Abstract
The invention discloses a solar top plate blank casting mould and a casting technique. The solar top plate blank casting mould comprises a bottom plate and a top plate model; and a running gate is formed in the bottom plate, the top plate model is communicated with the running gate through a flow gate, and a steel ring and a sand core are embedded into the top plate model. The top plate model is provided with rise feeding, a key groove blank and a casting blank are cast together and then machined together, and the previous two-step machining and assembling method is achieved in one step. Thus, the producing efficiency is improved, products can be integrally formed, only machining error is generated, and the product accuracy is higher. Furthermore, twice machining and assembling is avoided, the cost is saved, and environment friendliness is achieved.
Description
Technical field
The present invention relates to casting processing technique field, particularly the double-deck casting mould of a kind of compressor scroll plate blank and casting technique thereof.
Background technology
Compressor scroll plate vortex part only has 5.9mm thick, and have 42.5mm high, side allowance only has 1.5mm, and casting requires high, and difficulty is large.Former technique scroll plate technique is individual layer, and go out 6 blanks for 1 case, production efficiency is low, and cost is high.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides one and enhancing productivity, the double-deck casting mould of cost-effective compressor scroll plate blank and casting technique thereof.
The present invention in order to the technical scheme solving its technical problem and adopt is: the double-deck casting mould of a kind of compressor scroll plate blank, comprises base plate; Base plate is provided with a down gate; And by scroll plate model that ingate is communicated with down gate; Described scroll plate model and core; Scroll plate model has riser feeding.
The double-deck casting technique of a kind of compressor scroll plate blank, comprises the following steps:
1) Mold Making: according to top board section factor, the moulding mould that design model needs as described in the appended claim 1;
2) core is made: the cavity shape core box heating in foundry goods made by the quartz sand sand containing resin;
3) mulling: be mixed and made into molding sand with quartz sand and clay etc.;
4) moulding: scroll plate mould step 1 made is arranged on moulding machine, adopts the mixed molding sand of step 3) to manufacture sand mold; And core is put as in made sand mold; ;
5) melting: the raw material making top board blank is placed in smelting furnace and carries out melting, form molten iron; The chemical composition weight percentage of top board blank is: C:3.0-3.2%; Si:1.5-1.7%; Mn:0.8-1.0%; P :≤0.06%; S:0.06-0.08%; Cu:0.5-0.7%, all the other are Fe and inevitable impurity; ;
6) pour into a mould: add in casting ladle casting ladle hold the inovulant of molten iron gross weight 0.7%; When molten iron temperature in smelting furnace reaches 1510 ~ 1540 DEG C, poured into by molten iron in casting ladle and molten iron is fully mixed with inovulant, the temperature of described cast controls to be 1380 ~ 1430 DEG C, and coming out of the stove to be poured controls within 8 minutes; ;
7) knockout: after the foundry goods in sand mold cools 1.5 hours, is transported in viberating knock-out machie, makes its sand mold, core separates with foundry goods;
8) blank is separated: separated from running gate system by knocking by scroll plate foundry goods after FCL rough polishing;
9) blank polishing; Burr and ingate are polished flat by abrasive machine by scroll plate blank;
10) blank ball blast: the blank essence after polishing is thrown, the fine impurities on surface is removed, and makes its smooth surface; ;
11) vanning warehouse-in: foundry goods essence thrown is packed by the packing instructions of client, warehouse-in.
The invention has the beneficial effects as follows: the double-deck casting mould of compressor scroll plate blank of the present invention and casting technique thereof will make bilayer by core; become and go out 12 blanks for 1 case; greatly enhance productivity; save cost; environmental protection; by the optimization that double-deck core procedure and pouring technology design, the control of pouring temperature, chemical composition overcomes above shortcoming, and percent defective in this product Foundry Works is controlled within 5%.
