Abstract
A direct pressing clamp mould mechanism for heat pressing machine comprises mainly a pair of side plates fixed on a stander, a static mould base between upper end of two side plates, a clamp mould mechanism arranged on the stander and a movable mould base arranged on the clamp mould mechanism, wherein, the clamp mould mechanism is an oil pressing tank. A piston of the oil pressing tank comprises a platform, the top of which is provided with the movable mould base. A side wall is connected with the circumference of the platform and extends into the interior of the oil pressing tank. An oil liquid space comprises the platform and the side wall. The action oil of the oil pressing tank is filled in the oil liquid space. The movable mould base and mould driven by the clamp mould mechanism has a deformation mode of inclined to the static mould base. Therefore, once the lock mould reversal force undertaken by the platform is uneven due to deformation of the static mould base, the pressing stress of the action oil makes the platform zone of little stress deform accordingly, thereby printing the decorative pattern on mould plane on the final product completely.
