Abstract
The utility model provides a sand mould mould for nano powder iron and steel casting of modifying, have the different ceramic filter screen of diameter on the runner part runner that leaks hopper -shaped, water the bottom and do the sunken of buffering metal liquid, the pushing off the slag groove of cross gate design secondary pushing off the slag, to press the nano powder modifier of slabbing to put into between two ceramic filter screens, pouring -in metal liquid, under the impact of metal liquid, the nano powder additive fills into the sprue along with metal liquid, the pottery filter screen still can play the pushing off the slag effect except that placing the nanometer modified powder, metal liquid dashes the recess and obtains the buffering, secondary pushing off the slag effect is played to metal liquid in the pushing off the slag groove. The mould can be avoided nano powder modifier misce bene to smelt and float in metal liquid upper strata when adding and cause great scaling loss, caving in and having played fine cushioning effect, reduced the impact to the sand mould, metal liquid cleanliness is guaranteed in twice pushing off the slag, reduces the existence that the sediment was pressed from both sides in the oxidation.
Description
Technical field
This utility model relates to molded technology field, particularly relates to a kind of sand mold mould for nanometer powder modified steel iron castings.
Background technology
Sand casting is cheap and easy to get due to its Modeling Material used, Casting mold manufacturing is easy, used clay damp sand is after suitable sand processes, the overwhelming majority is the most recyclable to be used again, the cycle of manufacture casting mold is short, work efficiency is high and can manufacture, so for a long time, the always basic technology in Foundry Production.Nanometer powder modified steel iron castings has become the important means improving iron and steel casting performance, but common adding at smelting furnace easily causes the bigger scaling loss of nanometer powder, increase production cost, and its content is difficult to accurately control, after interpolation, nano modification powder easily floats on molten metal surface, is difficult to mix homogeneously, and in part, the segregation of nanometer powder is bigger, nanometer powder modifying agent is being put into sand mold mould by therefore design one, adds nanometer powder the most necessary to solve the problems referred to above in filling type.
Summary of the invention
For above-mentioned minimizing scaling loss, reducing burning into sand defect, reduce oxidation waste residue problem, improve casting quality, the purpose of this utility model is to provide a kind of sand mold mould for nanometer powder modified steel iron castings, meet nano modification powder mix homogeneously, the requirement that scaling loss amount is few.
This utility model realizes by the following technical solutions
A kind of sand mold mould for nanometer powder modified steel iron castings, including upper die and lower die, being provided with cast gate in upper mold, be designed to funnel-form at cast gate, mold has the upper model cavity formed that caves inward, lower mold has the lower mold die cavity formed that caves inward, after upper die and lower die matched moulds, upper model cavity and lower mold die cavity cooperatively form mold cavity, are positioned at the inside of cast gate and are provided with and fix ceramic filter screen with upper mold, on ceramic filtering, lower leaf is arranged, and is provided with the cavity placing nanometer powder between levels；Running channel is connected with cast gate, and the lower mold of the bottom being positioned at running channel is provided with depression；The passage that foundry goods chamber is connected with running channel is provided with pushing off the slag groove；
Preferably, in funnel-form at cast gate, cast gate place the different ceramic filter screen of 2 pieces of diameters the most respectively.
In this utility model, the nanometer powder modifying agent being pressed into lamellar is put between two panels ceramic filter screen, pour into molten metal, under the percussion of molten metal, nanometer powder additive is filled with sprue with molten metal, and ceramic filter screen may also function as pushing off the slag effect in addition to placing nano modification powder, molten metal is flushed to recess and is buffered, molten metal is played secondary pushing off the slag effect by pushing off the slag groove, it is ensured that the cleaning of molten metal, in last liquid metal filling to foundry goods.This mould can be by nanometer powder modifying agent mix homogeneously, it is to avoid melting floats on molten metal upper strata and causes bigger scaling loss when adding；Depression serves good cushioning effect, decreases the percussion to sand mold, therefore can be substantially reduced the burning into sand defect of foundry goods, improves the quality of foundry goods；Twice pushing off the slag ensures molten metal cleannes, reduces the existence of oxide slag inclusion.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sand mold mould for nanometer powder modified steel iron castings that the utility model proposes.
Detailed description of the invention:
As shown in Figure 1, a kind of sand mold mould for nanometer powder modified steel iron castings that the utility model proposes, including upper mold 1 and lower mold 2, cast gate 3 it is provided with in upper mold 1, upper mold 1 has the upper model cavity formed that caves inward, lower mold 2 has the lower mold die cavity formed that caves inward, and after upper die and lower die matched moulds, upper model cavity and lower mold die cavity cooperatively form mold cavity.Being positioned at the inside of cast gate 3 to be provided with and fix ceramic filter screen 4 with upper mold 1, cast gate 3 is in funnel-form, and upper ceramic filter screen diameter lays respectively at the both sides up and down of cast gate 3 more than lower ceramic filter screen, and ceramic filter screen 4 is connected with upper mold 1, and nanometer powder 9 is positioned over ceramic filter screen 4.Running channel 5 is connected with cast gate 3, and depression 6 is positioned in the lower mold 2 of running channel bottom；The centre that foundry goods 8 is connected with running channel 5 is provided with pushing off the slag groove 7.
This utility model is when implementing, molten metal pours into from cast gate 3, under the percussion of molten metal, the nanometer powder 9 being positioned in ceramic filter screen 4 is filled with sprue 5 with molten metal, and ceramic filter screen 4 may also function as pushing off the slag effect except placing in addition to nano modification powder, and molten metal is flushed to cave at 6 and is buffered, when flowing through pushing off the slag groove 7, molten metal plays secondary pushing off the slag effect, it is ensured that the cleaning of molten metal, in last liquid metal filling to foundry goods 8.This mould can be by nanometer powder modifying agent mix homogeneously, it is to avoid melting floats on molten metal upper strata and causes bigger scaling loss when adding；Depression serves good cushioning effect, decreases the percussion to sand mold, therefore can be substantially reduced the burning into sand defect of foundry goods, improves the quality of foundry goods；Twice pushing off the slag ensures molten metal cleannes, reduces the existence of oxide slag inclusion.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; according to the technical solution of the utility model and inventive concept equivalent or change in addition thereof, all should contain within protection domain of the present utility model.
