Abstract
A plastic magnet injection molding machine comprises a stationary platen side and a movable platen side block each made of a ferromagnetic material and fixed to or integrated with a stationary and a movable platen, a stationary platen side and a movable platen side exciting coil arranged at the outer circumferences of respective ferromagnetic blocks, and a stationary platen side and a movable platen side cover each made of a non-magnetic material and attached to respective platens so as to surround the outer circumferences of the respective exciting coil and ferromagnetic block. The stationary platen side ferromagnetic block and non-magnetic cover have, respectively, surfaces each being in opposition to the movable platen and being flush with each other in a single plane parallel with the stationary platen. The movable platen side ferromagnetic block and non-magnetic cover have, respectively, surfaces each being in opposition to the stationary platen and being flush with each other in a single plane parallel with movable platen. Both of the single planes are formed with bolt holes for fitting stationary and movable molds, respectively.
