Abstract

본 발명은 사출성형기의 가압장치에 관한 것으로, 고정플레이트에 형성하고 있는 다수개의 실린더에 콤프레셔와 압력을 전달하여 고정플레이트에 있는 이동형판 조정 실린더를 가압하면 한쌍의 금형이 결합을 한다.The present invention relates to a pressurizing device of an injection molding machine, and a pair of molds are coupled by pressing a moving cylinder adjusting cylinder on a fixed plate by transferring a compressor and pressure to a plurality of cylinders formed on a fixed plate.

그리고 셔터를 형체 램의 측면에 위치하게 하고 고정플레이트에 있는 커버의 유체호울에 압력을 가하면, 형체램에 작용한 F가 셔터를 밀면서 지지대를 통해 금형을 더욱 밀착시킨다. 이와같이 작업이 끝난후에는 역순으로 작동하여 완성품을 금형으로부터 분리시킨다.When the shutter is placed on the side of the clamping ram and pressure is applied to the fluid hole of the cover on the fixed plate, F acting on the clamping ram pushes the shutter and the mold is brought into close contact with the mold. In this way, after the work is completed, the product is operated in the reverse order to separate the finished product from the mold.

상기와 같은 방법은 다수개의 타이바아와 로드만으로 한쌍의 금형을 결합하는 것 보다 고정플레이트의 가운데에 별도의 가압장치를 형성하여 압축하면 미세한 틈이 없어지므로해서 불량발생률이 적어지며, 압축부의 넓은 단면적에 의한 분포하중으로 금형의 변형이 적고 정밀금형이 수명이 연장되는 효과가 있다.In the above method, rather than combining a pair of molds with only a plurality of tie bars and rods, a separate pressurizing device is formed in the center of the fixing plate to compress and eliminate the minute gap, thereby reducing the incidence of defects. Due to the distributed load, the deformation of the mold is small and the precision mold has the effect of extending the life.
