Abstract
The invention relates to a core making device with an insulating gas blowing cover. The device comprises a core mold, a core shooting mechanism for the core shooting of the core mold, and a gas blowing mechanism for blowing catalytic gas to a sand core formed in the core mold, wherein the gas blowing mechanism comprises a gas source and the gas blowing cover communicated with the gas source; the gas blowing cover covers the core mold and forms a gas inlet space with the core mold; the catalytic gas is blown to the core mold through the gas inlet space; a heating insulating layer is formed in the gas blowing cover and comprises an insulating layer, a heating cable and a metal framework; and the heating cable is fixed with the insulating layer through the metal framework. The device can effectively keep the catalytic gas entering the core mold at a high temperature point required by a process, and can avoid the condition that the curing effect of the sand core is unstably changed because the temperature of the catalytic gas is changed by a normal temperature environment outside.
Description
Technical field
The present invention relates to the coremaking device, particularly relate to a kind of coremaking device that insulation is blown and covered that has.
Background technology
The air blowing cover is the main building block of coremaking device, and the cover of in core manufacturing craft, blowing forms confined space above will being pressed on mould, has corresponding catalytic gas through this air blowing cover entering mould core to be solidified then and plays catalytic action.
The air blowing cover structure of prior art is a steel lead frame structure, and does not have insulation and be in the normal temperature attitude.But in coremaking air blowing technical process, often catalytic gas there is temperature requirement; Particularly be useful in the inorganic resin technology; Catalytic gas need reach about 180 ℃, if be in the normal temperature state according to the air blowing cover of present situation, the catalytic gas of high temperature can cool down after getting into the cover of blowing so; The long more gas temperature of duration of ventilation can descend many more, finally influences the solidification effect of core.But present way is to improve the temperature that the initial temperature the method that gets into of gas is difficult to control final entering core, and the high more requirement to pipeline and gas generator of temperature is also high more, influences the stability of air blowing technology.
Summary of the invention
The present invention provides a kind of coremaking device that insulation is blown and covered that has.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of coremaking device that has insulation air blowing cover; Comprise core, described core is carried out the core shooting mechanism of core shooting, the core of moulding in the described core blowed the inflatable body of catalytic gas; Described inflatable body comprises source of the gas, the air blowing cover that is connected with described source of the gas; Described air blowing cover covers on the described core and forms an admission space with described core, catalytic gas in described admission space is blown into described core, the heat tracing layer that is provided with in the described air blowing cover; Described heat tracing layer comprises thermal insulation layer, heating cables and metal framework, and described metal framework fixes described heating cables and thermal insulation layer.
Preferably, described heat tracing layer is arranged on the internal face of described air blowing cover.Further preferably, described thermal insulation layer is arranged on the described internal face.
Preferably, described thermal insulation layer is asbestos.
Preferably, described heat tracing layer also is provided with the temperature control system of its temperature of control.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
The present invention can effectively keep getting into the high temperature dot that catalytic gas temperature in the core is in technological requirement, can not change the catalytic gas temperature because of the normal temperature environment in the external world and causes the variation of core solidification effect unstable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is an A portion enlarged drawing in the accompanying drawing 1.
Wherein: 1, air blowing cover; 2, heat tracing layer; 3, catalysis gas air inlet; 4, core; 5, core; 6, admission space; 7, thermal insulation layer; 8, heating cables; 9, metal framework.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
A kind of blow coremaking device of cover of insulation that has as shown in the figure comprises core 4, core 4 is carried out the core shooting mechanism (not shown) of core shooting, the core 5 of moulding in the core 4 blowed the inflatable body of catalytic gas.Wherein: the air blowing cover 1 that inflatable body comprises source of the gas, is connected with source of the gas, the cover 1 of blowing cover on the core 4 and and core 4 between form an admission space 6, offer gas hole on the core 4 and be connected with admission space 6.
The heat tracing layer 2 that the internal face of air blowing cover 1 is provided with, heat tracing layer 2 comprises thermal insulation layer 7, heating cables 8 and metal framework 9.Use the thermal insulation layer 7 of asbestos insulation material to completely cut off heats at cover 1 inwall of blowing to cover 1 and the extraneous transmission of blowing; Be fixed on heating cables 8 through metal framework 9 thermal insulation layer 7 times of asbestos again; Be convenient to heating cables 8 through the temperature in the heat transmission lifting air blowing cover 1 of metal framework 9; In addition, heat tracing layer 2 also is provided with the temperature control system of its temperature of control.
Below the concrete method of operating of present embodiment down of setting forth:
Form core through penetrating sand mechanism to penetrating sand in the core 4; Source of the gas provides catalytic gas that core is cured air blowing; Detailed: the catalytic gas after the heating is blown into admission space 6 from the catalysis gas air inlet 3 of the cover 1 of blowing, at this moment, when the temperature of the temperature in the admission space 6 and catalytic gas consistent or near the time; The thermal insulation layer 7 of heat tracing layer 2 can keep the temperature of this admission space 6; When catalytic gas got into core 4, the temperature of catalytic gas descends can be very not big so, just can not impact the solidification effect of cores in the core 4; Temperature in admission space 6 descends; When being lower than the temperature of catalytic gas; The heating cables 8 of heat tracing layer 2 heats; Heat transmission through metal framework 9 promotes the temperature in the cover 1 of blowing, and makes the temperature in the admission space 6 approaching with the temperature of catalytic gas, and its temperature is just monitored through temperature control system in real time.Like this, all the time guaranteeing blows covers the state that 1 inside is in a heating and insulation.
The foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
