    • A nozzle hole sealing device for an injection nozzle capable of blocking a hole at the tip of a nozzle by using a robot in purging an injection molding machine. The nozzle hole sealing device includes a tool changer for connecting the nozzle hole sealing device to a wrist of the robot and a nozzle sealing body for sealing a nozzle hole by contacting the nozzle tip of the injection molding machine, thereby composing a nozzle sealing robot tool as a whole. A chuck mechanism for keeping a nozzle tip in contact with the nozzle sealing body, a heat reserving heater for a nozzle tip contact portion, and a resin passage ranging from the nozzle tip contact portion to a purged resin discharge surface including a constant pressure open value disposed in the middle of the passage may be further included.

    • 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.
