Abstract
The utility model discloses a sand faced tooling applied to sand faced iron mould casting and particularly relates to a molten iron filter sprue cup for the sand faced iron mould casting. The molten iron filter sprue cup is characterized by comprising funnel-shaped sprue cup iron, wherein a sand faced layer is arranged on the internal wall of the sprue cup iron; and a flange is integrally arranged at the outlet end of the sprue cup iron. The cup can avoid casting defects arising from a pouring system, can filter molten iron, is simple and convenient in production operation and saves manufacture cost.
Description
Technical field
The utility model relates to the casting technique equipment, especially is applied to the Iron Mould Coated Sand casting with covering the sand frock.
Background technology
The Iron Mould Coated Sand casting belongs to one of Special Processes of Metal Castings, and its casting mold is on the metal mold inner chamber, to be covered with the skim precoated sand to form casting mold.Head-free casting is adopted in the Iron Mould Coated Sand casting, and running gate system is less relatively, and the molten iron recovery rate is high.Therefore with regard to the Iron Mould Coated Sand casting, it is particularly important that the pushing off the slag of molten iron just seems.Cup in the Iron Mould Coated Sand Foundry Production generally adopts green-sand to make, in casting process the green-sand intensity difference, moisture is arranged, can bring the defective of significant proportion to foundry goods.In order to improve the pushing off the slag effect of cup, in cup, place screen pack, generally to adopt the structure of double-deck cup, make actual production process become complicated.
The utility model content
The utility model technical problem to be solved is to overcome deficiency of the prior art and a kind of casting flaw that can avoid running gate system to bring is provided; Possess the filtration to molten iron simultaneously, production operation Iron Mould Coated Sand iron liquid easy, that practice thrift the cost of making filters cup.
The technical scheme that the utility model solves the problems of the technologies described above employing is: this Iron Mould Coated Sand iron liquid filters cup; It is characterized in that: comprise being funnelform cup swage; On cup swage inwall, be provided with and cover layer of sand, described cup swage port of export integrated setting flange.
The described cup swage of the utility model inside is placed with foam ceramic filter, ceramic filter mesh-shaped size and the inner chamber coupling that is provided with the cup swage that covers layer of sand.
The described sand layer thickness that covers of the utility model is 10-20mm.
The utility model compared with prior art has the following advantages: the utility model covers sand to cup swage inwall, and sand using amount is few, and it is good to cover the chiltern amount, does not have moisture, has eliminated drop, sand washing, gas hole defect that foundry goods produces because of cup.In cup, put into foam ceramic filter easily, the molten iron that pours into is filtered, good pushing off the slag effect is arranged.Behind the casting complete, screen pack floats automatically, makes the feeding passage of cup unimpeded, and the molten iron in the cup can carry out liquid feeding to foundry goods, helps obtaining fine and close foundry goods.Cup is made simple, and production operation is convenient.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cup Iron Mould Coated Sand view.
The specific embodiment
Referring to Fig. 2; Cup swage 1 is placed on the gating pattern 4; With artificial or penetrate the sand mode precoated sand is filled up the space between cup swage 1 and the gating pattern 4; Treat that precoated sand solidifies the back molding, what on cup swage 1 inwall, form thickness and be 10-20mm covers layer of sand 3, the demand of liquid towards molten iron when satisfying the foundry goods cooling.
Referring to Fig. 1, cup swage 1 integral body is funnel-form, at cup swage 1 port of export integrated setting flange 7, help the placement of cup and in casting process cup can not topple over and molten iron can not spill between cup and iron 6.Flange 7 extension circles are provided with the inclination angle, help shoveling cup easily behind the casting complete.Cup swage 1 inside is placed with foam ceramic filter 2, foam ceramic filter 2 shapes size and the inner chamber coupling that is provided with the cup swage 1 that covers layer of sand 3.Cup swage 1 material is a casting pig, can use repeatedly.Cover layer of sand 3 employings and use precoated sand of the same race, make things convenient for organization of production and management with the Iron Mould Coated Sand castings production.
Operation principle: cup is placed on swage down gate position, puts into cup to foam ceramic filter 2, can pour into a mould then.Because molten iron directly waters and on foam ceramic filter 2, pushes down foam ceramic filter 2 and can not float, and molten iron gets into die cavities through foam ceramic filter 2, and molten iron is well filtered, impurity in the molten iron and slag are kept off on foam ceramic filter 2 during cast.Behind the casting complete, because foam ceramic filter 2 is lighter than molten iron, foam ceramic filter 2 just floats automatically, makes the molten iron in the cup can be to carrying out liquid feeding in the casting mold, to guarantee finally to obtain the qualified foundry goods of dense structure.
Above content described in this specification only is to be illustrated what the utility model structure did.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; Only otherwise depart from the structure of the utility model or surmount the defined scope of these claims, all should belong to the protection domain of the utility model.
