferably, the vibration generating device 30 is provided in a portion adjacent to the hot water in the mold. Accordingly, since the vibration can be applied to the molten surface, it is possible to prevent the formation of shrinkage holes generated in the molten surface.

본 발명에 따른 본 발명에 따른 진동 주조장치(100)에 있어서는, 상기 금형 벽면과 금형 중앙부의 용탕의 응고속도 편차 및 수축공 F1의 높이(또는 깊이)를 감지할 수 있는 온도 감지 및 연산 수단 및/또는 촬상수단을 더 포함하여 구성될 수 있다.
In the vibration casting device 100 according to the present invention, the temperature sensing and calculating means for detecting the variation in the solidification speed of the molten metal in the mold wall and the mold center and the height (or depth) of the shrinkage hole F1; And / or further comprising an imaging means.

한편, 도 2는 본 발명에 따른 효과를 나타낸 그래프로서, 본 발명에 따른 진동 주조장치(100)에 있어서의 금형 내에서의 온도 표준편차가 종래보다 작은 상태를 나타낸다.
On the other hand, Figure 2 is a graph showing the effect according to the present invention, the temperature standard deviation in the mold in the vibration casting device 100 according to the present invention is smaller than the conventional state.
