This is a very classic 45 degree joint mold. The mold consists of two sets of core pulling mechanisms. One is controlled by a cylinder and the other is controlled by an angle pin.
The Hex Nut Bulkhead Fittings are designed with threads inside. In order to achieve smooth ejection of the product, we specially adopt collapsible core slider mechanism.
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 tube end cap injection mold adopts an automatic unscrew thread mold mechanism, which greatly optimizes the mold stripping process. The automatic thread stripping mold mechanism has a high degree of stability and reliability, which can ensure that each demoulding is accurate, further ensuring the quality and consistency of the tube end cap products. It can also reduce manual intervention and improve production efficiency.
Molding 180-degree return bends (J-Bends) with integrated threaded side inlets presents a classic plastic tooling challenge: achieving smooth core retraction from a deeply curved geometry without complex, high-maintenance rotational mechanisms.
The automatic unscrew thread mold is suitable for all pipe fittings with internal wall threads. We use an automatic unscrew thread mechanism driven by a hydraulic motor and gear transmission. This allows the threads to be ejection smoothly without damaging the threaded parts. Compared with traditional manual or mechanical stripping methods, the automatic thread stripping mechanism is not only easier and faster to operate.
This Tee joint mold adopts angle side core pulling mechanism, efficient production capacity and perfect adaptation to PVC materials, making it the preferred solution in the field of Tee-type pipe joint production. The angle pin side core pulling mechanism can save space and adapt to smaller machines. It ensures the stability and accuracy of the mold during the molding process.
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.
