Abstract
An injection-molding machine whose mold-carrying plates are provided with quick-release locking devices for engagement with adapter plates on respective halves on the mold, also has at least one of the plates provided with a horizontal transverse guide for the mold whereby the mold can be inserted laterally and removed laterally. A carriage is displaceable along the machine and has roller conveyors and a device for drawing a mold from the machine onto the roller conveyor or pushing a mold from a roller conveyor onto the machine.
Claims20
A rapid mold-change system for an injection-molding machine installation having a pair of mold-carrying plates at least one of which is movable relative to the other horizontally in an injection-molding machine in a mold opening and mold closing direction, said system comprising:
- a horizontal guide extending perpendicular to said direction in a horizontal mold replacement direction on at least one of said mold-carrying plates;
- a mold engageable in said guide and shiftable in said mold replacement direction into and out of said guide, said mold having a pair of mold halves respectively engageable with said mold-carrying plates;
- locking means on said mold-carrying plates for retaining the respective mold halves thereon;
- a horizontal fixed rail extending in said mold opening and closing direction horizontally laterally alongside said machine, and
- a mold replacement mechanism including:
- a carriage riding on said rail and displaceable in said mold opening and mold closing direction alongside said machine,
- a transverse transport on said carriage alignable with said guide by movement of said carriage along said rail, and
- mold transfer means on said carriage displaceable in said mold replacement direction on said carriage for retracting a mold horizontally from said guide on said transverse transport and for displacing a mold horizontally on said transverse transport into said guide.
