Technical field
The utility model belongs to machine casting technical field, and in particular to one kind casting ingate earthenware elbow structure.
Background technology
In the foundry production of casting, running gate system is the passage that molten metal enters casting mold die cavity, and ingate is gold
Belong to the final stage passage that liquid enters casting mold die cavity.Existing ingate has diversified forms, for it is complicated, size drop is big
Casting typically using earthenware overlap joint ingate, earthenware is overlapped on the end of ingate and is connected with casting mold die cavity.Pottery
Porcelain tube have the advantages that flexibility is high, sectional dimension precisely, will not sand washing, be overlapped with the ingate of earthenware with traditional sand mold
Running channel is compared, and is more suitable for casting complicated and that size drop is big.Traditional ingate earthenware is usually equal pipe knot
Structure, certain deficiency be present：First, traditional ingate earthenware and the cross-sectional area of casting mold die cavity junction are larger, special
It is not the outlet by the use of the earthenware being relatively large in diameter as ingate, is difficult often cutting, larger difficulty is caused to post processing polishing；
Secondly, some less earthenwares of casting sectional area can not overlap, in addition, molten metal flows through ingate when entering casting mold die cavity,
Molten metal washes away earthenware water outlet casting position for a long time, and it is too high to be easily caused the position local temperature, makes its position modulus
Increase, the defects of easily producing shrinkage porosite, shrinkage cavity, burning into sand for the small casting of sectional area or thin-section casting.
Utility model content
Purpose of utility model：The purpose of this utility model is to solve deficiency of the prior art, there is provided one kind passes through
Elbow transition is carried out using earthenware duct, the molten metal pressure of ingate delivery port position, increase casting cooling can be born significantly
When ingate area of dissipation, reduce the position modulus of ingate and casting mold die cavity junction, reduce the shrinkage porosite of casting, shrinkage cavity is inclined
To, Improving The Quality of Products, while use ceramic material substantially prolongs the casting ingate earthenware elbow structure of service life.
Technical scheme：A kind of casting ingate earthenware elbow structure described in the utility model, including the first pipeline, the
Two pipelines and connecting bending pipeline, first pipeline are connected as one with second pipe by connecting bending pipeline transition, and described
First pipeline, second pipe and connecting bending pipeline use integrated formed structure, the caliber of first pipeline and the described second pipe
The caliber in road is equal or unequal, first pipeline, and second pipe and connecting bending pipeline use ceramic structure, the elbow knot
One end of structure is used for the end for connecting ingate, and the other end is used to connect casting mold die cavity, the angular range of the connecting bending pipeline
It is 60-150 °.
Further, the thickness of first pipeline, second pipe and connecting bending pipeline is 1-6mm.
Further, the caliber ratio of first pipeline and the second pipe is 1：1-3.
Further, the length ratio of first pipeline and the second pipe is 1：1-3.
Further, first pipeline, the thickness between second pipe and connecting bending pipeline are equal or unequal.
Further, the cross section of first pipeline or second pipe is kidney ellipsoid or circle.
Beneficial effect：The utility model carries out elbow transition by using earthenware duct, can bear ingate water outlet significantly
The molten metal pressure of mouth position, the area of dissipation of ingate, reduces ingate and casting mold die cavity junction when increase casting cools down
Position modulus, reduce shrinkage porosite, the shrinkage cavity tendency of casting, Improving The Quality of Products, while substantially prolongs and make using ceramic material
Use the life-span.
Brief description of the drawings
Fig. 1 is the structural front view of the utility model one embodiment；
Fig. 2 is Fig. 1 sectional view.
Embodiment
The technical solution of the utility model is described in further detail with reference to specific embodiments and the drawings：
Embodiment 1
A kind of casting ingate earthenware elbow structure as depicted in figs. 1 and 2, including the first pipeline 1, second pipe 3
With connecting bending pipeline 2, first pipeline 1 is connected as one with second pipe 3 by the transition of connecting bending pipeline 2, and described
One pipeline 1, second pipe 3 and connecting bending pipeline 2 use integrated formed structure, the caliber of first pipeline 1 and described second
The caliber of pipeline 3 is equal, first pipeline 1, and second pipe 3 and connecting bending pipeline 2 use ceramic structure, the elbow structure
One end be used to connect the end of ingate, the other end is used to connect casting mold die cavity, and the angular range of the connecting bending pipeline 2 is
90 °, the cross section of the first pipeline 1 is circle, and the cross section of the second pipe 3 is also circle.
The caliber ratio of first pipeline 1 and the second pipe 3 is 1：1-3；First pipeline 1 and the described second pipe
The length ratio in road 3 is 1：1-3.The radiating effect of ingate is reduced and ensures in the molten metal pressure for ensureing ingate delivery port position
On the basis of fruit, the overlap joint needs of most of casting mold die cavities can be met.
The thickness of first pipeline 1, second pipe 3 and connecting bending pipeline 2 is 1-6mm, and first pipeline 1,
