Abstract
The utility model discloses a mould on train motor end cover casting mould, it includes the calligraphy or painting model body and locating piece, the locating piece is located on the calligraphy or painting model body, go up the mould at last position and the exhaust dead angle department installation core vent of filling, it has the air vent to go up to open on mould die joint and the psammitolite contact surface, according to product structure ejecting ejector pin of installation and ejecting release link, goes up the mould reverse side and according to shaping position shape, digs up the metal and form artifical forced air cooling temperature field control chamber. The utility model discloses adopt psammitolite casting mould to compare with domestic and international high speed train traction motor end cover, it is simple to adopt metal -mould low pressure casting mould structure, which is rapid and convenient for installation, and low worker labor intensity, good labor condition, it has reduced environmental pollution to need not the psammitolite energy saving, the foundry goods tissue that uses the metal -mould low pressure casting mould to produce simultaneously is fine and close, the profile is clear, internal and external surface is bright and clean, it is good that the uniformity is stabilized to the size, blank light in weight allowance is few, a high production efficiency is obtained, product appearance is of high quality, thus the cost is reduced.
Description
Technical field
The utility model relates to casting mould field, particularly a kind of train electric motor end cap casting mould patrix.
Background technology
Along with the develop rapidly of China Railway High-speed and the continuous lifting of bullet train speed, the locomotive that the lifting of speed just needs power more powerful, a proverb is had to say right " train runs a good foot complete in headstock band ", so traction electric machine is the heart of bullet train, its quality good or not is related to the high-speed cruising safety of whole locomotive.Traction electric machine end cap is a vitals on traction electric machine, and these parts will bear motor-driven load, and also require to have vibration damping efficiency, the ballistic work of mechanical property requirements-40 DEG C reaches 12J simultaneously.This product requirement is high simultaneously, not only will do surperficial magnetic powder inspection, and will clap X-ray, has not allowed any defect.In locomotive operation, the forward and backward end cap bearing chamber being arranged on traction motor support two ends supports the axletree of huge rotatory force, running up, under condition of work that alternate load is large, has high requirement to the casting property of forward and backward end cap.
Bullet train traction electric machine end cap is the key ensureing bullet train continuous service, is bullet train traction electric machine core component, required precision is high, manufacture difficulty is large, bearing load is large, work under bad environment.Conventional high rate train traction motor end cap is all cast steel structure, alleviates bullet train motor deadweight object in recent years in order to reach, and has successfully been adopted by bullet train electric motor end cap the Birmasil of high strength to replace cast steel alloy both at home and abroad.
Because bullet train traction electric machine end cap product size is large, complex structure, wall thickness uneven distribution, particularly ZL205A aluminium copper casting character is very poor, current domestic and international fast train traction motor end cap is all adopt sand casting process method, but find in actual production, productivity ratio is low, production environment is severe, labour intensity is large, yield rate is low, cost is high and serious waste of resources to adopt core casting to exist, and main is that alloy mechanical performance is unstable, product appearance is of poor quality, dimensional uniformity is bad.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of train electric motor end cap casting mould patrix, can alleviate blank weight, improves product mechanical performance and presentation quality, reduce costs the performance specification meeting bullet train traction electric machine end cap particular job.
Solution of the present utility model is achieved in that
A kind of train electric motor end cap casting mould patrix, it comprises mould body and locating piece; Locating piece is located on mould body; Patrix die joint and core contact surface have passage; Upper mould body reverse side, according to shaping position shape, is dug up metal and is formed artificial air-cooled temperature field control chamber; Upper mould body installs venting plug; Eject push rod and eject release link and be arranged on mould body.
Another technical scheme of the present utility model is on above-mentioned basis, and described patrix in the end fills position and venting plug is installed at exhaust dead angle place.
Another technical scheme of the present utility model is on above-mentioned basis, evenly installs eject push rod and eject release link according to product structure.
Another technical scheme of the present utility model is on above-mentioned basis, and the inner surface of supporting metal mold counterdie and the outer surface of metal mold patrix form foundry goods die cavity.
Before die casting, first by mould abrasive jet cleaning, preheating, spray paint, spray paint thickness and heat insulating ability are according to order is from thick to thin and from strong to weak from top to bottom, and mold preheating temperature is according to from top to bottom sequentially from high to low, and counterdie cast gate need install circular filter net.With the hot box core mold punch down chamber core manufactured and feeding head core, then special in core surface brush coating, core must be come out of the stove use before IR oven 100 degree of bakings 1 hour cast.Mould is in order to build the temperature field of consecutive solidification in casting process, and patrix adopts manually air-cooled.
The beneficial effects of the utility model: compared with adopting sand core casting die with domestic and international bullet train traction electric machine end cap, adopt simple, the quick for installation convenience of metal-mold low-pressure casting mould structure, labor strength low, working condition is good, environmental pollution is decreased without the need to core economize energy, the cast structure densification simultaneously using metal-mold low-pressure casting mould to produce, clear-cut, surfaces externally and internally are bright and clean, dimensionally stable uniformity is good, the lightweight allowance of blank is few, production efficiency is high, product appearance quality is good, reduces cost.Particularly achieve metal-mold low-pressure casting when ZL205A aluminium copper casting character is very poor, product tensile strength > 450MPa, percentage elongation > 10%, hardness HB > 120, core casting is not high for mechanical performance, and mechanical performance almost can match in excellence or beauty with cast steel.
Accompanying drawing explanation
