Abstract
The present invention is lubricant oil circulating path structure for elbow joints in injection molding machine. The elbow joint mechanism comprising upper and lower movable arms corresponding to the fixed tailstock pushes the movable mold seat for closing with the fixed mold seat, and the upper and lower movable arms are pivoted mutually through shaft lever with oil hole communicated to the oil path. In the joint between the upper and the lower movable arms, there is one connecting oil pipe for communicating the oil paths in the upper and the lower movable arms. The lubricant oil circulating path structure can lubricate the elbow joint mechanism and take out the impurity generated during actuation.
