본 발명은 다이캐스팅용 용탕컵의 산화물 차단 장치에 관한 것으로서, 보다 상세하게는 알루미늄 용탕을 다이캐스팅 장치의 스핀들에 투입할 때, 용탕의 표면에 형성되는 산화물층이 스핀들에 함께 투입되어 다이캐스팅 불량을 발생시키는 것을 개선한 다이캐스팅용 용탕컵의 산화물 차단 장치에 관한 것이다.The present invention relates to an oxide blocking device of a die-casting molten cup, and more particularly, when an aluminum molten metal is added to a spindle of a die-casting apparatus, an oxide layer formed on the surface of the molten metal is added to the spindle to generate die casting defects. The present invention relates to an oxide barrier device for a molten cup for die casting.

일반적으로, 표면 정밀도가 우수한 주물을 단시간에 생산하기 위해서는 다이캐스팅(Die-Casting) 장치를 사용하여 금형등을 제작하게 된다.In general, in order to produce castings having excellent surface precision in a short time, dies and the like are manufactured using a die-casting apparatus.

상기한 다이캐스팅 장치는 알루미늄 잉곳등과 같은 재료를 버너에서 용해함과 아울러 용해된 용탕을 다이캐스팅 장치의 슬리브에 투입하여 금형에 가압 주입하게 된다.The die casting apparatus dissolves a material such as an aluminum ingot in a burner and injects the molten molten metal into a sleeve of the die casting apparatus to pressurize the mold.

슬리브에서 용탕이 가압 주입되면 용탕이 응고된 후, 금형을 분리하여 제품을 취출함과 아울러 사출된 제품의 탕구제거, 버링가공, 숏블라스트 가공등을 통해 완제품으로 가공하게 된다.When the molten metal is pressurized in the sleeve, the molten metal is solidified, the mold is separated and the product is taken out, and the molten metal is processed into a finished product by removing the molten metal, removing burring, and shot blasting.

물론, 다이캐스팅 금형은 다음 공정을 위해 냉각됨과 아울러 이형제가 도포되게 된다.Of course, the die casting mold is cooled for the next process and the release agent is applied.

상기한 슬리브에 용탕을 주입하기 위해서는 별도의 자동 용탕 주입 장치가 사용되는 바, 상기한 용탕 주입 장치는 용탕컵이 장착된 로봇으로서, 도3에 도시된 바와 같이 용탕(M)이 충진된 저장용기(50)에서 용탕(M)을 일정량씩 떠낼 수 있게 용탕컵(51)이 장착되어 있고, 상기한 용탕컵(51)의 후면에 형성된 주입구(52)로 슬리브(S)에 용탕(M)을 연속 주입하여 금형(D)으로 공급하도록 구성된다.In order to inject molten metal into the sleeve, a separate automatic molten metal injection device is used. The molten metal injection device is a robot equipped with a molten metal cup, and a storage container filled with molten metal (M) as shown in FIG. 3. The molten metal cup 51 is mounted so that the molten metal M may be removed from the molten metal M by a predetermined amount, and the molten metal M is disposed on the sleeve S by the inlet 52 formed at the rear surface of the molten metal cup 51. It is configured to continuously feed and feed into the mold (D).

여기서, 상기한 저장용기(50)에 충진된 용탕(M)의 윗면은 공기에 노출되기 때문에 급속하게 산화물층(O)이 형성되게 된다.Here, since the upper surface of the molten metal M filled in the storage container 50 is exposed to air, the oxide layer O is rapidly formed.

그러나, 상기한 바와 같이 자동 용탕 주입 장치를 사용하여 다이캐스팅 장치의 슬리브에 용탕을 공급하게 되면, 상기한 용탕의 윗면에 형성되는 산화물층을 용탕컵이 함께 떠서 슬리브에 공급하기 때문에, 슬리브에서 다이캐스팅 금형으로 사출 성형할 때 성형되는 제품에 불량이 발생되는 문제점이 있다.However, when the molten metal is supplied to the sleeve of the die casting apparatus using the automatic molten metal injection apparatus as described above, the die layer is cast from the sleeve because the molten cup floats together and supplies the sleeve to the sleeve. There is a problem that a defect occurs in the product to be molded when injection molding.

즉, 산화된 상태인 용탕을 슬리브를 통해 금형에 주입하는 것이 되기 때문에, 상기한 산화된 용탕(산화물층)이 위치된 부분의 제품에서 불량이 발생되는 것이다.That is, since the molten metal in the oxidized state is injected into the mold through the sleeve, a defect occurs in the product of the portion where the oxidized molten metal (oxide layer) is located.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 상기한 용탕컵으로 용탕을 떠서 슬리브에 주입할 때 산화물층은 용탕컵에 들어가지 않도록 함으로써, 다이캐스팅 금형으로 성형할 때의 제품 불량을 방지할 수 있는 다이캐스팅용 용탕컵의 산화물 차단 장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and when the molten metal is poured into the sleeve by pouring the molten metal into the sleeve, the oxide layer does not enter the molten cup, thereby preventing product defects when molding into a die casting mold. It is to provide an oxide blocking device of the molten cup for die casting that can be prevented.

상기한 목적을 실현하기 위하여 본 발명은 용탕컵의 외주면 선단이 고정되고 아울러 종단이 서로 일정폭이상 겹치도록 링형상으로 형성된 상태에서 용탕컵의 외주면에 밀착되어 용탕컵의 상부보다 높게 위치되는 제1, 2커버링과; 상기한 제1, 2커버링의 겹친 부분을 밀어서 용탕컵과 이격시켜 용탕이 용탕컵으로 유입되도록 함과 아울러 제1, 2커버링이 용탕컵과 밀착되어 용탕의 유입이 차단되도록 하는 작동 수단;으로 구성됨을 특징으로 하는 다이캐스팅용 용탕컵의 산화물 차단 장치를 제공한다.In order to achieve the above object, the present invention includes a first end of which the outer circumferential surface of the molten cup is fixed, and the ends are in contact with the outer circumferential surface of the molten cup in a state of being formed in a ring shape so that the ends overlap with each other by a predetermined width or more, and positioned higher than the upper portion of the molten cup. 2 coverings; An operation means for pushing the overlapped portions of the first and second coverings so as to be spaced apart from the molten cups so that the molten metals are introduced into the molten cups, and the first and second coverings are in close contact with the molten cups to block the inflow of the molten metals. It provides an oxide blocking device of the molten cup for die casting.

도1은 본 발명에 따른 다이캐스팅용 용탕컵의 산화물 차단 장치를 도시한 사시도로서, 용탕컵(51)의 외주면 선단이 용접 등으로 고정됨과 아울러 종단이 서로 일정폭이상 겹치도록 링형상으로 형성된 상태에서 용탕컵(51)의 외주면에 밀착되어 용탕컵(51)의 상부보다 높게 위치되는 제1, 2커버링(1, 2)과, 상기한 제1, 2커버링(1, 2)의 겹친 부분을 밀어서 용탕컵(51)과 이격시키거나 당겨서 용탕컵(51)과 밀착시키도록 하는 작동 수단으로 이루어져 있다.1 is a perspective view showing an oxide blocking device of the die-casting molten cup according to the present invention, in which the outer peripheral surface of the molten cup 51 is fixed by welding or the like, and the ends are formed in a ring shape so that the ends overlap a predetermined width or more with each other. The first and second coverings 1 and 2 which are in close contact with the outer circumferential surface of the molten cup 51 and positioned higher than the upper portion of the molten cup 51 and the overlapping portions of the first and second coverings 1 and 2 described above are pushed It is composed of the operating means to be in close contact with the molten cup 51 by pulling or pulling away from the molten cup (51).

즉, 상기한 작동 수단이 제1, 2커버링(1, 2)의 겹친 부분을 밀게 되면 용탕컵(51)과 이격되면서 용탕(M)이 용탕컵(51)으로 흘러 들어오게 되고, 제1, 2커버링(1, 2)이 용탕컵(51)에 밀착되면 용탕(M)보다 제1, 2커버링(1, 2)이 높기 때문에 용탕(M)이 용탕컵(51)으로 흘러들어오지 못하도록 하는 것이다.That is, when the operating means pushes the overlapping portions of the first and second coverings 1 and 2, the molten metal M flows into the molten metal cup 51 while being spaced apart from the molten metal cup 51. When the two coverings 1 and 2 are in close contact with the molten metal cup 51, the first and second coverings 1 and 2 are higher than the molten metal M so that the molten metal M does not flow into the molten metal cup 51. .

상기한 제1, 2커버링(1, 2)이 용탕컵(51)에 밀착되면 용탕컵(51)을 용탕(M)에 함침시켜도 제1, 2커버링(1, 2)에 의해 용탕(M)이 흘러들어오지 못하게 되고, 작동 수단이 제1, 2커버링(1, 2)을 밀어서 용탕컵(51)과 이격시키게 되면 산화물층(O)은 제1, 2커버링(1, 2)에 의해 차단된 상태에서, 산화물층(O) 아래 부분의 용탕(M)만이 용탕컵(51)으로 들어오도록 하는 것이다.When the first and second coverings 1 and 2 are in close contact with the molten metal cup 51, the molten metal M may be melted by the first and second coverings 1 and 2 even if the molten metal cup 51 is impregnated with the molten metal M. The oxide layer O is blocked by the first and second coverings 1 and 2 when the operating means pushes the first and second coverings 1 and 2 so as to be spaced apart from the molten cup 51. In the state, only the molten metal M below the oxide layer O is allowed to enter the molten metal cup 51.

상기한 작동 수단은 상기한 제1, 2커버링(1, 2)의 겹친 부분에서 내측에 위치되는 커버링에 로드(3)가 연결되고 용탕컵(51)에서 주입구(52)의 상부에 고정 설치되는 실린더(4)로 구성되어 있다.The operating means is connected to the rod (3) is located on the inner side in the overlapping portion of the first and second coverings (1, 2) is fixed to the upper portion of the inlet (52) in the molten cup 51 It consists of the cylinder 4.

즉, 상기한 실린더 로드(3)가 제1, 2커버링(1, 2)의 겹친 부분을 밀면 제1, 2커버링(1, 2)이 탄성에 의해 벌어지면서 용탕컵(51)과 이격되고, 실린더 로드(3)가 후진하면 자체 탄성에 의해 복귀되어 용탕컵(51)과 밀착되도록 하는 것이다.That is, when the cylinder rod 3 pushes the overlapping portions of the first and second coverings 1 and 2, the first and second coverings 1 and 2 are separated by the elasticity and spaced apart from the molten metal cup 51. When the cylinder rod 3 is retracted, the cylinder rod 3 is returned by its elasticity to be in close contact with the molten metal cup 51.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 저장 용기(50)에서 용탕(M)을 떠내기 위해, 자동 용탕 주입 장치의 용탕컵(51)을 용탕(M)으로 넣게 되는 바, 도2a에 도시된 바와 같이 제1, 2커버링(1, 2)이 탄성에 의해 강하게 용탕컵(51)에 밀착된 상태에서 용탕컵(51)은 산화물층(O)의 아래에 위치되도록 하고, 제1, 2커버링(1, 2)으로는 용탕(M)이 흘러들어오지 못할 정도로 잠기도록 한다.Referring to the operation and effect of the present invention as described above, in order to remove the molten metal (M) from the storage container 50, the molten metal cup 51 of the automatic molten metal injection device is put into the molten metal (M), as shown in Figure 2a As shown in the drawing, the first and second coverings 1 and 2 are strongly adhered to the molten cup 51 by elasticity so that the molten cup 51 is positioned under the oxide layer O. 2 Covering (1, 2) to be locked so that the molten metal (M) does not flow.

이 상태에서는 산화물층(O)이 제1, 2커버링(1, 2)에 차단되어 용탕컵(51)으로 들어가지 못하는 바, 상기한 실린더(4)를 작동시키게 되면 도2b에 도시된 바와 같이 제1, 2커버링(1, 2)이 벌어지면서 용탕컵(51)과의 사이 간격으로 용탕(M)이 흘러들어오게 된다.In this state, the oxide layer O is blocked by the first and second coverings 1 and 2 and thus cannot enter the molten metal cup 51. When the cylinder 4 is operated, as shown in FIG. 2B. As the first and second coverings 1 and 2 are opened, the molten metal M flows in at an interval between the molten cups 51.

즉, 산화물층(O)의 아래 부분(산화되지 않은 용탕) 용탕(M)만이 용탕컵(51)으로 흘러들어오게 되는 것으로서, 용탕(M)이 용탕컵(51)에 충진되면 다시 실린더(4)를 복귀시켜 제1, 2커버링(1, 2)이 용탕컵(51)에 밀착되도록 한다.That is, only the lower portion (not oxidized) molten metal M of the oxide layer O flows into the molten metal cup 51. When the molten metal M is filled in the molten metal cup 51, the cylinder 4 ), The first and second coverings 1 and 2 are brought into close contact with the molten metal cup 51.

이 상태에서 자동 주입 장치가 용탕컵(51)을 슬리브(S)로 이송한 후 도2c에 도시된 바와 같이 용탕컵(51)의 후면인 주입구(52)를 기울여 슬리브(S)로 용탕(M)을 주입하게 되는 것이다.In this state, the automatic injection device transfers the molten metal cup 51 to the sleeve S, and inclines the inlet 52, which is the rear surface of the molten metal cup 51, to the molten metal M as the sleeve S as shown in FIG. 2C. ) Will be injected.

상기한 바와 같이 용탕컵(51)으로 용탕(M)의 산화물층(O)이 유입되지 않도록 제1, 2커버링(1, 2)으로 차단하여 용탕(M)을 떠내게 되면 슬리브(S)에 주입되는 용탕(M)에도 산화물층(O)이 섞이지 않게 됨으로써, 다이캐스팅 사출에서의 제품 불량을 대폭 감소시킬 수 있게 되는 것이다.As described above, the first and second coverings 1 and 2 are blocked by the first and second coverings 1 and 2 to prevent the oxide layer O of the molten metal M from flowing into the molten metal cup 51. Since the oxide layer O is not mixed with the molten metal M to be injected, it is possible to greatly reduce product defects in die casting injection.

이상과 같이 본 발명은 다이캐스팅 사출 성형 장치의 슬리브에 용탕을 공급할 때 저장 용기에 충진된 용탕의 윗면 산화물층이 슬리브로 공급되지 않도록 함으로써, 다이캐스팅시의 산화물층에 의한 제품 불량을 방지할 수 있는 이점이 있다.As described above, the present invention does not supply the upper oxide layer of the melt filled in the storage container to the sleeve when supplying the molten metal to the sleeve of the die casting injection molding apparatus, thereby preventing product defects due to the oxide layer during die casting. There is this.
