Abstract
Provided is a magnetic clamp device that reduces a magnetic flux leaking from a magnetic circuit passing through a permanent magnet and a magnetic pole member. The magnetic clamp device includes: a permanent magnetsurrounding a magnetic pole memberand disposed on a surface of a plate PL made of a magnetic body that magnetically clamps a mold in a magnetized state; and a reversible magnetcapable of reversing polarity and disposed at the rear of the permanent magnet. The magnetic pole memberis constituted by a plurality of magnetic pole pieces, and. Each of the magnetic pole pieces has a first lateral surface R with a shape corresponding to the opposite permanent magnet, and a second lateral surface T at which adjacent magnetic pole pieces oppose each other. The magnetic pole membermoves as the first lateral surfaces R are suction-adsorbed by the permanent magnetwithout the second lateral surfaces T interfering with each other. The magnetic pole pieces, andare held from the front and rear.
