<P>PROBLEM TO BE SOLVED: To provide an injection mold which is made compact in size as a whole, and has simple structure. <P>SOLUTION: A first plate 44 of a movable mold 12 includes: a cam member 54 making a first slide core 24 move diametrically inward; a drive plate 108 driven by a driving mechanism provided in the injection molding machine; and a finger pin 120 supported by the drive plate 108. A second slide core 26 includes a guide hole 36 into which a part of the finger pin 120 is freely movably inserted. When the drive plate 108 moves in the mold clamping direction with respect to a third plate 48 by the driving mechanism, the second slide core 26 moves diametrically inward. <P>COPYRIGHT: (C)2012,JPO&INPIT |
