Surface-mount type strong-magnetism electric control permanent magnet template with honeycomb array structure

Abstract

The invention discloses a surface-mount type strong-magnetism electric control permanent magnet template with a honeycomb array structure. The surface-mount type strong-magnetism electric control permanent magnet template is characterized in that a first strong-magnetism electric control permanent magnet system (2) is an orthohexagonal honeycomb unit structure; a second strong magnetic electric control permanent magnet system (3) is a rhombus structure; three rhombus units form one orthohexagonal honeycomb unit structure; a compound reversible strong-magnetism permanent magnet (34) is compounded by a reversible strong-magnetism permanent magnet (34a) and a magnetism conducting material (34b); a pulse coil (33) is coated on the external surface of the reversible strong-magnetism permanent magnet (34a); the polar surface of the magnetism conducting material (34b) is clung to the inner polar surface of a magnetism conducting substrate (31). The surface-mount type strong-magnetism electric control permanent magnet template is capable of utilizing the effective space to a maximum extent, so that the effective attraction force of the electric control permanent magnet in per unit of area is improved; the surface-mount type strong-magnetism electric control permanent magnet template with the honeycomb array structure is free of electromagnetic pollution to the surrounding environment.

Description

technical field [0001] The invention relates to the field of electro-permanent magnet technology of a magnetic fast mold change device, in particular to a honeycomb array structure mounting type strong magnetic electronically controlled permanent magnet template. Background technique [0002] At present, in industries such as injection molding, the installation, fixing, and clamping of injection molds often use mechanical, hydraulic, or pneumatic methods to fix the injection mold on the workbench template of the injection molding machine. These technologies and methods have more or less deficiencies, some have large structures and high costs, some have potential safety hazards, and some have damage or cause additional deformation to high-precision injection molds. Of course, electro-permanent magnetic chucks are also used as work fixtures, but they all use circular, square or rectangular magnetic systems, either due to loose arrangement and low suction safety factor, or insu...
