A multi-direction under-cut module for a mold is provided to make the under-cut module small by optionally operating one or both of first and second shape sliding cores with an operation unit. A multi-direction under-cut module for a mold comprises an operation unit(30) moving forward and backward, and having a guide pin(32) extended in a forward and backward direction, a slide penetration unit(34) inclined by a predetermined angle for the extension direction of the guide pin, and a guide slot(36) crossing at right angle with the slide penetration unit; a first shape slide core(20) provided with a pin moving hole(22) wherein the guide pin penetrates to be selectively communicated with the operation unit, and a core penetration hole(23) formed in the same slope angle with the slide penetration unit, and a first external appearance forming unit(21) forming a part of an external appearance of a product; and a second shape slide core(24) formed to perforate the slide penetration unit and the core penetration hole, provided with one end horizontally perforated by a hinge pin(28) positioned at the guide slot, and a second external appearance forming unit(26) forming a part of the product at the front. An inner diameter of the core penetration hole has a size wherein the second shape slide core moves, and an inner diameter of the slide penetration unit is relatively wider than an diameter of the second shape slide core whereby the second shape slide core communicates with the operation unit, and moves in a longitudinal direction of the core penetration hole and the slide penetration unit, simultaneously communicates with the operation unit and the first shape slide core, and moves in the same direction with the operation unit.
