Abstract
A support device for a movable die comprises a linear guide, a base, a movable platen, a driving mechanism which linearly moves the base, and a securing mechanism which secures the movable platen to the base. The base is guided by the linear guide and is linearly movable. A movable die is mounted to the movable platen, and the movable platen is mounted on the base. When the movable platen undergoes a deformation with a pressure of die clamping, the securing mechanism absorbs a displacement of the movable platen in a base movement direction or a vertical direction due to the deformation.
Claims14
A support device for a movable die, comprising:
- a linear guide;
- a base which is guided by the linear guide and which is linearly movable;
- a driving mechanism which linearly moves the base;
- a movable platen which is mounted on the base and which is configured to hold the movable die;
- and
- a securing mechanism which secures the movable platen to the base and which, when the movable platen undergoes a deformation with a pressure of die clamping, absorbs a displacement of the movable platen in a base movement direction and a displacement of the movable platen in a vertical direction due to the deformation.
A support device for a movable die, comprising:
- a linear guide;
- a base which is guided by the linear guide and which is linearly movable;
- a driving mechanism which linearly moves the base;
- a movable platen which is mounted on the base and which is configured to hold the movable die;
- and
- a securing mechanism which includes
- a first securing mechanism which secures the movable platen to the base and which, when the movable platen undergoes a deformation with a pressure of die clamping, absorbs the displacement of the movable platen in the vertical direction;
- and
- a second securing mechanism which secures the movable platen to the base and which, when the movable platen undergoes a deformation with a pressure of die clamping, absorbs the displacement of the movable platen in the base movement direction.
A die-clamping unit comprising:
- a stationary platen configured to hold a stationary die;
- a movable platen configured to hold a movable die, and capable of advancing toward and receding from the stationary platen;
- a die-clamping mechanism which presses the movable platen against the stationary platen, and thereby die-clamps the stationary die and the movable die together;
- a base having the movable platen mounted thereon;
- a linear guide which linearly movably guides the base;
- a driving mechanism which linearly moves the base;
- and
- a securing mechanism which secures the movable platen to the base and which, when the movable platen undergoes a deformation with a pressure of die clamping, absorbs a displacement of the movable platen in a base movement direction and a displacement of the movable platen in a vertical direction due to the deformation.
