Description
제 1 도는 본 고안의 전체도.1 is an overall view of the present invention.
제 2 도는 제 1 도의 점선내 확대 단면도.2 is an enlarged cross-sectional view in FIG. 1 of FIG.
제 3 도는 본 고안의 확대 단면도.3 is an enlarged cross-sectional view of the present invention.
본 고안은 코아금형에 코아용 모래를 투입하는 주물용 코아제조기의 토출구에 관한 것이다.The present invention relates to the discharge port of the casting machine for casting the core to put the core sand in the core mold.
종래의 코아 제조기의 토출구는 금형에 모래를 투입하고 스톱퍼로 통로를 막아 모래의 토출은 막았으나, 스톱퍼와 통로사이가 정확하게 밀접되지 못하므로 모래가 조금씩 흘러 내리는 경향이 있어 금형을 설치하기 곤란한 예가 많았다.In the discharge port of the conventional core maker, sand was injected into the mold and the passage was blocked with a stopper to prevent the discharge of sand. .
본 고안은 이러한 점을 감안하여 고안한 것으로 토출구의 내부에서 외부로 하향 경사지게 수개의 통공을 뚫어 주므로서 압축공기에 의하여 토출관을 따라 내려온 모래는 토출구의 외부에서 외향 경사지게 뚫린 통공을 따라 외부로 배출되어 금형속으로 투입되는 것이며, 모래의 투입이 끝나면 압축 공기의 송입을 중단하여 주므로 모래는 더이상 배출되지 않는 것으로 모래의 배출을 막아주는 작업이 아주 간단하게 이루어져 금형의 설치작업이 용이하도록 한 것으로 이를 첨부된 도면에 의하여 구조를 상세히 설명하면 다음과 같다.The present invention has been devised in view of this point, and the sand down the discharge pipe by the compressed air is discharged to the outside along the through hole which is inclined outward from the outside of the discharge hole by drilling a plurality of through holes inclined downward from the inside of the discharge hole to the outside. When the sand is finished, the compressed air is stopped and the sand is not discharged anymore, so the work of preventing the sand is very simple, making it easy to install the mold. Referring to the structure in detail by the accompanying drawings as follows.
기체(1)의 일측 상부에 모래수장통(2)을 설치하여 모래수장통(2)과 하부에 설치된 이송관(4)으로 연통한 것에 있어서 배출구(5)에서 외향경사지게 하여 P Pa점이 형성되도록 뚫린 돌출구(7)를 토출부(3)내에 삽설되게 한 것이며, 미설명부호 8은 코아금형이고, 9는 압축공기 송입관이며, 10은 모래이다.The sand canister (2) is installed on the upper side of the gas (1), and communicated with the sand canister (2) and the conveying pipe (4) installed in the lower portion so as to be inclined outwardly from the outlet (5) so that the P Pa point is formed. The perforated protrusion 7 is inserted into the discharge portion 3, where reference numeral 8 is a core mold, 9 is a compressed air inlet pipe, and 10 is sand.
이와같이된 본 고안의 작용, 효과를 상세히 설명하면 다음과 같다. 코아용 금형(8)에 모래를 투입코저할때는 압축공기 송입관(9)에 압축공기를 넣어주면 압축공기는 이송관(4)을 따라 밀리면서 토출부(3)에 삽설되어 있는 토출구(7)의 외부에서 경사진 통공(6)을 따라 배출구(5)에서 금형(8)에 모래가 투입되는 것이며, 모래의 투입이 다 끝났을 경우에는 압축공기의 송입을 중단시키면 모래는 더 이상 내려오지 않으며, 토출부(3)와 토출구(5)사이에 남아있던 모래는 통공(6)이 배출구(5)쪽으로는 높고 외부쪽으로 낮아지도록 경사지게 뚫리어져 있기 때문에 즉 P점이 Pa점보다 높게 되어 있어 배출구(5)로 들어가지 않게되는 것으로 금형에 모래를 투입하고 막는 것을 간편하고 용이하게 실시할 수 있고, 모래가 떨어지지 않아 금형의 설치가 용이한 유용한 고안이다.Referring to the operation, effects of the present invention as described in detail as follows. When sand is injected into the core mold 8, the compressed air is inserted into the compressed air inlet pipe 9, and the compressed air is pushed along the transfer pipe 4, and the discharge port 7 inserted in the discharge part 3 is inserted. Sand is introduced into the mold 8 from the outlet 5 along the through hole 6 inclined from the outside. When the sand is finished, the sand does not come down any more when the supply of compressed air is stopped. The sand remaining between the discharge portion 3 and the discharge port 5 is drilled inclined so that the through hole 6 is higher toward the discharge port 5 and lower toward the outside, that is, the P point is higher than the Pa point, so that the discharge port 5 It is not useful to enter and block sand into the mold simply and easily.
