도 2a는 본 발명의 일 실시예에 따른 주조품 탈사장치를 나타내는 도이고, 도 2b는 도 2a의 A-A에서 바라본 평면도이다.FIG. 2A is a view illustrating a cast-away desorption value according to an embodiment of the present invention, and FIG. 2B is a plan view seen from A-A of FIG. 2A.

도 2a, 도 2b에서 도시한 바와 같이, 본 발명에 따른 주조품 탈사장치는 주조품(10)의 하면에서 상기 주조품(10)의 상/하 운동을 지지하고 다수의 홀(25)이 형성된 지지수단과(20), 상기 지지수단(20)의 하부에 이격되어 설치되고, 상기 주조품(10)의 하강 시에 상기 지지수단(20)에 형성된 홀(25)을 관통하여 상기 주조품(10)에 부착된 주물사를 타격하는 타격수단(30)과, 상기 타격수단(30)이 고정되는 플레이트(40)와, 상기 지지수단(20)과 상기 플레이트(40) 사이에 설치되고 상기 지지수단(20)에 탄성력을 전달하는 탄성부재(50)를 포함하여 구성된다.As shown in Figure 2a, Figure 2b, the cast-departing device according to the present invention supports the up / down movement of the casting 10 in the lower surface of the casting 10 and the support means formed with a plurality of holes 25 and 20, spaced apart from the lower portion of the support means 20, and attached to the cast product 10 by penetrating through the hole 25 formed in the support means 20 when the cast product 10 is lowered. A striking means 30 that strikes the molding sand, a plate 40 to which the striking means 30 is fixed, and is installed between the support means 20 and the plate 40 and has an elastic force on the support means 20. It is configured to include an elastic member 50 for transmitting.

상기와 같이 주조품(10)에 부착된 주물사를 별도로 설치된 타격수단(30)에 의해 직접 타격하여 제거할 수 있는 효과가 있다.The casting sand attached to the casting 10 as described above has an effect that can be removed by hitting directly by the blow means 30 separately installed.

상기 타격수단(30)은 상기 지지수단(20)이 하강할 시에는 주조품(10)에 부착된 주물사를 타격하고 상기 지지수단(20)이 상승할 시에는 상기 주조품(10)과 이격되게 설치될 수 있다.The striking means 30 hits the molding sand attached to the casting 10 when the support means 20 is lowered, and is spaced apart from the cast 10 when the support means 20 is raised. Can be.

이와 같이, 상기 타격수단(30)은 상기 주조품(10)에 부착된 주물사를 직접 타격하여 탈사공정이 끝나면 상기 지지수단(20)이 다시 원상복귀 되고, 상기 타격수단(30)이 상기 지지수단(20)의 하부로 사라지게 된다.As such, the striking means 30 directly strikes the foundry sand attached to the casting 10, and when the degassing process is completed, the support means 20 is returned to its original state, and the striking means 30 is the support means ( Disappears to the bottom of 20).

또한, 상기 타격수단(30)은 봉 형상으로 형성되어 상기 주조품(10)에 형성된 주물사를 타격하게 된다.In addition, the striking means 30 is formed in a rod shape to strike the molding sand formed in the casting (10).

상기 탄성부재(50)는 상기 타격수단(30)의 외측에 삽입되어 형성될 수 있다.The elastic member 50 may be inserted into the outer side of the hitting means 30.

바람직하게는 상기 탄성부재(50)는 스프링으로 구성되고 상기 타격수단(30) 의 외측에 삽입되어 형성될 수 있다.Preferably, the elastic member 50 may be formed of a spring and inserted into the outer side of the hitting means 30.

상기와 같이 구성되는 본 발명에 따른 주조품 탈사장치의 작용(동작)을 설명하면 다음과 같다.Referring to the operation (operation) of the cast article desalination apparatus according to the present invention configured as described above are as follows.

도 3a는 본 발명에 따라 탈사공정의 초기상태를 나타내는 도이고, 도 3b는 본 발명에 따라 탈사공정을 나타내는 도이다.Figure 3a is a view showing an initial state of the desalination process according to the present invention, Figure 3b is a view showing a desalination process according to the present invention.

도 3a, 도 3b에서 도시한 바와 같이 주조품(10)이 주조되고, 탈사 공정에 들어오면 상기 주조품(10)은 지지수단(20) 위에 고정된다.As shown in FIGS. 3A and 3B, the casting 10 is cast and the casting 10 is fixed on the supporting means 20 when entering the desalting process.

탈사공정의 초기에는 상기 지지수단(20) 위에 상기 주조품(10)이 놓이게 되고 상기 타격수단(30)과 탄성부재(50)는 작동하지 않는다.In the initial stage of the desalination process, the cast product 10 is placed on the support means 20, and the striking means 30 and the elastic member 50 do not operate.

이후, 탈사 공정이 시작되면 상기 주조품(10)의 상면에 탈사 해머(60)가 아래 방향으로 타격한다.Thereafter, when the spinning process starts, the spinning yarn 60 hits the upper surface of the casting 10 in the downward direction.

상기 탈사 해머(60)의 힘에 의해 상기 주조품(10)이 타격되면서 상기 주조품(10)의 하면의 상기 지지수단(20)이 아래 방향으로 움직이면서 상기 탄성부재(50)를 누르게 되고 동시에 상기 타격수단(30)이 솟아오른다.While the casting 10 is hit by the force of the desalination hammer 60, the support means 20 on the bottom of the casting 10 moves downward and presses the elastic member 50, and at the same time, the hitting means. (30) swells.

상기 타격수단(30)이 솟아오르면서 상기 주조품(10)에 형성된 홀(25)을 관통하여 상기 주조품(10)의 내부의 주물사를 직접 파쇄하고 되고 탈사성을 높이게 된다.The blow means 30 rises and penetrates through the hole 25 formed in the casting 10 to directly crush the casting sand inside the casting 10, thereby increasing desorption.

본원 발명에 따른 주조품 탈사장치는 주조품에 부착된 주물사를 별도로 설치된 타격수단에 의해 직접 타격하여 제거할 수 있으므로 복잡한 구조를 갖는 주조품의 탈사문제를 해결할 수 있는 효과가 있다.Casting degassing according to the present invention can be removed by directly hitting the casting sand attached to the casting by a separately installed blow means has an effect that can solve the problem of the removal of the casting having a complicated structure.
