ABSTRACT:
An apparatus for replacing the tool sets without requiring any fixing or removal of the fluid pressure pipes such as hydraulic hoses or the like when the tool sets are fixed to or removed from the main body of the power molding press. Swing arms 6 having arm lengths set therein are oscillatably and rotatably fitted to the arm shafts 5 vertically installed at proper side locations of the main body 1 of the press in such a way as the rotating radius of the arm shafts may overlap the mounting position of the main body 1 of the press. The extreme ends of the swing arms 6 are provided with supporting boxes 7 on which the tool sets 3 are mounted. Rotation of the swing arms 6 enables the tool sets 3 to be moved toward or away from the centeral part of the main body 1 of the press and then the tool sets 3 to be fixed to or removed from the main body 1 of the press. The fluid pressure pipe passages for driving the tool sets 3 are connected in advance to the operating fluid pressure source at the main body 1 of the press near the aforesaid arm shafts 5 through the joint means following the rotation of the aforesaid swing arms 6.
