The invention discloses an electric permanent magnetic chuck capable of realizing quick die exchange. The electric permanent magnetic chuck comprises a fixed die plate and a movable die plate, wherein a positioning hole and a positioning ring are arranged in the middle of the fixed die plate; the movable die plate is provided with a positioning pin; die holes are formed in the fixed die plate and the movable die plate, and proximity switches, temperature sensors and magnetic sensors are arranged in the die holes; magnetic assemblies and cover plates are arranged in the die holes, and lead slots are formed in the cover plates; proximity switch indicator lamps, hazard warning lamps and aerial linker joints are arranged on side surfaces of the fixed die plate and the movable die plate; the proximity switches, the temperature sensors, the magnetic sensors, magnetic induction loops, the proximity switch indicator lamps and the hazard warning lamps are connected with the aerial linker joints through power lines respectively; the aerial linker joints are connected with a controller through the power lines; and the controller is connected with a manual control box and an external power line through the power lines. The product has good magnetic absorption, die screw installation is avoided, the machining cost is reduced, the die exchange time is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a mold fixing plate, in particular to an electro-permanent magnetic sucker for quick mold change. Background technique [0002] The mold of the product is composed of several pieces, and each mold must be equipped with several bolt holes, and the molds are clamped by bolts before injection molding, which increases the time for mold opening and tapping, increases the cost of mold opening, and increases the cost of mold opening Consumables are troublesome to install when used; it is troublesome to replace, adjust, and overhaul molds during use, and dismantling after use increases personnel costs and other shortcomings. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an electro-permanent magnetic chuck for quick mold change, fast installation, no need for mold tapping, good magnetic attraction, saving processing costs, saving mold replacement and adjustm...
