METHOD FOR OPERATING HOT CHAMBER DIE CASTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/091532
Kind Code:
A1
Abstract:
The present invention is a method for operating a hot chamber die casting machine that, in addition to not generating blow holes in the injection molding, is capable of injection molding in a short time and has excellent durability and with which the size of the space can be set freely. The method is configured so that: injection molding is performed by moving an injection plunger (7) to an injection completion position; the injection plunger (7) is then moved to a molten metal supply position and after waiting for a set period at the molten metal supply position, is moved to a set position to form a continuous space (10) between a nozzle (8) and a molten metal path (6); subsequently, the injection plunger (7) is moved to a filling completion position to fill molten metal in the space (10); after opening the mold (9) and removing the injection molding (11), the injection plunger (7) is moved to the injection molding start position to form a space (10) of a set size; and the mold is closed in this state and the injection plunger (7) is moved to the injection completion position.
