Ultrasonic cleaning method for aluminum alloy die casting

Abstract

The invention relates to an ultrasonic cleaning method for an aluminum alloy die casting. The method uses ultrasonic cleaning equipment. The ultrasonic cleaning equipment comprises a cleaning frame, clamping units, a cleaning unit and ultrasonic transmitters. The clamping units are arranged on the inner walls of the left and right ends of the cleaning frame. The cleaning unit is arranged on the inner wall of the rear end of the cleaning frame. The ultrasonic transmitters are arranged on the inner wall of the lower end of the cleaning frame. The method adjusts the angle of a spray water gun anda movable spray water gun, so that the washing process of a runner is more comprehensive, the workload of ultrasonic cleaning is reduced, and the problem that the water flow can only be sprayed on afixed point on the outer surface of the aluminum alloy die casting during the washing process is solved. The method clamps and fixes the runner according to the structural characteristics of the runner, and drives the runner to flip, thereby improving the efficiency of washing and ultrasonic cleaning.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to an ultrasonic cleaning method for aluminum alloy die castings. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through 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. Die-casting parts have different names in different places, such as die-casting parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, copper die-casting parts, zinc die-casting parts, aluminum die-casting parts aluminum die-casting parts, aluminum die-casting parts Alloy ca...

AI Technical Summary

Problems solved by technology

[0003] The following problems often exist in the cleaning process of aluminum alloy die castings: 1. In the process of ultrasonic cleaning aluminum alloy die castings, the aluminum alloy die castings are often rinsed first, and the water flow can only be sprayed on the aluminum alloy die castings during the washing process. Fix the outer surface; 2. When the existing equipment is cleaning the runner, the runner is placed on the top of the filter net. The contact area between the runner and the filter net is relatively large, which affects the efficiency of ultrasonic cleaning. At the same time, it is placed on the filter net for cleaning , it is impossible to clamp and turn over the runner, thus reducing the effect of ultrasonic cleaning
