Abstract
The utility model discloses a wax injection forming device used for a large-scale thin-wall part and capable of improving investment pattern precision casting. The wax injection forming device comprises a metal mould, wherein a vacuum bag is sleeved outside the metal mould, a vacuum duct connected with a vacuum pump is arranged on one side of the side wall of the vacuum bag, a metal mould wax injection opening connected with the wax injection pipe of a wax injection press is arranged on the other side of the side wall of the vacuum bag, and the wax injection pipe and the connector of the vacuum bag are sealed by using an adhesive tape. The wax injection forming device ensures that the mould is vacuumized before wax injection, due to the adoption of the principle of negative pressure inside the mould, the large-scale thin-walled part can be formed through wax injection press in one step by using a common wax injection press, and a sound wax pattern surface can be obtained.
Description
Technical field
The utility model relates generally to precision-investment casting molding field, and the wax-pattern that is particularly useful for adopting precision-investment casting to produce the large thin-wall parts of Aeronautics and Astronautics is made.
Background technology
Along with the development of precision-investment casting, many large thin-wall housings, casing, engine structure spare etc. all adopt melted module precise casting technology production in space flight, the aviation.Early stage general with forging and foundry goods, rivet or be welded to form after the employing machined, cast out with the precision-investment casting Integratively now, not only reduce material consumption, and simplify technology, save man-hour, economic benefit is fairly obvious.But in whole casting process, also there is a series of technical barrier, as pressing wax, the disposable shaping of cast etc.Method in this patent adopts common wax injector can make the disposable pressure wax moulding of large thin-wall element, and can obtain intact wax-pattern surface.
The utility model content
The purpose of this utility model is exactly in order to remedy the defective of prior art, a kind of device that improves investment pattern precision casting large thin-wall element shaping investment pattern to be provided.
The utility model adopts following technical scheme:
A kind of device that improves the wax moulding of investment pattern precision casting large thin-wall element pressure, comprise metal die, it is characterized in that: described metal die is with vacuum bag outward, the sidewall of described vacuum bag is provided with the vacuum pipe that is connected with vavuum pump on one side, the sidewall another side of described vacuum bag also is provided with the metal die casting mouth that is connected with the casting pipe of wax injector, and described casting pipe and vacuum bag interface adopt rubber belt sealing.
The beneficial effects of the utility model:
The utility model is will to vacuumize in the mould before casting, utilizes principle of negative pressure in the mould, adopts common wax injector can make the disposable pressure wax moulding of large thin-wall element, and can obtain intact wax-pattern surface.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, metal die, 2, vacuum bag, 3, vacuum pipe, 4, vavuum pump, 5, adhesive tape, 6, the casting pipe, 7, the casting mouth.
The specific embodiment:
As shown in Figure 1, a kind of device that improves the wax moulding of investment pattern precision casting large thin-wall element pressure, comprise metal die 1, the described metal die 1 outer vacuum bag 2 that is with, the sidewall of described vacuum bag 2 is provided with the vacuum pipe 3 that is connected with vavuum pump 4 on one side, the sidewall another side of described vacuum bag 2 also is provided with the metal die casting mouth 7 that is connected with the casting pipe 6 of wax injector, and described casting pipe 6 adopts adhesive tape 5 sealings with vacuum bag 2 interfaces.
