AI Technical Summary

Technical Problem

When the pressing mold is returned, the workpiece is prone to stuck inside the mold cavity, resulting in delays in working progress and reduced efficiency.

Method used

A press-fit mold material retraction structure is designed, including a frame, hydraulic column, material retraction mechanism, lower mold assembly, upper mold seat and movable parts. The material withdrawal mechanism pushes the workpiece out of the mold cavity through the cooperation of the electric telescopic rod, the round rod and the round plate; the movable component uses the cooperation of the top plate, the top rod, the baffle and the spring to lift the top plate to help the workpiece move out of the mold cavity.

Benefits of technology

Through the synergy between the material withdrawal mechanism and the movable parts, the workpiece is effectively prevented from being embedded in the mold cavity, and the workpiece is successfully retracted, improving work efficiency and production progress.
