Die-casting die for aluminum casting

Abstract

The invention relates to the field of industrial manufacturing, and specifically relates to a die-casting die for an aluminum casting. The die-casting die for the aluminum casting comprises a die-casting part, a dredge part, an exhaust part and a rotary heating part, wherein the die-casting part comprises a die-casting main body and a die-casting acceptor; the dredge part is arranged at a pipelinepart in the die-casting main body; a buffer ring, a first magnetic ring and a second magnetic ring are fixedly arranged to an inner ring of a pipe body of the dredge part in sequence from top to bottom; a flow guide block, a flow distribution block and a magnetic block are fixedly connected to the front part and the rear part of the inner ring of the pipe body of the dredge part in sequence fromtop to bottom; a thread shaft is in threaded connection to one side of an exhaust part body; chucks are movably connected to the two sides of the inner wall of the exhaust part body through movable shafts separately; and two gas flow adjustment clamps are clamped between the chucks. Through the arrangement for the exhaust part, in an actual process of pushing molten aluminum for die-casting, exhaust for the gasified gas in the device is facilitated, so that high-temperature liquid metal is enabled to make contact with air in the die to be gasified in an injection process, and dredge for accumulated gas in the device is facilitated.

Description

technical field [0001] The invention relates to the field of industrial manufacturing, in particular to an aluminum casting die-casting mold. Background technique [0002] Die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is: the molten metal is first filled into the cavity of the mold by low-speed or high-speed casting, The mold has a movable cavity surface, which is pressurized and forged with the cooling process of the molten metal, which not only eliminates the shrinkage cavity and shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state, but the existing aluminum Die casting molds also have the following problems: [0003] During the heating process of liquid metal, since some of them have been more or less solidified, the thrust of the transfer pump alone is not enough...

AI Technical Summary

Problems solved by technology

[0004] In the liquid metal pushing process, due to the high density, the fluid flow effect is not enough to forcefully push the injection die-casting operation;

[0005] During the injection molding process, the high-temperature liquid metal is in contact with the air inside the mold to vaporize it, resulting in internal gas accumulation. When the accumulated gas is discharged, it is not convenient to accurately adjust the displacement of the exhaust port.
