Abstract
The invention provides an evaporative-pattern magnetic mold casting method. Firstly, polystyrene is prepared to an evaporative pattern after being foamed; paint coats the surface of the evaporative pattern, and a gate position is left in the surface of the evaporative pattern; secondly, molding sand is replaced by magnetic shots or iron shots; the evaporative pattern is buried in a magnetic shot box; the magnetic shots are tightened through slight vibration; the magnetic shot box is pushed in a horseshoe electromagnet through magnetic excitation; the magnetic shots are magnetized by a magnetic field generated by the horseshoe electromagnet after electrification; under the effect of magnetic force, the magnetic shots are mutually attracted to form a casting mold consisting of the magnetic shots; a high-temperature metal liquid is injected into a cavity of a magnetic mold to burn and vaporize the evaporative pattern, and fills the whole cavity; and when a casting is cooled and condensed, a power supply is cut off so that the magnetic field force disappears, the magnetic shots automatically drop down, and the casting is automatically taken out.
Description
Technical field
The present invention relates to a kind of vaporization mould magnetic molding process method, belong to field of mechanical technique.
Background technology
Existing vaporization mold casting method generally adopts sand casting, the sand casting fash that out product has die joint to cause, and surface quality of continuous castings needs further to process, and its sand casting has the harm that dust causes, and Modeling Material can not Reusability.
Summary of the invention
The invention provides a kind of vaporization mould magnetic molding process method, can overcome the above defect, without molding sand, the harm causing without dust, Modeling Material can Reusability, the fash also causing without die joint, surface quality of continuous castings is good.
For solving above technical problem, the invention provides following technical scheme: a kind of vaporization mould magnetic molding process method, first will make vaporization mould after foamed polystyrene, and vaporization mould surface is coated with coating, and leaves gate location; The second use magnetic ball or shot replace molding sand, vaporization mould is imbedded to magnetic ball case, and slight vibration consolidation magnetic ball, excitatory magnetic ball case is pushed in horseshoe electromagnet, after energising, the magnetic field that horseshoe electromagnet produces is the magnetization of magnetic ball, under magneticaction, magnetic ball attracts each other, and forms the casting mold of magnetic ball composition; The metal liquid of high temperature is injected to magnetic type die cavity along cast gate, and vaporization mould is burnt vaporization by the molten metal of high temperature, and liquid metals fills whole die cavity; When after foundry goods cooled and solidified, to cut off the electricity supply magnetic field force is disappeared, magnetic ball falls automatically, and foundry goods is deviate from voluntarily.
Further, the container of ethanol is housed in magnetic ball case outer setting, magnetic ball case communicates with this container.
This vaporization mould magnetic molding process method the present invention relates to, respond well, be applicable to the part of medium and small type, without molding sand, the harm causing without dust, Modeling Material can Reusability, the fash also causing without die joint, surface quality of continuous castings is good.
Detailed description of the invention
A kind of vaporization mould magnetic molding process method, first will make vaporization mould after foamed polystyrene, and vaporization mould surface is coated with coating, and leaves gate location; The second use magnetic ball or shot replace molding sand, vaporization mould is imbedded to magnetic ball case, and slight vibration consolidation magnetic ball, excitatory magnetic ball case is pushed in horseshoe electromagnet, after energising, the magnetic field that horseshoe electromagnet produces is the magnetization of magnetic ball, under magneticaction, magnetic ball attracts each other, and forms the casting mold of magnetic ball composition; The metal liquid of high temperature is injected to magnetic type die cavity along cast gate, and vaporization mould is burnt vaporization by the molten metal of high temperature, and liquid metals fills whole die cavity; When after foundry goods cooled and solidified, to cut off the electricity supply magnetic field force is disappeared, magnetic ball falls automatically, and foundry goods is deviate from voluntarily.
The container that ethanol is housed in magnetic ball case outer setting, magnetic ball case communicates with this container.This kind of mode can solve in its production process, the toluene that polystyrene burning generates, and toluene low toxicity, irritant, if put in the middle of atmosphere, contaminated environment, it is water insoluble, but mix with ethanol, its magnetic ball case is communicated with the container that ethanol is housed, absorbed and mix by ethanol.Actual in concrete production process, be arranged on outward in closed container at magnetic ball case, be connected with the container that ethanol is housed at this closed container, connecting line between the two is provided with air intake device, such as air blast etc., the toluene gas of emitting in magnetic ball case can be sucked and is equipped with in the container of ethanol, free from environmental pollution.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any amendment that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
