Aluminum alloy die-casting process capable of improving yield

Abstract

The invention discloses an aluminum alloy die-casting process capable of improving the yield. The aluminum alloy die-casting process comprises the following steps that S01, aluminum alloy raw materials are put into smelting equipment to be heated and melted; s02, the aluminum alloy solution is subjected to refining and impurity removal treatment; s03, a die-casting die is preheated; s04, high-purity aluminum alloy melt is injected into a die-casting die through a die-casting machine, and injection parameters of the aluminum alloy melt are dynamically adjusted; s05, keeping the constant temperature of the die-casting die for a period of time, and gradually cooling the die-casting die; s06, the aluminum alloy die casting is put into the cleaning mixed liquid to be cleaned; and S07, the aluminum alloy die casting is subjected to surface treatment in a combined mode. According to the aluminum alloy die-casting process disclosed by the invention, the aluminum alloy melt die-casting injection parameters are dynamically adjusted, so that the state of the die-casting fitting in the die-casting die can be dynamically adjusted, the pressing quality of the aluminum alloy die-casting fitting is effectively improved, and the yield of the aluminum alloy die-casting fitting is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of die casting processing, in particular to an aluminum alloy die casting process for improving yield. Background technique [0002] Die-casting is a kind of pressure-casting parts. It is a pressure-casting mechanical die-casting machine equipped with a casting mold. The metal such as copper, zinc, aluminum or aluminum alloy heated to a liquid state is poured into the feeding port of the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings, aluminum alloy die casting products are mainly used in electronics, automobiles, motors, home appliances and some communications Some high-performance, high-precision, high-toughness high-quality aluminum alloy products are also used in industries with relatively high requirements such as large aircraft and ships. The main use is still on the pa...

Problems solved by technology

[0003] In the existing aluminum alloy die-casting process, during the die-casting process, the state of introducing the aluminum alloy melt into the die-casting mold is relatively fixed, and it cannot be adjusted adaptively according to the amount of melt in the actual die-casting mold, resulting in poor die-casting quality of aluminum alloy die-casting parts. Insufficient, the yield rate is not high
