An injection mold with a quick-change apparatus includes a top clamping plate, a cavity plate, a core plate, a core plate frame, an ejector mechanism and a bottom clamping plate. The core insert and the ejector mechanism are defined between the core plate and the core plate frame. A plurality of connecting rods are defined between the core insert and the ejector plates, one end of the connecting rod received in the passageway of the ejector plate, the other end of the connecting rod fixed in the cavity of the core insert to enable the ejector plate and the ejector ret plate to move up and down and connect with the connecting rod all long. So the ejector mechanism and the core insert are connected together, and can be changed together.
