To facilitate the change of a chiller pin and to improve the efficiency of changing work.

In the chiller pin 1 being fit into a mold from the lower side and pushing up the mold after casting, the shaft 2 being inserted into the longitudinal hole for positioning a chiller set plate so as to vertically move, the chiller main body 4 having a larger size than the positioning longitudinal hole and being fixed to the upper part of the shaft 2 and fitting into the mold, and the stopper 6 being provided in the lower end part of the shaft 2 and operating so that the shaft 2 does not fall out of the positioning longitudinal hole when a pushing-up force is applied from the lower side are provided. By this way, the stopper is not operated at the time of pulling out/setting the chiller pin 1 of/to the chiller set plate in order to change, whereby the change of the chiller pin 1 is easily executed.
