<p><P>PROBLEM TO BE SOLVED: To realize a biaxially stretching blow molding machine having a high processing speed by accelerating the speed of the opening and closing operation of a pair of stretching molding dies. <P>SOLUTION: In the stretching molding unit 5 of the biaxially stretching blow molding machine 1, a mold clamping mechanism 53 for opening and closing the pair of the stretching molding dies 51 and 52 completely synchronizes a pair of toggle linking mechanisms 54 and 55 for opening and closing the pair of the stretching molding dies 51 and 52 and moves them in a reverse direction by utilizing the movement of the fluctuating plate of a common fluctuating mechanism 56 at symmetrical position from the fluctuating center, and moves them in opposite direction. Accordingly, a radical load is not generated in each part of the mold clamping mechanism 53 at the time of opening and closing the dies, and an evil such as occurrence of abrasion of each part, application of impact force to each part, etc. can be avoided. Therefore, smooth and rapid mold opening and closing operation can be realized. As a result, the operating speed of the biaxially stretching blow molding machine 1 can be accelerated. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
