AI Technical Summary
In the existing technology, the use of TPX material for the core makes the process of removing the core from the automotive air conditioning hose cumbersome, labor-intensive, and requires heating the core to increase the gap, making the process complicated.
A convenient quick demolding device for hose forming mandrels was designed. It adopts a connecting mechanism and a limiting mechanism to simplify the demolding process, reduce the labor intensity of workers, and achieves quick demolding through a hydraulic cylinder, drive motor and worm gear transmission system, eliminating the step of heating the mandrel.
This simplifies the hose core removal process, reduces labor intensity, improves efficiency, increases the number of times the core can be reused, and eliminates the need to heat the core.
