NOVELTY - The utility model claims a mould pressing device for preparing heat conducting sheet of graphene fibre orientation arrangement, comprising: an upper top plate; a lower bottom plate; an upper pressing plate; a pushing mechanism; further comprising a locking unit, which is set on one side of the working part of the pushing mechanism; the locking unit comprises: a hinge body; a first connecting rod; a second link; a push rod; the push rod, the first connecting rod and the second connecting rod are on a plane; the working part of each pushing mechanism is provided with at least two locking units in the circumferential direction. The utility model claims a mould pressing device for graphene fibre orientation arranged heat conducting sheet, which can realize long-time pressure maintaining only by the locking unit. compared with directly through hydraulic pressure and air pressure mechanism to keep pressure, without continuously providing power to the pushing mechanism, the structure is simple and reliable, it will not cause long time burden to the hydraulic or pneumatic system so as to increase the service life of the hydraulic or pneumatic system.
