For overcoming above deficiency, the pressure casting apparatus that the utility model provides a kind of structure simple, easy to use, to realize good product quality, production efficiency is high.
The utility model is realized by following technical proposal: a kind of pressure casting apparatus, comprise the crucible that top is with cover, bottom belt exports, be arranged on the heater of crucible periphery, and the mould of belt type cavity, wherein, crucible bottom outlet is communicated with the die cavity of mould by pipeline, and on pipeline, be provided with force (forcing) pump and exhaust tube, the pipeline of the outlet of described connection crucible bottom and force (forcing) pump is provided with control valve, connect the pipeline of force (forcing) pump and die cavity is provided with valve, and exhaust tube is located on the duct wall of die cavity arrival end.
The position of described mould, lower than the position of crucible, makes molten metal can be full of die cavity completely under gravity.
Described force (forcing) pump is driven by torque motor, and is electrically connected with conventional controller, for controlling force (forcing) pump action, to increase the pressure of pipeline inner metal liquid body, makes molten metal be full of die cavity, improves formed product rate.
Described exhaust tube is connected with conventional air-extractor.
Establishing check valve in described exhaust tube, and be electrically connected with air-extractor, for controlling air-extractor, ducted gas being extracted out, avoid product to produce bubble.
The coated insulation material of described pipeline outer wall.
Inflation inlet is established on described crucible top, for being filled with protective gas.
This pressure casting apparatus, when carrying out compression casting, is following operation:
A, by mould and die preheating, clamping, check the connection of miscellaneous part;
B, open control valve and valve, by exhaust tube, pipeline is bled, extract the air in mould and crucible out, then closed control valve;
C, open the lid of crucible top, metalliferous material to be cast is dropped in crucible, start heater and melting is carried out to metalliferous material, make the metalliferous material in crucible be melted to liquid state;
D, open control valve, make crucible inner metal liquid body flow in the die cavity in mould through piping; Period, start force (forcing) pump, increase the pressure of pipeline inner metal liquid body, impel ducted metal liquid to flow in the die cavity of mould;
E, valve-off, and stop force (forcing) pump, after the metal liquid in die cavity solidifies, open mould, take out cast article.
The advantage that the utility model possesses and effect: the utility model by arranging force (forcing) pump on cast pipeline, increase the pressure of pipeline inner metal liquid body, and exhaust tube is set, reduce the air content in casting system, can by the rotating speed of control pump, steady increase manifold pressure, and rotating speed and pressure proportional, be easy to control pipeline pressure size; Force to discharge the air in mold cavity and melting kettle by exhaust tube, avoid oxidation during metalliferous material heat fused, be conducive in flow direction of material mould, pore-free in the product cast out made.By foundry goods prepared by the utility model, crystal grain is comparatively thin, smooth surface, and size is accurate, and properties for follow is good.It is high that the utility model has yield rate, and technique is simple, the advantages such as cost is lower.
