The present utility model discloses a dustproof mechanism for an injection blow molding machine, comprising a first support, a second support, a first servo motor and a coupling. Mounting plates are bolted below the first support and the second support, a first servo motor is bolted outside the first support, a second servo motor is bolted outside the second support, grooves are formed on the outer surfaces of the second winding shaft and the first winding shaft, and ropes are connected inside the grooves. The dustproof mechanism for the injection blow molding machine is provided with a dustproof cloth, which can well cover the upper parts of the rear mold moving plate and the front mold fixed plate in cooperation with the first winding shaft and the second winding shaft during use, so as to prevent dust for the mold between the rear mold moving plate and the front mold fixed plate, thereby preventing dust from entering the mold from the opening above the injection blow molding machine, greatly increasing the practicability and functionality of the device, and avoiding product contamination by dust.
