<p>The present invention relates to an apparatus for quickly heating or cooling an injection mold to the predetermined temperature. The apparatus comprises a plurality of heater-mounting holes (22), a plurality of electric heater cartridges (30) inserted into the heater-mounting hole (22), a fluid supply passage (40), and a heating/cooling fluid passage (50), in a mold block (20). According to the present invention, it is possible to prevent defects on the molded part due to temperature differential and to shorten a cycle time of the injection molding process.</p> |
