Abstract

The utility model discloses a kind of ingate earthenware, comprise earthenware body, earthenware body comprises the pipe portion and flat tube portion that are wholely set, pipe portion is connected with flat tube portion rounding off, the area of the endoporus in flat tube portion is greater than the area of the endoporus in pipe portion, pipe portion is for overlapping the end of ingate, and flat tube portion is for connecting casting mold die cavity.The utility model earthenware can reduce the molten metal pressure of ingate delivery port position, increase the area of dissipation of ingate during foundry goods cooling, reduce the position modulus of ingate and casting mold die cavity junction, reduce the shrinkage porosite of foundry goods, shrinkage cavity tendency, Improving The Quality of Products, alleviate polishing work difficulty, increase work efficiency.

Description

A kind of ingate earthenware
Technical field
The utility model relates to machine casting field, specifically a kind of ingate earthenware.
Background technology
In the foundry production of foundry goods, running gate system is the passage that molten metal enters casting mold die cavity, and ingate is the final stage passage that molten metal enters casting mold die cavity.Existing ingate has various ways, and generally adopt earthenware to overlap ingate for complex structure, foundry goods that size drop is large, earthenware is overlapped on the end of ingate and is connected with casting mold die cavity.Earthenware has that flexibility is high, sectional dimension precisely, can not the advantage such as sand washing, be overlapped with the ingate of earthenware compared with traditional sand mold ingate, be more suitable for complex structure and the large foundry goods of size drop.Traditional ingate earthenware is generally equal pipe structure, there is certain deficiency: first, the cross-sectional area of traditional ingate earthenware and casting mold die cavity junction is larger, particularly with the outlet of the larger earthenware of diameter as ingate, often be difficult to cutting, cause larger difficulty to post processing polishing; Secondly, the earthenware that some foundry goods sectional areas are less cannot overlap, in addition, metal liquid stream is when Inner running channel enters casting mold die cavity, molten metal washes away earthenware water outlet foundry goods position for a long time, easily cause this position local temperature too high, its position modulus is increased, and the foundry goods little for sectional area or thin-section casting easily produce the defects such as shrinkage porosite, shrinkage cavity, burning into sand.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, a kind of ingate earthenware is provided, the molten metal pressure of ingate delivery port position can be reduced, increase the area of dissipation of ingate during foundry goods cooling, reduce the position modulus of ingate and casting mold die cavity junction, reduce the shrinkage porosite of foundry goods, shrinkage cavity tendency, Improving The Quality of Products, alleviate polishing work difficulty, increase work efficiency.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ingate earthenware, comprise earthenware body, described earthenware body comprises the pipe portion and flat tube portion that are wholely set, described pipe portion is connected with described flat tube portion rounding off, the area of the endoporus in described flat tube portion is greater than the area of the endoporus in described pipe portion, described pipe portion is for overlapping the end of ingate, and described flat tube portion is for connecting casting mold die cavity.
The utility model ingate earthenware changes traditional ceramics tube shape, the shape of this earthenware is flat tube portion by pipe portion rounding off, the area of the endoporus in flat tube portion is greater than the area of the endoporus in pipe portion, the molten metal pressure of ingate delivery port position can be reduced, increase the area of dissipation of ingate during foundry goods cooling, reduce the position modulus of ingate and casting mold die cavity junction, reduce the shrinkage porosite of foundry goods, shrinkage cavity tendency, Improving The Quality of Products.Meanwhile, the width in flat tube portion is greater than height, is easy to overlap joint casting mold die cavity, and cuts removal after convenient casting, alleviate polishing work difficulty, increase work efficiency.
As preferably, the width in described flat tube portion is 3 ~ 5:1 with the ratio of height, ensureing that the molten metal pressure of ingate delivery port position reduces and guarantees on the basis of radiating effect of ingate, can meet the overlap joint needs of most of casting mold die cavity.
As preferably, the endoporus of the cross section in described pipe portion is circular, and the endoporus of the cross section in described flat tube portion is kidney ellipsoid.
As preferably, described earthenware body is for waiting wall thickness tube.
Compared with prior art, the utility model has the advantage of: ingate earthenware disclosed in the utility model, its shape is flat tube portion by pipe portion rounding off, the area of the endoporus in flat tube portion is greater than the area of the endoporus in pipe portion, the molten metal pressure of ingate delivery port position can be reduced, increase the area of dissipation of ingate during foundry goods cooling, reduce the position modulus of ingate and casting mold die cavity junction, reduce the shrinkage porosite of foundry goods, shrinkage cavity tendency, Improving The Quality of Products.Meanwhile, the width in flat tube portion is greater than height, cuts removal, alleviate polishing work difficulty, increase work efficiency after convenient casting.
Accompanying drawing explanation
Fig. 1 is the outside drawing of embodiment earthenware;
Fig. 2 is the upward view of embodiment earthenware;
Fig. 3 is A-A sectional view in Fig. 2;
Fig. 4 is design sketch after embodiment earthenware overlap joint uses.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
A kind of ingate earthenware as Figure 1-3, comprise earthenware body 1, this earthenware body 1 is for waiting wall thickness tube, earthenware body 1 comprises the pipe portion 11 and flat tube portion 12 that are wholely set, the endoporus 13 of the cross section in pipe portion 11 is circular, the endoporus 14 of the cross section in flat tube portion 12 is kidney ellipsoid, pipe portion 11 is connected with flat tube portion 12 rounding off, the width in flat tube portion 12 is 3 ~ 5:1 with the ratio of height, the area of the endoporus 14 in flat tube portion 12 is greater than the area of the endoporus 13 in pipe portion 11, pipe portion 11 is for overlapping the end of ingate 2, flat tube portion 12 is for connecting casting mold die cavity 3.
During use, pipe portion 11 is overlapped in the end of ingate 2, and flat tube portion 12 is connected on casting mold die cavity 3, thus make ingate 2, earthenware body 1 is communicated with successively with casting mold die cavity 3 (its design sketch is shown in Fig. 4), can carry out follow-up corresponding casting operation.
