1. An apparatus for taking out a molded product molded in a die of a molding machine, the apparatus being operable to transfer the molded product out of the molding machine and comprising:
a taking portion configured to take hold of the molded product molded in the die;
an arm provided to be capable of advancing and retracting in an opening direction of the die and moving up and down;
a posture reversing mechanism provided between the arm and the taking portion to change a direction of the taking portion between an unreversed state in which the taking portion is directed to be able to take hold of the molded product molded in the die, and a reversed state in which a length of the taking portion in a vertical direction is shorter than that in the unreversed state;
a sensor configured to detect vibration of the arm; and
a mass estimating section configured to estimate a mass of the taking portion on a basis of vibration of the arm detected by the sensor when the taking portion is in the reversed state.
