Abstract

The molten metal supply device for a die-casting machine has a ladle equipped with a storing section which stores molten metal and a conveying device which conveys the ladle to a given supply position of the sleeve and tilts the ladle so that the molten metal drawn into the ladle is poured into the sleeve. The molten metal is poured into the sleeve while the position of the tip of the ladle lip against the sleeve is varied according to variation in the posture of the ladle.

Description

technical field [0001] The invention relates to a melt supply device of a die casting machine. Background technique [0002] In a die casting machine, after a molten metal is supplied to a sleeve, casting is performed by injecting the molten metal into a cavity of a mold from a plunger that injects the molten metal. As a molten metal supply device for supplying molten metal to a sleeve, for example, a ladle is known. [0003] The melt supply device uses a ladle to extract the molten metal in the molten metal furnace, and after the ladle is transported to the sleeve by the conveying device, the ladle is tilted around the specified rotating shaft to inject the molten metal into the sleeve. [0004] However, in the melt supply device using the above-mentioned ladle, for example, a rotating shaft is provided at the tip of the spout of the ladle, and the ladle is tilted by driving the rotating shaft with a chain. For this reason, the molten metal is poured at a substantially fi...
