Die-casting machine

Abstract

The invention discloses a die-casting machine which comprises a rack, a first sliding block , a guide rail, foots, an electric cabinet, a first extrusion device, a first die body, a cohesion device, asecond extrusion device, a hopper, a feeding hole, a liquid inlet pipe, a washing device, a third extrusion device, a second die body, a second sliding block and a heating wire, wherein the foot arefixedly arranged on the lower surface of the bottom plate of the rack and is in contact with the ground; the washing device is arranged on the bottom plate of the rack; and the liquid inlet pipe is fixed on the side face of the rack and is connected with the washing device. The die-casting machine can heat alloy liquid in a pipeline in real time to keep the alloy liquid to be at the temperature most proper for casting and to prevent the problems about misrun and cold shut of a casting due to too low temperature of the alloy liquid. In addition, after casting, the washing device can wash the hopper and the pipeline to prevent the situation that impurities in the hopper are mixed with the alloy liquid to affect the casting quality when casting is carried out once more.

Description

technical field [0001] The invention relates to metal casting equipment, in particular to an aluminum alloy die-casting machine equipment. Background technique [0002] Nowadays, the automobile industry is developing in the direction of light weight, safety, energy saving, comfort and reducing environmental pollution, so the use of aluminum alloy parts in the automobile industry is increasing day by day. As one of the important components in the driving system of a car, the wheel hub not only bears the weight of the car, but also determines the appearance of the car. At present, under the general direction of automobile lightweight, aluminum alloy wheels are gradually replacing traditional steel wheels in modern automobile manufacturing and are widely used. [0003] Most of the existing aluminum alloy die-casting machines are hot chamber die-casting machines. In order to ensure the quality of the casting, it is necessary to ensure that the molten metal in the pipeline has g...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing aluminum alloy die-casting machines are hot chamber die-casting machines. In order to ensure the quality of the casting, it is necessary to ensure that the molten metal in the pipeline has good fluidity. However, the hot-chamber die-casting machines currently in use cannot process the molten metal in the pipeline at any time. Heating, it is easy to cause the problem of poor casting quality caused by the low temperature of the molten metal flowing into the mold

In addition, after the casting is completed, it is also very necessary to clean the hopper containing the molten metal, otherwise impurities mixed into the molten metal will affect the performance of the casting. However, most die-casting machines currently do not have a hopper cleaning device
