Abstract
A mechanism for opening and closing the mold of a battery grid casting machine which includes a reciprocable slide to which the movable mold half is directly connected for movement in unison therewith. A cam mounted on and movable with the slide is arranged to engage a cam follower within the first three-quarters of the slide stroke. The cam follower is operatively connected with knock-out pins on the stationary mold half to eject the cast grid during the opening stroke of the movable mold half.

In a battery grid casting machine which includes a stationary mold member and a movable mold member movable through a predetermined distance toward and away from the stationary mold member to open and close the mold, the combination comprising, a reciprocating mechanism connected to the movable mold member and movable through said predetermined distance to open and close the mold, said stationary mold member having a plurality of reciprocable grid knock-out pins thereon movable from a retracted to a projected position for ejecting a cast grid from the stationary mold member, means for actuating said pins and means operatively interconnecting said reciprocating mechanism with said actuating means and operable during the first half to three-quarters of the mold opening stroke to shift said pins to the fully projected position within said fraction of the mold opening stroke and thereby eject the grid.
In a battery grid casting machine which includes a stationary mold member and a movable mold member movable through a predetermined distance toward and away from the stationary mold member to open and close the mold, the combination comprising, a rectilinearly movable slide, means for moving said slide through a predetermined stroke from a retracted to an extended position, said movable mold member being connected with said slide for movement in unison therewith, said movable mold being shifted from the closed to the open position when the slide moves from the retracted to the extended position, a cam bodily movable with said slide, a plurality of grid knock-out pins on said stationary mold member projectable in the direction of separation of the mold members to eject a cast grid from the stationary mold member, a cam follower rockably supported on a fixed axis extending transversely of the direction of movement of said slide, said cam follower being located in the path of travel of said cam and being operatively connected with said grid knock-out pins to actuate the pins when the slide is shifted a predetermined distance in the mold opening direction.
