There is provided an apparatus for taking out a molded product that facilitates setting of a user-set lower limit value while maintaining on-off control. A negative pressure control portion includes a determining portion for determining a pressure valve resumption time period that is used to resume a suctioning operation such that an inflection point does not become lower than a user-set lower limit value. The negative pressure control portion continuously performs an off operation, which is performed to keep a pressure valve closed until the pressure valve resumption time period elapses after the suctioning operation is stopped, and an on operation, which is performed to open the pressure valve and keep the pressure valve open until a negative pressure reaches a stable value or an upper limit set value, until suctioning of a molded product is canceled.

There are provided an apparatus for taking out a molded product that allows a physical amount such as the mass of the taking portion to be easily acquired with a relatively simple configuration. A posture reversing mechanism is provided between the elevating arm and the taking portion to change the 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 the length of the taking portion in the vertical direction is shorter than that in the unreversed state. A sensor detects vibration of the elevating arm. A mass estimating section estimates the mass of the taking portion on the basis of vibration of the elevating arm detected by the sensor when the taking portion is in the reversed state.
