ABSTRACT:
An injection-moulding system for an injection-moulding machine including a clamping assembly, a temperature-adjusting system, and an ejector. The clamping assembly comprises two horizontal beams for mounting on the platens of the injection-moulding machine and two vertical beams for crosswise mounting on the horizontal beams in multiple positions. The clamping assembly allows dies of various sizes to be clamped in one and the same machine. The temperature-adjusting system includes at least one cooling tube for detachable insertion into a blind hole formed in the die. The cooling tube is attached to coolant conduits which are permanently attached to a source of coolant. Dies can thereby be replaced quickly and easily without spilling any coolant. The ejector is adapted to eject the cooled product after opening of the die. The injector pins are in an inexpensive way glued to the ejector plate. Use of the injection-moulding system provides considerable cost savings over conventional devices.
