AI Technical Summary
Existing special carbon material molding presses lack a buffer mechanism during pre-pressing and pressing processes, resulting in excessive impact force, which causes the material to be brittle, cracked, and damaged, affecting the molding quality.
A hydraulic cylinder drives the slide plate to move the buffer assembly, which includes a damper, a telescopic spring, and a disc spring. The buffer assembly buffers the impact force and gradually transmits the pressure. Combined with the polyurethane pad and disc spring of the top mold assembly, it buffers the demolding process and avoids rigid extrusion.
It improves the pre-pressing and pressing quality, stability, and smoothness of the demolding process of special carbon materials, avoids material damage, and enhances the quality of molded products.
