Advantages: high precision, no thermal deformation, energy saving. Classification: There are three main types of electric permanent magnetic chucks: ordinary rectangular electric permanent magnetic chucks, strong rectangular electric permanent magnetic chucks, and round electric permanent magnetic chucks. Electric permanent magnetic chucks are mainly used in production for rapid mold change of injection molding machines or ceramic dry presses, metal cutting, and magnetic lifting to transfer and transport heavy metal objects.

[0003] The patent specification with the announcement number CN216212691U discloses an electric permanent magnetic chuck controller with an anti-collision structure, which includes a box body, a box cover is hinged on the upper end surface of the box body, a sealing gasket is filled in the gap between the box cover and the box body, and the sealing gasket ring is arranged on the outer wall of the box cover, an observation window is embedded in the middle of the box cover, a storage bin is arranged at the lower end of the box body, a controller is arranged at the upper end of the inner part of the box body, a console is arranged at the upper end of the controller, a center plate is fixed inside the box body; a motor is installed on the upper surface of one end of the center plate. It drives the gear meshing sawtooth rod to move up and down through the motor, so that the controller can move up and down at the upper end of the inner part of the box body, thereby achieving the effect of storing and protecting the controller. When the controller is stored in the box body, it does not have direct contact with the collision source, and the anti-collision effect is better.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed electric permanent magnetic suction cup controller with an anti-collision structure has the following problems: the box cover and sealing gasket set in the above-mentioned technical scheme can improve the sealing of the upper surface of the box body when the box cover is closed, prevent dust and water stains from entering the interior of the box body from the upper end of the box body, prevent such pollutants from damaging the controller, and improve equipment safety. However, since the controller is installed in the box, the heat generated by the controller during operation cannot be discharged in time, reducing the service life of the controller. In view of this, a controller for a permanent magnetic suction cup with natural cooling is provided to overcome the above-mentioned defects. Utility Model Content
