Changing device for the moulds of injecting moulding machines

摘要

Injection moulding machines, to which a robot 9 with gripper elements 13 for inserting and/or for removing and for feeding and conveying away the injection mouldings relative to the open mould which is in use is allocated, are equipped with a changing device for the moulds 5 in which the two mould halves 5a and 5b of the moulds 5 can be aligned between two opposing mounting plates 15a, 15b, which can be moved as desired towards one another for closing the mould 5 and away from one another for opening the latter, of a closing unit of the injection moulding machine and can be clamped in their aligned position. In order simultaneously with the change of the moulds 5 also to make possible an automatic change of the gripper elements 13 for the removal robot, each mould 5 has assigned to it independent gripper elements 13, adapted to the injection mouldings, for the removal robot. These gripper elements 13 have coupling means 17 for the exchangeable connection to a support arm 12 of the robot 9. At least one of the mould halves 5a and 5b of the moulds 5 is provided with mounts 18 for the releaseable engagement of the associated gripper elements to 13 to be decoupled from the support arm 12 of the robot 9. <IMAGE>
