Abstract
The invention discloses a novel pouring system with a slag-collecting anti-crack function. The novel pouring system comprises a vertical runner injection pipe, a horizontal runner injection pipe, a flat-fan-shaped or rectangular inner runner for lateral inflow of a casting process, and a slag-collecting nest located in the upper part of the inner runner. According to the novel pouring system disclosed by the invention, the purity of molten steel in a cavity is improved, cracks in the periphery of a common bottom pouring inner-angle port are prevented, and the quality of a casting is improved. According to the novel pouring system disclosed by the invention, inclusions in the molten steel entering the cavity are effectively collected, thus the purity of the molten steel entering the cavity is improved; and the orientation of the molten steel entering the cavity is effectively controlled, the inclusions in the molten steel entering the cavity can be removed in cooperation with the design of a riser, and a double-slag-collecting effect is achieved. According to the novel pouring system disclosed by the invention, the inner runner is designed in the side surface of the casting and designed to be flat-shaped according to the wall thickness of the casting, thus a modulus formed at an inner gate can be effectively reduced, and in addition, cracks at the position of the inner gate can be effectively prevented through the design of R angles at the periphery of the inner gate.

Technical field
The invention mainly relates to the Foundry Production of sand casting steel-casting, for casting moulding system in, be that one kind has
The novel pouring system of collection slag buffering..
Background technology
Existing butterfly valve steel-casting and Engineering steel-casting are typically running channel, round ceramic Guan Zhi with round ceramic pipe merely
Connect and be connected with casting process bottom.Have the disadvantage that simple earthenware rising pouring water inlet cannot carry out collection slag to molten steel, and molten steel enters type
Chamber is to all the winds scattered, the irregular inflow of foreign substance in molten steel, it is impossible to discharged using corresponding measure；Round ceramic pipe directly with casting
Part connects, and impact of the molten steel to casting mold is larger, easily causes scab drop defect.In addition round ceramic pipe is directly and casting process
Bottom connects the excessive hot-die number increased at this and is also easy to produce crackle.
The content of the invention
It is an object of the invention to provide a kind of novel pouring system with collection slag anticracking, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, the present invention provides following technical scheme：
A kind of novel pouring system with collection slag pooling feature, includes sprue note pipe, cross gate rising pouring note pipe, casting
Part technique lateral inflow flat fan or rectangle ingate and the collection slag nest positioned at ingate top, described fan-shaped or rectangle are flat
The collection slag buffer structure collection slag nest of a column type is provided with above the position of flat ingate.
Further, the diameter of the collection slag buffer structure collection slag nest of described column type is 1.1 times that ceramics pour pipe diameter, high
Degree is 1.5 times of diameter.
Further, the center of described collection slag buffer structure collection slag nest is overlapped with the center of the circular cast gate of rising pouring.
Further, described collection slag buffer structure collection slag nest molding sand or ceramic depositing are made.
Further, described fan-shaped or flat rectangular ingate is connected with the round ceramic depositing of rising pouring.
Further, described fan-shaped or flat rectangular gate thickness should be 1/3rd of foundry goods junction thickness, with
The foundry goods junction gross area should be 2 times of the round ceramic depositing of rising pouring, should be the fillet knot of R10-R20 with foundry goods contact position
Structure.
The ingate of the present invention can adjust the individual of the size and cast gate of sector or rectangle cast gate according to the size of foundry goods
Number；The thickness of running channel is adjusted according to wall thickness at foundry goods water inlet；According to the Character adjustment cast gate of the structure of foundry goods and water inlet position
Direction.The adjustment by more than can be moved towards with effective control molten steel, coordinated Feeder Design effectively remove die cavity molten steel
Field trash.Collect the design of slag nest on ingate, according to the impulsive force for effectively reducing molten steel and can remove in molten steel
Field trash.The present invention Design of Gate is in the side of foundry goods and be platypelloid type, can have it is little reduction ingate at modulus, ingate
Crackle can be prevented ingate at for fillet with the foundry goods angle of cut and reduce impact of the molten steel to casting mold.
As further scheme of the invention：As further scheme of the invention：
Compared with prior art, the invention has the beneficial effects as follows：It is of the invention effectively to collect the folder in die cavity molten steel
Debris, improve the degree of purity into die cavity molten steel；What the present invention effectively had controls molten steel into the trend of die cavity, and cooperation emits
The design of mouth can be with the field trash in removal type intracavity molten steel, with dual collection slag effect.The Design of Gate of the present invention is in casting
The side of part and flat is designed to according to casting section thickness, can effectively reduce the modulus formed at ingate, add ingate
The design at surrounding R angle, can effectively prevent ingate position crackle.
