4 Cavities PVC Long Sweep 90 Degree Elbow Mold

The characteristic of Long Sweep 90 elbow is that it has a longer bending radius. Specifically, the curvature radius of the long sweep 90 elbow is usually 1.5 times the diameter of the pipe. This design allows the fluid to flow more smoothly when passing through the elbow, reducing fluid resistance and pressure loss. This 90 degree elbow usually has hubs at both ends.

The core of this set of 90 degree elbow mold is the rotating tie rod mechanism. It includes tie rod, rotating tie rod joint, plane bearing and fixing ring. During the pulling process, the tie rod realizes smooth rotation through the cooperation of rotating tie rod joint and plane bearing. The fixing ring is used to fix the plane bearing on the tie rod to ensure the stability and reliability of the rotation.

As shown in the video on the right. During the mold opening process, the angle pin drives the sliders on the upper and lower sides of the movable mold to move a certain distance. Then the hydraulic cylinder pulls the connecting rod, and the connecting rod drives the slider to rotate. The linear motion of the pull rod is converted into rotational motion.
