Description

Semi-quantitative pouring cup for cast iron pouring

Technical Field

The utility model relates to the technical field of casting production, in particular to a semi-quantitative pouring cup for cast iron pouring.

Background

The pouring cup is used as an important component of the casting system and mainly used for receiving molten metal so as to facilitate casting; the direct impact of molten metal on the casting mould is reduced; the improvement of the hydrostatic pressure of the metal is mainly divided into two funnel-shaped pouring cups and pouring basins. When the iron casting is produced and poured, in order to ensure good performance and compact structure of the casting, a stable pouring process is needed when molten iron is poured, turbulence is not generated when the molten iron is filled, and air holes in the casting due to the fact that air is involved in the turbulence are avoided.

The pouring cup for pouring small and medium castings is usually square or round, and has the advantages of small volume, quick modeling and convenient replacement, but has the disadvantages that a pouring tool is required to have quite high skill level when the pouring cup is used for pouring, turbulent flow spraying phenomenon exists in the initial stage of pouring because molten iron is directly poured into a cavity, certain operation risk and potential safety hazard exist, and the quality of the castings is also influenced. Molten iron can also cause defects when entering a die cavity due to molten iron splashing caused by the molten iron striking the wall and the bottom of the pouring cup when the molten iron just begins to rush into the pouring cup. The molten iron can also be entrained with molten iron slag in the pouring process and directly enters the cavity along with the pouring gate to form casting slag inclusion, so that the quality of the casting is reduced.
