Abstract

본 발명은 사출성형기의 형체장치 크기를 최소화하고 작동유를 적게 사용하면서 고압의 형체력을 발생시킬 수 있도록 한 사출성형기의 형체장치에 관한 것이다.The present invention relates to a molding apparatus of an injection molding machine which minimizes the size of the molding apparatus of the injection molding machine and generates a high pressure clamping force while using less hydraulic fluid.

본 발명의 구체적인 수단은, 형체장치가 재치되는 베이스를 따라 부스트실린더에 의해 고정형판측으로 이동하는 이동형판을 관통하는 타이바를 맞물림 또는 해제하고 가이드바에 지지된 하프너트를 갖춘 사출성형기에 있어서, 상기 이동형판과 각각 한쌍의 하프너트의 사이에는 경사판과 웨지를 내장하는 웨지함체가 이도형판측에 고정설치되고, 상기 경사판은 중앙에 관통된 통공이 형성되어 타이바가 삽통가능하도록 하며, 그 일측면이 평면으로 하프너트와 접하고 타측면이 슬라이딩되는 경사면을 형성하여 웨지의 경사면과 슬라이딩되어서 상기 웨지함체내부에서 수평방향으로 슬라이딩 가능하게끼워맞추어져 있고, 상기 웨지는 상기 경사판과 슬라이딩 되는 경사면을 갖고 또 타이바에 간섭을 방지하도록 개구부가 형성되어 웨지작동용 실린더와 연결되어 있는 것을 특징으로 한다.A specific means of the present invention is an injection molding machine having a half nut supported by a guide bar by engaging or releasing a tie bar passing through a movable plate moving to a stationary plate side by a boost cylinder along a base on which a mold clamping device is placed. Between the plate and each of the pair of half nuts, a wedge box incorporating the inclined plate and the wedge is fixed to the side of the ear canal plate. It forms an inclined surface in contact with the half nut and the other side is slid so as to slide with the inclined surface of the wedge so as to be slidably fitted in the wedge box in a horizontal direction. The opening is formed to prevent the wedge acting cylinder And it characterized in that the connection.

Claims (1)

형체장치가 재치되는 베이스를 따라 부스트실린더에 의해 고정형판측을 이동하는 이동형판을 관통하는 타이바를 맞물림 또는 해제하고 가이드바에 지지된 하프너트를 갖춘 사출형성기에 있어서, 상기 이동형판(6)과 각각 한쌍의 하프너트(10~13)의 사이에는 경사판(18)과 웨지(19)를 내장하는 웨지함체(14~17)가 이동형판(6)측에 장착되고, 상기 경사판(18)은 중앙에 관통된 통공(18a)이 형성되어 타이바(1)가 삽통가능하도록 하며, 그 일측면이 평면(18b)으로 하프너트(10~13)와 접하고 타측면이 슬라이딩되는 경사면(18c)을 형성하여 웨지(19)의 경사면(19a)과 슬라이딩되어서 상기 웨지함체(14~17)내부에서 수평방향으로 슬라이딩 가능하게 끼워맞추어져있고, 상기 웨지(19)는 상기 경사판(18)과 슬라이딩되는 경사면(19a)을 갖고 또 타이바(1)에 간섭을 방지하도록 개구부(19b)가 형성되어 웨지작동용 실린더(C1,C2)와 연결되어 있는 것을 특징으로 하는 사출형성기의 형체장치.In the injection molding machine having a half nut supported by the guide bar and engaging or releasing the tie bar passing through the movable plate moving by the boost cylinder along the base on which the mold clamping device is placed, each paired with the movable plate 6 Between the half nuts (10 to 13) of the wedge box (14 to 17) containing the inclined plate 18 and the wedge 19 is mounted on the movable plate 6 side, the inclined plate 18 penetrates in the center The through hole 18a is formed so that the tie bar 1 can be inserted into the wedge by forming an inclined surface 18c in which one side thereof is in contact with the half nuts 10 to 13 in a plane 18b and the other side is slid. Sliding with the inclined surface (19a) of the (19) is fitted so as to slide in the horizontal direction in the wedge box (14 ~ 17), the wedge (19) is inclined surface (19a) sliding with the inclined plate (18) And openings to prevent interference with tie bars 1 19. A clamping apparatus for an injection molding machine, characterized in that 19b is formed and connected to the wedge operating cylinders C1 and C2. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
