Slag removing device for die casting machine

Abstract

The invention belongs to the field of devices for removing impurities from metal liquid in the casting industry, and in particular, discloses a slag removing device for a die casting machine. The device comprises a frame; the frame is rotationally connected with two first rotating shafts; the two first rotating shafts are fixedly connected with first paddles; sleeves are fixed on outer rings of the first rotating shafts; axes of the sleeves are parallel to axes of the first rotating shafts; a V-shaped frame is arranged between the two first rotating shafts; the two ends of the V-shaped frame are slidingly connected into the two sleeves; a lantern ring sleeves the connected place of the V-shaped frame; one side of the lantern ring is fixedly connected with a connecting rod, and the other side is fixedly connected with a slag removing net; the frame above the lantern ring is vertically and slidingly connected with a slide block; the slide block is hinged to one end of the connecting rod;and the frame is provided with a driving mechanism for driving the slide block to vertically slide on the frame. The device uses automatic mechanical slag removal for replacing manual slag removal, so that the production efficiency is improved, and the accident occurrence probability is reduced.

Description

technical field [0001] The invention relates to the field of devices for removing impurities in liquid metal in the foundry industry, in particular to a slag removal device for die-casting machines. Background technique [0002] Die-casting machine is a common equipment in the field of forming technology in the machinery industry. It is an industrial machine that hydraulically injects molten metal into a die-casting mold for cooling and forming under pressure, and obtains solid metal castings after the mold is opened. [0003] Among them, the quality of molten metal, that is, molten aluminum, has become the key to the quality of die castings, which directly affects the molding quality and internal microstructure of die castings, and determines its mechanical properties to a large extent. In industry, molten aluminum usually contains a large amount of gas and impurities. In order to remove gases and impurities in molten aluminum, slag remover and protective gas are often put ...

AI Technical Summary

Problems solved by technology

After the slag removal is completed, the excess slag remover and impurities in the aluminum liquid will float on the surface of the aluminum liquid. The current treatment method for the floating residue is to manually use the slag pick tool to manually remove the residue floating on the upper layer of the aluminum liquid. Slag removal, due to the high temperature of molten aluminum, safety accidents are likely to occur in the process of manual slag removal, and the efficiency of manual slag removal is low
