Diecasting die

摘要

The invention relates to a diecasting die, in particular in a diecasting hot-runner system, wherein the diecasting die is provided in a feeding region for forming a plug of solidified molten material that interrupts a flow of the molten material and can be completely remelted. A diecasting die is provided according to the preamble of the invention that is suitable for different molten materials, in which a heating acts directly on the molten material with high power and largely without delay. Cooling is not required and the injection-molding method can be carried out at a high operating machine speed and under feeding conditions that can be monitored and reproduced well. A feeding region is provided comprising direct resistance heating that produces a melting heat and is in direct thermal contact with the molten material.

主权项

1. Diecasting die (7, 20, 30, 45, 50, 50′, 60, 60′, 60″, 86, 86′, 86″) for sprueless diecasting, in particular in a diecasting hot-runner system (1), wherein the diecasting die (7, 20, 30, 45, 50, 60, 60′, 60″, 86, 86′, 86″) provides a plug of solidified molten material (22) in a feeding region (8) to completely interrupt the flow of the molten material, characterised in that the feeding region (8) comprises a direct resistance heating that generates smelting heat and is in direct thermal contact with the molten material (22), wherein the diecasting die has a conducting die wall (55) that has a first polarity, and a conducting molten material (22) that has a second polarity.
