To eliminate the free running distance of an ejector rod.
An injection molding machine has a platen, a reversed table 39 attached reversibly to the platen, a mold main body attached to the table 39, a driving part for ejection, the ejector rod 17 which is moved forward/backward by driving the driving part, an ejector pin arranged forward/backward movably in the mold main body, and an extrusion member which is arranged forward/backward movably in the table 39, is advanced with the advance of the ejector rod 17, and advances the ejector pin. The extrusion member is arranged forward/backward movably in the table 39, is advanced with the advance of the ejector rod 17, and advances the ejector pin, so that the free running distance of the ejector rod 17 can be shortened by the length of the extrusion member.
