Abstract
The utility model relates to a low-pressure casting device. The low-pressure casting device mainly solves the problems that auxiliary working procedures of an existing low-pressure casting process are complex, the technological process is tedious, resource waste of overall equipment is caused and maintenance of the equipment is complex. The low-pressure casting device is characterized in that the bottom end of a liquid-raising guide pipe stretches to the bottom of a sealed container but does not make contact with the bottom, the top end of the liquid-raising guide pipe is fixedly connected with a sealing cover, a casting mould is fixed by a fastening bolt, a pouring gate communicated with the liquid-raising guide pipe and the casting mould is formed in the sealing cover, a piston capable of carrying out compression freely is arranged on the sealing cover and extends into the sealed container, a control device is connected to the outer end of the piston, and mechanical control and manual control can be achieved through the control device outside the piston. The low-pressure casting device is reasonable in structure, convenient and fast to operate and convenient to use and maintain, reduces resource waste of the casting equipment, reduces investment and saves energy, and the technological process is simple.
Description
Technical field
The utility model relates to foundry machinery technical field, is specifically related to a kind of low-pressure casting apparatus.
Background technology
Casting refers to will be in room temperature treats the processing mode of its coagulation forming for mold liquid but that in the near future curing material is poured into given shape.Be cast material and mostly be and be solid-state originally but be heated to liquid metal, and molding material can be husky, even pottery of metal.In response to different requirements, the method for use also can be different, but total operation principle is all to utilize to pass into dried compressed air effect in airtight container, makes to produce pressure differential with casting mold die cavity in airtight container, and then enter in predetermined casting mold.But dried compressed air is generally through super-dry compressor processes, has so increased the aided process of whole casting process, technological process complexity, not easy to operate, energy waste and use and maintenance inconvenience.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of low-pressure casting apparatus.The aided process that has mainly solved existing whole casting process is loaded down with trivial details, technological process complexity, be difficult to operation, the problem of energy waste and inconvenient maintenance, this low-pressure casting apparatus is rational in infrastructure, technological process is simple, simple operation, the wasting of resources of reduction Casting Equipment, reduced investment, save the energy, easy maintenance.
The technical scheme that the utility model adopts is: a kind of low-pressure casting apparatus, comprise airtight container, rise fluid catheter, seal cover, casting mold and piston, the described fluid catheter bottom that rises extends sealing container bottom, but still touch bottom, stalk top is fixedly connected with seal cover, described casting mold is close to fixing bolt and fixes, described seal cover is provided with UNICOM and rises the cast gate of fluid catheter and casting mold, described seal cover is provided with piston that can Free Compression, described piston extends in airtight container, and piston outer end is connected with control device.
Described airtight container is crucible.
Stalk bottom is provided with damper.
Between airtight container and seal cover, fixed by fastening bolt.
Piston arranges varying number and size as required.
The control device of piston outside can also can manually be controlled in machinery control.
The beneficial effects of the utility model are: owing to taking technique scheme, effectively controlled back work amount in casting process, this low-pressure casting apparatus is rational in infrastructure, technological process is simple, simple operation, the wasting of resources of reduction Casting Equipment, reduced investment, saves the energy, easy maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure 1, airtight container; 2, rise fluid catheter; 3, seal cover; 4, casting mold; 5, piston; 6, damper.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
A kind of low-pressure casting apparatus as shown in Figure 1, comprise airtight container 1, rise fluid catheter 2, seal cover 3, casting mold 4 and piston 5, described fluid catheter 2 bottoms that rise extend airtight container 1 bottom, but still touch bottom, stalk 2 tops are fixedly connected with seal cover 3, described casting mold 4 is close to fixing bolt and fixes, described seal cover 3 is provided with UNICOM and rises the cast gate of fluid catheter 2 and casting mold 4, described seal cover 3 is provided with piston 5 that can Free Compression, described piston 5 extends in airtight container 1, and piston 5 outer ends are connected with control device.
Described airtight container 1 is crucible, and airtight container 1 is fusing and the space of refined metals liquid, guarantee low pressure casting liquid fluidity, the completing smoothly of casting mold 4.
Described stalk 2 bottoms are provided with damper 6, effectively reduce the metal splash while cast and the impact of crucible bottom residual metallic is stirred, and have controlled the inclusion defect of foundry goods.
Between airtight container 1 and seal cover 3, fixed by fastening bolt.
Piston 5 arranges varying number and size as required.
The control device of piston 5 outsides can also can manually be controlled in machinery control.
Operation principle: install a certain amount of aluminium alloy in airtight container 1, the damper that rises fluid catheter 2 bottoms is flooded by aluminium alloy, utilize External Force Acting at the uniform velocity to promote piston 5, the interior air of airtight container 1 is compressed, act on the metal bath surface that keeps certain pouring temperature, cause in airtight container 1 and the pressure differential of casting mold 4 die cavities, make aluminium alloy under the effect of gas pressure, rise along stalk 2, enter reposefully die cavity by cast gate, and suitably increase pressure and keep the gas pressure on the interior liquid level of airtight container 1, make the molten metal crystallization and freezing under elevated pressures effect in die cavity, last piston 5 gos up, remove the gas pressure on liquid level, make not solidified molten metal in stalk road 2 rely on deadweight to flow back in crucible, open form is taken out foundry goods.
Every technical staff's notice: although the utility model describes according to above-mentioned detailed description of the invention; but invention thought of the present utility model is not limited in this utility model; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
