Plastic stretch blower not equal distance clamping device

(CN2709144Y )
Plastic stretch blow-molding machines include a rack and rack-mounted front, middle, and rear molds. Each template is connected by a guide rod, a mold clamping cylinder is mounted on the rear mold plate, a piston rod of the cylinder is connected to the transmission mechanism to drive the middle mold plate, a gear fixing plate is mounted on the rack, a gear shaft is mounted on the gear fixing plate, and the shaft is mounted on the shaft. The pinion gear and the bull gear are mounted on the rear rack at the lower part of the rear plate. The middle rack is equipped with a middle rack and the middle rack and pinion are matched. The rear rack and the large gear are matched. The main feature of this device is that the small gear and the large gear are installed on the same shaft. Because the diameters of the two are different, the strokes of the corresponding racks are not the same, and finally the middle and front are driven. The distances between the templates are not the same and they are not equidistant. However, the molds are opened on both sides so that the forming containers do not stick to the molds. The quality is ensured. The length of the former template is long and the container is easy to take.
