Abstract

본 발명은 사출성형기에서 스크류실린더를 선회하는 장치에 관한 것으로, 특히 스크류실린더의 선회구조를 간략화시켜 스크류실린더의 분해 및 조립성을 개선한 사출성형기의 스크류실린더선회장치에 관한 것이다.The present invention relates to a device for turning a screw cylinder in an injection molding machine, and more particularly, to a screw cylinder turning device for an injection molding machine, which simplifies the turning structure of the screw cylinder and improves disassembly and assembly of the screw cylinder.

본 장치는 인젝션유닛의 높낮이 조절밸브를 제거하지 않고도 선회조작이 가능하여 작업시간이 단축되는 잇점을 갖는다. 또한, 롤러베어링을 장착하여 선회동작을 가이드하므로 선회시의 마찰력을 감소시켜 기기의 내구성을 향상시킬 수 있는 효과를 갖는다.This device has the advantage that the operation time can be shortened by allowing the turning operation without removing the height adjustment valve of the injection unit. In addition, it is equipped with a roller bearing to guide the swing operation has the effect of improving the durability of the machine by reducing the friction force during the swing.
