Abstract
A metal die casting machine having a safety bar mechanism for cushioning the stopping action of a movable platen when it is stopped prior to reaching the closed position of the dies. One embodiment provides a two-part bar connected together by a cushioning means. A second embodiment mounts a cushioning means on one of the platens, preferably the movable platen.
Claims27
In a die casting machine having a front platen, a rear platen, a movable platen located between said front and rear platens, an actuator for moving said movable platen between open and closed positions;
- and a safety bar mechanism operatively connected between said movable platen and said rear platen for stopping the movement of said movable platen short of said closed position as it is moving toward closed position;
- the improvement comprising:
- a cushioning mechanism associated with said safety bar to absorb the inertial forces generated by the movement of said movable platen toward said front platen as it is being stopped.
A safety bar of a die casting machine for connection between a stationary platen and a movable platen of a die casting machine for stopping the closing movement of a movable platen, the improvement comprising said safety bar comprising two parts, each part having at one end a connecting mechanism for operatively connecting said bar to one of said platens;
- and each part at its other end operatively connected to a cushioning mechanism to absorb the inertial forces generated by the movement of said movable platen as it is being stopped.
In a die casting machine having a from platen, a rear platen, a movable platen located between said front and rear platens, an actuator for moving said movable platen between open and closed positions;
- and a safety bar mechanism operatively connected between said movable platen and said rear platen for stopping the movement of said movable platen short of said closed position as it is moving toward closed position;
- the improvement comprising:
- a cushioning mechanism mounted on said one of movable platen and said rear platen to absorb the inertial forces generated by the movement of said movable platen toward said front platen as it is being stopped.
