| description | According to one embodiment of the present invention, a molding device is configured such that a material is introduced between mold cavities divided by upper and lower core plates, and a mold having a predetermined thickness is injection-molded. The molding device comprises: a gas injection unit which includes a piston provided so as to be movable therein and enables gas filling the inside of the cylinder to be injected into a space between the mold cavities by means of the movement of the piston; a cam member which is connected to the piston and provided to adjust a moving distance of the piston by means of the eccentric rotation; a connecting rod which has one end that is in contact with and supported by a rotational surface of the cam member and is reciprocated by the eccentric rotation of the cam member; and a gas injection amount control unit which is connected to a cross-section of the cam member and moves the connecting rod by rotating the cam member such that the amount of gas filling the gas injection unit so as to be injected into the space between the mold cavities is controlled. According to the present invention, during injection molding, a separate gas compression/injection device is not required, thereby reducing costs.
본 발명의 일 실시예에 따른 금형 장치는, 상하부 코어 플레이트에 의해 나뉘어진 금형 캐비티 사이에 재료가 투입되어 소정의 두께를 가지는 금형이 사출 성형되도록 하는 금형 장치로서, 피스톤이 내부에서 이동가능하도록 구비되며, 상기 피스톤의 이동에 의해 실린더 내부에 충진된 가스가 상기 금형 캐비티 사이의 공간에 주입되도록 하는 가스 주입부와, 상기 피스톤과 연결되고, 편심 회전에 의해 상기 피스톤의 이동 거리를 조절하도록 구비된 캠 부재와, 일단이 상기 캠 부재의 회전면에 접촉하여 지지되고 상기 캠 부재의 편심 회전에 의해 왕복 이동되는 커넥팅 로드, 및 상기 캠 부재의 단면에 연결되고, 상기 캠 부재를 회전시켜 상기 커넥팅 로드를 이동시킴으로써 상기 가스 주입부에 충진된 가스가 상기 금형 캐비티 사이의 공간으로 주입되는 가스 주입량을 조절하도록 구비된 가스 주입량 제어부를 포함한다. |
