Professional Plastic Pipe Fitting Mould Manufacturer With 20 Years Of Experience - Spark Mould
1 inch Nut Union Fitting Mould - Spark Mould
This is Nut union fitting mould. The product has threads inside, and we designed an automatic thread removal structure. The drive mode is that the rack pull rod drives the thread core to rotate. The pull rod is powered by a hydraulic cylinder, so the stroke of the hydraulic cylinder is relatively long.
Automatic unscrewing thread mechanism with rack drive
The meshing transmission between the rack and the gear is the core part of this mold. The rack drives the gear to rotate through linear motion, thereby realizing the rotation of the threaded core.
When designing the mold, it is necessary to consider parameters such as transmission ratio, modulus, pressure angle, etc. to ensure the smoothness and accuracy of the transmission.

The hydraulic cylinder drives the rack to move linearly. The rack drives the thread core to rotate through the gear meshing with it. At the same time, during the rotation process, the thread core moves axially in the opposite direction of the plastic part thread and gradually separates from the threaded part of the plastic part.
