Abstract

The utility model relates to a uniformly and quickly mold-filling pouring system which comprises a transverse water port, a straight water port and a flat inner water port, wherein the flat inner water port is connected with the transverse water port; the straight water port is connected with the transverse water port; the transverse water port has an annular structure; the diameter of the straight water port is larger than the diameter of the transverse water port; and the diameter of the transverse water port is larger than the diameter of the flat inner water port. The uniformly and quickly mold-filling gating system has the advantages that liquid alloy is smoothly filled in a cast mold without impacting the mold wall or the mold core, vortex flow and splash do not occur, no gas is drawn in, and the system is beneficial to discharging gas and other gas out of the mold, and controlling the pouring time and the pouring speed, to obtain an integrally casted bogie cast.

Description

A kind of running gate system of evenly filling type fast

Technical field

The utility model relates to a kind of running gate system of evenly filling type fast, is particularly useful for the cast of the heavy foundry goods of thin-walled.

Background technology

In the casting process of foundry goods, whether molten steel rises is suitable, also is one of important element that obtains premium casting, in casting process, should make suitable molten steel flow evenly and promptly fill with die cavity.If the fruit rate of climb is slow excessively, the sand mold upper face can be subjected to the intense radiation heat effect of molten steel for a long time and come off, and causes sand buckle, defectives such as burnt-in sand and sand holes; Also easily cause Chong sand and hot-spot at the position that molten steel is flowed through for a long time, foundry goods is cracked; In this external casting process, molten steel surface will form oxide film, can make foundry goods form pore, wrinkle, and defectives such as interlayer, this is more obvious on alloy-steel casting.If the molten steel rises excessive velocities can make foundry goods produce pore because being involved in gas again, concerning heavy castings, die cavity and top box can destroy because being subjected to greater impact power.

Summary of the invention

For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of running gate system of evenly filling type fast, makes liquid alloy steadily be full of casting mold, is beneficial to outside the air in the die cavity and other gas discharge types.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of running gate system of evenly filling type fast comprises the horizontal mouth of a river, peg gate, flat inner nozzle, and flat inner nozzle is connected with the horizontal mouth of a river, and the peg gate is connected with the horizontal mouth of a river, and the described horizontal mouth of a river is loop configuration; Described peg gate diameter is greater than horizontal mouth of a river diameter, and described horizontal mouth of a river diameter is greater than flat inner nozzle diameter.

Compared with prior art, the beneficial effects of the utility model are:

Make liquid alloy steadily be full of casting mold, impingement wall and core do not produce eddy current and splash, non-involvement gas, and be beneficial to outside the air in the die cavity and other gas discharge types, the control duration of pouring and poring rate obtain clear-cut, complete monoblock cast bogie foundry goods.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Among the figure: 3-peg gate, the horizontal mouth of a river of the flat inner nozzle 2-of 1-.

The specific embodiment

Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.

See Fig. 1, a kind of running gate system of evenly filling type fast comprises the horizontal mouth of a river 2, peg gate 3, flat inner nozzle 1, and flat inner nozzle 1 is connected with the horizontal mouth of a river 2, and peg gate 3 is connected with the horizontal mouth of a river 2, and the described horizontal mouth of a river 2 is loop configuration; Described peg gate 3 diameters are greater than the horizontal mouth of a river 2 diameters, and the described horizontal mouth of a river 2 diameters are greater than flat inner nozzle 1 diameter.

Embodiment:

Foundry goods adopts twice φ 120mm peg gate 3, the horizontal mouth of a river 2 of φ 100mm annular, the flat inner nozzle 1 of 21 road φ 60mm, flat inner nozzle 1 is connected with the horizontal mouth of a river 2 of loop configuration, peg gate 3 is connected with the horizontal mouth of a river 2 of loop configuration, casting pouring adopts the ladle of two φ, 90 bag eyes to pour into a mould, and two bag eyes flow cast, about 50 seconds left and right sides casting completes simultaneously entirely when cast.

The utility model makes liquid alloy steadily be full of casting mold, and impingement wall and core do not produce eddy current and splash, non-involvement gas, and be beneficial to outside the air in the die cavity and other gas discharge types, and stop that field trash enters die cavity; Regulate casting mold and the foundry goods each several part temperature difference, control the order of solidifying of foundry goods; Not hindering the contraction of foundry goods, reduce the distortion of foundry goods and open to attack and be inclined to certain feeding effect, mainly is supply operative liquid contraction before being solidified by running channel.

Claims

1. a running gate system of evenly filling type fast is characterized in that comprise the horizontal mouth of a river, peg gate, flat inner nozzle, flat inner nozzle is connected with the horizontal mouth of a river, and the peg gate is connected with the horizontal mouth of a river, and the described horizontal mouth of a river is loop configuration; Described peg gate diameter is greater than horizontal mouth of a river diameter, and described horizontal mouth of a river diameter is greater than flat inner nozzle diameter.
