Abstract
The invention discloses an automatic thermostatic metal pouring die, which is characterized in that different positions of a high-temperature resisting metal die 1 are provided with closed cavities, a certain amount of required low-melting metal 2 is filled in the closed cavities, the interior of the low-melting metal is provided with netlike conduits 3, and gas or liquid is used as a medium. The die has the characteristics that: because a cooling system formed by the low-melting metal can quickly absorb heat energy and keep the die in a thermostatic state, severe raise of the temperature of the metal die in short time during pouring is avoided, the metal die is ensured not to be mutually sintered with liquid of a high-temperature metal component 4 to cause demoulding incapability, the metal die 1 also avoids generating severe deformation due to temperature difference to be discarded, the service life of the die is prolonged, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of automatic thermostatic metal pouring die.
Background technology
Chinese patent 91103717.9 discloses a kind of measure of casting method and protection metal die model of metal die; Its main feature is by being installed in fluid or water cooling system in the type body of metal pattern model, and the mode of utilizing fluid or water that temperature is taken away realizes lowering the temperature and protects the metal die model.
Summary of the invention
The purpose of this invention is to provide a kind of automatic thermostatic metal pouring die.
The diverse location that technical program of the present invention lies in the refractory metal mould is provided with the chamber of sealing, and a certain amount of required low-melting-point metal is housed in the enclosed cavity, but also in the inside of low-melting-point metal the netted pipe of dredging is installed, and with gas or liquid as medium.When being poured into high-temperature metal iron, steel or other high temperature alloy liquation, the heat energy that low-melting-point metal is come biography absorbs rapidly, transfer out in the mold by netted gas or the liquid of dredging in the pipe that is installed in low-melting-point metal inside again and inhale the partial heat energy that comes, thereby make low-melting-point metal have the characteristic that keeps steady temperature, promptly also make metal pattern can keep temperature constant state; Thereby realized casting to the strict special component of some casting temperatures.
Because the cooling system that low-melting-point metal is formed can absorb heat energy rapidly, and can keep mould at temperature constant state, then avoided the temperature of metal die in casting process reaching acutely rising in the short time, thereby guaranteed metal die itself not can with the mutual sintering of the liquid of high-temperature metal member, and can't the demoulding; Also avoid metal die because the temperature difference produces drastic deformation, mould has been scrapped, thereby prolonged the life-span of mould, reduced cost.
Fig. 1 is a casting mold structure cutaway view of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to shown in Figure 1, the diverse location that technical program of the present invention lies in refractory metal mould 1 is provided with the chamber of sealing, a certain amount of required low-melting-point metal 2 is housed in the enclosed cavity, but also the netted pipe 3 of dredging is installed in the inside of low-melting-point metal, and with gas or liquid as medium.When being poured into high-temperature metal iron, steel or other high temperature alloy liquation, the heat energy that low-melting-point metal 2 is come biography absorbs rapidly, transfer out in mould 1 body by netted gas or the liquid of dredging in the pipe 3 that is installed in low-melting-point metal 2 inside again and inhale the partial heat energy that comes, thereby make low-melting-point metal 2 have the characteristic that keeps steady temperature, promptly also make metal pattern can keep temperature constant state; Thereby realized casting to the strict special component of some casting temperatures.
Because the cooling system that low-melting-point metal is formed can absorb heat energy rapidly, and can keep mould at temperature constant state, then avoided the temperature of metal die in casting process reaching acutely rising in the short time, thereby guaranteed metal die itself not can with the mutual sintering of the liquid of high-temperature metal member 4, and can't the demoulding; Also avoid metal die 1 because the temperature difference produces drastic deformation, mould has been scrapped, thereby prolonged the life-span of mould, reduced cost.
Claims (4)
1, a kind of automatic thermostatic metal pouring die, its feature part is that the diverse location of refractory metal mould 1 is provided with the chamber of sealing, a certain amount of required low-melting-point metal 2 is housed in the enclosed cavity, but also the netted pipe 3 of dredging is installed in the inside of low-melting-point metal, and with gas or liquid as medium.
2, according to the described low-melting-point metal 2 of claim 1, netted pipe 3 and the medium dredged, its feature part is when being poured into the high-temperature metal liquation, the heat energy that low-melting-point metal 2 is come biography absorbs rapidly, and the partial heat energy that absorbs is transferred out in mould 1 body by netted gas or the liquid of dredging in the pipe 3 that is installed in low-melting-point metal 2 inside again, make low-melting-point metal 2 have the characteristic that keeps steady temperature, also make metal pattern can keep temperature constant state.
3, can keep temperature constant state according to the described metal pattern of claim 2, its feature part is to have realized the casting to the strict special component of some casting temperatures.
4, can keep temperature constant state according to the described metal pattern of claim 2, its feature part is to have avoided the temperature of metal die in casting process reaching acutely rising in the short time, guarantee metal die itself not can with the mutual sintering of the liquid of high-temperature metal member 4, and can't the demoulding; Also avoid metal die 1 because the temperature difference produces drastic deformation, mould is scrapped prolonged the life-span of mould, reduce cost.
