Abstract
The invention discloses a mold clamping mechanism of a blow molding device. A self-locking position which is located on the other side of a hinged shaft of a swing arm is arranged at the tail end of a sliding way. Rollers of a roller assembly drive the swing arm to swing so as to drive a shifting shaft to move relative to the sliding way when rolling along a mold clamping guide rail. The shifting shaft drives a connection block and a mold clamping shaft component to descend when moving from the start end of the sliding way to the tail end of the sliding way. A bolt downwards quits from an insertion hole and self locking is achieved when the shifting shaft moves into the self-locking position of the sliding way. According to the mold clamping mechanism, a lock nose hole and a mold clamping pin capable of being inserted in the lock nose hole in the prior art are not needed, and strong impact and high noise which are generated generally in the prior art are also avoided. Meanwhile, the situation that work is unstable and unreliable, the service life of the mold clamping mechanism is short in the prior art can not occur.
