Abstract
The utility model discloses an investment casting device. The structure of the special device is a moulding vessel with a through hole at the bottom, and the through hole is connected with a vacuum pump. The moulding vessel is provided with a perforated lid on the top, and the edge of the moulding vessel and the edge of the lid of the mouding vessel are enclosed structure. An opening arranged in the lid is matched with the inlet of the hollow shell. The utility model has the advantages of simple structure, low cost, short molding time, 100 percent production success rate, and reduction of intensity of labor.
Description
Affiliated technical field
The utility model relates to a kind of Casting Equipment, relates in particular to a kind of turbo blade of production turbocharger and model casting special equipment of lever of being used for.
Background technology
The turbo blade of conventional art production turbocharger and turbine bar are done wax pattern with mould earlier; Drench husky then; Put in the refractory material and be stained with drenching husky wax pattern, and then drench huskyly, so repeatedly about 7 times, the tension in order to bear casting the time so need enough thickness, forms the wax shell; Then above-mentioned ready-made wax housing is put into the oven baking, the wax that melts is poured out, continue baking, so just formed air-locked hollow shell.In above-mentioned hollow shell, pour casting liquid then into, form finished product.Because above-mentioned hollow shell is air-locked, when casting, the residual gas row in the casting liquid does not come out, and causes the casting failure.
And the employing vacuum casting, just the above-mentioned hollow shell of producing is put into vacuum drying oven, need not carry out under the conditions of air having, owing to there is not air casting liquid to be difficult for flowing in the hollow shell, this just need put into hollow shell the roasting furnace roast,, be heated to about 800 degree, and then transfer in the vacuum drying oven and cast.Energy resource consumption is big, and yield rate is low, wastes a large amount of resources, and production equipment has high input, and the blade shape angle is unreasonable, and quality is heavy, and the startup of impeller is insensitive, response lag.
The utility model content
Technical problem to be solved in the utility model provides a kind of model casting equipment, and it has solved complex process, and energy resource consumption is big, yield rate is low, and production equipment has high input, and the blade shape angle is unreasonable, quality heavily waits problem, and the good product quality of casting is saved resource.
In order to solve the problems of the technologies described above, the utility model is achieved in that it is to be made of following structure: pouring container, the bottom of pouring container is provided with through hole, through hole is connected with vavuum pump, the top of pouring container is provided with lid with holes, the edge of pouring container and the edge of lid are enclosed construction, cover and are provided with opening, and opening should be complementary with the inlet of hollow shell.
Advantage of the present utility model and effect are: production equipment of the present utility model is simple, equipment cost is low, and casting time is short, and product cost reduces more than one times, the product success rate reaches 100%, reduced working strength of workers, the yield rate height, production equipment drops into little, the blade shape angle is reasonable, light weight, the startup sensitivity of impeller, response lag is less.Can be for country to save a large amount of resources, sharp and enforcement has extensive market prospects.
