Description

technical field [0001] The invention relates to a feed pipe for anti-erosion of a die-casting barrel, which relates to a feed pipe structure for avoiding erosion of a die-casting barrel and belongs to the field of alloy manufacturing. In particular, it relates to a feed pipe structure capable of dividing the aluminum-magnesium alloy liquid layer by layer so that it can offset each other when the liquid is discharged, reduce the impact kinetic energy of the alloy liquid, and avoid excessive erosion of the deflector. Background technique [0002] At present, during the pressure casting process of aluminum-magnesium alloys, due to the high temperature of the alloy liquid and the large drop directly falling into the barrel through the trough, the high-temperature alloy liquid has relatively large kinetic energy.

Problems solved by technology

[0002] At present, during the pressure casting process of aluminum-magnesium alloys, due to the high temperature of the alloy liquid and the large drop directly falling into the barrel through the trough, the high-temperature alloy liquid has relatively large kinetic energy. When the alloy liquid falls When it reaches the bottom of the barrel, it will produce high-temperature and high-speed impact and erosion on the barrel, which will easily cause wear inside the barrel and affect its normal service life. The buffer discharge energy of high-temperature and high-speed alloy liquid reduces the erosion of the barrel, but the essence of this method is to transfer the erosion of the alloy liquid to the barrel to the splitter plate in a disguised form, and the splitter plate is subjected to greater erosion force , lower service life

[0003] The notification number CN110328350A discloses an anti-erosion device for a die-casting barrel, which includes a barrel and a guide hopper. The barrel is a horizontal cylindrical barrel with an arc-shaped cavity inside and a feeding The guide funnel is fixed on the feed inlet. The guide funnel is composed of a feed hopper, a fixed bracket and a guide splitter plate. The fixed brackets are arranged on both sides of the hopper, and the hopper is fixed in the feed inlet through the fixed bracket. The guide splitter plate is set in the feed hopper. The guide splitter plate used in the anti-erosion structure of the material barrel bears a large erosion force and has a low service life, so it needs to be replaced frequently
