Abstract
Official abstract text for this publication.
The invention provides a die casting apparatus which pumps up molten metal from a molten metal holding furnace through an electromagnetic pump pipe provided with an electromagnetic pump, supplies the pumped-up molten metal to an injection sleeve through the molten metal supply pipe connected with the electromagnetic pump pipe, and a cavity of a die is charged with the molten metal by injecting the molten metal by using an injection tip. An upper end side of the electromagnetic pump pipe and an upper end side of the molten metal supply pipe are connected with each other. The upper end side of the electromagnetic pump pipe is inserted into the upper end side of the molten metal supply pipe, and extends inside the molten metal supply pipe.
First claim
Opening claim text (preview).
What is claimed is: 1. A die casting apparatus comprising: an electromagnetic pump pipe provided with an electromagnetic pump; and a molten metal supply pipe connected with the electromagnetic pump pipe, wherein molten metal is pumped up from a molten metal holding furnace through the electromagnetic pump pipe provided with the electromagnetic pump, the pumped-up molten metal is supplied to an injection sleeve through the molten metal supply pipe connected with the electromagnetic pump pipe, and a cavity of a die is charged with the pumped-up molten metal by injecting the molten metal by using an injection tip, an upper end side of the electromagnetic pump pipe and an upper end side of the molten metal supply pipe are connected with each other, and the upper end side of the electromagnetic pump pipe is inserted into the upper end side of the molten metal supply pipe, and extends inside the molten metal supply pipe. 2. The die casting apparatus according to claim 1 , wherein inside of piping from the electromagnetic pump pipe to the molten metal supply pipe is structured so as to be sealable. 3. The die casting apparatus according to claim 1 , wherein an opening and closing portion is provided on the upper end side of the molten metal supply pipe. 4. The die casting apparatus according to claim 1 , wherein a heater is provided on the upper end sides of the electromagnetic pump pipe and the molten metal supply pipe. 5. The die casting apparatus according to claim 1 , wherein an extended portion of the electromagnetic pump pipe extends to a part of the molten metal supply pipe, which is closer to a molten metal supply opening than an insertion portion of the molten metal supply pipe. 6. The die casting apparatus according to claim 1 , wherein the molten metal supply pipe extends downward continuously when the molten metal supply pipe extending towards the molten metal supply opening side, from a part of the molten metal supply pipe, in which an extended portion of the electromagnetic pump pipe extends, to a part of the molten metal supply pipe, which is inserted into the molten metal supply opening. 7. The die casting apparatus according to claim 1 , wherein the electromagnetic pump pipe extends upwardly to be inclined to a horizontal plane, and the molten metal supply pipe extends upwardly to be inclined to the horizontal plane. 8. The die casting apparatus according to claim 1 , wherein the upper end side of the electromagnetic pump pipe and the upper end side of the molten metal supply pipe are connected with each other orthogonally.
