Die casting pouring device

Abstract

The invention discloses a die casting pouring device. The die casting pouring device comprises a funneled brick, fountain bricks, a fountain chassis connecting brick, a first deflecting brick, cross gate bricks, second deflecting bricks and gate tail bricks, wherein the interiors of the funneled brick, the fountain bricks, the fountain chassis connecting brick, the first deflecting brick, the cross gate bricks, the second deflecting bricks and the gate tail bricks communicate with one another in sequence to form a pouring passage; in addition, the die casting pouring device is further providedwith die bottom bricks; the die bottom bricks are arranged on the upper portions of the gate tail bricks; pouring holes are formed in the die bottom bricks and communicate with the pouring passage inthe gate tail bricks; and the included angle between the pouring holes and the horizontal direction is 10-60 degrees. Thus, the effect that the jet flow speed is decreased can be finally ensured during pouring, impact of jet flow on liquid levels is reduced, and the quality of steel ingots is improved.

Description

technical field [0001] The invention relates to the field of mold casting, in particular to a casting device for mold casting. Background technique [0002] Die casting is a traditional production process of molten steel solidification and forming. Due to its unique characteristics, it is still widely used in the production of large compression ratio and small batch products. In the mold casting process of killed steel, in order to ensure the quality of the steel ingot, the casting method is generally adopted, that is, the molten steel must first enter the middle injection pipe before entering the ingot mold, and reach the bottom of the ingot mold through the runner in the chassis. It is sprayed from the rising hole here, and then the molten steel solidifies in the ingot mould. In addition, after the molten steel has risen to a certain level, it is necessary to cover the surface of the molten steel with molding powder to achieve the purpose of isolating the air and reducing...

AI Technical Summary

Problems solved by technology

The disadvantage of this gating system is that the impact of the rising jet on the liquid steel surface is relatively large

When pouring a steel ingot with a large cross-section, due to the large surface area of ​​the liquid surface, the surface tension at the center is small, and the mold slag on the surface of the liquid surface is easily broken by the rising jet, resulting in the exposure of the molten steel to the air, resulting in the second generation of molten steel. Secondary oxidation and nitrogen absorption reduce the quality of steel ingots
