PURPOSE: To obtain a switch gear which can cope with a multi-kind and smal- quantity production, by a method wherein a rotary member is controlled by a guide groove and a guide rod so that the rotary member is not separated from a rail and a mold is divided, opened and closed by shifting a table accorrding to a rail by rotating the rotary member.
CONSTITUTION: A rotary member 5 is controlled so as to move only along a guide groove 3 without separating from a wall 4 by an action of a guide rod 11 and on the one hand, as the rail 4 is fixed to a side plate, the rotary member 5 is moved along the groove 3, according to which an opening and closing actions of a spindle 6, bearing 13, table 12 and top force 16 fixed to the table are performed. When the table 12 is shifted in company with the rotary member 5, a guide rod 14 on both ends of the table 12 is shifted also in company with the guide groove 3 and conditions of the top force 16 are varied. The side plate is divided into the upper and lower parts 2A, 2B, therefore, if a large number of the side plates which has interchangeability in an external form and fitting hole and only a mold action can be changed swiftly to arbitrary one by rearranging the side plates arbitrarily.
