AI Technical Summary

Technical Problem

When lifting high-temperature metal molds, existing magnetic clamps cannot fully adhere to the uneven surface of the molds, resulting in unstable adhesion and a potential safety hazard of falling.

Method used

A magnetic clamp was designed. Multiple electromagnets were installed at the bottom of the end plate, and the positions of the electromagnets were adjusted by using a limiting slide and an electric push rod to make them fit the flat surface of the mold. At the same time, a servo motor was used to drive the limiting plate to rotate to enhance the limiting of the mold and ensure stable hoisting.

Benefits of technology

This improved the adhesion and hoisting stability of the electromagnet, avoiding the risk of high-temperature metal molds falling during transfer, and enhancing safety and operational reliability.

Abstract

This utility model relates to the field of metal mold processing technology, specifically a magnetic clamp for gripping high-temperature metal molds. It includes an end plate, with multiple evenly distributed electromagnets mounted on both sides of the bottom of the end plate. A first limiting groove is formed at the bottom of the end plate corresponding to the electromagnets, and a matching first limiting slider is inserted into the inner cavity of the first limiting groove. The bottom of the first limiting slider is fixedly connected to the electromagnet. First electric push rods are fixed at both ends of the end plate corresponding to the first limiting groove. The push rod of the first electric push rod movably passes through the end face of the end plate and is fixedly connected to the side wall of the first limiting slider. This utility model, by setting multiple electromagnets at the bottom of the end plate and using the first electric push rods to drive the multiple electromagnets to adjust their positions, allows the electromagnets to move to a flat area of ​​the mold surface when adsorbing, resulting in high adhesion and improved magnetic adsorption clamping stability.
