Description
Technical field
The present invention relates to casting pouring apparatus field, more particularly to a kind of built-in type gate system.
Background technology
As railway freight-car is towards the development trend of high-speed overload, the important component of bolster, side frame as bogie,
Also improve corresponding manufacturer's standard.In existing bolster, side frame green-sand casting technique, the sprue cup for accepting molten steel is by setting
The cast gate sand set support that fat sand makes is fixed, and with reference to shown in Fig. 1 and Fig. 2, existing gate system includes sandbox 100, cast gate sand
Set 200, cast earthen-ware pipe 300 and sprue cup 400, it is had the disadvantages that in use at the scene:
1., sand set manufactured using resin sand, during cast after high-temperature baking, resin decomposition, cause sand mold defeated and dispersed, intensity drop
It is low, recycle difficult, cost height.
2., cast when sandbox often occur case band out-of-flatness, cause sand set place it is unstable, sprue cup cannot be guaranteed and pour
Note earthen-ware pipe is brought into close contact.The regular pouring defect for bottom of a cup badly bleeding occur, cause floating sand to enter casting die cavity, reduce product matter
Amount, molten steel utilization rate is reduced, while add the cleaning work amount of sandbox.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of built-in type gate system, which solve traditional cast gate system
The problem of molding sand of uniting is defeated and dispersed serious, production cost is high, the quality of production is low low with molten steel utilization rate, and propose a bit improvedly
Side.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of built-in type gate system, including cast earthen-ware pipe and sprue cup in sandbox, sandbox, it is located on the sandbox
Pour into a mould and be provided with accommodating groove at the port of earthen-ware pipe, the accommodating groove is made up of upper and lower two parts, and its upper part presents circle narrow under width
Bench-type, its underpart are in cylindrical type, and the sprue cup is positioned in accommodating groove, and the minimum diameter of the accommodating groove upper part is big
In sprue cup minimum diameter, less than sprue cup maximum gauge, the maximum gauge of the accommodating groove upper part is also greater than sprue cup most
Minor diameter, less than sprue cup maximum gauge.
Further improvement is that the angle of inclination of the round platform hypotenuse of the accommodating groove upper part and the hypotenuse of the sprue cup
It is identical.
Further improvement is that the hypotenuse lower end of the sprue cup is made up of outer ring and inner ring, the cast earthen-ware pipe is inserted in
Between outer ring and inner ring, the positioning to sprue cup is formd.
Further improvement is that in the outside of the outer ring formed with sand catcher.
The beneficial effects of the invention are as follows：
1) design of accommodating groove ensures that sprue cup can be fastened, and ensures not tilt during cast, completely solves bottom of a cup race
The phenomenon of steel, and meet the complicated use condition in scene, it is durable in use, it is unlikely to deform；
2) outer ring lower portion forms sand catcher, collects the floating sand of external mold in the course of the work, is not to enter in die cavity, protects
Demonstrate,prove the degree of purity of molten steel；
3) cast earthen-ware pipe is inserted between outer ring and inner ring, forms the positioning to sprue cup, when being further ensured that cast
It is stable, and ensure that the quality of cast product；
4) casting technique after improving eliminates the use of cast gate sand set, reduces production cost, mitigates whole system dress
The weight put, execute-in-place are light simple.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
With reference to shown in Fig. 3 and Fig. 4, a kind of cast earthen-ware pipe 2 in built-in type gate system, including sandbox 1, sandbox 1 and
Sprue cup 3, accommodating groove 4 is provided with the port of cast earthen-ware pipe 2 on sandbox 1, the accommodating groove 4 is made up of upper and lower two parts,
Its upper part presents circular platform type narrow under width, and its underpart is in cylindrical type, and sprue cup 3 is positioned in accommodating groove 4, and accommodating groove 4
The minimum diameter of upper part is more than the minimum diameter of sprue cup 3, less than the maximum gauge of sprue cup 3, and the maximum of the upper part of accommodating groove 4 is directly
Footpath also greater than the minimum diameter of sprue cup 3, less than the maximum gauge of sprue cup 3.The purpose so designed is to ensure that sprue cup 3 is placed
In accommodating groove 4, some can be higher than the plane of sandbox 1, and some is so advantageous to casting process in accommodating groove 4.
As preferred case, the round platform hypotenuse of the upper part of accommodating groove 4 is identical with the angle of inclination of the hypotenuse of sprue cup 3, this
