The utility model discloses a sensor for injection mold, injection mold includes: fixed die plate (100), movable mould board (200) and die cavity (300), the sensor includes: sensor body (1), surface remove with die cavity (300) contact surface all is provided with the insulating layer outward, be used for with fixed mould assembly (110) constitute the two poles of the earth of test capacitor, the wiring (2), one end with sensor body (1) is connected, and its other end is connected with the power, is used for doing the test capacitor charges, and perhaps, its other end and computer link are used for doing the computer transmission the voltage signal of test capacitor in whole injection moulding cycle. The utility model discloses an in the shrinkage factor that the voltage signal that the sensor was monitored can reflect the speed of moulding plastics of the medium -sized intracavity of injection moulding cycle, the weight of moulding plastics, the solidification rate of moulding plastics, moulded plastics at l
