가스가 제1 돌출 구조물(110) 및 제2 돌출 구조물(115) 사이의 공간(130)에 발생할 경우 가스는 성형된 격벽에 공동을 발생시키거나 불균일면을 발생시키는 등과 같은 문제를 발생시키므로 얇은 격벽을 성형할 경우에는 격벽 형성을 위한 공간에 발생할 가스를 적절히 제거할 필요가 있다. When gas is generated in the space 130 between the first projecting structure 110 and the second projecting structure 115, the gas causes problems such as creating a cavity in the formed partition wall or generating a non-uniform surface. In the case of molding, it is necessary to appropriately remove gas to be generated in the space for forming the partition wall.
본 발명에서는 이러한 가스를 제거하기 위해 삽입 구조물(120)을 이용한다. 삽입 구조물(120)은 베이스 구조물의 홀에 삽입될 때 베이스 구조물과는 미세 갭(200)을 두고 삽입된다. 삽입 구조물(120)의 삽입부의 사이즈는 홀과 미세갭을 형성할 수 있도록 미리 설정된다. In the present invention, the insertion structure 120 is used to remove such gas. When the insertion structure 120 is inserted into the hole of the base structure, the insertion structure 120 is inserted with a fine gap 200. The size of the insertion portion of the insertion structure 120 is preset to form a micro gap with the hole.
도 3을 참조하면, 제1 돌출 구조물(110)과 제2 돌출 구조물(115) 사이 공간의 바닥부에는 미세 갭이 형성된다. 미세 갭은 액체인 용탕은 빠져나가지 않으며 기체인 가스는 빠져나가도록 그 크기가 설정된다. 예를 들어, 미세 갭의 간격은 0.05mm일 수 있다. Referring to FIG. 3, a fine gap is formed at the bottom of the space between the first projecting structure 110 and the second projecting structure 115. The fine gap is sized so that the molten metal does not escape and the gas, which is a gas, escapes. For example, the spacing of the fine gaps may be 0.05 mm.

The pressure control unit 300 is coupled to the gas receiving space 250 formed by the groove 410 of the insertion structure 120 to control the pressure of the gas receiving space 250. The pressure controller 300 lowers the pressure in the gas receiving space 250 so that the gas of the molten metal filled in the space between the first protruding structure 110 and the second protruding structure 115 passes into the gas receiving space 250. Through 200).
