PROBLEM TO BE SOLVED: To provide a stack mold which is simple in attachment/detachment, has a hot sprue which is applicable alternately to molds having cavities of substantially the same shape, and is small in load during mold opening/closing. SOLUTION: In the stack mold in which a fixed side template 12, a movable side template 14, and an intermediate template 13 are provided, during mold clamping, cavities 15 of a shape corresponding to a molding to be molded are formed independently between the templates 12 and 13 and between the templates 13 and 14 respectively, in the fixed side template 12, a communication hole 121 is formed at a non-overlapping position when the cavities 15 and 15 are projected on a surface crossing the moving direction of the mold perpendicularly, the hot sprue 1 is inserted freely attachably/detachably into the hole 121, one end of the hot sprue 1 is connected to a nozzle touch fitted to a fixed side mounting plate 122, and the other end of the hot sprue 1 is connected to a manifold 16 fitted to the intermediate template 13.
