The invention discloses a split sensor in an injection molding die, and the injection molding die. The split sensor comprises: a sensor main body (1) penetrating through a movable die core and formingtwo electrodes of a detection capacitor together with a fixed die core, and a sensing signal filtering and amplifying box (2) used for filtering and amplifying a capacitance signal acquired by the sensor main body (1). The split sensor can obtain the state of a melt in a die cavity according to the change of the capacitance signal of the detection capacitor in the whole injection molding process,the detected melt state information is continuous and abundant, and the sensor main body is in direct contact with the sensing signal filtering and amplifying box to make the capacitance signal directly input to the sensing signal filtering and amplifying box in a zero distance manner from the sensor main body, so the precision, the sensitivity and the stability of the sensing signal of the splitsensor are improved; and a
