ABSTRACT:
Apparatus for mounting a pair of die members so that one die member can move toward and away from the other die member. The apparatus includes a pair of spaced die shoes for mounting respective die members and an electromagnetic unit for moving one of the die shoes toward the other die shoe. The electromagnetic unit includes a coil mounted on one of the die shoes and an armature mounted on the other die shoe, the electromagnet and the armature being between the die shoes. The armature is aligned with and partially extends into a recess in the central portion of the coil so that, when current flows through the coil, the armature is attracted to the coil and moves the other die shoe toward the one die shoe. A bias structure biases the other die shoe away from the one die shoe. Such bias structure can take the form of an air cylinder or a spring.
