ABSTRACT:
A device for separating and closing a split mold that comprises a base, a stationary platen, and a movable platen extending upward from the base and oriented to oppose each other, electromagnets, a hydraulic cylinder, and a control panel. The movable platen is capable of movement toward and away from the stationary platen by the hydraulic cylinder. The stationary platen has the electromagnets mounted thereon and the movable platen has the electromagnets mounted thereon. In the use of the device, the mold is positioned upon the base such that the first half is positioned against the stationary platen. The movable platen is moved against the second half and the electromagnets are activated. The movable platen is then moved away from the stationary platen, and the mold halves are held against their respective platens by the attractive forces of the electromagnets. Mold halves are thus separated by the movement of the platen away from the stationary platen in activation of the electromagnets.
