AI Technical Summary
Existing 3D printed sand core hoisting structures suffer from low layout rate, unstable quality, high production loss, and safety hazards. Furthermore, the maximum size limit of the automated warehouse prevents oversized sand cores from being stored.
Design an ultra-large 3D printed sand core hoisting structure, which adopts a self-locking connection of hoisting handle, support rod and fixing rod, which are self-lockingly connected to the sand core. The hoisting handle is made of ductile iron. The self-locking and strength enhancement of the hoisting structure are achieved through the inclined design and the sliding groove structure.
It improves the overall strength and patterning rate of the sand core, reduces the risk of damage to the lifting handle, realizes the flexibility and reusability of the lifting handle, reduces production costs, and solves the problem of sand core size exceeding the standard.
