Abstract
The present invention relates to a kind of moulding process of riser buss, be characterized in, comprise following operation: 1) penetrate sand; 2) strike off; 3) extrude; 4) mould is removed; 5) stripping pattern plate is removed; 6) bake plate is placed; 7) micro-ly patrix is moved; 8) demoulding completely.This moulding process, compared to existing moulding process, does not need to carry out die flip, therefore reduces the defect such as distortion, cracking causing rising head because of the die flip demoulding, thus improves the Forming Quality of rising head.This moulding process was both applicable to hand moulding, was also applicable to machine molding.Adopt this explained hereafter, significantly can reduce the labour intensity of workman; When adopting machine molding, do not need heat hardening in type, thus saved the required stand-by period of sclerosis in type, and then improve operating efficiency.
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 arranged in foundry goods manufacture process for storage feeding a casting molten metal bath in casting mold, and have the cavity of exhaust, the effect of collection slag.In actual production process, for improving the product yield of foundry goods, reducing the molten metal in rising head, heat preservation riser buss can be set in the position of rising head.At present, the moulding process of riser buss has two kinds:
One is hand moulding technique, refers to Fig. 2, is specially:
The first step: upper die and lower die matched moulds, penetrates sand in the cavity that two moulds are formed;
Second step: utilize scraper plate to be struck off by the sand of patrix excess surface;
3rd step: extrude sand mold downwards with pressing plate;
4th step: die flip 180 °, makes pressing plate forward bottom to;
5th step: above move counterdie, withdraw from counterdie;
6th step: cover bake plate;
7th step: mould carries out 180 ° of upsets again, and make bake plate forward bottom to, pressing plate forwards the top to;
8th step: above move pressing plate and patrix, withdraws from pressing plate and patrix, then bake plate and sand mold is sent into baking oven baking.
, there is twice die flip in above-mentioned hand moulding technique, in die flip process, easily causes the sand mold demoulding, and cause riser buss to occur the defects such as distortion, cracking in addition, adopting this kind of formative technology also to there is the large problem of labour intensity.
Two is the technique utilizing machinery equipment to carry out moulding, this kind of formative technology, can heat, riser buss is hardened in type before die sinking to mould.Owing to there is heating process, so the moulding time is longer, operating efficiency is lower.
Summary of the invention
The present invention provides one to avoid riser buss to occur distortion, cracking for solving in known technology the technical problem that exists, improves riser buss Forming Quality, reduces labour intensity, has not only 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 existed in solution known technology is:
A moulding process for riser buss, is characterized in that, comprises following operation:
1) penetrate sand: on counterdie, place stripping pattern plate, upper die and lower die matched moulds, in the cavity that two moulds and stripping pattern plate are formed, penetrate sand;
2) strike off: utilize scraper plate to be struck off by the sand of patrix excess surface;
3) extrude: extrude sand mold downwards with pressing plate;
4) remove mould: counterdie moves down, withdraw from counterdie;
5) remove stripping pattern plate: stripping pattern plate moves down, withdraw from stripping pattern plate;
6) bake plate is placed: place bake plate in the below of patrix and sand mold, make bake plate hold patrix and sand mold;
7) micro-ly patrix is moved: pressing plate is motionless, and patrix moves, and sand mold and patrix are disengaged;
8) demoulding completely: move down bake plate, shifted out completely by sand mold from patrix, then sends into baking oven baking.
The advantage that the present invention has and good effect are:
This moulding process, compared to existing moulding process, does not need to carry out die flip, therefore reduces the defect such as distortion, cracking causing riser buss because of the die flip demoulding, thus improves the Forming Quality of riser buss.This moulding process was both applicable to hand moulding, was also applicable to machine molding.Adopt this explained hereafter, significantly can reduce the labour intensity of workman; And when adopting machine molding, do not need heat hardening in type, thus saved the sclerosis described stand-by period in type, and then improve operating efficiency.

Fig. 2 is hand moulding process chart in prior art.
In figure: 1, counterdie; 2, stripping pattern plate; 3, patrix; 4, scraper plate; 5, pressing plate; 6, sand mold; 7, bake plate.
Detailed description of the invention
For summary of the invention of the present invention, Characteristic can be understood further, hereby exemplify following examples, and be described in detail as follows:
Refer to Fig. 1, a kind of moulding process of riser buss, comprise following operation:
1) penetrate sand: on counterdie 1, place stripping pattern plate 2, patrix 3 and counterdie matched moulds, in the cavity that two moulds and stripping pattern plate are formed, penetrate sand.
2) strike off: utilize scraper plate 4 to be struck off by the sand of patrix excess surface;
3) extrude: with pressing plate 5 extruding sand mold 6 downwards.
4) remove mould: counterdie moves down, withdraw from counterdie.
5) remove stripping pattern plate: plate stripping pattern plate moves down, and withdraws from stripping pattern plate, now, under the rubbing action between sand mold and patrix inwall, sand mold is vacant state.
6) bake plate is placed: place bake plate 7 in the below of patrix and sand mold, make bake plate hold patrix and sand mold.Concrete, can bake plate be inserted from horizontal direction or introduce bake plate from below.
7) micro-ly patrix is moved: pressing plate is motionless, and patrix moves 2-5mm, and sand mold and patrix are disengaged.
8) demoulding completely: move down bake plate, shifted out completely by sand mold from patrix, then sends into baking oven baking.
Above-mentioned moulding process manufactures except riser buss except being applicable to, and is also applicable to the manufacturing of core.
