PROBLEM TO BE SOLVED: To render the mechanism simple, and facilitate the removal work of a molded item. SOLUTION: The clamping process is carried out by rotating nut members 9 in a normal direction via a transmission mechanism 14 by making a brake 26 on and a brake 25 off and rotating a driving shaft 21 in a normal direction by means of a driving source 21. Also, the clamping process is conducted by rotating the nut members 9 in a normal direction by making the brake 25 on and brake 26 off and rotating a driving shaft 22 in a counter direction by means of a driving source 24. After obtaining a desired clamping forces, a clamping state is kept by making the brake 26 on and stopping the driving source 24. The mold releasing process is effected by rotating the nut members 9 in a counter direction by making the brake 26 off and rotating the driving shaft 22 in a normal direction by the driving source 24 in a state described above. In addition, the mold opening process is executed by rotating the driving source 23 in a counter direction in a state of the clamping process. |
