Abstract

The utility model relates to a vertical pouring gate, which comprises two sprues perpendicular to each other. The cross sectional area of the sprue in the vertical direction gradually decreases from top to bottom, and the cross section of the vertical sprue is trapezoidal. The utility model has the beneficial effects that the vertical pouring gate breaks through the traditional idea and improves the shape of the sprue, that is, the original straight sprue is transformed into the one with larger upper part and smaller lower part and certain inclination, so that the sprue can be instantly filled with molten iron flowing therethrough, and such impurities as dregs, gases, sands and the like which are lighter than the molten iron can float at the upper part of the sprue, thereby achieving good surface quality of cast products.

Description

Vertical running channel

Technical field

The utility model is the sprue structural improvement that the vertical mo(u)lding line of foundry industry uses.

Background technology

See also shown in Figure 1A-C, be the structure of existing vertical running channel.The sprue 2 that at present vertical mo(u)lding line uses leads directly to, and change area and realize with fault trough 1, bits like this, sand is involved in easily, has influenced the surface quality of foundry goods.And the waste molten iron has reduced the product yield of foundry goods.

The utility model content

The technical problem that the utility model solved is to provide a kind of skimming that is beneficial to, and prevents that gas etc. is involved in the new vertical running channel of subordinate's running gate system.

The technical solution of the utility model is: a kind of vertical running channel, comprise orthogonal sprue, and the sprue of vertical direction cross-sectional area from top to bottom reduces gradually.The cross section of sprue is trapezoidal.

The beneficial effects of the utility model are: the thinking of breaking the normal procedure, improved the shape of sprue, by original straight-through be improved to up big and down small, has certain gradient, area is calculated as follows: the large tracts of land place is identical with original calculating, press row's foundry goods and calculate at the small size place, be communicated with then, sprue has certain gradient like this, when molten iron is flowed through sprue, and instantaneous being full of, help bits, the impurity that gas, sand etc. are lighter than molten iron floats over the top of running channel, thereby obtains the good foundry goods of surface quality.

The specific embodiment

Shown in Fig. 2 A-C, a kind of vertical running channel of the utility model comprises orthogonal sprue, and wherein, sprue 3 cross-sectional area from top to bottom of vertical direction reduces gradually, and the cross section of this sprue is trapezoidal.

Adopt said structure, improved the shape of sprue 3, by original straight-through be improved to up big and down small, have certain gradient, area is calculated as follows: the large tracts of land place is identical with original calculating, and press row's foundry goods and calculates at the small size place, be communicated with then, sprue has certain gradient like this, when molten iron is flowed through sprue, and instantaneous being full of, help bits, the impurity that gas, sand etc. are lighter than molten iron floats over the top of running channel, thereby obtains the good foundry goods of surface quality.

As mentioned above, the utility model is novel, and is simple for structure, easy to use, is easy to make.Therefore the utility model provides a kind of vertical running channel, so, offer the application of utility model patent in accordance with the law; Yet, shown in the implementation and accompanying drawing that the utility model is above, be one of the utility model preferred embodiment, be not to limit to the utility model with this, be with, such as with approximate, identical person such as structure of the present utility model, device, feature, all should belong to of the present utility model founding within purpose and the claim.

Claims

1, a kind of vertical running channel comprises orthogonal sprue, it is characterized in that, the sprue of vertical direction cross-sectional area from top to bottom reduces gradually.

2, vertical running channel as claimed in claim 1 is characterized in that, the cross section of sprue is trapezoidal.
