AI Technical Summary
In existing technologies, manually removing the sliders one by one results in high labor intensity and low efficiency.
Design a demolding mechanism for an impeller, including a demolding base, a first demolding component, and a second demolding component. The upper and lower sliders of the slider core-pulling mechanism are connected through a guide waist-shaped hole. By rotating the demolding component, the slider is driven to move away from the rotation axis, so as to realize the synchronous removal of the slider.
Multiple sliders can be pulled out simultaneously with a single rotation, reducing labor intensity and improving production efficiency.
