Abstract
This apparatus, preferably applicable to a molding machine using the core change type dies, is capable of pushing out the inserted core from the mother mold, thereby facilitating the core extracting operation by the robots. A mother mold of a complementary die in the core change type dies is constituted by a main body and an intermediate plate which is disposed behind the main body and to be movable in both the forward and backward directions. A core fixing and releasing mechanism is provided on the intermediate plate. Furthermore, there is provided a push-out device disposed in a clearance formed between the main body and the intermediate plate when the intermediate plate is shifted rearward. The push-out device has its one surface abutting on a front surface of a core and its another surface abutting on a rear surface of the main body. The push-out device is attached to a distal end of an arm of a robot, combined with a molding machine, so that the push-out device is slidable in both the forward and backward directions and is urged rearward, if necessary.
