Abstract
The present invention relates to a kind of cup, especially a kind of filtering type cup is related to, it comprises the uncovered cup that a top holds molten iron, bottom is sand mold, sand mold side is provided with the sprue communicated with molten iron, sprue bottom is connected with the cross gate be parallel to each other successively, the end of undermost cross gate is connected with the afterbody sprue corresponding with above-mentioned sprue communicated with foundry goods, places screen pack between the above-mentioned cross gate be parallel to each other; Structure of the present invention is unique, catharsis can be played to the liquid metal in heavy castings casting process thus reduce slag inclusion, inclusion defect generation, reduce costs, improve the quality of products.
Description
Technical field
The present invention relates to a kind of cup, especially relate to a kind of filtering type cup.
Background technology
Inclusion defect is the one of the main reasons that heavy castings produce defective work, and inclusion defect causes a large amount of quality, cost, efficiency in Foundry Production.The method of this kind of defect of current solution places screen pack at the choked flow section of running gate system, utilizes the slag in the cellular structure filtration molten iron of screen pack.But some products cannot arrange screen pack by the restriction of following condition in running gate system: 1) sandbox, template size are little, without the useful space etc.; 2) particularity of process program, shape of product, can cause screen pack cannot add in technological design; 3) because large-tonnage foundry goods does not have enough positions to put screen pack; This just causes the slag inclusion problem of some products very serious, and filtering technique cannot use in some heavy castings, causes the product of inferior quality thus.In addition, some products due to the section ratio between sprue, cross gate, ingate improper, cause the influent stream excessive velocities of molten iron in die cavity, thus there is rollover phenomenon in molten iron in die cavity, produce a large amount of secondary slag, the relatively large sand mold that causes of the too fast percussion of influent stream speed to casting mold, core is broken, and burning into sand defect appears in foundry goods.
So far, the device of above-mentioned defect is not also overcome.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure unique, catharsis can be played to the liquid metal in heavy castings casting process thus reduce slag inclusion, the generation of inclusion defect, a kind of filtering type cup of reducing costs, improving the quality of products.
In order to realize goal of the invention, the present invention realizes in the following way:
A kind of filtering type cup, it is characterized in that: the uncovered cup that it comprises a top accommodation molten iron, bottom is sand mold, sand mold side is provided with the sprue communicated with molten iron, sprue bottom is connected with the cross gate be parallel to each other successively, the end of undermost cross gate is connected with the afterbody sprue corresponding with above-mentioned sprue communicated with foundry goods, places screen pack between the above-mentioned cross gate be parallel to each other;
The described cross gate be parallel to each other is two;
Described cup cross sectional shape is rectangular shape, and it is large volume structure that cup top holds molten iron, and the sand mold of bottom is entity structure;
Described screen pack is honeycomb fashion screen pack;
The weight of described screen pack is 1Kg-290Kg, and use one piece of screen pack, screen pack area of section is 80mm-150mm*80mm-150mm;
When the weight of described molten iron is the X times of 250Kg-290 Kg, described screen pack is then X.
The present invention has following effect:
1) structure is unique: cup cross sectional shape provided by the invention is rectangular shape, and cup top is large volume structure, for holding enough molten iron; Bottom is entity structure, and the centre of its underpart is provided with cross gate, and cross gate is divided into two-layer up and down, places screen pack in the middle of two-layer cross gate; One end of cup upper and lower cross gate connects with sprue, and the cross gate other end is also connected with sprue with the bottom of cup.According to the screen pack quantity that the Weight computation of casting of molten metal needs, according to number size and the arrangement of screen pack quantitative design overlap joint running channel.One piece of gate core is set in pouring basin sand mold, screen pack is arranged wherein, and back-up sand groove is set in the both sides of fuse, in case fuse hikes up under iron buoyancy of water.Molten metal after watering water inlet basin all by screen pack play purification, flow velocity and temperature adjustment effect.
2) generation of slag inclusion, inclusion defect is reduced: before cup molten iron provided by the invention is poured into die cavity, operator can take off Slag treatment to the primary slag floating to molten iron surface, but have a large amount of bits not remove totally, in addition, the impurity not partly fully being suspended to surface also can be stayed in molten iron.These bits do not removed can pour into pouring basin with casting ladle, and after the screen pack placed between two XX below pouring basin carries out filtration treatment to molten iron, molten iron is full of die cavity along running gate system again; Screen pack quantity in filtering type cup, not by the restriction of template, sandbox size, also not by the impact of shape of product, process program, also not by the restriction of poured weights, has stronger applicability; Filtering type pouring basin effectively reduces primary slag, alleviates secondary dreg defect, adjusts flow velocity, has obvious effect for the dreg defect solving foundry goods.
3) the influent stream speed of molten iron is cushioned, reduce turbulent flow, avoid sand washing: filtering type cup provided by the invention is owing to being provided with two-layer cross gate in bottom, and place honeycomb fashion screen pack in the middle part of two-layer cross gate, this design feature has very large cushioning effect to molten iron, both decreased the secondary slag that molten iron produces because of turbulent flow rolling, again reduced flow velocity, and avoided molten iron and stronger impulsive force is produced to sand mold.
4) reduce costs: the present invention adopts filtering type pouring basin to reduce the dreg defect of foundry goods, with by amendment technique, repairs die improvement product dreg defect compared with, save a large amount of time and expense, its effect more succinctly with efficiently; Unique gate core design, while fixing screen pack, is that the flow velocity of iron liquid is more steady, reduces the probability of molten iron slag making.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
A kind of filtering type cup, as shown in Figure 1: the uncovered cup 1 that it comprises a top accommodation molten iron, bottom is sand mold 5, sand mold side is provided with the sprue 2 communicated with molten iron, sprue 2 bottom is connected with the cross gate 3 be parallel to each other successively, the end of undermost cross gate 3 is connected with the afterbody sprue 6 corresponding with above-mentioned sprue 2 communicated with foundry goods, places screen pack 4 between the above-mentioned cross gate 3 be parallel to each other.
The described cross gate 3 be parallel to each other is two.
Described cup 1 cross sectional shape is rectangular shape, and it is large volume structure that cup top holds molten iron, and the sand mold 5 of bottom is entity structure.
Described screen pack 4 is honeycomb fashion screen pack.
First, the weight of molten iron of filtering as required, calculates the screen pack quantity that mouth of a river basin needs application;
The principle that screen pack 4 quantity is selected is: general weight is at 1Kg-290Kg, and use one piece of screen pack, screen pack area of section is 80mm-150mm*80mm-150mm, and weight of molten iron is (250Kg-290 Kg) X times, then use X screen pack.
Secondly, screen pack should be pressed in the bottom of fuse, in case wooden dipper rises, therefore increases a gate core.And back-up sand groove is set in the both sides of fuse, in case fuse hikes up under iron buoyancy of water, the upper strata cross gate of this cup bottom is directly taken out of by gate core.
