PURPOSE: An injection mold device equipped with a nozzle center-aligning tool is provided to prevent the bending deformation of a nozzle body by preventing the delivery of transverse deformation, which is generated by the thermal expansion of a manifold, between a connecting member and a retainer. CONSTITUTION: An injection mold device comprises a nozzle central alignment tool(40). The nozzle central alignment tool comprises a connecting member(41), a retainer(43), and a guide ring member(46). The guide ring member is combined in a nozzle body and is connected to the retainer which is coupled in the manifold(10). The center of outlet of a resin path(22) of the manifold copes with the center line of the nozzle body. The outer circumference of the guide ring member is supported with the inner wall of a nozzle body mounting hole(1a) of a fixed mold(1). The deformation of the nozzle body is prevented by absorbing the transverse transformation of the nozzle body between the retainer and the connecting member.
