Pipe Elbow Mould
Pipe elbows are key connectors used to change the direction of pipes. They feature a variety of standard angles (such as 45°, 90°, and 180°) and bend radii (such as long radius and short radius). To efficiently and accurately mold these plastic parts, pipe elbow molds are specifically designed with a core-pulling mechanism based on elbow specific structural characteristics. This ensures the elbow's internal shape is fully formed and allows for smooth ejection.

This 45 degree elbow mold is a 3-plate mold mechanism. The core pulling mechanism is relatively complex. The product material is black PVC material.
In view of the unique O-ring interface structure at one end of the 90 degree elbow, we innovatively adopted two different foldable core mold mechanisms.
The 90-degree joint has core pulling in two directions. We have designed a folding core and angle pin core pulling mechanism. To make the product release from the mold smoothly ,we designed and manufactured three pivoting core inserts. It depends on the arc length of the elbow and it has two straight area. The only disadvantage of this structure is that the mold core cannot carry cooling. Only used the method of external cooling .
The J-type elbow has two directions of ejection mechanism, one is the hollow structure inside the tube, and the other is the lateral protruding hole. Therefore, we adopted the design of collapsible core and angle pin core pulling mechanism. It not only ensures the precise molding of the inner cavity of the product, but also effectively improves the adaptability of the mold.
This innovative 180-degree elbow mold is designed to solve the production problems of PVC elbows with long straight sections and difficult demolding. The uniqueness of this mold lies in its foldable core technology, which allows the mold to easily ejection while maintaining high-precision molding. This mold is suitable for PVC materials and has good corrosion resistance, wear resistance and service life.
