Die clamping system

A die clamping system comprising:

• a fixed die plate,
• a moveable die plate moveable in an opening and closing direction with respect to the fixed die plate,
• a tie bar inserted into said fixed die plate and said moveable die plate and able to be withdrawn from said fixed die plate,
• a die opening and closing part moving said moveable die plate in the opening and closing direction,
• a withdrawing part having a moveable part capable of being coupled with said tie bar, provided on said moveable die plate, and moving said moveable part with respect to said moveable die plate in the withdrawing direction of said tie bar, and
• a withdrawing coupling part coupling said moveable part and said tie bar and releasing the coupling action, and
• a control part controlling operations of said withdrawing coupling part, said die opening and closing part, and said withdrawing part so that in the state of coupling through said withdrawing coupling part, said die opening and closing part moves said moveable die plate in said die opening direction and said withdrawing part moves said tie bars in the withdrawing direction.

• a die opening and closing part moving said moveable die plate to the opening and closing direction,
• a withdrawing part having a moveable part capable of being coupled with said tie bar and moving said moveable part in the withdrawing direction of said tie bar,
• a withdrawing coupling part for engaging said moveable part and said tie bar, and
• a control part controlling operations of said moveable die plate coupling part, said withdrawing coupling part, said die opening and closing part, and said withdrawing part so that in the state of coupling by said moveable die plate coupling part, said die opening and closing part moves said moveable die plate in said die opening direction, and then, in the state of releasing the coupling action by said moveable die plate coupling part and coupling by said withdrawing coupling part, said withdrawing part moves said moveable part in the withdrawing direction.
