90 Degree Elbow With Rubber Ring Port - Spark Mould

We designed two collapsible core-pulling mold mechanisms for this 90 degree elbow injection mold. One is used to solve the O-ring at the elbow port. The other realizes the core-pulling ejection of the elbow itself. During the product ejection process, the slide at the O ring shrinks first. Then it is separated from the product along with the slide inside the elbow. The difficulty in designing this mold case lies in the coordination of the slider movements of these two parts. The product is made of black PVC.

    The collapsible core is an innovatively designed mold core pulling mechanism. It is cleverly composed of 9 carefully designed parts. The mechanism has efficient folding and unfolding functions. The mold structure is used to achieve threads or annular flaring inside plastic parts.

    Chain Core Structure

    The chain core structure is cleverly designed, consisting of three precise arc blocks and guide rails. These arc blocks can move flexibly along the guide rails to achieve free switching of the core pulling action, with extremely high mechanical coordination and stability.
