Abstract
The invention relates to a forming technology of a riser bush. The forming technology is characterized by comprising the following processes: 1) blowing sand; 2) leveling off; 3) extruding; 4) disassembling a lower die; 5) dissembling a leaked die plate; 6) arranging a drying plate; 7) slightly moving the upper die; and 8) completely removing the die. Compared with conventional forming technology, the forming technology provided by the invention has the advantages that the dies are not needed to be overturned, thus the defects that the die is overturned to result in deformation and cracking on a riser can be reduced, and as a result, the quality of the formed riser is improved. The forming technology is applicable to both manual modeling and mechanical modeling. By adopting the forming technology for producing, the labor intensity of workers is greatly reduced; and the inner heating and curing process can be saved once the mechanical modeling is carried out, so that the time for waiting for inner curing is saved, and as a result, the working efficiency is improved.
Description
Technical field
The present invention relates to casting and molding rising head technical field, particularly a kind of moulding process of riser buss.
Background technology
Rising head is to be arranged in the foundry goods manufacture process in the casting mold for storage feeding a casting molten metal bath, and exhaust is arranged, collects the cavity of slag effect.In actual production process, for improving the product yield of foundry goods, reduce the molten metal in the rising head, the heat preservation riser buss can be set in the position of rising head.At present, the moulding process of riser buss has two kinds:
The one, hand moulding technique sees also Fig. 2, is specially:
The first step: the upper die and lower die matched moulds, at the cavity injection sand of two moulds formation;
Second step: utilize scraper plate that the unnecessary sand in patrix surface is struck off;
The 3rd step: push sand mold downwards with pressing plate;
The 4th step: 180 ° of die flips make pressing plate forward below to;
The 5th the step: on move counterdie, withdraw from counterdie;
The 6th step: cover bake plate;
The 7th step: mould carries out 180 ° of upsets again, makes bake plate forward below to, and pressing plate forwards the top to;
The 8th step: on move pressing plate and patrix, withdraw from pressing plate and patrix, then bake plate and sand mold are sent into the baking oven baking.
There is die flip twice in above-mentioned hand moulding technique, easily causes the sand mold demoulding in the die flip process, and causes riser buss the defectives such as distortion, cracking to occur, in addition, adopts this kind formative technology also to have the large problem of labour intensity.
The 2nd, utilize machinery equipment to carry out the technique of moulding, this kind formative technology can heat mould before die sinking, and riser buss is hardened in type.Owing to there is heating process, so the moulding time is longer, operating efficiency is lower.
Summary of the invention
The present invention provides a kind of riser buss of avoiding distortion, cracking to occur for solving the technical problem that exists in the known technology, improves the riser buss Forming Quality, reduces labour intensity, not only has been applicable to hand moulding but also has been applicable to the riser buss moulding process of machine molding.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of moulding process of riser buss is characterized in that, comprises following operation:
1) penetrate sand: place stripping pattern plate at counterdie, the upper die and lower die matched moulds is at the cavity injection sand of two moulds and stripping pattern plate formation;
2) strike off: utilize scraper plate that the unnecessary sand in patrix surface is struck off;
3) extruding: push sand mold downwards with pressing plate;
4) remove mould: counterdie moves down, and withdraws from counterdie;
5) remove stripping pattern plate: stripping pattern plate moves down, and withdraws from stripping pattern plate;
6) place bake plate: below patrix and sand mold, place bake plate, make bake plate hold patrix and sand mold;
7) little patrix that moves: pressing plate is motionless, moves on the patrix, and sand mold and patrix are disengaged;
8) the fully demoulding: move down bake plate, sand mold is shifted out from patrix fully, then send into the baking oven baking.
Advantage and good effect that the present invention has are:
Therefore this moulding process does not need to carry out die flip than existing moulding process, reduces the defectives such as distortion, cracking that cause riser buss because of the die flip demoulding, thereby has improved the Forming Quality of riser buss.This moulding process both had been applicable to hand moulding, also was applicable to machine molding.Adopt this explained hereafter, but decrease workman's labour intensity; And when adopting machine molding, do not need heat hardening in the type, thereby saved the described stand-by period of sclerosis in the type, and then improved operating efficiency.
Description of drawings
Fig. 1 is process chart of the present invention;
Fig. 2 is hand moulding process chart in the prior art.
Among the figure: 1, counterdie; 2, stripping pattern plate; 3, patrix; 4, scraper plate; 5, pressing plate; 6, sand mold; 7, bake plate.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and be described in detail as follows:
See also Fig. 1, a kind of moulding process of riser buss comprises following operation:
1) penetrate sand: place stripping pattern plate 2 at counterdie 1, patrix 3 and counterdie matched moulds are at the cavity injection sand of two moulds and stripping pattern plate formation.
2) strike off: utilize scraper plate 4 that the unnecessary sand in patrix surface is struck off;
3) extruding: push sand mold 6 downwards with pressing plate 5.
4) remove mould: counterdie moves down, and withdraws from counterdie.
5) remove stripping pattern plate: the plate stripping pattern plate moves down, and withdraws from stripping pattern plate, and at this moment, under the rubbing action between sand mold and the patrix inwall, sand mold is vacant state.
6) place bake plate: below patrix and sand mold, place bake plate 7, make bake plate hold patrix and sand mold.Concrete, can insert bake plate or introduce bake plate from the below from horizontal direction.
7) little patrix that moves: pressing plate is motionless, moves 2-5mm on the patrix, and sand mold and patrix are disengaged.
8) the fully demoulding: move down bake plate, sand mold is shifted out from patrix fully, then send into the baking oven baking.
Above-mentioned moulding process also is applicable to the manufacturing of core except being applicable to make the riser buss.
