Abstract
The invention relates to a box stacking and pouring technical method for an automobile brake disc. The method comprises the following steps: modeling, loam core feeding, box stacking and pouring. The box stacking pouring is used for successfully solving the defects brought by a casting process adopted in the casting industry at present, and successfully and organically integrating advantages of all processes. The method is implemented by using the characteristics of parts, such as the brake discs, which are flat and small in size.
Description
Technical field
The present invention relates to a kind of stack pouring process, especially a kind of automobile brake disc stack pouring process.
Background technology
It is more and more wider that current automobile enters family, and particularly rural market is enlivened.China's car sales volume is with 2,000 ten thousand surges of year sales volume in recent years, and China's manufacturing industry also reaches its maturity.Domestic parts rate reaches more than 60%.The automobile localization rate of parts and components will reach more than 90% from now on.Its staple market is not only confined to domestic market, is also expected to capture world market.
Car brake disc, also referred to as disk brake, is a core part in car.It belongs to safety member, its complex process, and material requires high, and the accuracy of manufacture also requires tight especially.It is not long that start-up time is gone back in current domestic production domesticization, its core difficult point is in casting technique, domestic many producers mainly adopt the casting of lost foam casting, precoated sand, tide mould sand casting at present, but all there is shortcoming, do not reach the requirements such as technique, cost and quality, although the advantage that lost foam casting has its casting concentrated, because white mould gas forming amount causes casting defect greatly.Precoated sand casting due to cost more high-leveled and difficult with promote, tide mould sand casting due to single-piece cast work situation dispatch a person work be difficult to adapt to high-temperature operation.
Summary of the invention
The object of this invention is to provide a kind of automobile brake disc stack pouring process.
The present invention adopts following technical solution: this automobile brake disc stack pouring process, comprises the following steps:
(1) moulding: the under casing being placed with brake disc module is placed in Static Pressure Molding Machine through noting husky moulding, static pressure tide mould sand green compression strength is 40 ~ 50 kPa, be deposited on folded case station after having made type, again by be placed with brake disc module molding box in Static Pressure Molding Machine through noting husky moulding, repeat molding box moulding, static pressure tide mould sand green compression strength is 40 ~ 50 kPa;
(2) loam core under: manually precoated sand loam core is placed in brake disc die cavity;
(3) folded case: after molding box is layering, accurate and under casing and top box are located conjunction and stacked by alignment pin, each molding box is locked by button case wedge respectively, each case is tightly buckled and is stacked by box locking mechanism further, prevent from rising case during cast, anti-arch cover plate through clamping screw be fixed on top box prevents cast time arch box;
(4) pour into a mould: after folding case, upper line is poured into a mould successively, and molten iron pours into through sprue channel open, and gas is discharged through air-vent, finally obtains qualified brake disc castings.
The applicable trade mark of described molten iron is casting pig or spheroidal graphite cast-iron or alloy cast iron.
The present invention has following beneficial effect: folded case casting successfully solves the shortcoming that casting technique that current casting industry adopts is brought, and various process advantage has organically been concentrated in success, be characterized according to this kind of flat, feature that volume is little again of brake disc.Adopt the every case of single case moulding 4 brake discs, separately add under casing and the upper and lower joint sealing of top box, middle folded 6 layers, totally 24 parts.It is better than the amount of evaporative pattern, evaporative pattern one case can make tens just similar, and save sprue channel open etc., folded case casting adopts tide mould sand static press moulding, lower than precoated sand cost.The cast of folded case casting ratio tide mould sand list case maximally solves the puzzlement of cast workman high-temperature operation, and single case cast is wanted to water for one case one case, and workman's high-temperature operation is very arduous.And stack pouring list case just can water 6 casees.Available bull ladle vehicling operation can, with the casting of numerical control pouring truck, be also that casting industry realizes the desirable technique of automation.
