Correcting method of injection condition of die casting machine based on molten material supply

Abstract

In order to inject and fill the melt into the cavity of the mold, the amount of melt injected into the injection sleeve is measured with high accuracy to correct the injection conditions of the die casting machine. A die-casting machine with a casting spoon (4), which draws molten metal from a melting furnace; an injection sleeve (7), which is injected with molten metal drawn through the casting spoon (4); an injection plunger (8) that advances or retreats in an injection sleeve; an injection cylinder (9) that advances or retreats the injection plunger (8); the injection plunger (8) is advanced through the injection cylinder (9), thereby injecting and filling the metal melt contained in the injection sleeve into the cavity of the mold of the closed mold; the molten surface height (h) of the molten metal injected into the injection sleeve from the casting spoon (4) is measured by the molten surface detection sensor (10), and the molten metal supply amount of the molten metal is measuredby calculation to correct the injection conditions.

Description

technical field [0001] The present invention relates to a method of correcting injection conditions of a die casting machine for injecting and filling molten material supplied into a molten material supply chamber of an injection sleeve into a cavity of a mold by advancing an injection plunger. In particular, it relates to a method of correcting injection conditions of a die casting machine by measuring the amount of molten material actually injected into a molten material supply chamber of an injection sleeve when the molten material is injected and filled into a mold cavity at high speed. Background technique [0002] In conventional general die-casting machines, when the metal material melted by the melting furnace is picked up with a ladle per one shot, the drawn amount is controlled to a predetermined amount, and the drawn molten material is supplied to the injection sleeve The melt supply port of the barrel. Then, the molten metal is injected and filled into the cavit...

AI Technical Summary

Problems solved by technology

However, as mentioned above, even if the amount of molten material in the ladle is controlled, there is still a problem that the amount of molten material changes due to adhesion of the molten material to the ladle or spillage of the molten material from the ladle, etc.
