Split type helical structure injection mold and demolding method
By using a split spiral structure injection mold and demolding method, and utilizing a demolding mechanism with a sliding block and groove, along with high-frequency vibration and spraying of a demolding agent, the problems of insufficient spiral structure strength and difficulty in mold release agent penetration are solved, achieving a fast and effective demolding process, reducing scrap rate and improving demolding efficiency.

AI Technical Summary
When the mandrel is removed as a whole, the thin wall thickness of the existing spiral structure injection mold results in insufficient strength of the spiral structure, which easily damages the spiral structure, increases the scrap rate, and makes it difficult for the release agent to enter the mandrel, affecting the demolding effect.
A split spiral structure injection mold and demolding method are adopted. Through the split spiral mandrel design and demolding mechanism, the four sets of mandrels are successfully demolded by using the cooperation of sliders and grooves. Combined with the high-frequency vibration of the demolding head and the spraying of the demolding agent, the integrity of the spiral structure and the demolding effect are ensured.
It achieves a fast and balanced demolding process even with thin spiral structure walls, reducing scrap rate, improving demolding efficiency, and ensuring full coverage of the release agent to protect the spiral structure of the molded part from damage.
