Lubricating oil is filled in the sliding hole to reduce friction force. The base 3 is also supported on the pair of cylindrical beams 2 by sliding holes inside the base, is positioned between the pair of sliding seats 1, and is limited by the pair of sliding seats 1. A gap is reserved between the base 3 and the sliding seat 1, so that fine adjustment is facilitated. A pair of vertical support plates 7 are mounted on the base 3 for supporting the turret 4.

A boss 44 is installed at the center of the outer side of one of the rotary plates 41, and a circle of screw holes are processed on the end face of the boss 44 for connecting with a speed reducing mechanism. The speed reducing mechanism is driven by a servo motor, so that the control precision of the speed reducing mechanism is improved.
The blow molding mold generally comprises a front mold 8 and a rear mold 9, and in order to facilitate the synchronous control of the opening and closing of the front mold and the rear mold, the mold and the synchronous template 5 are distributed on two sides of the rotary seat 4 along the direction of the cylindrical beam 2.
