PURPOSE:To prevent an inverted U-shaped member and a flange member from breaking, twisting by locating the inverted U-shaped member around the flange member in such a state that both insides of the inverted U-shaped member in the front and rear direction come in no contact with both sides of the flange member in the front and rear direction. CONSTITUTION:The flange member 17a of a docking pin 17 is engaged with the inverted U-shaped member 19 and the small diameter section 17b of the docking pin 17 is inserted into a U-shaped groove 19a. The inverted U-shaped member 19 is provided detachably to the docking pin 17 in the vertical direction and a play shown by t1 is prepared between the inverted U-shaped member 19 and the flange member 17a. Accordingly, since a lower mold member is pushed a little by a pusher 28a to give a distance between the inverted U-shaped member and the flanged member, in the connecting section of the lower mold member to its driving gear side both the inverted U-shaped member and the flange member are detached in the descending time as well as in the ascending time so that the mutual plays are parted to both sides. Therefore, detachment from the molding machine becomes easier and the connecting member is free from abrasion, breakage, torsion etc.
